Yamaha PSS series keyboards.

Which model numbers are best to bend or are they all essentially the same?

i've got a pss-6. it bends! ;D
the weirdest bend i found on it was a short which is connected to a light dependant resistor. when there's enough light it kicks off playing a sequence of fast and randomly timed/pitched notes with whatever voice is playing at that time. sounds amazing with some of the patches. looking at it now i reckon a toggle switch might have been a better choice. hmmm. ......getting twitchy with my screwdriver again...
also found a great buzzing distortion and equipped the case with body contact which adds a lowend honk.
i'll try and get round to opening the keyboard up again later and describe some more details of the bends. i've been meaning to give the little pss another tweakage for a while now.

hadn't quite woken up when i wrote the last reply...
so, here's some more pss info. these are all bendable:
pss-6 -- oddball wavetable synth. good sound quality, weird bends.
pss-80 -- it's a digital squarewave keyboard. love the 'c64' type sound.
pss-100 -- similar type of synth to the pss-80.
pss-140 -- fm synth. great bends by adding 8 toggle switches to cut the datastream between the cpu and fm chip. let the tuned drones begin!
pss-270 -- it's the same synth as the 140 with a chorus effect built in and stereo speakers. it's a nice chorus though. :D
140/270 fm mod : http://circuit-bent.net/pss-270-tutorial.html
there must be lots more!

Hi - I have the PSS-12 which I think is the stereo version of the PSS-6. Good sound quality but I didn't find many exciting bends, just a few bends that alter some of the voices.
I have a pss-480 and 580 which seem almost identicle bar a slightly different case. Both have fm editing capabilities, and a seperate PCM rhythm chip that can really easily be bent to make a variety of noisey distorted/flanging drums. Both have midi too. If you can get one cheap they are easy to bend and they even have an audio out too so you don't even have to bother installing a line out!
Most of the higher number pss are fm, but a couple such as pss-790 are 'awm' synthesis and I hear they are quite fun to bend too. There are definately loads of pss's out there.
I think there a pss-570 which is one up from the pss-470 which i wouldn't mind getting my hands on. I saw one around christmas time but I didn't have the money or space to accomidate any more of what my girlfriend calls 'clutter' ;)
