The Mk II plug-in has three depths or intensities of flanging: Shallow for subtle and pretty effects, Deep and intense, and Wide for very stereophonic treatments. I like the Manual control knob for my personal touch when implementing the "combing" effect in just the right way for the music and the instrument or voices you have the Mk II processing. I would always automate this control in Pro Tools using the Remote feature and my MIDI keyboard's CC data.

Above the Manual knob is a red LED that indicates the change of the flange and this helps to set up the Remote feature and the action of the Envelope Follower when tracking the source's amplitude exactly as I found it to do well! Something new is the Side Chain input for triggering the Envelope Follower--a definite sound designer's tool!

I also liked the Oscillator mode for a constantly sweeping effect and it can be sync'd to the session tempo grid changing every 16th note and then up to every 16 measures! I used the Shallow intensity to constantly change room ambience behind a pair acoustic guitars.

The Effect Modifier section has been streamlined to just two controls. Bounce simulates a tape recorder's capstan coming to speed and the Depth control to sets the intensity of the effect. Depth set to 100% (or max in phase) adds the dry signal to the delayed signal, and when set at -100% (or max out of phase) adds the polarity inverted dry signal to the delayed signal. The default is 0% in the center position called Doppler. The Feedback control with its Invert button has its own section on the front panel in homage to the original 2U hardware unit!

Other changes are Input and Output level controls with a Limit LED, a very useful inline Low Cut filter for only the flanged signal with a range from 20Hz to 3kHz, and the momentary Retrig toggle to reset the LFO sweep back to its beginning.

Instant Flanger Mk II version 1.1.2 comes in AAX/AU/VST plug-in formats for Mac/PC and sells for $129 but it's free to registered owners of Eventide's Anthology X and Anthology XI software bundles. This new version is well worth getting for the authentic sound of tape flanging instantly!
