I'm trying to create an on-the-go sampling synth that you can record samples in that you can immediately play back. I'm having a very difficult time getting it to be polyphonic. I did something similar to this in the past that I got to work and I've been comparing the two and copy/pasting all over but still seem to have a lot of problems. I stripped this down to make it easier to find the problem. Playback works fine, but only a note at a time. Any help/advice would be greatly appreciated.

The information at all inlets is sent to the voice you set it to, using the target message. In this case, if global information needs to be sent to all voices, then it would be easier to use send and receive.

Thanks for your help. I cleaned it up using send/receive and moved the waveform~ to a more appropriate position. Although it looks much cleaner now, it is still not polyphonic. I need some sort of way of incorporating thispoly~. That's what I just can't seem to get working.

Here's a basic example of the logic you'd use with thispoly~. As you might expect, it's set up to work with the "note" message to the poly~ object. Given the structure of your patch, this should help to set you straight. The example uses something a lot simpler than your sampler patch, but I figure you can suss it out nonetheless.

Thank you Gregory. I had tried a setup similar to this (that is very similar to the one in the tutorial for poly~). My issue with this one however is the line~. The duration of the sample being played is set by the duration of the recorded sample which is being looped as long as you're holding down a note. So I would need to send that "turn me off when you're done" whenever velocity=0. I tried to send a bang to the "mute 1, 0" message whenever velocity was = to 0, but couldn't get that working right either.

I hope that made sense...


Have you considered the adsr~ object as a line~ replacement? It's quite poly~ friendly (check the "polysynth" subpatch in the adsr~ helpfile)....

That may work! I didn't even think about that. I'll check it out when I get some time to work on it and get back to you.

Thanks so much!
