I’m having an issue with voices on A4.
Track 1 has a drone type patch I made, tracks 3 & 4 have presets from the +drive, and track 2 is muted. The problem is that if I mute track 1 then track 4 gradually fades to a much lower level.
Does anyone know what could be happening? Im still getting to grips with the A4 so I could just be overlooking something that seems obvious to more experienced users! 
Hey, thanks for the reply! I thought I had already checked poly config but it won’t hurt to check it again tomorrow.
This isn’t a case of voice stealing though, the track 4 sound drops in volume when track 1 isn’t playing.
Maybe track 4 has neighbor instead of oscillator. You said it is sound from +drive so it’s possible.
Also a good idea to check for! Thanks 
The sound on track 1 definitely uses a neighbour setting, I wonder if that’s the problem. I’ll test it out a bit later…
Ok it was definitely the poly config settings! Thanks for the input guys!
