C++ MIDI Sequencer Build

I’m looking for a seasoned C++ developer to help add features to MIDI controller / sequencer code. The microcontroller is a Teensy 4.1 with an 8 bit TFT screen, encoders and buttons. I am looking to add a MIDI clip launching feature.
Scope
• Implement a responsive performance mode with low-latency note triggering, tempo-sync’d clock, and real-time parameter tweaking.
• Add a recording & editing workspace: non-destructive takes, quantize options, basic piano-roll view, and undo/redo.
• Build an automation lane that can record CC data live, draw curves, and play them back with sample-accurate timing.
• Provide a straightforward UI that feels at home on macOS (native widgets or a cross-platform framework—your call as long as it’s smooth).
• Ensure seamless MIDI I/O with USB keyboards, DIN drum machines, and AU/VST plug-ins hosted on the same Mac.
• Deliver a functional prototype, well-commented source code, and a short README so I can compile and extend the project later.

Nice to have
If you’ve worked with hardware MIDI controllers, device discovery, or time-stretch algorithms, let me know—there’s room to grow the feature set once the core is stable.

Think you can craft a tight, musician-friendly sequencer in C++? I’m ready to get started.
