## Summary

Roger Linn, founder of Roger Linn Design, discusses the engineering and philosophy behind his expressive musical instruments, specifically the LinnStrument and the upcoming AdrenaLinn drum machine. He details the custom 3D sensing technology using force-sensing resistors (FSRs) and key matrix scanning to achieve low-latency, polyphonic control, while addressing technical challenges like n-key rollover and jitter. Linn also shares insights on his solo business model, the strategic use of Raspberry Pi Compute Modules for embedded audio processing, and the importance of open-source software in building a developer community.
