• 04: Cutoff Freq
❑
Cutoff Frequency
❑
Settings: 0 … 127
Sets the cutoff frequency of the selected filter. Lower cutoff values produce a lower cutoff frequency and higher
values produce a higher cutoff frequency. With an LPF response (selected by the “Type” parameter, above), a lower
cutoff frequency reduces the range of high frequencies passed, making the sound “darker” or “rounder.” With a HPF
response, a higher cutoff frequency reduces the range of low frequencies passed, making the sound “thinner” or
“sharper.”
• 05: Resonance
❑
Resonance
❑
Settings: 0 … 127
Determines the degree of filter resonance. This parameter has a similar effect to the “resonance” settings on
traditional analog synthesizer filters - i.e. it determines the height of a peak in the filter response at the cutoff
frequency.
Higher resonance values produce a higher resonant peak and reduce the overall bandwidth of the filter, passing a
narrow band of frequencies at the filter’s cutoff.

Frequency Scaling
❑
Settings: -64 … +63
• 07: F.Scale BP
❑
Frequency Scaling Breakpoint
❑
Settings: C-2 … G8
The FreqScaling and F.Scale BP parameters work together to produce a variation in filter cutoff frequency across the
range of the keyboard or other MIDI controller used with the FS1R.
When a positive FreqScaling value is specified (“+1” … “+63”) the filter cutoff frequency increases to the right of the
breakpoint specified by the F.Scale BP parameter, and decreases to the left of the breakpoint. On the other hand,
when a negative FreqScaling value is specified (“-1” … “-63”) the filter cutoff frequency decreases to the right of the
breakpoint specified by the F.Scale BP parameter, and increases to the left of the breakpoint. The higher the value
the greater the change in filter cutoff frequency.
Please note that the breakpoint will shift in accordance with the settings of the Note Shift parameters (pages 24, 40,
59, 71).
