I also just got an H90 (incredible unit!) and am figuring out how to best incorporate it into my QC workflow. Right now, for ease of use and to maintain the stereo functionality of the H90, I am simply using the two mono loops of the QC and using the inserts of the H90 as suggested above.
However, there is a way to separate Preset A and Preset B so that A is mono and B is stereo. You need to put the H90 in Dual Routing Mode with and then set the path to Pre/Post . The signal chain looks like this:
QC Send 1 > H90 Input 1 > H90 Out 1 > QC Input 2 (instead of Return 1)
QC Send 2 > H90 Input 3 > H90 Out 3/4 > QC Return 1/2
On the QC grid you would have Row 2’s input set to hardware Input 2, and presumably have it before your amp block, and Preset B (Return 1/2) after the amp block.
I tried this and it works… but it’s kinda fiddly and makes programming patches on the QC a lot more laborious. I personally favor the freedom of being able to just put the “FX Loop 1/2” block (or the separate mono blocks for before/after amp). It’s a shame they didn’t give us two stereo loops on the QC but it’s totally doable if you’re willing to invest the time.
