I’ve looked in the manual, read previous similar questions (all from 2020 for some reason) and looked on YouTube and I’m still having trouble with this.
I’d like to have my main instance be the guitar amps (using a global rackspace) and the 2nd instance to contain the Midi GT 2 plugins and sounds. With this set up I was hoping to reduce the CPU load on the Main Instance to make it more stable (it might hang or crash at times).
However I have not been able to find a way to map my one midi controller (Ampero Control) to the 2nd instance to simultaneously switch variations/songs on both instances.
I have the latest Windows 11 using an Audient ID4 (first version) interface with an i7-12700H processor and 40g RAM.
That’s my approach. Same exact use case BTW. Main guitar sounds in 1st instance and MG2 in second. I just control widgets in 1st instance that control widgets in 2nd instance via the built-in OSC. Works great and it does reduce CPU load.
If the two instances have no need to communicate with each other, in other words, all you want is for commands from the controller to be sent to both instances for handling, and assuming your midi controller (Ampero Control) (which I know nothing about) brings signals into the instance via a MIDI in block, then you just need to add a MIDI in block in each instance for that device.
If you have the same songs in each instance in the same order, then you can “learn” the same control in each instance to move next.
I did something similar when I was using multiple instances. In my case, every instance had the same songs with exactly the same names. Then I used scripting to send messages from the primary instance to each sub-instance to switch to the same song. I found out how to do that on this forum. The link provided by @Vindes is probably where I got it.
