Thank you thats really helpful. So for stereo pads, it may make more sense to send them out as mono and then just use stereo effects in the DAW to make them bigger again. I have no problem with mono. It also means I can run stuff through my MMF filter which I am quite fond of.
I decided Maths actually makes the most sense. I see small builds with Pams, Maths and a Morphagene. This allows me to also keep my BIA in the case as well. I am interested in how I can modulate the BIA with Maths, but also get it to trigger from the MG when I use them together. I could get some cool layered sounds that way.
Also I have room for a 1u Sloth, so I got that too. A slow 15-20 second LFO could really be cool with the MG and BIA.
This could be a quite powerful build once I get a good grasp on it.
