+# metabolus
+
 A QTWidgets C++ app for a basic digital synthesizer.
 
 This synthesizer isn't very good, but it's neat :3 
+
+## Development plan: 
+- [x] Build & project setup, get working hello-world program.
+- [x] QTWidgets hello-world program: basic increment/reset counter
+- [x] RtAudio hello-world: basic sine output
+- [x] Connect UI control to sound output, add a slider for frequency control
+- [ ] Add note control via either Midi or a keyboard. Coordinate on-off events to
+      start and stop tone generation
+- [ ] Create a widget for this smart-slider to clean up the ui code
+- [ ] Add envelope generation, attach to global volume for now. ADSR and such,
+      responds to note-on/note-off events
+- [ ] Make midi/keyboard control cross-platform. Use case will mostly be
+      Midi -> linux and Keyboard -> windows though
+- [ ] Create oscillator class where the actual tone generation occurs. Multiple
+      oscillators increase the sound complexity considerably
+- [ ] Create a UI scope to visualize the synthesized composite waveform
+- [ ] Create wavetables for more complex tone generation. Needs to be selectable from ui
+- [ ] Create digital filters, prob biquad. Controllable from ui obv (cutoff + resonance)
+- [ ] Add polyphony somewhere. Probably involves a voice class. If processing power
+      allows it, tie a voice to each midi note
+- [ ] Add noise ? 
+- [ ] planning gets sparse this far out because its how far I got with the ESP32 synth
