if your usb soundcard and speakers are making a high pitched squeel try putting it through a usb hub
- rocksmith usb adapter from an xbox 360 for guitar.
- ableton launchpad – with launchpad-ctrl opensource drivers
- zoom h2
- ableton triggerfinger
- 5.1 digital sound from c106 usb audio
opensource programs worth mentioning
- qjacctl – for managing audio connections
If you are needing something solid and you want to get serious about being a live musician give Ableton Live a try.I would say the workflow is better as an artist than what linux can provide in one application.
