I started using Max 5, and I think in the old version you would use a "timeline" object for a representation of a piano roll. What object does this in Max 5? and is there any other solid ways of being able to control a polysynth VST?
however, a new pianoroll type object has been made to go with the current [detonate] object, but it has not been made publicly available yet. i have it, and the associated [pianoroll] support object, because it was put in (by accident?) to the 5.1.beta9 release and i kept it from that. it is nice (much nicer than the old max4 one) but is a bit buggy. however, there has been no word from cycling whether or not this will actually ever be released in a forthcoming official capacity.
lucky for me i had live anyway, so the expensive option mr palomba suggested was only a little bit expensive for me (!).
Sorry to be such a tease, but there is a 3rd party working on a timeline, and very promising it looks too, but to my eternal shame I can't remember who it is right now!
Some very tasty screenshots were submitted to the other Max list a few months ago, and when I enquired more recently of the author how it was going, the indication was that the project was still in progress.
I have the details on another machine, but I guess it's not my business to 'out' the author anyway; suffice it to say, you may yet be pleasantly surprised.
I too have yet to be convinced by Live and I miss Pluggo; a working timeline for Max would be a very welcome thing,
this is the things i dont get about max, its been around for like 20 years. and only version 5 had capabilities to undo more than one thing, and they take out the timeline object right as the next version of it would have been decent.
the only good representation of a piano roll i could make so far that would work with a polysynth vst was a matrix grid with a huge 127 value unpack that sends the corresponding note-ons. but its just ridiculous on cpu in order to run properly with the object i made to go along with it so it would look/work like a piano roll.
