I play in a band that has more instruments than players. As a result, we use a sequencer, currently digital performer, to play back MIDI and audio parts while we play live, and the drummer plays to a click. We are somewhat concerned about the mechanical nature of this, our music has some pretty drastic tempo shifts and we don't like the idea of being constrained to doing it the same way every time.
I'm wondering if there is a way, using Abelton Live or any other software that you might be aware of, for a sequencer to interpret our tempo on the fly and adjust the sequence accordingly. The theory is that we would mic part or all of the drumset and the sequencer would use that information to calculate the tempo. I assume this wouldn't be difficult if, say, the drummer was playing the kick on every beat, but it isn't that simple.
In programs like Acid I believe you can import a drum recording and it can figure out the tempo. I want something that does that on the fly and adjusts the sequence to it.
I hope this makes sense. Thanks in advance for any feedback you can provide.
