This tiny synth/sequencer’s biggest claim to fame was it’s portability. Basically, it’s got 30 pre-GM instruments and one drum kit with 26 sounds, some of which aren’t all that bad. It’s sequencer is handy too. You can read more about this “walkstation” here.
I thought I’d open it up and see what I can see. After poking around for a bit, it was clear that many interesting features are hibernating on this little device. Here it is jacked up on my workbench, many wires for the bends are already in place. I used an experimenters board for wire management: On IC4, pins 27-36, and 38-53 can be directly connected in any combination (I’ve found so far) without crashing and can also be connected to ground.
Pin 37 can be connected to the above pin numbers, some of the pins will create really cool stacatto notes (short blips). Don’t connect this pin to ground, it will crash. below in forum post #63, arsenlives experienced...
