Hi Spkguitar and thanks for your reply. Ok here we go:

I check that in many systems: a) Mac G4 OS X 10.3 Protools TDM 6.2 and Digital Performer 4.5. b) Mac G5 OS X 10.5.8 Protools 8 LE and Digital Performer 7.2. c) IMac 2007 OS X 10.5.8 Protools 8 LE an Digital Performer 7.2. d) IMac late 2012 OS X Yosemite Protools 9 native and Digital Performer 9.

So, there's no problem about the system o software version.

I'm not creating an instrument track (DLS Synth) in DP, I'm using Apple software synth that is recognized with "interaplication MIDI-soft synth on". I'm not using a wrapper, so that I'm assuming DP is working as a rewire program, but my technical question in how PT can automatically identify DP as a rewire software?.

With DP open, PT can see in "predefined MIDI track output" Apple Soft Synth as a destination device for my MIDI information. I think this is fantastic for setup SMF with GM Program Change information files, don't you think?.

Thank you very much in advance for you wellcome opinion!
