MIDI Step Sequencer for QT Py RP2040 with NeoRotary 4 encoders
Single track, 8-step sequencer:
- Each encoder controls one step's note pitch
- Encoder buttons toggle steps on/off
- External 24-pixel NeoPixel strip shows step status and current playback position
- Sends MIDI notes via USB
- OPTIMIZED: I2C reads only after step 8, no encoder board NeoPixels
