BetaBlocker vortual chip implementation. The heap is realised as a Buffer and can possibly be shared with other instances. It triggers the computation of the underlying BetaBlocker engine at a given rate and returns an array consisting of the program counter and all 8 stack elements re-scaled to values between -1 and 1.
Pointer to the buffer where the heap is stored. Can be modulated at control-rate.
Initial position of the program counter.
