Tuning Editor - Max For Live

Tuning Editor gives Ableton Live users access to the native tuning system allowing editing of the Live sets currently loaded tuning steps. Tunings are updated in real-time, saved in the Live set and optionally exported as a new .ascl file.

Key features:

- Modify tuning steps for the Live set.

- Update tuning system in real-time.

- Display note frequencies in Hz for each octave.

- Optionally set tuning by frequencies.

- Rename the tuning.

- Export tuning as .ascl in Live.

Note frequency Hz values are displayed per octave alongside steps. Min and max step cents range are adjustable and can be set to positive or negative values. The max range is 1200 cents by default unless a tuning is loaded with a higher step value, then the highest step value will be set as the maximum.

Current limitations of the Live API mean that the last step, or 'pseudo octave' cannot be modified and maintains it's value from the loaded tuning file. The first step is always 0.00 cents as per the .ascl specification.

Refer to https://tuning.ableton.com/make-your-own-tuning/ on creating your own tuning .ascl file. You could create a tuning with the tools on Ableton's page, then use our Tuning Editor to tweak the steps in real-time while using Live's instruments, or play and tweak with the tunings bundled with Live to something that feels right to you.
