hello
I am french, sorry for my bad english...
I bought today this synth for 8€, I have never done circuit-bending. but on this little keyboard, I would like to add some functions (effects on the sound and/or effects on the rythm (it has nice sounding drum sounds inside!)).
I opened the keyboard, and searched according to the chips references I saw, but most of them gives me no result in google...
ref | name written on the pcb | type |
YAMAHA YM 3419B | "RYP7" | SMD |
YAMAHA YM 3420B | "OPU" | SMD |
A203 87E25 XE415A0 | "Gate Array" | SMD |
YAMAHA XF305D0 | 2M ROM | DIL |
8831EX XE402AO-611 | 1M ROM | DIL |
TOSHIBA TC5565APL-12 | 64k RAM | DIL |
I can give photos if you want.
I don't know what is the FM IC and Rythm IC... I mean the 1st and 2nd, but i'm not sure.
Is there someone who has already bent this keyboard could give me some info about what I can do on this keyboard ?
I'd like to modify the drum sounds
