Thumb not touching any pad is the 'home register':



I made this D4 to C#5 on gewi.

Rolling the thumb down a bit sets the octaveShift variable to -12:

It's a handsome piece of kit too!

I keep wanting to delve into DIY electronics, as I'd like to further modify my keyboard, but I'd have to have a very good brainpower day for it. I can only admire those who take the plunge with success. :D

Hi puremusic,

Maybe you could start a thread describing your keyboard modifications?

www.pjrc.com/woodwind-midi-instrument/

shows how easy it is using Teensy microcontroller.
With Teensy boards you just connect the teaspoons or whatever, write or download some code and plug it in.
It really is as simple as that.
A broomstick will do, with some finger pads.
All the electronics is built into the pressure sensor and the Arduino/Teensy, you just connect the wires.

My cat Max could do it if he were human!
(Max prefers Respiro to the acoustic flute).

The aim with gewi was to make it lighter and easier to change octaves than the Akai ewi's I had previously used.
I prefer a six pad fingering, using the pinkys for support and potential auxilliary functions.
(gewi fingering G# is now 110100 and D# 111011)
Modulation controls take a back seat for me, I have been using CC02 mapping mostly.
I use a simple vst host (no DAW).
Tobybear's Minihost has a great mapping facility, but 32 bit vsts only.
You can set the maximum and minimum effect to any parameter in the VST.
Respiro is 64 bit only so I guess Reaper might do the same, haven't tried it though.

Cheers, Reg, and thanks to Rudy for making this space available.

This photo shows Johan's contribition to gewi:



Just two sheets of plastic
(smoke Polycarbonate in gewi)
screwed together. The wires might look complicated, but they just connect the finger pads to the microcontroller breakout board)

Really cool Cat you have ;-)
I'm convinced that a time will come where musicians without know-how of electronics will be able to assemble there own customised expressive controller. I have plenty of ideas on this, but first I need to Max-imize the features of Respiro..
Keep up the inspiring work....
