How to remove certain package from debian?

A

Q

How to optimize my system for audio/midi?

A

For some uses, it can be helpful to run a realtime (RT) kernel, but generally, this isn't necessary anymore.
In Linux kernels, 3.0 and later, many of the additionally required realtime patches have been incorporated as standard. For those who are recording Audio, a standard non-realtime kernel may be sufficient for your needs, and running Jack with a non realtime kernel will work fine.

Q

How to eliminate noise from live production?

A

Live noise has many causes, including ground-loops, and other equipment near and far injecting static of many kinds. This includes including weak but audio-active USB signals, PC fan noise, firewire, et cetera, into powerline, ground, and thence into the system.
