Korg have announced that they're launching the minilogue xd module
We expect the Staub to just work. What is really exciting though, is that you'll be able to use the minilogue xd module as a voice expander to your existing minilogue xd, giving your 8 voices instead of 4. We expect it will be necessary to load user oscillators to both units, hence we're updating terms and conditions to allow for that scenario without paying extra.
In other words, go ahead and load the Staub to your main and polychained module.
