Since SB they’ve shown pictures of their UB-Xa, which is done except for the firmware, and manufacture. And they showed pictures of their Solina String Machine Eurorack (a semi-modular !?) which is in a similar state of development.
The CAT will be in stores in two weeks.
I posted these in threads here, here, and here.
I still expect the 2600 to be announced and show up in stores fairly soon but no word yet.
