VCS-UltraPhazer [Multi-Oscillated Phaser] by Virtualcreations
VSTWin added 06/07/2002

VCS-UltraPhazer is a multi-oscillated VST phaser plugin for Windows. It sounds very cool on guitar tracks and on raw saw sound. There are 14 sliders you can control, Resonance, Min Filter, Max Filter, LFO Freq, LFO Add 1-3, Filter 1-4, Num Filter, Stereo Phaz and Mix. Version 1.1 comes with simple soft clipping, no denormal behaviour, auto preset loader, bugfixes, P4 compatibility, faster LFOs...
Chorusifier [Chorus Effects] by Green Oak
VSTMac added 05/11/2001

The Chorusifier is optimized for the G4/Altivec vector processor. Includes presets for chorus, leslie, flanger, doubler, and sitar. Check these out by selecting programs 1 through 5. Works best as an insert effect...

Small gadget to transform your sound (works in stereo).
Bass Chorus [Chorus/Flanger] by Clone Ensemble / Trevor Magnusson
VSTWinDirectX added 20/11/2001

Bass Chorus is a full featured chorus / flanger (including thru-zero) with 4 modes, and an option to leave the bass frequencies of a signal alone - ie, only process the mids & treble. This lets you create huge, wide bass sounds without sacrificing punch and focus. It's ideal for electric guitar and synth bass, but sounds great on anything that needs a chorus or flanger...
VFlanger [Flanger, with L/R phase control] by Vellocet
VSTWinMac added 25/10/2001

Parameters:Rate: (0 - 4 Hz) Flanger sweep rateMin: ("44100" - Max Hz) Highest frequency swept to (minimum phase difference)Max: ("44100" - 171.6 Hz) Lowest frequency swept to (maximum phase difference)Swap Chan: (On / Off) Swaps the L/R of the phase altered signal (kinda chorusy)L/R Phase: (0 - 180 degrees) phase difference of the left and right sweep.Feedback: (0 - 100 percent) "flanger position" enhancing feedback.
VdPhazor [Randomize subband phase (FFT)] by Vellocet
VSTWin added 05/11/2001

Sub band phase randomizerParameters:More info to come, I promise.... FFT Size 2^7 - 2^16 samples Randomness - percent (this isn't optimized by a long way yet)
SupaPhaser 2.0 [Phaser] by bram @ smartelectronix
VSTWinMacBeOS added 19/08/2002

3 to 23 (yes, 23) stages phaser with feedback. Phaser operation is controlled by a mixture of LFO and envelope follower, both configurable. Enhanced stereo effect. Pre-phaser distort or saturate. Post-phaser gain. Mixture: defines the mixture of envelope detection and LFO. Attack: sets the attack of the envelope detector. Release: sets the release of the envelope detector. Min(env): sets the minimum depth of the envelope detector. Max(env): sets the maximum depth of the envelope detector. Freq: sets the frequency of the LFO. Extend (that little button): extends the frequency range of the LFO (off: freq between 0 and 2Hz, on: freq between 0 and 10Hz). Stereo: defines the stereo spread of the LFO (phase difference between left and right). Min(freq): sets the minimum depth of the LFO. Max(freq): sets the maximum depth of the LFO. Distort. Feedback: how much of the signal is fed back to the algorithm. Stages: number of stages in the algorithm. Dry-wet. Gain.
