Any reason you don’t go for an ES-9?
-- Praveen

I have 104HP available in the Caixa, and the ES-9 takes up 16hp, a full 15% of the available space. It's also redundant with the Caixa built-in outputs, I don't need the extra 1/4" main outs or the headphone jack.

The ES-8 only takes 8hp. I'm also thinking about the Befaco AC/DC which only takes up 6hp (albeit with 4 outs instead of 8). I'm still looking for other module options, so I can 1. integrate with VCV Rack as an add'l modulation source, and 2. record multiple lanes at once into Ableton Live.

If I keep expanding (let's face it, I probably will), and get a more permanent case in the studio, then the ES-9 would be perfect there as I'll have a lot more room.
