About

Hi, I'm Long Kelvin.

K Instruments is my one-person studio. I'm a software developer and a musician, and most of what I build comes from the gap between the two: tools I wished I had on stage, at rehearsal or in the DAW.

SoundDeck began with the people who run sound at weddings, galas and conferences, who need a player that never surprises them mid-show. MIDI Chord Detector began at the keyboard, wanting to see the name of the voicing under my fingers. song-rt-scription takes that idea from MIDI to recorded music.

I care about low latency, clear controls and software that does the same thing every time you press the button. I design, build and support everything here myself.
