Live Workflow Tools has released Clip Gain for Ableton Live 11, a Max for Live device that allows you to control the gain of individual clips in your Live Set via key commands.
You can assign individual keys for increase and decrease of clip gain and assign the step size (in dB) that gets changed per key press.
Simply add the device to your session, assign the keycommands (ctrl + k) or midi (ctrl + m) to the “Increase” and “Decrease” buttons and start using the device.
Clip Gain is available for purchase for $2 USD.
