npSynth, a digital synth with two analog modules: https://hackaday.io/project/160780-8-channel-surround-sound-synth-with-analog-filters This is the current integration state: - physically connected on a plywood slate, the same material the case will be made of - power is all wired up, with a new 12v to 5v BEC powering the raspberry, arduino and its usb connected devices (1,5A sustained). - I had to up the voltage to the arduino to 5v to supply enough voltage to the analog modules. As the raspberryPi is a 3v3 device, i unhooked the TX pin of the arduino, as i'm not receiving data from the arduino anyway and it contains the 5v voltage that would hurt the Pi. 3v3 is enough for the arduino to receive the data from the raspberry. I also had to up the serial speed to 115200 to have a fast enough response from getting the midi command, to transmiting it to the arduino and getting the voltage changed. It works but stops working after a while. Serial is such a mysterious pain in the butt, I'm going to have to research it a bit more:) The soundcard just plays a loop but it's the actual npSynth software running it.
