Wow, great device! The intuitive and wonderful looking UI really make it a joy to work with!
Depending on the directions you might want to continue developing this device, I have some patches/devices that might be interesting to you.
I’ve made a couple of devices in the past that are in some ways similar — storing and recalling snapshots of parameter values in Live — but focussed more on placing the preset-snapshots in a 2 or 3-dimensional space and then smoothly interpolating between them, using Mira or Roli block as input —though you could also use a trackpad or even a simple pictslider.
If you think you might be interested in developing your device in that direction, I’d be more than happy to share my stuff with you (for inspiration and/or re-use of parts of the patcher logic). Everything works flawlessly, but the look and feel aren’t nearly as nice and clean as what you’ve made, and I don’t really have the time to get it to that level.
