How to install on Raspberry Pi

running the synthesizer on your Raspberry Pi is currently experimental. It will run but it's not optimized for it. It was testet on a Raspberry Pi 2 B. For those who still want to try it out, here is a tutorial how to install it: http://denicz.info/2020/11/04/how-to-install-eardrum-blaster-on-raspberry-pi/

Planned features

• remove library Scipy and replace waveform synthesis with own implementation
• paraphony
• optimize performance on Raspberry Pi
