The Rocket offers a multimode filter.
w A detailed introduction of the filters can be found
in the chapter "Sound Synthesis Basics" of this
manual.
Type LP / BP / HP
Selects the filter type:
The LP Lowpass cuts frequencies
above the cutoff point.
The BP Bandpass cuts frequenci-
es both below and above the cutoff point. As a re-
sult, the sound character gets thinner. Use these fil-
ter types when programming effect and percussion-
like sounds
The HP Highpass is useful to thin out a sound’s
bass frequencies. It cuts frequencies below the
cutoff point.
Keytrack Off / 50% / 100%
Sets how much the cutoff frequency de-
pends on the MIDI note number. The
reference note for Keytrack is C3, note
number 60.
Cutoff
Cutoff the frequency for the lowpass and
highpass filter type and the center frequency
for the band pass.
When the lowpass type is selected
via the Type switch, all frequencies
above the cutoff frequency are damped.
When the highpass type is selected, all frequenci-
es below the cutoff frequency are damped.
When the bandpass type is selected, only fre-
quencies near the cutoff setting will be passed
through.
