sonus

A simple synth music app using https://github.com/fr3fou/beep

• Render multiple keys
• Support for pressing several keys at once / play more than 1 note at once
  • Remove / shift the samples from the buffer as they get played - Use a channel instead of an array buffer?
  • Add up the "conflicting" (the ones that match) samples when copying the new note into the buffer - Would have to change from using the copy function to a manual process
• Configurable generators
• ADSR
  • Adjust ratios
  • Handle triggering and releasing (https://github.com/velipso/adsrnode#triggering-and-releasing)
• Note duration based on hold duration
• Fix clipping
• Support for continuous notes (no gap between individual notes)
• Support for singular notes
• Better piano keys
• Reverb
• MIDI Input
• Octave labels
• Octave changer
