PolyGrid VST not working – any other piano rolls?

Hi,

PolyGrid (http://azertopia.free.fr/PolyGrid.html) looks like a useful midi editor with piano roll and pattern sequencer to run as a VST within Max but it isn’t working in vst~. The only window displayed is about 2 pixels wide and menu bar deep and I can’t click in it or move it. The max window gives me the message "PolyGrid has 1 parameter". No response to "pgmnames" or "params" message. Any ideas?

I really would like a decent piano roll to work with and incorporate into my own GUIs. I am trying to build my own with Max but making a decent piano roll patch is such a pain. I’m using seq~ to store the data and lcd to display it but it feels clunky and is taking ages especially translating mouse movement into graphics and it’s not fun… Does anyone have a piano roll with polyphony and arbitrary quantizing and note size?

Fingers crossed,

Don
