Hi, I am trying a very simple setup on a laptop (MacBook Air running 10.7). I have installed the softsynth ZynAddSubFX (the newest release has brought back OSX support) and connected it to the system audio output using Jack Audio. I can control the synth from the laptop keyboard, and I hear it fine through my monitors, via an Apogee Duet audio interface. The problem is in connecting via midi. My external keyboard that I want to use to control the softsynth is routed through an Mbox2. In OSX's AudioMidi setup, I can see the Mbox2 as an available midi device, but I cannot see ZynAddSubFX to connect it. In the MIDI tab of Jack Audio's "connections" window, I can see ZynAddSubFX as a writable client, but the Mbox 2 (nor anything else) doesn't appear in the "readable clients" pane. So I have no way to connect the two. Could anyone help me to troubleshoot this? My external keyboard is connected to the Mbox2 correctly but there are no indicator lights when I press the keys--should there be? It's been a long time since I used that unit.
