So I've had a few questions on what exactly this next version will have and why it will be better than the previous, so here we go.

Onboard Synth - Like the EWI-USB my first prototype lacked an onboard synthesizer. People enjoy being able to practice anywhere, and to that end I'm adding a modeled analog synthesizer. It will be only one 'patch' but still be result configured for a wide range of sounds. It will be utilizing the DSP-G1 IC, a fairly new design by Jan Ostman from Sweden. More on this synth can be find at https://janostman.wordpress.com/category/dsp-g1/. And an audio sample here: http://dspsynth.eu/files/Gplugpad.mp3

Pressure Sensitive Keys - Underneath each key is a new sensor that allows for pressure to be measured. Techniques like vibrato played on violin, open holed finger slurs, and custom CC (aftertouch, modulation, etc) can all be assigned to these sensors. You can also assign CCs to the lowest fingered key, which allows for simple control that is very intuitive. Each key can be calibrated so that the CC messages are not sent until a specific value is reached. Very cool stuff.

Dedicated Base Unit - Instead of just a serial transceiver attached to a synth, a base unit will have 4 control knobs, and 7 assignable buttons for ease of patch configuration. These controls will be mapped into Reason's Combinator device.

Wooden Construction - As first planned, the instrument will be of wooden construction, not plastic. With a dedicated beautiful veneer specially chosen to make a beautiful instrument. It should look at home in an orchestral setting.

OLED Display - A small 1 inch display will be recessed into the top of the instrument with a 5 way navigational button allowing for menu driven settings configuration. It can also be configured to display the current values of sensors in real time in bar or number format. Here's a sample of the OLED:

I hope this answers some questions!
