Autoglide = on!
SH101 Mod
slightly modified .. the sh101 has a little 256-step sequencer and it's LFO can trigger the env, 1 VCO but has SubOSC 1 or 2 Octaves below the main VCO. fat sounding ..

nice simple sequencer can hold up to 256 notes. very simple but helpful, even for live purpose.

choose gate or the envelope to be the env form, mix independently saw, pulse and the subosc: the sub osc can also be set to 2 octaves below the main VCO!

the filter is a 24dB / oct roland type LPF, since it can be used with batteries and was "small" it was a great instrument for live gigs and techno sets .. well it still is ..

MC202 - is nearly the same sound "engine".
so imagine the mc 202 as sh 101 but no noise generator, the lfo can't mod the VCA and the LFO waves random and square are gone.

the sequencer is a quantizing real time and / or step by step sequencer that offers 2 channels (CV) to be controlled .. not bad but it is always quantized (steps!).

Rolands head, mr kakehashi was always quite innovative, so roland made a compusynth that featured the sound engine of the sh101 .. or to be exact: the mc202: the CMU810 has sliders but no keyboard in a white case to be controlled externally or by computer via CV .. it is quite exotic today ..

here you can see the sh101 panel ...
LFO can trigger the ENV !!

thats the sh101's mod section: quite big! the bender and portamento and switch for "auto portamento", transposition and mod amounts of the bender (vcf, vco can be modulated by the bender and of course the LFO mod. amount itself)

sh101, quite like the mc202 and CMU810 - CMU810 - a "computer controlled" sh101-kind of white box with sliders .. quite like the sh101 but no sequencer, lfo with delay but without retrigger for env. but it's almost the same circuitry as the sh-101

SH101 + MC202 + CMU810 test
TEST: Roland SH101 + MC202 analog synthesizer
+ Roland MC202 synthesizer / composer / sequencer + CMU810 computer synth module

Back to 1983. Papa Roland launched a small synthesizer in gray, blue and red for the highly competitive monophonic synthesizer market. What the little one still has: It is one of the rare synthesizers that can be operated with batteries (6x â € œBabyâ € 1.5V (these things are often found in ghetto blasters)). Of course it is a specialty, because attentive readers will surely know that 1983 was no longer the year of the monophones for a long time.
And: it's THE SH101, S for synthesizer;) THE synthesizer that nobody comes to me with "the sh101";) * grin *

Pictures: below !!!

who? mc202 + cmu810 is / are technically very identical .. further below ..;)

As a special accessory there is a â € œguitar-likeâ € handle that contains an additional controller .. and there is a strap holder.

What can little 2 1/2 octave Roland do?


There is an oscillator that offers the waveforms (typical for SH series) sawtooth and rectangle separately adjustable in volume. There is also a pulse width regulator that adjusts the symmetry of the square wave. (see Synthesizer Glossary here or at The pulse width can be modulated by LFO, the envelope or manually. And that's not all, there is a sub-oscillator which, like the waveforms, can be infinitely adjusted. Normal sub-oscillators usually have hardly any control elements, but the SH 101 is different: With a selector switch, its usual (square-wave) tuning, namely an octave below the main oscillator, can also be 2 octaves lower and the same with 25% â € "duty cycle" (ie: the square wave is asymmetrical and has 25% in the positive and 75% of the wave in the negative).
These are joined by the obligatory modulation control of the LFO on "the" (the !!) oscillator (s) for vibrato and the foot switch (2 ', 4', 8 ', 16').
In order not to use the clichéd phrase â € œthe control for white noise rounds off the oscillator sectionâ € a good impression remains for them, because it sounds really good and powerful for a portable synthesizer.


There is an LFO and oscillates with rectangle, triangle or random waves, whereby there is also a noise setting that is suitable for generating rather coarse “dirt heaps”. Here, however, the speed controller remains redundant, while the random setting does this very well considered. This is the usual implementation, so don't panic and get your fingers out of the socket / beer bottle.


Now what everyone wants to know: Filters, of course .. to say it in advance sound as expected, a 24dB / Oct. not dissimilar to the TB303. Low-pass filter can be used by LFO, envelope, keyboard (opens when higher keys played) and offers resonance up to self-oscillation.

There is a very fast envelope curve with ADSR characteristics, which has a special but nice addition: It can be retriggered (started) by the LFO, there is also a re-trigger with every keystroke or the normal "monophonic" Trigger mode â € œ which does not restart the envelope when playing legato (interesting for portamento effects). Portamento? Was that? Dragging the pitch to another pressed key (legato). The time that this takes can be set, there is also a mode called "Auto", in which this portamento effect only pulls the pitch when playing the legato. A very musical thing.

The VCA offers the option of using the filter envelope, but it is also possible that this is set to Gate, because the volume envelope is given an â € œorgel characterâ € so simply switch it on with the button pressed and ??? yes switching off happens of course when the button is released.

But that wasn't all. There is a transpose switch with 3 positions and of course it sets the keyboard 1 octave lower (or higher). There is also a pitch bender that also allows the oscillator to be modulated by pressing the LFO (popularly: vibrato) upwards. The bender can also influence the filter cutoff, since the range is adjustable, so there are 2 controls for the intensity of the pitch and filter (corner) frequency.

That would make a great performance synth, wouldn't it?

But that wasn’t all. There are two more features:

Arpeggiator and Sequencer

The arpeggiator is easy to explain: it and the sequencer are triggered by the LFO and the chords held are played either up or down, or both in a row.
It's incredibly easy to do and deserves a live point. It's just as easy with the sequencer: press Load and play in, you create a pause with the Rest button or press the Legato button, which of course also produces the trailing sounds with automatic portamento. 100 such dates are possible.

Now do you want to hear that thing? Great: One press of the play button and off you go. If you want to transpose the gnaze, you can: press a key and â € œpress inâ € the new pitch on the keyboard.
It's as easy as it sounds and just great fun.

Just out

There remains the follow-up question at the beginning of other magazines: Yes, we have the MIDI Tri ... ehm .. nonsense !! Well CV and gate in and out, so an Oberheim Xpander can control a master keyboard with it ;-))
This means that MIDIfications are really problem-free (e.g. Doepfer MCV1). In addition you can, very nicely, connect hold and external triggers .. everything is nice and analog.

So if you like it, this little marvel can really easily be built into an analog and digital hodgepodge of trigger-friendly synthesizers. But if you like, you can also have MIDI. it is simply a simple and straightforward and extremely live-capable synthesizer that also sounds good.
Lead out ...

Do you want a red, blue or gray now? Yes, the gray one sounds a bit better since the new OS update and ... um .. well .. no, the test is over. You can currently get such a performer for around 800.00.

Sound collections and the like can be found at, as always

Philip Pilgrim has the most extreme modification of the SH101 I know, here the little one gets another envelope curve, OSC modulation (FM) and lots more crazy ideas .. Info at the Lab .. just â € œNovamodâ € in Google type .. ;-)

PS: Phil doesn't live in Canada anymore ... but in Ireland. If you want to contact me, just email me, he is a little stressed at the moment ..


PS: The sound reproduction of the MC202 is quite similar, only that with the MC a few details are less possible .. but sounds very similar, identical, as long as you consider the following: ..
the noise generator is missing and is equipped with a quantizing sequencer.
and waveforms (in the lfo!) rectangle, random are missing and the vca cannot be modulated by the lfo. so the lfo and noise are the big differences to the "big" sh-101
the sequencer can be used in realtime and step by step and generates 2 CV voltages (internal and one external) in fact this is a bit cumbersome .. but it works and was intended for longer sequences.
but: better than a 303 is a 202 and a 101 anyway;)
all in all, the small part was quite advanced for the time, albeit with a rel. simple sound generation. there is certainly no lack of pressure. alternatively you can take a look at the sh101, which is also battery operated, it can do more, has a sequencer and is a bit more suitable for live use .. (that's certainly a matter of taste)
roland mc202<-- thx="" for="" mc202="" pic="">
THE CMU810 is a very early idea of ​​a white box almost completely equipped with controllers for computer control .. similar to cmu800 well .. in fact it is a sh101 without the LFO trigger of the envelopes.
Of course, it works without a sequencer or arpeggiator.
but for that he has Nolise, just like the sh101 ..
it has a VCA CV control input and even a delay controller for the LFO (fade)

humbly, your devoted
pierced or better your highness ...
