Hi there, I'm new to Max and to the forums and have a question.

I have the simplest polyphonic Max instrument with a single oscillator, when I replace mtof with a coll object to read from a tuning file, it stops playing notes polyphonically. What do I need to do to enable this?

Unless we can see your patch, this will be a game of "20 questions."

Open your patch, choose all of its contents, choose

Understood, thank-you for your response and guidance.

Here is the patch, inside the poly object I have left the mtof wired up to show the poly sounds working, with the alternative of the coll object to the right. As soon as mtof is replaced with coll and a .txt tuning file is loaded into the read box, it does indeed alter the frequencies according to the tuning file but it does not play them polyphonically, I would like to know what I need to do to make this happen. If I hold more than one key down it reverts back to the standard tuning (still polyphonically).

I did save a tuning file into the read box before I saved and pasted the patch so I hope it is still there for you to see.

As I mentioned I am at novice level and I very much appreciate your time.

 the abstraction you've loaded. You'll need to send the contents of musub.maxpat

Actually, we'd need to see what's inside the abstraction you've loaded. You'll need to send the contents of musub.maxpat

Apologies, here is the contents of musub.maxpat

Umm... You're never going to get anything other than standard tuning frequencies out of the 

 because it's not hooked up to anything, and - at least on what you posted here - the 

 object is receiving values in the range 0 - 127 (they're MIDI note numbers), and converting them. If you want to do anything other than standard tunings, you'd need to 

 object with the same indices (0 - 127), followed by the frequency in Hz. you want for all 128 entries (e.g. one

If you want to do anything other than standard tunings, you'd need to replace the mtof object with a coll object with the same indices (0 - 127), followed by the frequency in Hz. you want for all 128 entries (e.g. one <note number>, <frequency>; entry for each MIDI key). And you ought to select the coll, open its Inspector, and check Save Data With Patcher, since you'll want the stuff you put into the coll to stick around.

Yes I had left the mtof object in place just to show the poly working before the coll replaced it, and I was dubious as to whether the tuning file would still be inside it after I had pasted the patch here... but after checking the 

it now plays polyphonically according to the tuning file..excellent!. I guess this box needs to be checked even for the main patch to read what's inside the coll of the poly object. What is strange is that the main patch was reading the tuning file from coll even without this box being checked but it was not playing polyphonically, but it doesn't matter anymore, checking the box has changed everything.
