There is a strange issue with my voice card 1 on channel 1. After turning the synth on it is completely mute. But after a warmup and some gymnastics ( adjusting filters, turning osc´s on and off etc.) it slowly comes back. First as a cutting noise and then as a full working voice. It is like that every time.
I think it´s not related with osc´s and filters. It´s more like an amplification problem. What could I check?
