There is a "scale" listbox which will make sure all notes will be in a specified key. When you play a C or C#, it will play C# for both if you are in the key of C. It's not always two notes mapping into one note, sometimes it is three notes and sometimes one.
I'd like to use it from the perspective of a grid -- so 0 is the first note of the selected scale, 1 is the next note, etc. I guess we would also need an output from the transformer that says how many notes the current scale has in an octave. Then I could indicate scales properly on the grid by highlighting every root note. Say it is D Minor, then every 8th pad will be highlighted in a different color than the rest of the pads. (See Launchpad95 or Push for an example). The transformer module wouldn't really care, it just takes whatever note number (ie grid index) and sends out the right note in the selected scale.
This is the last feature I should need for the Push patches to become really useful. I've been looking into the SDK and it should be pretty straightforward to create the "scaffolding" for everything else, but it would make the project much less heavy if I don't have to code up a new scale transformation module as well.
Thanks for all the additions you've added for me already, senso! Now I just need one more.. It will keep me busy on the anxious wait for Hollyhock 2
