Yamaha RY30 - Job 01: Filter Type; Job 02: Cutoff

VOICE EDIT MODE
Procedure: Press [ENTER] and then use the
[PAGE-] and [PAGE+] keys to select the
desired job.
Press [EXIT] to exit from the filter job mode
and return to “FILTER ?” display (page 07).
JOB 01: FILTER TYPE
High Pass Filter Response
Summary: Independently sets the type of filter
response applied to waves 1 and 2 of the current
voice.
Settings: Wave 1 filter type: THRU, LPF12, LPF24,
HPF12, HPF24
JOB 02: CUTOFF
Wave 2 filter type: THRU, LPF12, LPF24,
HPF12, HPF24
Procedure: Use the and keys to move the
cursor to the wave 1 filter type or wave 2 filter
type parameter, then use the [INC] and [DEC]
keys or the [DATA] slider to set as required.
Summary: Independently sets the filter cut off fre-
quencies 1 and 2 of the current voice.
Notes: The “THRU” (THROUGH) setting turns the
filter OFF.
The “LPF” (Low Pass Filter) settings pro-
duces a filter response that allows only fre-
quencies
below the cutoff frequency to pass (see
"CUTOFF” job below). The “‘LPFI2” setting
has a 12dB per octave cutoff slope, and the
“LPF24” setting has a steeper 24dB per octave
slope.
Low Pass Filter Response
The “HPF” (High Pass Filter) setting produces
a filter response that allows only frequencies
above the cutoff frequency to pass (see
“CUTOFF” job below). The “HPF12” setting
has a 12dB per octave cutoff slope, and the
“HPF24” setting has a steeper 24dB per octave
slope.
Settings: Wave 1 filter cutoff frequency:
LPF 0.00 . . . 22.4 kHz in 128 steps
HPF: 0.00 . . .
11.7 kHz in 115 steps
Wave 2 filter cutoff frequency:
LPF 0.00 . . . 22.4 kHz in 128 steps
HFF: 0.00 . . .
11.7 kHz in 115 steps
Procedure: Use the and keys to move the
cursor to the wave 1 filter cutoff frequency or
wave 2 filter cutoff frequency parameter, then
use the [INC] and [DEC] keys or the [DATA]
slider to set as required.
Notes: With an LPF response, a lower cutoff fre-
quency reduces the range of high frequencies
passed, making the sound “darker” or
"rounder.”
With a HPF response, a higher cutoff fre-
quency reduces the range of low frequencies
passed, making the sound “thinner” or
"sharper.”
