I have a feeling that this will become a stupid question. But I haven't found the answer yet so what ever.

I have made a 4 operator FM patch. When put it inside the [poly~], it can only produce one sound at any given moment.

I suspect it's due to that I use [send~] and [receive~] in the [4opFMsub] subpatch (They are strictly inside the subpatch). However, from what I searched in the form, the problem should be solved in Max 6.0.4 (I use 6.0.7). Also I tried the same patch in Max 5 and the result is the same.

I attached the whole patch. You can load sound preset by click the read button inside the [4opFMsub] patch, and load either json file in the patches/ folder.

Still haven't figure it out. Anyone can suggest some possible cause?

Well, this is so strange. To find the root of the problem, I made a very simple [poly~] patch very similar to the simple_poly example in MSP tutorial 21, and it dosen't work.

The only difference is that I use a [function] for amplitude envelop while the tutorial example use a message directly. How can that make such a difference?

In the attached image, [testpoly~] works while the [testpoly2~] doesn't.

In your FM patch, as your pattr system is in the voice, you first need to read a preset file and recall a preset in 

, you'll see there is no preset in the second voice, and no sound is generated.

I would rather put the whole pattr system in test4op.maxpat rather than in 4opFMsub.maxpat.

In your FM patch, as your pattr system is in the voice, you first need to read a preset file and recall a preset in each voices you may use. If you send open 2 to the poly~, you'll see there is no preset in the second voice, and no sound is generated.

Now I understand what the problem is ! Thanks!

Why this patch doesn't work under poly~?
