Emax

Thanks for the quick reply. 
Can I fix or get those diods fixed somehow? 
It's not a big deal since I have a MIDI keyboard to control it with. 

The display doesn't cause any noise now since it's not working =) 
I guess that the inverter is broken but I will check with a multimeter tonight.

I guess I go for the VFD then. =)

Great Jammie. Where do I send the board? 

Regards
Kalle

A funny thing is that on some sounds (loaded from disk), the D and Eb (5:th octave) generate sound but the voices "hangs" In most other sound banks they're dead as the other ones. It seems that only sounds with long decay, sustain and/or release are generated from the 5:th octave D and Eb.
