Detailed Description

band limited pulse generator

pulse generator

corresponds to BUZZ unit generator in other synthesis environments.

TODO: fix this unit, it appears to have a rounding problem induced by incrementing the phase each step, after some time the divisor and the dividend seem to shift appart. TODO: observe how the output evolves after x mins, is the amplitude always rising? Changing the WaveTable size had some effect but not the desired.
