Gutenmorgen Bucius,

Welcome on this very nice forum.
I myself own the SD1 and can't detect what your REAL problem is :
a. Your SD1 does not send MIDI-data ?
b. Your PC does not receive MIDI data ?
c. The sounds sound messed up ?
d. .....

Please be more specific in explaining.
(If you like, in German to my personal email-box )

Important setings on the SD1 are the MIDI-transmit channels.

The SD1 has two MIDI-in :
The General MIDI one-, and the Ketron-one that is specially suited for Ketron/SOlton sysex-commands/programchanges etc.

I think for you, the best choice is the Ketron input.

What sequencer do you use ?

Since I own the SD1 I hardly use MIDI anymore but the SD1 is absolutely capable to do whatever you want.
