SWEEPER MODULATION EFFECT1115
•MFB HP 24dB
A multiple feedback (MFB) highpass filter with a 24dB/octave slope. If you turn up the Resonance high, additional
resonance peaks appear.
! Be careful when using this filter type as high Resonance values could generate quite extreme audio levels!
• K35 LP 12dB
An “early MS-20 type” of lowpass filter with a 12dB/octave slope. The filter can be driven to self-oscillate.
! Be careful when using this filter type as high Resonance values could generate quite extreme audio levels!
LFO
The LFO can be used for cyclic modulation of the Frequency parameter of the Phaser/Flanger/Filter section - and/
or for modulating the Volume. The LFO Rate can also be synced to the Reason sequencer. You can also modulate
the LFO Rate from the Modulator (see “The Envelope Modulator” and “The Audio Follower Modulator”).
Waveform selector
D Click the up/down triangles - or drag the waveform display up/down - to select the desired LFO waveform.
Ten different LFO waveforms are available. Besides the standard waveforms (sine, triangle, pulse, etc.) there are
random, slope and stepped waveforms. The shape of the waveforms are shown in the display.
! Note that all waveforms except the “Decay” are bipolar, i.e., they generate both positive and negative levels.
