thnx again Zam, guess its worth trying! There are special line level audio switching  delays, see this thread https://www.gearslutz.com/board/geekslutz-forum/655766-how-choose-relay-audio-switching.html

Might be good fun to put some in my SEQ-in-progress..

I try it, for low internal level, mixing desk, mute function, usable for mix/repro operation, but not for automation at mixdown. I don't valid this after evaluation. So it's simple, if it's for monitor or "off" record function relay are fine and easy

Best

Hello EsotericLabs!

Actually you don't even need DOUT, I'm driving relay modules right from J10B pins on my CORE_STM32F4. These relay modules are really cheap, 1 euro from AliExpress, have LED indicator, powered by 5V, draw <70ma in ON state, can switch up to 10A at 230V (yep, how about MIDIfying your coffee machine? ;) ) but the relay have only SPDT contact group, means you need 2 relay modules to switch stereo signal.

For switching audio signals I'd also consider using 4051/4052/4053 analog multiplexer ICs dependig on the audio routing configuration needed, or Vishay DG201/408/409 for higher voltages found in modular synths.
