DEVs on what you are currently working on? Redux update?

As taktik said:

we’re currently indeed busy with something else which has nothing directly to do with Renoise, but may benefit it on a long term

You should assume that “nothing directly to do with Renoise” refers to the whole Renoise/Redux family, since they are very tightly linked.

It’s something else that’s being worked on: something non-Renoise, non-Redux.
