The EEGsynth
With my first post on the Arduino based CV/Gate controller I implemented a single control channel using a single DAC. Now, using four TI LF398 sample-and-hold ICs, I multiplexed the DAC output into four control channels. I updated the Arduino sketch and managed to control all four outputs independently. However, something that I overlooked is […]
I wrote some code that wraps the serial interface and the control commands of the Arduino CV/Gate into a MATLAB class. I used the following example code in MATLAB to benchmark the speed. a = cvgate(‘/dev/tty.usbserial-AH01DRO4’, 115200); a.voltage = 0; a.gate = 0; c = 0; t = tic; while true a.voltage = 5 * […]
We had our first EEG-Synthesizer jam with a smoothly working setup! Quite a milestone! In the following video and SoundCloud recordings (removed), you hear several interesting and evocative synthesizer patches created by Jean-Louis that are fully controlled in real-time by the EMG signals from my hand and arm. So in fact, during the recordings Jean-Louis was […]
The EEG signal processing, classification and the translation into a control signal is done on a computer. This means that the computer needs to be able to send control signals to the synthesizer. There are in general two options for interfacing with a synthesizer: Midi and CV/Gate. Midi is a digital protocol over a serial […]
