- Replacing audio peaks by drums: I've written a small tool, drumreplacer, which does this for a single audio channel. However it is rather limited and uses a lot of CPU. Still a far cry from the capabilities of drumagog.

You should check out Aubio http://aubio.piem.org/ It does what you want, and more. It turns my guitar into a midi instrument when combined with jack configured to ultralow latency via my beautiful M-auio 44 soundcard.
