UltraTap & TremoloPan have many situational uses.  Once you reach that fixed level threshold point, though, your signal drops off a cliff.  Something you have to plan on, and work around.  A dream scenario for me would be to divert the envelope follower in PolySynth away from its oscillators, and process the input signal with it as an optional routing.

Internal to the H90, the Omnipressor mode in DynaVerb is my most-used algorithm for ‘slow gear’.  Ducked Delay has a different flavor, more of a slow-burn.  Fits well when it’s feeding a 2nd effect.  What they both have in common is control over the compressor’s Release time & Threshold level.  Always critical adjustments for a good match to your instrument, technique, and input signals.

In the little test-pilot Program attached, a matched range of both Releases & each Threshold are accessible from the HotKnobs.  The default settings + three HotSwitches toggle among short & long Release times in either DynaVerb & Ducked Delay.  For side-by-side comparison, HotSwitches also trigger faux-Bypass.

The Omnipressor mode is locked to Gated here, but other Omni Ratio values can fine-tune the results.  (I do wish the Attack time covered more range, but it’s emulating unique, vintage hardware).  I couldn’t resist adding in a side-feature or two.  EXP1 sweeps through reverb decay times, infinite & freeze, for an ’80’s gated reverb effect.  EXP2 for a foot-controlled volume effect & boost option.
