Pyblaster is a monophonic syntheziser with Midi, ADSR, LFO and Filters (Lowpass and Reverb). It's inspired by Korg's Kaossilator series and provides a touchpad which controls two parameters simultaniously (eg. Pitch and Lowpass). It can also be used with a Midi Keyboard.

• 3 Waveforms
  • Triangle, Sawtooth, Rectangular
• 4 Phase Envelope
  • Attack, Decay, Sustain, Release
• Filter: Low-Pass, Reverb
• Midi-In
• LFO (to controll pitch or low-pass)
• version with GUI and version which can be run from console

install all required libraries

• Pyaudio
• tkinter
• Python 3
• python-rtMidi
• Scipy
• numpy

run with gui: python3 /synthlogic/main/synth_gui.py

OR

run without gui: python3 /synthlogic/main/synth_no_gui.py

change settings of synth in config.ini

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/

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