#System100M

2025-03-17

In the back, with cover and reverb tank removed. Bottom 1U has the power supply, a USB port, a strymon level converter and a midi to cv converter (the 3u modules are mounted in abyss devices adapters and adapter mounted to front rails back through long standoffs)

Cables are held in place through plastic clamps, fixed to the vector rails and power bus held by screws.

And that is what a #roland #system100m keyboard looks like. Not to be confused with the system 100 keyboard.

Finished a module to connect my original Roland System 100m keyboard to my system 100m 191J tribute modular. It is a tight fit to get 3 jacks in height on a 1U space. Pulp Logic rail spacing and panel sizing (I don't think I could do this in an intellijel 1u). This is not a midi to CV, it is a din specific to the system 100m with +/- 15V to power the keyboard. It also carries the cv and gate.

Homemade 1U 12hp module to replicate the bottom left part of a Roland System 100m 191j chassis

@Jyoti @composergreg @synths definitely saves time and a mess of wires. I really would like to add some normalled connections for my system 100m tribute, at least mimicking the original Roland CV and gate routing and the like.

I have to say that my modulars are prettier though 😁

@forestine would that be considered small?

I call it System 100m micro 190.5 (halfway between a Roland 190 and 191J). 4 modules, complete synth. #Roland #system100m #behringer #diy #moog #skiff

72hp worth of eurorack modules in 70hp skiff. VCO-VCF-VCA, envelopes and lfo, ring mod,lfo and s&h, Eq, mixer. Portable external speaker.

according to this little brochure, the book "The Synthesizer" (box set) was only $16, basically $4 per book, the same as what Roland charged for, say, their BOSS or Keyboard sales catalog! (In 1987)

"The synthesizer" 4 volume box set of books covering analog synthesis, using the Roland System 100m, but apply to most modular synths with a typical set of modules, including #eurorack or in some cases, semi-modular.

Long out of print, even the second edition, somebody needs to reissue this.

Same, but zoomed out a bit showing the whole #synth. Frame is made of red oak, stained. So much space, I even have an envelope with documentation on all components and all modifications I made (envelope sitting on top of the #modular #synthesizer in the picture). #synthdiy #music #electronica #Hammond #reverb #system100m #Roland #behringer #eurorack

Inside detail of my eurorack System 100m 191J replica. To organize the wiring, I use Velcro straps (in yellow) and some plastic clips I made that are bolted to the back of the vector rail.
