Gary,

What band are you on? With the original synth, actual 1-Hz step size will be slightly larger on the highest bands due to quantization at the DDS. I don't have exact figures but if you have an extremely accurate external counter, you could determine actual step size on each band.

The new synth provides much finer gradation -- typically 0.1 to 0.2 Hz -- on all bands. So a 1-Hz step will always be very close to 1 Hz.

73,
