Roland/    Studio     Electronics     SE-02  Monophonic    Analog      Syntheisizer

                                                                                  A collaborative effort merging Studio Electronic's SE-1x    ( -discrete analog circuitry and signal flow ) with Roland's miniaturization, sequencer and cross-mod acumen. The SE-02 is the first of Roland's Boutique "Designer Series".

In     the     Behringer     "Crave     3"     Synth     Poll     below!


Having previously owned Roland's JP-08, JX-03 and JU-06 Boutique synths ( -which I've since jettisoned ),          I didn't know what to expect from the SE-02. However, as a fan of old-school, one-knob-per-function "reach-out-and-tweak it" analog synths, the SE-02's irresistible knob, switch and button festooned control panel finally lured me into buying it.  Since acquiring it I've found the SE-02 to be a "mixed bag" of good combined with a fair amount of "Gee, I wish they'd done that betters". We'll get into both the "goods" and the "Gee, I wished's" in the following review. 


                                                                                                  The ACB ( -Analog Circuit Behavior ) modelling technology used in Roland's Boutique line is fairly decent sounding. Of the aforement-ioned trio of Boutiques, I found the JX-03 to be the best sounding of the lot.  So, HOW does the ( newer ) SE-02's tone measure up against these earlier ACB-powered Boutiques?  I'd say it "bests them" but        ( -somewhat surprisingly ) not by that much.  To be honest, the           ( -ABOVE  )  ROLAND'S  BOUTIQUES     SE-02 is a bit of a let down.  At least in terms of sound quality. 

A     listing     of     features:

The SE-02 is a discrete analog ( 3 ) oscillator monophonic synth. Each of it's oscillators sport ( 6 ) waveforms      ( -they are:  triangle, tri-saw, sawtooth and three pulse-width/ squares -with the last qualifying perhaps as an honest-to-goodness pulse wave ).  Oscillator three substitutes a traditional reverse sawtooth for the "tri/saw" wave featured on the other two oscillators -just as the old Minimoog did. 


The oscillators are temperature-stabilized and auto-tune for drift free operation. The last time I checked, Behringer's "D" ( -a synth that might be considered a competitor to the SE-02 ), didn't offer this degree of stabilization -requiring owners to manually calibrate it's oscillators before serious usage. However, this may have changed since I received my early-production "D" months ago. Perhaps Behringer has caught on that customers shouldn't have to calibrate things that should be done on the production line. Let's hope so. 

"To     be     honest,    the     SE-02     is     a     bit                of     a    let     down.     At     least     in     terms                          of     sound     quality"     -Tomm    (  CTN  ).

Filters, cross-modulation and more...

The SE-02 also features a 24 dB/ octave "Moog-style"    low-pass filter with a filter feedback loop ( -for "fattening up" the sound ). You'll also find a dual gain-stage amplifier for adding some additional "character" to the sound. Three types of cross-modulation are provided for ( i.e:  02-Filter, 03-02 and 03-PWM ) and like the filter there's a feedback loop. PLUS a noise generator -to expand your sonic palette even further!                                                         ( -ABOVE  )  THE  SE-02  LOOKING  SEXY  IN  THE  STUDIO

LFO,    sequencer   and such...

The SE-02's tempo-syncing LFO has ( 9 ) waveforms ( i.e:  the all-important sine, a triangle, a ramp, a saw-tooth, ( 3 ) square waves ( -of decreasing duty-cycles ) and two versions of "random".  There's a tempo-syncing digital delay with "bypass" ( -to maintain the SE-02's pure analog signal path for the purists out there ), along  with a generous ( 384 ) factory presets. Thankfully, there are ( 128 ) user patch slots left "open" for those of      us who still prefer to "roll our own". 

( -LEFT  ) THE  SE-02's  SEQUENCER  SECTION                ( -buttons at the bottom of the control panel ) 


There's a 16-step pattern sequencer ( -which can sync  to external tempo via MIDI, USB or trigger input ). The sequencer can be used for sequencing notes, gates, glides and other synth parameters -via it's somewhat irksome "step-entry" procedure.                                    ( -ABOVE  ) THE  SE-02's  SEQUENCER  SECTION 

More    sequencer    stuff,    I/O    connectivity                                                                 and     other     "sonic     goodies"

Patch numbers are stored with each sequence and up to ( 128 ) sequences are storable ( -allowing you to construct longer songs with 16 parts ).  Synth parameters can be "sequencer automated" by pressing a step button and then moving a synth parameter control to where you want it -then repeating this process over-and  -over again, for as many steps as you want your sequenced parameter automation to last. Frankly, IK Mulit-media's UNO Synth makes doing this is a lot easier  ( -and it costs half  of what the the SE-02 costs! ). 

"Frankly,    IK     Multimedia's     UNO     Synth   makes    doing     this     ( i.e:     "sequencer     automation"     of     synth     parameters    )        a     lot     easier (   -and    it    costs     half     of    what     the     SE-02      costs! )"                                                                                                                                                                                                                                                                                                                                                                          -Tomm,  CTN.

Sequencer,     goodies     continued...

The SE-02's sequencer allows you to set shuffle, scale, direction and set your sequnce's first and last steps.  Nice touches!  Along the unit's top apron you'll find standard MIDI, USB-MIDI and USB-Audio ports along with GRRRRRR!  a plethora of slightly protruding ( -flimsy lookimg ) 1/8" mini-jacks ( -for trigger I/O's, CV inputs,    an external audio input -for routing external audio through the SE-02's filter, a stereo audio output along with  a headphone jack ).  Need I mention my disappointment at seeing cheesy 1/8" mini-jacks being utilized for these "mission critical" I/O's?  And yeah, I know the 1/8" mini-jack has become the de-facto "standard"        for Eurorack and lots of other synths these days but it doesn't make them the optimal choice for signal transmission -especially audio! 


I'm sure the folks at Roland and SE will quickly justify their use citing the unit's diminutive size ( i.e: "We couldn't possibly fit full-size 1/4" jacks on a unit this size!" ).  However, I'm not sure I'm buying that. I think    it's more likely they simply wanted to "cut corners" and use the unit's size as a "ready-made excuse" to save      a few bucks. Wake up synth manufacturers!  1/8" mini-jacks ( -especially the dreaded 1/8" stereo mini jack, SUCK S BIG TIME! ).  They're ALWAYS  the first thing to develop signal intermittancies, audio drop-outs            ( -and subsequently require replacing ).  Employing them on a piece of gear listing for half-a-grand is inexcusable! If you need more mounting room then use a slightly larger chassis so sturdier, proper 1/4" connections can be used!  The sequencer's "chain mode" allows connecting additional SE-02's via MIDI.

Notice all of  the mini-jacks!          One of the SE-02's "Achilles' Heels". How long they'll last before developing signal intermittancies and drop       -outs is anyone's guess. 



Beware of the  K-25m's ribbon connector.                  Once it's connected it's there for good! 

The     K-25m     mini-keyboard

I purchased my SE-02 along with it's optional K-25m keyboard. This two-octave mini-key keyboard was  specifically designed to work with the Boutique line.  Having previously owned the JX-03, JP-08 and JU-06 Boutiqies, the K-25m was old territory.  It's pretty much what you'd expect from a $100.00 mini keyboard controller.  Stubby mini-keys with a clunky, utilitarian keybed.  Nothing special.  Certainly, a far cry from the deluxe silky-smooth action you'll find on Yamaha's "ReFace" line or Novation's "Mininova" for that matter. 


You connect the K-25m's ribbon controller to a multi-pin receptacle on the back of the SE-02 module ( -just      like the other Boutique synths ).  A word of caution:  Once that connector is attached it's there for good!        You won't be able to easily detach it for "mixing and matching" with your other keyboard-less Boutiques.      And I say that from experience!  I've tried  detaching the K-25m's ribbon connector from past Boutiques        and broken fingernails in the process.  I'm sure Roland's techs have a nifty tool that makes "quick work"          of this -but for us mere mortals forget it!  Once again Roland makes it as difficult as possible for customers!


"Once    again,     Roland     makes   it                                            as     difficult     as     possible     for      customers!"        -Tomm,  CTN

The one "saving-grace" the K-25m offers is it's thoughtful three-position locking mechanism. You can      position the SE-02's chassis ( -or any OTHER Boutique synth ) at two different tilt angles or set it flat. A nice touch!  A release button on the back allows you to disengage it from the flat position -but it can sometimes be  a trick to get it to fully disengage. And another word of caution: be careful when tilting it past it's fully upright position ( -because if you go past that position  the weight of your Boutique synth can cause it to flop forward onto the K-25m's keyboard! ). Make sure you're cradling your Boutique module's weight in your hand if        you need to tilt it past this topmost position -to avoid this unwelcome surprise! ).

X-Mods,    factory     presets       and      firmware      updates

The SE-02's "X-Mod" section allows you to apply cross-modulation ( FM ) in the following ways:               


The 02-Filter knob lets oscillator 2 modulate the filter's cut-off frequency. The 03-02 knob lets oscillator            3 modulate oscillator 2's waveform. The 03-PW 1, 2 knob allows oscillator 3 to modulate the pulse-width        of oscillator 1 and 2 ( -their pulse waves only ). Apart from the pulse-width modulation -whose functionality  has been enhanced with a firmware update ( v1.1 ), the rest of the "X-Mod" section could've been omitted completely and I'd never have miss it!  It adds little -save a few abberent tonalities. A waste of control panel space in my opinion. 


Luckily, the pulse-width modulation has been improved with v1.1's firmware update ( -though getting it to    work using the firmware's "button-press gymnastics" is a bit tiresome ). The unit comes with ( 384 ) factory presets. What can I say -they're "factory presets"! They sound as if the programmer who cobbled them together did so as quickly as he could ( -with many sounding similar to the ones proceeding them ). Nothing inspiring here.  I think I found exactly ONE ( # 65 ), that I might actually use - if I were desperate. My advice: program your own -they've gotta be better  than any of these!

( -RIGHT  ) STUDIO  ELECTRONICS  SE-1x                                                            Inspiration for and full-sized                forerunner of the SE-02.


Initially, upon hearing the SE-02 for the first time, most synthesists give it their "thumbs up". I did too! However, within a few minutes of hearing it my initial impression began to sour. I started noticing a certain "sharpness" about it's sound ( -as if everything sounded a semi-tone or two sharper than it should be ). The  high frequencies seemed "hyped" and a bit too saccharine for my tastes.  At the same time the SE-02's low  end seemed a bit "thin-sounding" to me.  After many hours of listening to the SE-02 during the writing of this review, my opinion hasn't changed. If you're looking for a synth to emulate those fat, beefy analog beasts of yesteryear -this may not  be your synth.  

"    If     you're     looking     for     a       synth     to     emulate    those     fat,     beefy     analog       beasts     of       the    yesteryear    -this            may    not     be    your     synth" .                                                                                                                                                                                                                                                                                                                                                                      (  -Tomm/  CTN    )

Proof's     in     the     pudding...

Well into doing this review, I stumbled upon a SonicState review of the SE-02 done by Nick Batt. Near the beginning of his review Nick put the SE-02's raw oscillator waveforms onto an oscilloscope. Upon seeing    them I knew where that "saccharine sweetness" was coming from. The oscilloscope trace tells the story! 


If you happen to watch Nick's review you'll see what I mean. The SE-02's sawtooth waves sound overly "bright" and "thin" ( -with none of the full-throated sawtooth richness you'll hear coming from many vintage analog machines  ). And the SE-02's oscillator's pulse/ square waves tilt at such a pronounced angle the corners of each square appear almost to be sawtooth waves. While Nick found nothing wrong with these distortions -        I did!  The SE-02's "hyped" waveform peakiness and tilted edges ( -on the pulse/ squares ) are bound to      add excess high frequency content to the signal ( -explaining the persistent "saccharine" glaze I was hearing ). This high frequency "glaze" overpowers the low-end content and the ear perceives it as weakened bass or        a "lack of beefiness". Again, the oscilloscope tells the story! 


Curiously, the triangle waves -while exhibiting some lopsided bowing -fared much better and sounded

the most authentic of the SE-02's oscillator waveforms.  And YES, I do understand that few if any synths put out perfectly symmetrical "text-book" waveforms. I also realize waveshapes can be contorted depending upon their frequency ( i.e:  appearing more compressed at high frequencies and more spaced at lower frequencies, etc. ), not to mention the effects of filtering, envelopes, LFO modulation upon the wave's shape. However, these were the raw unfiltered waveforms -coming straight out of the SE-02's oscillators! With oscillators being the sonic "heart" of any synth, these distortions are cause for concern -unless you're into a "hyped" saccharine sound.   

( $50.00  )   PAIA    "Gnome" vs.     ( $500.00 )    "SE-02" !

In 1975-76' PAIA ( -a DIY kit company ) debuted their ( $49.95 ) "Gnome" Micro Synthesizer. Being a teenage kid in highschool at the time I bought and built one. The "Gnome" was only intended  to be a low-cost educational "toy" ( -to teach budding electronic musicians the rudiments of electronic music ). Despite that, the "Gnome" had a very cool oscillator section with triangle, sawtooth and square waves along with a "skew" control knob ( -allowing you to transform the triangle into a sawtooth wave and the square into a pulse wave ). By manually turning this knob back and forth you could approximate pulse-width modulation  of the square wave.  A very cool feature! 


More over, the "Gnome's" oscillator section sounded phenomenally good! Especially it's sawtooth wave.        It's warm, musically rich, full-throated timbre was an absolute joy to listen to. The very essence of what "analog" should sound like!  It's amazing that this $50.00 DIY "kit-built" synthesizer's oscillator section      sounds soooooooooo much better than the one employed in the SE-02!  At 1/10th of the professionally        built SE-02's suggested price, the "Gnome's" oscillator absolutely crushes the SE-02's. By comparison, 

the SE-02's oscillators sound downright "anemic"!  Who'd have guessed?   


AN "UPDATED" GNOME?  WOULD  YOU WANT ONE?  As I've mentioned, with tiny mini-synths like Korg's "Volcas" selling like hotcakes it's insane PAIA hasn't chosen to introduce a ( new ) "updated" "GNOME 2"! 

Here are some of the features I'd love to see a "GNOME 2" incorporate:  First  RETAIN that unique Osc "Skew" control and those repeatable/ looping envelopes!  Add an LFO for auto PWM of the Oscillator.  Add a sub-octave ( square wave ) generator  that tracks the initial oscillator's pitch either one or two octaves down  from the oscillator's pitch.  The "GNOME 2" should also include an easy-to-access "snap-off" back-panel 9 Volt

x 2 battery compartment ( -eliminating the need to unscrew the bottom panel screws and deal with those

flimsy snap-on battery clips! ). 


Equally important:  The trouble prone controller-strip + wired probe and meddlesome ( red ) trigger button      ( -with it's "intermittent contact" problems ) should be replaced with a slick glassine encased mini keyboard panel ( -like the one used on Korg's "Volca Bass"! ) with a keyboard generated trigger/ gate signal. No one  should have to feel their index finger "going numb" -as mine often does  -when continuously pressing the "Gnome's" red "trigger" button ( -just to keep the sound going! ). With these few improvements a ( new )

PAIA "GNOME 2" could ride the crest  of this "tiny synth" craze for years to come!  As we've seen with the skyrocketing sales figures of such mini-synths: there's definitely an eager market out there for such synths!  Especially, if it could be purchased fully-assembled  ( -as most aren't into DIY "kit-building" )

these days!  So, what do YOU think?  Is a PAIA "GNOME 2" a good idea?  Would you buy one? 


*NOTE:  For those who say  PAIA's "FAT MAN" is a rough equivalent to the "Gnome", I have to say:  WHAT?        The "Fat Man" isn't anything  like the "Gnome" ( -either in size, feature set or in it's "go and play it anywhere" battery portability ).  The "Gnome" was truly UNIQUE in 1975' and it STILL IS!  Hopefully, if enough people

ask for it, PAIA will finally see the need and introduce a ( new ) "GNOME 2".  Let's hope so!  

Build    quality:

The SE-02's build quality is another area of concern. Besides the flimsy 1/8" mini-jacks, I found the unit's tiny knobs "tweezy" and stiff ( -especially it's waveform selection knobs ). Hopefully, this stiffness will work itself out over time. The unit's tiny switches don't inspire much confidence either. They are so tiny and fragile-looking! Whether they'll withstand repeated switching over time concerns me. Ditto that concern for repeated plugging in and disconnection using those already mentioned 1/8" jacks!  At this price point, I would've thought that  Roland and Studio Electronics could've sourced much higher quality parts. 


Frankly, the build quality of the SE-02 worries me. Will I be sending it back for repairs in a couple of months?    Only time will tell. I wish I could be more positive but all of these component compromises worry me.


And there's another thing:  the operation  of the SE-02 isn't what I'd call intuitive, straight-forward or user-friendly, especially the "firmware-updated" features. Be prepared to be glued to the owner's manual for   

a while until you master all of the SE-02's "button-press gymnastics". It's almost as if Roland's design team wanted to make things as vexing and irksome as possible for the end user. You even have to follow a specific procedure just to turn the unit on and off! I remember encountering this "turn on" and "turn off" protocol decades ago with my very first Roland product -Roland's MSQ-700 Sequencer.  I recall thinking: "Are you kidding me? I can't even turn this thing on or off without referring to the manual?" I thought it was stupid    then and still do.  After ( 30 ) years, Roland still puts it's customers through this stupid nonsense.

Wake up Roland!  STOP making your equipment such a "pain-in-the-ass" to operate!  

Some     better     "alternatives"

As has been the case with every Roland product I've ever owned, I plan to get rid of the SE-02. I'll be replacing  it with a better-sounding, better built  synth that employs a more intuitive, user-friendly design. Are there any viable "alternatives" to the SE-02 currently on the market? YES, there most definitely are! Here are a few you might consider. Check them out. Watch ( -and listen to ) to a few YouTube videos demoing these units.              I think you'll see that you can do a lot better!  



I think most would consider Behringer's "D" to be the SE-02's foremost competitor. Having owned a "D" for a short time I'd agree. They both cover a lot of the same sonic ground. However, since I ditched my "D" ( -didn't want to risk voiding it's warranty trying to calibrate it's "drifty" oscillators myself ), I don't think it fair to comment as I was hearing the "D" at it's worst ( i.e:  with un-calibrated  oscillators ). 

                           ( -RIGHT  )  ELECTRONIC  MUSIC  WORKS'  "WCS-1x"                                                                                                            The Brazilian made WCS-1x "Wave Composition Synthesizer" ( -available from Perfect Circuit Audio for $299.00 the last time I checked ), certainly gives the SE-02 a run for it's money! Surprisingly, even with it's digital oscillator ( -the remainder of it's signal path being discrete analog ), the "WCS-1x" has a convincingly "Moog-like" sound. None of the SE-02's "hyped" saccharine -sounding "faux analog" pretenses. The "WCS-1x's" warm, musical and beefy sound is about as authentically "old-school" as you'll find in this price range. I liked it's full-bodied "old-school" sound so much I bought a "pair" of them for myself!  If you want to experience "analog heaven" on a beer-budget connect an Arturia "Key Step" keyboard controller's MIDI output to a MIDI Solutions "QuadraThru" ( 1-in-4-out ) MIDI splitter box so you can program and play "combined patches" on a pair of these puppies.  Absolutely incredible sounding! You can read my full review of Electronic Music Work's "WCS-1x" here:   EMW "WCS-1x" Wave Composition Synthesizer" Review



New  on the scene:  Behringer's ( new ) "Crave" Mono Synth ( -employing a single 3340 Oscillator, a Moog-style filter, an innovative sequencer and extensive patch bay I/O's on GRRRR! 1/8" minijacks  ). The demos I've heard of the "Crave" sound great despite it's being "crippled" with a single oscillator.  At it's alluring ( $199.99 list price ), the "Crave" is bound to sell briskly. If Behringer was smart  they'll quickly follow-up the "Crave" with a ( 3 x 3340 Oscillator, 3 x LFO ) "Crave 3", so you could pulse-width modulate one or more of the 3340 oscillators at different LFO speeds while the other LFO ( s )  modulate filter cut-off, VCO pitch, etc., at independently programmable LFO rates.  A "Crave 3" ( -boasting  these features ) would sell like crazy!  While It's just a "hunch" on my part -a "Crave 3" just makes too much sense NOT  to be currently "on the drawing boards" at Behringer.  If it is, I know what I'll be replacing  my      Roland SE-02 with!

( -RIGHT  )  YAMAHA'S        REFACE  "CS"  SYNTHESIZER                                             Yamaha's svelte ReFace "CS"  ( -with it's compact, sturdily built 3-octave mini-keyboard ) is a viable competitor though  it doesn't offer anywhere near the SE-02's sonic features.  What IT DOES have that the SE-02 sorely lacks is great sound-quality.  Well, let me clarify that a bit. The"CS" offers ( 5 ) different Oscillator Modes. Of those, the bottom "Supersaw" Oscillator  Mode ( -with it's two multi-sawtooth waves and pulse-width modulated square wave ) provides an incredible bass foundation. The SE-02 can't come close to matching it. Using this "Supersaw" mode and the "CS's" filter yields gorgeously fat and rich sounds. Problem is, the "CS" is a "one trick pony". This "Supersaw" Oscillator Mode is the ONLY oscillator mode that sounds good. The other four modes could've been left off altogether and I'd have never missed them.  And using this one mode makes for a rather limited sonic palette. 


In it's favor, the Yamaha "CS's" beautifully compact size, design and small "footprint" make it perfect for      "on-the-go" mobility ( -as does it's 6 x AA powering option ). It's 3-octave mini-keyboard has a deluxe feeling keybed rare in it's price range. In fact, these aspects of the ReFace "CS" inspired me to design the "Grab n' Go Workstation Keyboard" design pictured below -which packages a full-featured workstation into a chassis having the identical dimensionsweight and AC/DC mobility of the "CS".  You can read more about it by clicking on this "Grab n' Go Workstation" link and scrolling down the page. If you'd like to read my full review of the "CS" click the following "Yamaha CS" link. 


Based upon the Yamaha CS's svelte dimensions, weight and three octave mini-keyboard. Hopefully, some forward-thinking synth manufacturer will see my design and make it! 


So, what can I say about the RolandStudio Electronics' SE-02?  Honestly, I thought I'd be writing a very  positive review on it based upon my initial impressions. However, once I actually had one in front of me to test my first impressions were dashed by it's underwhelming sound, worrisome build-quality and less than optimal implementation of features ( -companies shouldn't rely so heavily upon firmware updates to "get it right" after the fact! ). The SE-02's less than intuitive design and irksome operation ( -as described above ) didn't help matters either. 


So, I can't give the SE-02 my full-throated endorsement. There are just too many features that could've been designed and implemented better. And again, the quality of parts ( i.e:  knobs, switches, 1/8" mini-jacks, etc. ) leaves much to be desired -especially considering the unit's list price.  In conclusion, I'd recommend giving    the SE-02 a "pass" and checking out some of the "alternatives" I've listed above. If you're after genuine        "old-school" analog sound I think ANY of these "alternatives" will get you closer to the mark.
