Maybe true. Indeed we are not able to generate realtime capable source
code direct from a (nonlinear) circuit schematic, it's to complex. A lot
to resolve. But we work on it.
Alone the build script for the jcm800pre takes 288 lines python, and a
couple of optimization steps are needed to get it at least run with
~20%DSP load. But the result is indeed passable in terms of how it
sounds lately.
Clearly a picture from the beach isn't the beach. :-D
