Steps I did (accidentally) 1. Created couple of groups 2. Added notes to sequencer 3. Create another group for AUTOMATION 4. Router groups from point 1) to sound banks in AUTOMATION group (every sound bank had its own GATE) 5. Sound export Effect: sound peeks etc. 6. Export one more time. Song name is incremented by 1 automatically Effect: sound peeks etc. 7. Export one more time. Song name changed by me. Effect: OK. No more peeks etc. There are many bugs in Maschine that happens on occasion and I'm not able to reproduce them but they can be easily fixed by doing some another action. However this reported bug happend to me the second time.
