The DAWsum MIDI controller from Careful AudioThe ultimate hi-end DAW controller for the discriminating studio cat.
FeaturesThe DAWsum is wireless, plus it has high-quality components and a 70's retro-analog vibe (wood sides, vint-style patch bay, etc).
I am researching how to add features like a headphone/monitor jack (2nd wireless device, same?), electronic patchbay (in base unit), ball controller, gesture controller, wind controller etc.
You can connect your mouse and keyboard to the DAWsum remote (or not), connect the base unit to a Firewire/USB port on your computer or DAW, and off you go.
Emulates the JL Cooper protocol and so it should work perfectly with ProTools 6.9 as well as others. I haven't tested it with 7.0.
Auto-touch faders NOT cheap-feeling (billet aluminum pots and fader knobs) , hi-end with no jittering.
Research:
Investigate Tranzport type technology for remote control (is this only MIDI?)
Or maybe use an existing laptop-type wireless technology (like iTunes iPort?)
How to send audio for headphones?
http://www.radikaltechnologies.com/Products/SAC-2_2/sac-2_2_0.htmlThere will also be additional components which can be connected into the base unit, like an old-school early Moog-like synthesizer with jacks and cables and just a few knobs.
Other potential features:
midi strip controller
gesture controller
breath controller
optical controller
large-scale controller (room-sized)
synth keyboard connection/software/plug-in
personalities for ProTools, plus Reason, Abelton Live, Sonar, etc.
PrototypeThis guy:
http://www.arttec.net/Industrial/Design.html builds prototypes for people. He may also have ideas on how to deal with the patent stuff.
Or I can piece one together from stand-alone components, then find out how to manufacture it all as one unit.
I really like the look of the Jomox products:

LicensingFind out how to get a license to use someone else's technology, specifically for the wireless MIDI component.
Organ Works has produces this Wireless Midi setup:

Uses UHF which is faster than bluetooth. They claim 2ms latency.
They also sell individual MIDI components that might be very useful:

One unique feature of the DAWsum is that the base unit has additional interface features beyond MIDI e.g. USB, FireWire, plus a synthesizer (controllable via MIDI from the DAWsum remote).
