Brilliant, thanks a lot! That video was great!

One question: You said "midi external clock on" on the SD90. Where can I find this setting? Is it the same as "clock in" or "clock out" ?

Thanks again

Correct - On your SD90, Touch Menu then touch MIDI. At the bottom of the screen, you will see "Clock In" and "Clock Out". They will both be blue in color. If you touch either one they will change to a yellow background indicating they are "on" or "active".

Clock In = The SD90 is waiting for some other MIDI device to send stop/start/tempo information.

Clock Out = The SD90 will send that info to other MIDI devices you have in your setup AND are configured to accept that info.

I am embarressed. As I wrote in the beginning, I had Connected Right/Left Out from the Ketron and into the Genos.... It should of course be into the mixer…..!

So now Things are better. I still got a little delay using my Launch Pad, but I think it is because of the way I play chords. On the Genos I use "Fingering mode: Fingered" I cant find these settings on the SD90 ? Is it under "View-Chord-mode" ? (finger2)

Yes...Fingered 2.
Are you using audio elements in LaunchPad??

It is the same if I am using Piano or Live Guitar.

I will try to explain:

If I play part of a song With this 4 chords:

E (G#-B-E) - G#dim (G#-B-D) - A (A-C#-E) - C#dim (G-C#-E)

On the Genos, this will sound ok. On the SD90, it does not sound ok. Why the difference??

(If I play E - E7 - A - A7, which I Guess is more correct, then both sounds ok)
