FM - Continued: Frequency Ratios
Modulator @ 130Hz
Carrier @ 65Hz
Ratio = 2:1
The frequency ratios and modulation index define
the tone and harmonic content of the resulting sound.
Specific frequency ratios will create harmonic and
inharmonic sounds, as previously described, and the
Z3000mkII allows the user to precisely set those ratios
in any of its three modes.
While playing an FM patch across a range of several
octaves, the frequency at these octaves may not
maintain the frequency ratio that was set at another
octave. This variation in frequency is an inherent
feature of analog VCOs. The Z3000mkII makes it
possible to overcome this issue by fine tuning the
desired frequencies at both ends of the range until
both are set accordingly for smooth harmonic sounds
spanning several octaves.
