JackMiniMix

JackMiniMix is a simple mixer for the Jack Audio Connection Kit with an OSC based control interface. It supports a user configurable number of stereo inputs, which can then be queried and controlled by sending it OSC messages. It is released under the GPL license.

OSC Interface

Channels numbers range from 1 to the total number of channels. Gains are in floating point decibels in the range -90 to 90 dB, where -90 dB is treated as infinite.
