Nice work, really enjoying it!
I've not heard of the DarkStar before, how would you describe the sound, compared to the TI? Which sounds on your tracks are typically being provided by the DarkStar?
I've got a TI Snow and an old Electribe ES-1, working happily together, but do need more polyphony, so wondering what else to add. Might grab an Arturia Keylab, unless something else jumps out as a much better option.
Cheers,
