Filter - Yamaha FS1R Owner's Manual

• 03: Key Sync
Key Synchronization
Settings: off, on
Determined whether the LFO runs continuously (off), or is triggered by notes played (on) so that modulation always
begins from the same point in the LFO waveform when a note is played.
• 04: Phase
Phase
Settings: 0, 90, 180, 270
Determines at which point in the LFO waveform the LFO will begin operation. The values correspond to phase
angles in degrees. The illustration below shows how the various phase angles correspond to points on the LFO
waveform (a sine wave is used for clarity).
• 05: FilterModDpt
Filter Cutoff Modulation Depth
Settings: 0 ... 99
Sets the maximum amount of filter cuttoff modulation that can be applied to the current voice. A "0" setting produces
no modulation while a setting of "99" produces maximum modulation. Filter cutoff modulation produces wah-wah
type effects.

• 01: Part Switch
Part Switch
Settings: on, off
Turns the filter "on" or "off" for the current part. This parameter is actually EDIT [PERFORMANCE]/PART/Tone
parameter.
• 02: InputGain
Input Gain
Settings: -12 ... +12
Adjusts the input gain of the filter. The gain can be reduced ("-" settings), for example, to compensate for the
increased gain produced by high resonance settings, thus reducing distortion. On the other hand, the gain can be
increased to deliberately produce distortion when desirable.
