Roland Tr-505 with mods and bends

YouTube via wotatwaat
"Individaul pitch and volume control added to each voice. Pitch is bypassable. Sequencer glitches which also trigger midi notes (very cool, cheers to squidfanny for info on that one!) 16 point patchbay + 2 3 way mults and four switchable patches. Global pitch bend. Just built, still learning how to use this baby!"

Roland TR-505 + Audiorealism ADM2 Acid

YouTube via twelvebits
"Basic acid house.
A real 505 and a software 303. Chords are Tal U-No 60, a free Roland Juno 60 plug in. The ADM2 is a very nice 303 emulation but cannot escape from sounding software IMO."

circuit bent yamaha pss790 vector synthesizer

"besides the waveforms getting bent within a synth or tone module a synth or tone module's workstation logic can be bent. usually have onboard sequencers, auto accompainments, and other forms of self control that the control logic of them also gets bent in random ways. usually uncommon that a workstation like this will allow glitch control that allows a user to interact with the ongoing data. the player can take over, the self logic of the short circuit can take over, or there can be a mix of the fuzzy logic inbetween the user's and the keyboard's logic. the logic can reconfigure the voice it self and playing responses as well as control the event of sounds in an ongoing dialogue with itself or a user of the instrument."
