hm, i began to play with my old koblo projects the other day, it is still a field to explore. i almost got a polyphony solution working for the 2.5 release which end users have.
maybe one day i reassemble a vibra 9000 with the developer tools where i add full midi CC controllers and polyphony. because these are the things which are really missing to make it even better.
from the viewpoint of Max/MSP as main program absynth 2, tokyo, UAD and powercore are the perfect generators, as traditonal VST hosting is very expensive in this host.
and koblo did a great job with a very clean and fast (one vector) inter application audio streaming - with 16 channels and for MacOS 8.6! the stuff was so much ahead of its time and the majority of ignorant comsumers have almost forgotten this wonderful software.
