If I had an ISHIZENO ONE today, I would like these submodules:
- A clone of the Moog 500 Series Ladder Filter
- Clones of Dave Smith’s DSM01 and DSM02
- Pretty much all the modules from Mutable Instruments
- White Whale, Meadowphysics, and Earthsea from monome
Since all Mutable Instruments are released under CC-BY-SA-3.0, I think that I will start there. Braids would be a great one, since it has 7 knobs and 6 ports. From a faceplate standpoint, it would fit within one submodule. The 4-digit display would need to be replaced by a custom user interface component on the iOS side, but that should not be too much of a problem.
