The .scl file is the lingua franca of microtonality — a tiny text format holding any
scale as ratios and cents, with a public archive of nearly five thousand of them. Drop one here (or
paste it) to hear it and re-export it for whatever your synth reads:
.scl, an AnaMark .tun keyboard table, a MIDI Tuning Standard
sysex dump (.syx), or an MPE .mid of the scale. Files never
leave this page.
The .tun and .syx map the scale across all 128 MIDI keys with the tonic on
middle C (key 60): one key per degree, wrapping each period. .tun loads into many soft
synths (Surge XT, u-he, Pianoteq…); the .syx retunes MTS-capable hardware and soft synths
via any sysex-sending tool. The EDO and
tunings pages export .scl straight into this page.
