Rakarrack
By Sonic Ladder
Rakarrack is a Linux-oriented guitar multi-effects application with a rack of processing options. It is useful for live instrument chains and experimenting with combinations of distortion, modulation and ambience. Audio-server routing is part of setup. Check the maintained project and distribution package so the selected build matches the Linux system and audio environment in use.
For direct recording, check interface input gain and monitoring latency before evaluating the sound. A pedal or amplifier processor may still need separate cabinet processing, depending on the signal chain.
