Sound Master Memory Rhythm SR-88

Interesting item popped up for auction. As usual, I have no affiliation with the seller or the auction. Just pulling the shots and info for posterity. Title link takes you to more shots.

"Produced in the early 80's - from the same era as the Roland Boss DR-55. Controversy still rages as to who copied who - Boss or Sound Master?

It's totally analogue and is in SUPERB condition, with it's original box, owners manual and sample-pattern book.

There are 6 x 16-step (4/4) patterns and 2 x 12-step (3/4 or 6/8) patterns, with A and B variations of each. You can play just A, just B, A followed by B or A then B every 4,8 or 16 bars (like a fill-in).

There are 4 totally analogue and groovy voices - Kick, Snare, Closed Hat and Cymbal (actually more like Open-Hat).

There is a foot-switch input for stop-start and, for you sequencer-heads, a Clock Out +5v trigger on every pulse or every Cymbal beat.

It runs on four Walkman batteries or an AC adaptor (not included)."


  1. I had one of these in the eighties. I sold if off then later regretted it and purchased another one. It's fun and cheesy, but the sounds are really nothing to write home about.

    I currently also have a soundmaster SR-1 which has presets only. If you're paying more than about $40 for an SR-88 you're paying too much.

  2. yes, i just put trigger-inputs on each voice and made the bassdrum more punchy. the voices are triggered by a simple +5V source. the kick doesn't have a sustain if you put a long trigger on it but the other voices make the sound as long as you put the trigger on. the volume of the voice depends on the voltage of the trigger so you can put an adsr on the trigger to make really interesting sounds! this machine is just amazing if you put some effort in.

  3. indeed, jw. it's funny how the sound from my stix changes if i put a trigger in the input !

    never tried the adsr thing, sounds very intrsting.
    with another clock in the snare sounds like a 909 snare.

    allso : putting more pressure on the battery thing the sound changes too.
    shaking with it makes the cymbal detune !

    fun thing

  4. I am looking for one of these drum machines!
