This device is really great thank you, I’ve been using M4L macros in Ableton to get a stereo version working.
One thing I’m looking to do is use some kind of Macro button (this would work https://maxforlive.com/library/device/5353/simple-one-button-macro) to bang specific values for the ‘Coarse’ and ‘Fine tune’ controls so I can get eg a Fifth or a Seventh instantly. Currently in Ableton all the Macros default to a 0 - 100% range which I don’t think you can change.
Are there any more succinct ways of achieving this? btw I’m no programmer and don’t own a copy of Max so my current option is to have a row of huge ‘Off’ ‘On’ buttons.
