hey dender!

well it fas firstly totally out of tune, and that pitch knob on the back didn't help. secondly it drifted ALOT all the time.

i fixed the tune by detuning the oscilators direcly from the circuit board. quite time concuming but it worked. the drifting on the other hand was because of one ribbon cable connecting the upper left circuit board with the power unit.

one thing that i noticed it that when i detuned the oscilators..
if you want the mod wheel to work correctly for vibrato ect, you have to have the tuning pot in the back of the synth fully left. otherwise the mod wheel only "vibrates" in one direction.

there are quite a few screws on the circuitboard that affected many things. mainly pitch and filter ect. i might have to experiment some more.

if anyone knows where i could get a new ribbon cable (i think it only has 5 pins or so, i can take a photo!) let me know. it works for now but i did not replace the cable, i just bent it a bit and turned it back in upside down.

those extra parameters i accessed by pressing the address button, and just choosing value 65 for midi channel or 64 for omni on/off. 
i don't know if this works in the older bit one models. i still would like to know what 63 and 62 do. both are "on/off" values (0 or 1)..

cheers
