In a setup with superrack on macbook, wavescard in console and reaper as playback/recording.
the channels 25-32 return distorted in the desk through soundgrid. Only these 8 channels and it doesn’t matter if i use them as returns from superrack or playbacks from reaper.
All the sends to reaper and superrack are clean and all the returns except 25-32 are clean.
channel 25-32 distort as in peak the signal with what sounds like distorted audio and more than just the source distorted.
it is not dependent from the number of racks or the number of channels in reaper. in fact it is the same with only superrack and the card in the desk in the setup.
