I am setting up a system and was curious if LP2 can see both the SoundGrid driver channels (inserts from a LV1) AND an external soundcard for AES card for additional IO (insert on a Mon Controller)? Or do I run two instances of LV2? Can I?
This is a bit tricky at the moment.
Running two instances at once is not supported at the moment, as there is only one set of files that store all audio and application settings.
If you are on a mac you could try to run them as an aggregated device.
I have not tried it but, worth a shot: https://support.apple.com/en-us/HT202000
