I'm currently working on an Audio/Midi Recorder/Arranger for musicians/songwriters.
Admittedly it's not a Startup, I rather aim to make it a SMB some day.
And yes, hardware is hard. Especially for me as a Software Engineer by trade.
Track8 started when I wanted to learn Rust 3 years ago. It somehow evolved into a product.
