Not that I know of; the computer/hardware device would need time to sense your changes in tempo and chords in real time .. then generate something on the fly to match.. which would obviously be behind your actual changes time wise.

Not sure how a device could possibly look ahead to determine your randomness and adjust as it happens.
Someone else may reply with a surprise answer, but nothing I know of can do this.
