How do you unpack a multichannel sample with mc.groove so that it is true stereo?
I'm a newbie and haven't been able to figure this out. I have a multichannel groove, and when I try to unpack it so that I can get each L and R for the first channel, it comes out mono in the end. I am definitely using a stereo sample that pans hard left and right.
patcher:

it's a bit confusing because 'groove~' still uses its regular arguments to determine whether it will output mono or multichannel. so you need one extra argument after the buffer name for the number of channels available at its outputs... and this, underneath its 'multichannel output' in the MC-world... hope that makes sense, here's a little extra to help understand how you might work processing with MC-objects thinking before and after the signal chain of groove~ itself:

Thanks for the in-depth explanation! I'm still trying to understand, but I get it a lot more. I have an mc.gain slider instead of live.gain in my project, and I found that if I connected two of those I basically had what I want.
Left and right here seem to work equivalently with hard left/right retained.

ok, i think i see what you want in your pic, but it seems like it could be the same as this:

there are regular versions of MSP objects and MC versions(maybe you already know, but just being thorough, to get a clearcut path of learning through MSP, it's best to start with these tutorials and go in order: https://docs.cycling74.com/max8/tutorials/00_mspindex )
if you find yourself converting from blue(MC) patch-chords/cables, to yellow(regular-MSP), back to blue(MC) patch-chords again, without any additional DSP-processing in between each of those conversions, chances are you might not need to work with MC objects at all.
but maybe you have a longer-term plan i'm not seeing here, no worries if so, seems like you're figuring it out, just trying to make sure you're aware of the nuances to these different parts of the overall Max environment. hope it can help 🍻
Thank you for that link to the tutorials. I definitely need to go through all that.
