Thanks for your ideas and thoughts. But I think I’m trying to put a square peg in a round hole.
The Boomerang looper has to have MIDI clock to be able to sync with drums and bass. If the clock source is BB and the bass and drum MIDI loops were stored on BB, all would sync OK and I could improvise songs (loop on an extended verse, for example). But BB will not “split out” the Bass MIDI and send it through to the bass module. So, that’s a no go. And I find the bass + drum kits to be too restrictive in terms of bass realism, flexibility, and ability to mix volumes independently. IF BB handled MIDI merge properly, then I could split out the bass and then remap the notes using a MIDI Solutions box. Again, a no go.
If clock is sent from an external source (computer or iPad), there is no way to tap BB to sync drums, because BB cannot quantize to a nearest quarter note or whole note. I could, of course send clock and MIDI files (to BB as drum module, and nanobass as bass module) at the same time, but the songs would be locked in with no ability to improvise. A no go.
I am now exploring an interesting set of live performance looper apps for iPad (Loopy Pro, Quantiloop, Group the Loop, etc). These will send clock, and will quantize groups of loops to nearest quarter or whole note, and you can preload them with your own audio files.This would give me more flexibility over drum (Superior Drummer, Moonkits, etc) and bass sounds (I will play my own, or use EZBass). Loops can be grouped for verse, chorus, bridge, etc. I can mix drum and bass levels independently. I can receive countoff via in ear monitors (or BodyBeat). I would have complete flexibility for improvising. Right now I’m working to narrow it down to the best one for workflow, sync, and reliability.
If all works well, I’ll sell my BB, as I really bought it as an experiment to see if it would do what I need. It apparently won’t. Also, I am tired of fighting with BBManager to create my own custom songs and drum sets. Its much too time-consuming. But I don’t consider myself to be a typical BB user. I think BB is a great little tool for those that want to download the canned songs and kits. I also think its also nice for folks who want to play around in the living room, and use as a metronome for practicing. So no hard feelings. Rock on.
