In an attempt to create a better sounding phaser than what CWA has, I made a three-stage notch sweeper that sounds like a phaser. Has some nifty features...there's feedback that doesn't make the bird chirping sound like phaser feedback, but it can make some other interesting sounds. The feedback goes through a delay, which goes from 4ms to 682ms, and it also goes through a bandpass filter. The combination of the notch filters and the bandpass delay can create interesting effects -- and because the notch and bandpass "shift" knobs are smooth, you can do external MIDI control.
Explanation of controls:
"FreqShift" controls the center postition of the LFO, and if the LFO is off (Depth=0), it controls the filter notch position. Because the knob is interpolated, you can control it smoothly via MIDI.
"Rate" controls the LFO rate for the notch filters. The three notch filters are set slightly apart from each other to get a big sound.
"Depth" controls the LFO depth.
"Stereo" delays one channel slightly from the other to create a stereo effect.
"FB Level" controls the feedback/delay/bandpasss level.
"Delay Time" controls the feedback delay time.
"Delay Shift" controls the center position of the bandpass filter LFO on the feedback channel. When depth=0, it controls the bandpass filter position. This knob is smooth too.
"Rate" controls the LFO rate for the bandpass filter on the feedback.
"Depth" controls the LFO depth for the bandpass filter on the feedback.
"Dry" and "Wet" do exactly what they do.
When changing the rate and depth for the two LFOs, you'll probably have to adjust the two "shift" knobs. I don't know why that is for when you adjust rate, but you have to.
That's about it...it sounds pretty good. Dry is usually off unless you want to minimize the sweepy sound.
Please tell me what you think!
Cheers,
Shayne
