Hi I'm trying to send program change messages from chuck, but fail. I've been looking at stuff like this: https://lists.cs.princeton.edu/pipermail/chuck-users/2007-January/001426.htm... http://www.rattus.net/~packrat/audio/ChucK/files/midisender.ck Using the first URL (a post from Kassen), I try this: 192 => midimessage.data1; 3 => midimessage.data2; bcrMidiOut.send(midimessage); But get "[chuck](via RtMidi): RtMidiOut::sendMessage: event parsing error!". Note: I can send 3 byte messages on the port without problems, I'm thinking it's the 2 byte nature of program change that I doesn't handle correctly. I'm not too much into the deeper working of neither midi messages or what chuck does, so if someone could point me in the right direction, I'd be thankful! -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
