Editing or creating a custom tuning scale in Pro 3?

[Maso1968]

Hello, I just bought the Sequential Pro 3, and I need to program an Arabic tuning scale. I found one preset in the "Scale Alt Tuning" , but that preset works only on one scale. So is there a way to create a custom or edit that preset to make a New scale tuning? Any help would be greatly appreciated. Thanks.

You can create alternative tunings with the free Scala programme and then import into Pro 3 although I think that you will first need to convert the Scala file to SysEx using something like Scala2MTS.
Scala has a large repository of scales within its archive and you may find what you are looking for there instead of programming your own.
