I've got a question about the pss-270 too;
I attempted the data cut mod, and i fucked it up. I soldered and re-soldered and did it all over again. I'm assuming now every pin on the CPU / Synthesizer chip is soldered to either another pin or somewhere else it shouldn't be.
The machine is impossible to use in "normal" operation.
I don't need to turn the switches on or off to get strange patches. i get a paranoid mess each and every time.
When in drum pattern mode, my machine spits a never ending stream of noise, static, giltches, and the occasional melody. At times, it's a drone machine. Other times it's silent. Other times still, the pss-270 will produce wonderful and strange melodies.
The best bit is, that in demonstration mode, it changes to a new random patch at the start of every measure. So if you find a sound you like, you press "stop", and the last patch in memory is still there for you to use/abuse/sample.
So my question is this: Does anyone know what the fuck i did? It's amazing, and i'd like to try do it again.
PS: Jing; I don't know what any of that tablehooters stuff means but if picking up "EM noise" and thus causing "random results" is what my machine is doing, i highly recommend it.
