[computer at sea]

I had previously suggested the PSS-6 wasn't a super keyboard, but upon opening it back up I've had much better results.  Sending the trigger from a 555 oscillator opens up some new options.  I'll post diagrams tomorrow once I get my notes straightened out, but there's some pretty nice looping capabilities.

Here's the diagram.  The two direct point to point switches are mods discovered by Kaseo, and the rest is new stuff.



The oscillator catches and repeats a sound at a variable rate, and the body contacts when connected (really firmly connected) change the looped sound.  Samples coming soon...

Just checked some of these bends with my PSS-6. The noisy glitch and the very nice glitch don't work. The first one connecting pins 1 and 16 resets the device with a loud pop, nothing more. The second one connecting pins 28 and 29 produces a stable glitch in literally 1 out of 100 tries. The rest of the time it just locks everything up after emitting a 1-2 second glitch sound and you have to switch off and on again.

The only "bend" I've found (the overdrive points i found on another schematic don't work either) is the battery interrupt, which sometimes (1 out of 20) crashes the machine into making strange noises. Quite useless though.

I connected some more points using LEDs but these connections effects are too subtle to be really useful and more or less absolutely crap. I just left them installed in case I send the output through some heavy distortion, then the mods are slighty audible...
