201 / Septavox MIDI Out Transposition

Hello, I recently have acquired an Organelle, and I’m getting on really well with the wooden keys; they’re so tactile and pleasing. As I look to eventually add another C&G synth to run through the Organelle, being able to double one as a MIDI keyboard would be an added bonus.

That being said, I know the Organelle has fixed note values for the most part (I have the Rusted Keys and MIDI Control Keys patches) and that transposition happens in the synth engine. However, since the Septavox and the 201 Pocket Piano have octave up and down functions, do those happen on a MIDI level and send that info out as different notes once transposed?

Hope that makes sense, and any insights would be helpful, thanks!
