The cross-talk between the tonewheels is adjustable and 11 additional tonewheel sets are also included: 'Cosmetically age' the B4 II or transform it into a Farfisa, a Vox Continental or an Indian Harmonium.
Or turn the B4 II into a completely different organ altogether: the Farfisa, Vox Continental and Indian Harmonium are all included.
B4 II is available individually or as an attractive bundle with the B4D drawbar controller.
The aim of the B4 is to not only run at a high clock rate but also to allow high levels of parallel operation for both integer and floating point operations.
This B4 project began after I read about the sort of processing going on in things like hardware 3D graphics accelerators where there are a great many operations going on at once.
The B4 is however not a multiprocessor and does not require the communication overhead in either hardware or software, additionally it cannot fight itself for memory access.
