Filter Parameters - Cutoff Frequency And Resonance; Cutoff Frequency - Yamaha MU15 Owner's Manual

Filter Parameters — Cutoff Frequency
The MU15 features digital filters for each Part that allow you to change the
timbre or tone of the Voices. The filters are affected (together with the level)
by the EG (Envelope Generator) parameters, which allow you to change the
timbre over time as well. (Page 52.)

Cutoff Frequency

setting
Range: -64 - +63
Default: 0
This determines the cutoff frequency of the filter. The filter effec-
tively takes out frequencies higher than the cutoff point and
"passes" the lower frequencies. Lower cutoff values create a
deeper, more rounded tone, while higher values create a brighter
tone.
