Carlo Serafini plays an Opal Chameleon and a Nord Stage 88, both tuned to Carlos Gamma, but using different note layouts.
Here’s what Serafini has to say about these jams:
These videos demonstrate that it is possible to move from one keyboard to another with relative ease even though they do not share the same note layout, as explained on the above mentioned article. In fact I had never played those two keyboards at the same time before and, as you can see, their position is not particularly ergonomic, nevertheless it is feasible, at a glance, to conjure up some music. You can hear that I move back and forth from a somehow major to a somehow minor tonality.
The usefulness of this technique lies in the different spatial placement of notes the two keyboards permit. Simple phrases on one of them are usually very hard on the other one and vice versa.
More information on Serafini’s explorations with microtonal tuning and alternate keyboards is available at his site.
Carlos Gamma is a microtonal tuning system developed by electronic music pioneer Wendy Carlos. Details here.
