Norns and outboard pedals

Some help needed. I searched the forum but did not find an answer.

How do you go about configuring the Norns mixer if using an external pedal as an effects loop?

As an example, say you want to route the audio from Awake out to a reverb pedal that has it’s own wet/dry mix so you only want Norns to record the return signal from the pedal. How would you set up the mixer to do that? Also, how do you set up the mixer so the HP output is only monitoring the return signal.

I tried a bunch of different approaches and do not seem to be able to eliminate the original output from Awake from the mix.

Thanks.

how do you set up the mixer so the HP output is only monitoring the return signal.

you can’t; the headphone output is not separate from the main output, it is just an extra gain stage. the codec is stereo I/O.

say you want to route the audio from Awake out to a reverb pedal that has it’s own wet/dry mix so you only want Norns to record the return signal from the pedal.

if you mean recording with the TAPE function, you can’t. there are no routing options for the input to TAPE; it just captures the same stereo output as the main and the headphone jacks. (the TAPE utility is intentionally pretty basic. there are a few issues on the table w/r/t a more full-featured recording system, but it’s back-burner ATM.)

if you want to learn a little supercollider, you could either extend one of the core norns classes like Crone or AudioContext, or create a “mixin” for engine classes, such that you can use supercollider to capture the ADC signal using DiskOut.ar(<streamingBuffer>, SoundIn.ar([0, 1]).

Thanks @zebra that clears things up.
