I recently picked up a Studio Electronics Boomstar 3003. Man it sounds great! I can record MIDI & audio with it into Logic Pro X via MIDI Out cable connector on my USB keyboard controller without a problem, however can't figure out how to playback the recorded MIDI track to generate sound from the external synth. Doing so with my USB external synths works fine but the Boomstar only has MIDI connections. Just trying to hit play on Logic and have pre-recorded MIDI data on External MIDI track (with plugin activated) play the Boomstar. Can't figure out why it's not working when I'm able to play and record it live with no problem. Basically the MIDI data isn't getting to the Boomstar from Logic Pro X, even though the keyboard controller is connected via USB and the synth is connected to the MIDI out of that controller. Any help is much appreciated!!!
