only left channel records (and quietly), record groove buffer wave

Apr 13 2012 | 1:14 am

I can find no thread, and my teacher and I are stumped. Please Help! When I record using a stereo record~ into a stereo buffer~ groove~ and wave~ the resulting recording only plays through the left speaker (and quietly). Note: I am using max5

Change your arguments for Buffer One to something like [Buffer~ One 2000 2].
First number is duration, second is number of channels.
(why did you have -1?)
Patcher below should have the changes and should work. But if not, try what I’ve described above.

That didn’t seem to fix it. Any one else take a stab at this?

It’s a little unclear by your patch. Are the source files you are loading into the buffer at the beginning mono or stereo?

everything seems to work fine here. Make sure to have both your buffers with 2 channels (eg [buffer~ one 2000 2] and [buffer~ two 2000 2], maybe your -1 was causing the bugs, maybe not) and also, make sure your source file has 2 channels to be recorded in the 2d buffer.

(in case it helps… here is how i used your patch)

(but didn’t change much really, apart from the -1 in the buffers – also replaced the "name" by "set" in the messages [name one 1] and [name two 1] going to waveform~, because "name" refers to a soundfile, whereas "set" does refer to a buffer name, which seems more appropriate here)

I figured out my problem. I was loading in mono files of silence to resize my wave~ to ready it to be record into. I just recorded some fresh samples of silence in stereo and its working fine now. Another one of those DUH! moments. If you know a way to resize the wave~ window in real time as recording, that would be handy tip. Thanks again for all of your help.
