psynth

Digital synthesizer project for personal entertainment and education.

Development

Dependencies

On top of those listed in the cargo manifest, the following system packages are required (exact package name will depend on your distro):

• pkg-config
• libzmq ≥ 4.1
• alsa if compiling on Linux (see cpal docs for more details)

Hardware device drivers are gated behind the hardware feature flag and will only work on Linux.

TODOs

• Generalize stream pattern to N-channel audio
  • Implement StereoConsumer
• Implement WavWriter to save waveform to file
• Interface with hardware inputs (e.g. MeatSpacePot real-world Pot implementor)
• Figure out sampling/looping scheme -- how should this be implemented?
• Research and implement more filters
  • Define different rooms or parameterize filters::reverb
  • Envelope filters?
  • Band-pass filters?
• Research and implement a few instruments
  • At the very least, a good-sounding digital keyboard and some sort of drumkit
  • Explore possibility of integration of 3rd-party effects (e.g. VST instruments)
• Implement music handling
  • Notes and operations on notes
  • Scales and operations on scales
  • Feeding notes/scales into controls
• Research and implement more controls
  • Consider what a Keyboard might be -- how are the buttons mapped to notes, or to sounds? How is the sound from a keypress fed into a Consumer?
• Implement metronome
• Sort out the 'static situation (shouldn't be a requirement for Generator, Filter types)
  • Currently prioritizing ease of use and functionality over correctness -- 'static as a requirement for Generator has not proven to be a roadblock in any way, and it may be preferable to code littered with <'a> explicit lifetimes
• Implement some form of CLI for psynth-play such that doing new things doesn't always involve modifying the bin/main.rs and recompiling
