>> Hi - I think that Chuck's Midi methods seem not to be working (except for very simple examples), as Chuck is dropping Midi events - I'm using the pre-compiled version of Chuck 1.3.0 (gidora), on a Mac Mini (2.7GHz I7), with OSX 10.7.5 (Lion).

>> The only type of ON/OFF sequence in which Chuck seems not to "swallow" any notes is of the form Note1 ON, Note1 OFF, Note2 ON, Note2 OFF…  Instead, I'm generating Midi streams in which there are new note On events before the prior note goes off. They happen when I play legato with a Yamaha WX5 wind controller, but any Midi keyboard would also generate such sequences if one presses a new key before releasing another one that is already sounding.

>> Capturing the same with Chuck only shows the 1st Note ON (and all the CCs, which are correct), but the rest of the Note ONs/OFFs vanish (BTW, playing very slowly makes no difference). To make sure it was not some bug in my code, I captured the Midi using just Chuck's example in miniAudicle->File->Open Example->MIDI->gomidi (the numeric output is converted below, just for readability):

>> Only by fully ending each note before playing the succeeding one, all the Note ONs/OFFs show up. But that's not useable...
