Hi, This is probably simple, but I'm stumped nonetheless. I've set up a Logic file to accept MIDI from a Max/MSP patch, using a Physical Input, and then a Channel Splitter in the Environment. It works fine--I have several instruments in Logic being triggered by MIDI coming from Max, each on a different MIDI channel--no prob there. However, when I try to record it, the MIDI won't record. Even when everything is playing along just fine, Logic shows no incoming MIDI in the Transport. In fact, even if I just use say the Qwerty keyboard to play one of the instruments, it plays just fine, but again, no MIDI will record and Logic shows no incoming MIDI. I can't figure it out. As soon as I set up that Physical Input in the Environment, Logic shows no MIDI coming in on the Transport, yet MIDI IS coming in, and the instruments are being triggered. I know I'm missing something simple, but....HELP! I'm on Logic 9.1.3. I'm attaching a screen shot of a simple version of the file so you can see how I have the Environment set up, etc. Any advice greatly appreciated!
