I am running multiple instances of MG3 in Gig Performer, one for each instrument in my studio. Unfortunately it seems that the Input Gain and Gate settings do not save into the Patch save state, nor do they save into the DAW state. Instead it seems to be saving to the data folder on the device, such that if I adjust them for one MG3 instance, all the others match that value on reboot, similar to how it works for the UI settings (flat vs default). Is this how it is supposed to work or is something messed up in my setup?
It works as designed and there is a logic behind it, gate depends on the instrument not the preset but just like you, I wish it would save in the preset.
I have asked for this in the past, maybe if more players will ask for it… the developer might change it.
