Hi from Austria!

If you have the TS305:
As far as I read in the schematics the voltages are +15v, -15v, +6v, and ground. But there are also other
schematics that only show +15v, -15v.

For the MIDI interface I recommend Paul Maddox MIDI2SDS interfaces.
I installed the old version of the MIDI2SDS in my Tama Techstar TS305 and it works really fine!
