Multi-channel (i.e. 4+) buffer~, play~, and groove~???


    Apr 26 2006 | 7:04 pm
    Has anybody come across (or made) a [buffer~]-like object which accommodates more than four channels? And/or playback objects to match? I need it to work with eight for my current project (though more would be useful for future reference).
    Of course, if I could choose which of the source channels to load into a normal [buffer~] (e.g. 1, 2, 3, 4 into one and 5, 6, 7, 8 into another), that would work fine -- I can sync the output using [play~], for example. But I'm pretty sure (from my explorations at least) that that's not possible. Can anyone suggest a workaround?
    I'd be very grateful for thoughts. Many thanks.

      Hi Pete,
      I was asking for this a while ago too. I believe at the time it was proposed to add a channel offeset message (so load 4 channels starting with the 5th), which would work in all cases where you wanted to work with consecutive channels. But there is no sign of this in the documentation, so I guess it was not implemented. It looks like at this point you just have to split or otherwise prepare your soundfiles ahead of time.
      In general, the ability to access any channels of a multichannel file with both buffer~ and sfplay~ would be very useful.

      Hi,
      As for me, the methode i use in this case is as follows : 1- i use sfplay~ to play the sound in any number of channels i need and the speed message to sfplay~ (something like speed 7 is cool). 2- with poke~ i record the channel i want from sfplay~to the channel i want in buffer~. (that means you have to name your buffers... as usual you'll tell me...) 3- I use as many buffer~ as i need to. ***the "file position" output of sfplay~ commands poke~ and it works very fine... ***all those buffers together make one BIG buffer~...
      Maybe it helps... i hope so... Cheers.
      ps : hi benjamin ! so how's seattle so far ? don't you miss IRCAM ? :-) I have great memories of the max-msp courses at ircam with you and also Acanthes with Harvey :-) I hope everything is fine. Good luck for everything and also thanks for everything.

      This might well work for me. And even if it doesn't, it's already suggested a solution to a different problem I had!
      Many thanks to all for your suggestions/responses.
