By attaching electrodes to the leaves of a plant or skin, fluctuations in galvanic conductance will produce MIDI notes, which are transmitted on a configurable MIDI channel. With a maximum of 5 note polyphony (matching the LEDs).
Through sampling pulse widths and identifying fluctuations, MIDI note and control messages are generated.Features include Threshold, Scaling, Control Number, and Control Voltage using PWM through an RC Low Pass filter.
Note that you do need a software or hardware MIDI synthesizer to use this device.
It uses the same galvanic conductance sensing circuitry known from Sam Cusumano’s MIDI Biodata Sonification System but runs a modified firmware and has some nice addons:
A control message is transmitted on CC 80, which is also presented as a 'Control Voltage' output via an unpopulated pin header - to modular synthesizers and equipment.
For more information about the device, usage examples and to share experiences, join the MIDI Biodata Sonification forum hosted by Sam Cusumano, who originally designed this technology.
A basic set of accessories is selected by default. A ready-to-use configuration with almost everything to get started. (except 3x1,5V AA batteries!)
Currently the electrodes and cables are not available separately, but I will add them in the near future. You can contact me for replacement parts in the meantime.
The enclosure is available standalone: Enclosure for MIDI Biodata Sonification Device
If you choose the "custom color" options, let me know the color of your like me via email (info@13-37.org) or via Tindie message. You can also add a note during checkout.
Also feel free to ask for colors that are not listed yet.
Sometimes failed prints of the enclosure are available for reduced prices or even free. These have optical defects but will work fine.
The settings menu works with an extra button and the knob to set threshold, MIDI channel, note scale and LED brightness.
In the first menu level, you can select the setting to be changed by the following color coding.
| Setting | LED color | Description |
|---|---|---|
| Threshold | red | Selectivity of the electrodes. Moving it further away from the OFF-position decreases sensitivity. |
| Note Scale | yellow | Chromatic (red), Major(yellow), Indian(green) and Minor scale(blue) are available. The corresponding LED flashes after entering this setting and the scale can be selected using the knob. Press button to apply and leave the menu. |
| MIDI Channel | green | Select MIDI-Channel 1-16 by turning the knob. Current channel is displayed in binary format using 5 LEDs. See reference below. |
| LED Brightness | blue | Select LED effects brightness. From zero to full by using the knob. Blue LED is flashing to indicate the selected brightness. Can be used to save some power. |
To restore default settings, press the button during power-on. It will acknowledge the reset by blinking white.
In the MIDI channel configuration (green menu), the currently selected MIDI channel is displayed binary encoded using the five available LEDs. If you're already familiar with binary calculations, you can easily calculate the channel by remembering that the least significant bit (LSB) is the red LED.
You can also use this reference table, so you don't have to do any math:
The device is available as as DIY Kit with only the surface-mount components pre-soldered or fully assembled as selected by default.
These parts have to be soldered in the DIY Kit:
