There are a couple of options you could try right now: * use the javascript / midi interface in Mixxx to write a fake midi device that can relay information from mixxx to your other software. We don't support clock information, but you could relay midi CC or key events. I have some boilerplate python code that creates a midi device. * Write a USB HID driver to mimic a controller, and again leverage the javascript interface. This is harder, but more accurate. * Create a click track, load it into a sampler, and loop it. This way you'd have a bpm-locked click track that you could feed into gear that can sync to that. I think some hacking might be necessary to create a dedicated output for the sampler, but it would be fairly minimal. * Write midi clock in/out support into our Master Sync code, which is a major project I'm planning to do this coming year :). * Just sync it by ear, since there's a bpm display. The sync will drift depending on the sound card clock, but that's a well-known physical limitation.
Obviously none of these are ideal, and all will take a decent amount of development. Playing back midi tracks is a really hard problem, because what does it sound like when the user scratches the track? For now you'll have to render out the midi to a waveform and then load that.
