SINGLE: Edit
Edit Frequency?
This is where you set the frequency of each operator. Each operator can be set
to Ratio or Fixed mode. In Ratio mode, the frequency will depend on the key
you play. In Fixed mode, the frequency will be the same no matter which key
you play. This can be useful for special effects, or for creating “formants”
(fixed characteristics of spectral emphasis found in human voices and some
instruments).
Answer YES to this display, and use the PARAMETER keys to select the
coarse (CRS) and fine (FIN) frequency adjustment for each operator 1-4.
By moving the cursor to (xxx), you can set the oscillator mode to RATIO
or FIX.
If Fixed Mode is selected, you can set the Fixed Frequency Range (see below).
Ratio (0.50-27.57)
The “standard” ratio is 1.00. le. when a operator is set to
1.00
frequency ratio,
it will produce a 440Hz tone for an A3 note (standard pitch). A ratio of 2.00
would be an octave higher, and 4.00 would be two octaves higher.
Fix Frequency
(8Hz-32,640Hz)
The fixed frequency is variable over a wide range. (However, due to hardware
limitations, the very highest frequencies will not actually be output.) Fixed
