Would you be talking about microtonal tunings? We have Scala for Renoise here:
You can also program your own tunings into this, out of the 4,000 included. It’s a great Tool for making more abstract tunings. Meaning, you can tune your keyboard to play notes at whatever distance between that you like. The method of programming these tunings is relatively easy, you’ll have to research the “how” using the forum, or the Internet, but from a non-programmer’s perspective (me), it’s not hard at all.
The only thing may be that it’s not a global tuning, but per-instrument. Some extra steps involved, but not awful.
