Thanks for your video tutorials on how to pair a MOX6 with the PA5X. I did some similar tests with the Korg Wavestate Native in a touchscreen laptop and I'm thinking about buying a Wavestate-M (Module) to get the "hardware feel".
I already had a MODX6 and it has many excellent sounds, but I didn't like its keybed and ended up selling it. Also, since I play sitting down, a second keyboard would be placed too high and would be uncomfortable to play, in my opinion, so I think a module would be more suitable.
The PA5X has plenty of sounds, and many more can be added, but pairing it with another synth-style sound engine can expand its possibilities.
