6 Pole All Pass
An All-Pass filter is one with a flat amplitude response, but where the phase is shifted, with higher
frequencies getting more phase shift than lower frequencies. When modulated with a sine LFO of
around 6 Hz, a strange vibrato may be obtained. This is the only way to add vibrato to the input
signal.
Mix 1 & 2
• Mix 1 and Mix 2 Blocks: The four meters labeled Voice 1 through 4 monitor the signal ratio
routed through Processors 1 & 2. Please note that setting the Destination of Mix 1 to Output
1 Only and Mix 2 to Output 2 Only is necessary in creating stereo effects. Each Voice’s
position in the stereo spread is set with the Processor Pan control in each of the Voice blocks.
