[PD] VST plugin host

[Vincent Vanbesien (DIEHCO)]

hello,
I did some print before and after the object [pack 0 0]

For the [notein] with m-audio keyRig 49, inputs and outputs are 
coherent. But not for the BCF2000 switches and [ctlin] (anyway it was 
just a testing for the latest).

Finally, the problem seems come from the vst~ that miss some event when 
releasing (note 0) (but also sometimes when pushing). It is easy to 
reproduce pushing only 2 keys. I understand that the VST plugin 
instrument stay in sustain period until receiving again the note 0. I 
tried with different plugins.

My config is windows 10, puredata 0.43.3 and vst~.dll is from this page 
: http://grrrr.org/data/dev/ext/windows/pd/
Should I compile the whole with newest source for puredata ? from cygwin 
or Microsoft Visual C ?
regards,
*Vincent VANBESIEN*
