RFX Flanger
The RFX Flanger is a true stereo sweeping flanger with an extensive
modulation section and special features not found on other flanging
devices. It can achieve flange delays with a combination of fixed offset and
swept delays from 0 out to 80ms in .1ms increments. The flange sweep can
take a number of different shapes, and its rate can be sync'd to the system
tempo, tied to a MIDI-controllable LFO, or driven directly by MIDI/synth
modulation.
The simplified block diagram of the RFX Flanger is shown below.
