Adjusting the Gain with a midi controller

[radio42]

The volume of an input mixer channel is actually controlled by its fader. The gain is on top - but both attenuate/amplify the volume of the recorded source. Note, that digital audio has no headroom.

The fader range is from -unlimited dB (-999, fader down) to 0 dB (fader up).
The gain ranges from -15 dB to +15 dB.

Commands you can use are for example:
MIXER_OUTPUT_VOLUME_SET
MIXER_INPUT_VOLUME_CHANGE
MIXER_INPUT_GAIN_SET

Macros you can use are for example:
${mididata2asvol}
${mididata2aspan}
${mididata2asgain}

See the user manual appendix for more details.
