Adjusting the Gain with a midi controller

[nguoivohinh]

As mentioned in previous post I have a Korg NanoKontrol2 midi controller. I have a number of the sliders and buttons configure for certain actions.

I have been playing around with trying to control my MIC gain with the knob control instead of a slider but I am not sure if I got right or not. I tried the Macro as well just some simple commands but it goes full to one side only.

I want to get to a position where I can gradually increase or decrease the gain with the Midi controller. Is this possible?

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.

In your case it might be: MIXER_INPUT_GAIN_SET command with the ${mididata2asgain} macro which you can use in your MIDI mapping.
E.g.
MIXER_INPUT_GAIN_SET MIC|${mididata2asgain}
