Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
REQUEST for MIDI FX App: Shifting the drummer to match the soloist's recording (ignore the click)
A lot of musicians record MIDI Tracks without using the metronome. They might even add
additional tracks by just using the starting atrckc for their "pulse" reference.
I'm curious if a MIDI FX App could be made to align a MIDI Drum app with the notes already
recorded on another Track. I suspect the shifts in MIDI timing would be small. It's just that
trying to dial-in a MIDI Drum track to a 3-10 minute piano solo only works for short stretches before the tracks get out of sync.
Quantizing the original solo track often destroys the original sense of timing in strange ways.
There might be other benefits for some apps that just don't seem to sit well "in the pocket" and such an App might allow the user to set where the drummer sits in the groove. So, many Drum Apps just don't sit well when added after the other tracks have been recorded
and quantizing can mess up some of the subtle details in the drum track.
