After feedback on the tactile aspects of Planxtone, I decided to inlay the sensors on the circle of 5ths. This has turned out to be time consuming because of the cutting properties of MDF. MDF was used initially as its electrical properties facilitate sensors to be hidden underneath. I've found plywood makes sensors less sensitive (properties of the glue?). I decided to put the sensors on the front because of their visual aspect. So next time if I inlay it will be plywood! All part of the learning process.

Reading up on on Teensy 3.2. Appears awesome, but need to actually test it out and see if it actually delivers.

New challenge. This is to create an instrument for someone who is deaf and partially sighted. So I'm thinking haptic.

Some experimentation with MIDI to make it more flexible in sound generation. Being able to pan left and right would be useful. This would allow Ch1 to fire out on left channel and C2 on the right. There are a lot of cheap stereo class D amplifiers around and splitting make for easier construction.Also got neopixels up and running, but that is for another day. code snippet for Arduino / VSLI 1053B

talkMIDI(0xB0, 0x0A, 0);//0 is channel 1, balance 0 = left, 127 right, 0A pan sends Pan message
talkMIDI(0xB1, 0x0A, 127);//1 is channel 2, balance 127 =hard right, 0A sends Pan message

Adding some colour. It would be nice to either colour code or "swirl" the paint like a cyclone, but I want it up and running for Xmas Bytes at TNMoC. 28th to 30th Dec.

Planxtone
Now fully working. 4 instruments, Keys of C, G, D and F major and 5 octave shifting.

Circle of Fifths 01
Started work on a "Circle of Fifths device. 2ft square MDF board and a dozen rectangles of chopped up PCB.

Running my pin test routine showed up a number of problems on the Planxtone hardware. Rotating the resistive network switch showed it had developed a fault. i.e. on the 6th position it was shorting the 5v rail to earth. As a work around the switch was reduced to 5 selections. There was a problem that the binary selection on pins 6-7 was showing a "short" between the two. This turned out to be some conductive ink from a prior use of the board was shorting the pins out. Sorted by a thorough clean.
