New to Max MSP – no sound.

New to Max MSP – no sound.

Hi everyone. I’m building a sampler for a project, and I can’t get any sound from Max MSP. Everything is patched fine, audio is on in the DSP settings (I’ve tried making the output my macbook pro built-in output and my mbox2 Mini with no luck for either), the ezdac is on, but no sound. I’ve tried an oscillator in audiotester and got nothing, I’m not sure if you’re supposed to see a wave in the audiotester when the oscillator is on, but I didn’t. I sent the patch and samples to a friend and it works fine for him, so I have absolutely no idea why I can’t get any sound. I’m running the patch in Max5, and downloaded the Demo of Max6 to see if that solved the problem, but still no luck. If anyone could shed any light on the situation it would be very much appreciated.

Specs, if needed:
Macbook Pro (2009)
2.8 GHz Intel Core 2 Duo
500GB Hard Drive
Mac OSX 10.7.2

Thanks in advance,

have you tried to follow any of the simple the built-in MSP tutorials and see if these work?

Just tried a tutorial and got sound… I’m confused. I have no idea why my patch, with no alterations at all, works for a friend, but not for me.

just try step by step, reduce it to its bare minimum (remove patch cords) and see what can cause the problem.
start from scratch, copy parts of it, slowly build up…

post your patch

Here’s the patch: I’ve done it as a zip to include the samples as well.

While looking into this, I ended up significantly refactoring your patch.

First, save this as Sounder.maxpat:

– Pasted Max Patch, click to expand. –

Next, here’s your top level patch, edited to use the Sounder abstraction:

i just tested it. I only got sound by pressing the C1 note.
All the others don’t produce any probably due to a typo:
if you double click the p Sound2 object while the patch is locked, you will see the patch within. there the filenames of the sampler wav files are mentioned – however they miss the file extension .wav as in the p Sound1 patch.

so it maybe a typo in all those except C1 that is causing you the headache.
try it and let us know…

zigzag – Yeah, you were right, it was a typo in the sub-patches. It’s playing now, but the quality of the playback is pretty sketchy, so I think I need to do some work on the buffer lengths. Thanks for your help.

Chris Muir- Thanks, this patch is working perfectly.
