Hi'
Is it me or does the drumstation have a problem with fast midi signals.. for example a fast snare build-up???

I'm using the old tracker Fasttrack as a sequenzer, could that be the reason?

Are you using your drumstation from a midi thru of another device?

I've got a BassStation Rack and I know that if I don't put it first in a midi chain, it plays havoc with the timing.
