If I understand what you're asking for, then I know I've seen exactly this. I most likely saw it at... Tucows http://linux.tucows.com/ Or Freshmeat http://freshmeat.net/ I remember it saying that you can (for instance) sing into a mic and the notes would be imputted into a midi file. I wish I could point you to something more definate. I hope this helps. Rocco
