Many of the reverb, delay, or H9 Special algorithms can manage infinite or frozen reverb:

I was looking for more of a freeze pedal-type simulation; de-emphasizing the reverb component. To emulate the momentary switch mechanics, bind an external aux switch to toggle between the expression pedal extremes [ “Set expression pedal value (aka HotSwitch value)” in H9 Control ]. That’ll behave like HotSwitch programming, but without the double-tap dancing & latching.
You can use any number of algorithms to achieve similar results. Why not ModEchoVerb? Mirroring the freeze-style pedal, the upper toggle position is FAST, for instantaneous on & off by footswitch. This H9 equivalent is somewhat different; it uses INF response. A FREEZE selection will work, but I like the stronger signal and note layering that an INF setting provides.
Expression Pedal Heel: DECAY 0.05 S
Expression Pedal Toe: DECAY INF
HotSwitch OFF: FLANGR MIX 0
HotSwitch ON: FLANGR MIX 100
Holding the momentary Aux Switch initiates the freeze, and releasing it erases the hold buffer.
The HotSwitch is configured to kick in a flanger over both the dry & processed (frozen) input.

I use my dedicated freeze pedal all the time, at all of its FAST, SLOW, and LATCH positions. It’s probably irreplaceable in my rig (except by that pedal that followed it up).
But an H9 simulation can go so, so much further. Algorithm dependent, I can selectively apply & overlay other effects on the frozen processing, and all within a single unit. Gear the H9 ‘freeze’ algo choice to the added FX processing desired. Using something like SpaceTime, that’s an extra-versatile approach.
Take the FAST emulation above (instant-on / instant-off), and snap in freeze (via the Parallel VERB LVL and INF DECAY). At the same time, bring up some preset modulation settings and dual bouncing delays by shifting the main MIX. When the Aux Switch is released, everything goes front-and-center with (nearly) 100% dry input.
As a bonus, SpaceTime makes it easy to illustrate the effect routing and switch action. First, with the Aux Switch pressed [expression pedal full toe = freeze + effects]:
Expression Pedal Toe (Aux Switch to EXP PED / HotKnob): MIX 50 VERB LVL Parallel 100 DECAY INF
And when the Aux Switch is released, the freeze buffer gets truncated. MIX stops the mod & time-based effects dead in their tracks. This is the ‘normal’ position of the switch. Input signal is dry, with some pass-through audio from the effects routing.
Expression Pedal Heel (Aux Switch to EXP PED / HotKnob): MIX 0 VERB LVL Parallel 0 DECAY 1/16t
But … that additional effects processing remains active in the background, so it opens up some performance options with the momentary Aux Switch. Double-tapping might bring up a mod+delay emphasis, with nearly inaudible freeze. Active switching overlaps dry input with previously frozen notes and echo. The HotSwitch here is a fail-safe. It snaps MIX 0 at Off to MIX 50 at On, for modulation and delay without freezing. A tap on the Aux Switch resets the HotSwitch latch back to (an equivalent) Off setting.

There’s no perfect way to emulate the SLOW freeze variations in the H9. The DynaVerb algorithm comes closest, with fine control over envelope attack and release times. In the dedicated freeze pedal, the middle SLOW toggle position is shaped offline by the SLOW-SPEED INITIALIZATION procedure:
- TOG1 (Up) Fade-In 200 mS Fade-Out 400 mS
- TOG2 (Middle) Fade-In 200 mS Fade-Out 1.0 S
- TOG3 (Down) Fade-in 800 mS Fade-Out 3.2 S
Expression Pedal Heel: DECAY 20.0 S
Expression Pedal Toe: DECAY FREEZE
HotSwitch Off: GATED
HotSwitch On: OMNI-RATIO INF
Expression Pedal Heel: DECAY 20.0 S
Expression Pedal Toe: DECAY FREEZE
HotSwitch Off: GATED
HotSwitch On: OMNI-RATIO INF
Expression Pedal Heel: DECAY 5.0 S
Expression Pedal Toe: DECAY FREEZE
HotSwitch Off: OMNI-RATIO 0.10
HotSwitch On: OMNI-RATIO INF
These three envelope ‘attack’ shapes will trigger on note input (above the THRESHOLD setting). The freeze will hold until the signal drops below THRESHOLD, then RELEASE over varying lengths of time. For best results, it’s critical to adjust the THRESHOLD level to your input levels & playing style.Here, the Aux Switch -> Expression triggers will operate alongside the automated EG response. The ‘normal’ position will gate or expand on the input-sensitive enveloping. Holding the momentary Aux Switch initiates a long freeze override. HotSwitch is programmed to introduce infinite compression into the mix.

That freeze-type pedal features a LATCH mode: Tap the switch to sample, and the frozen buffer will hold. Tap the switch again, and the buffer is cleared. At that same instant, the sample window opens back up for the next sustained note. In the H9, that’ll mean inverting the switch action over the expression pedal extremes.
For a LATCH emulation, the ‘normal’ Aux Switch position is set to FREEZE. Holding the Aux Switch clears the current note, and releasing the switch samples the next note / chord. Rapid taps will back down the frozen level. For a return to dry input without FREEZE, hold down the Aux Switch for a few seconds (briefly mute your input).

Expression Pedal Toe: DECAY 4.00 S
HotSwitch Off: MOD AMT 0
HotSwitch On: MOD AMT 35
The HotSwitch programming brings in some of that luscious modulation in series with everything else.

Another H9 -exclusive technique combines more than one freeze-pedal feature within the same preset. For example, a hybrid of the LATCH note switch action, along with the SLOW mode envelope shaping. ‘Dynamic reversal’ in the Omnipressor produces some very expressive phrasing, and it’s controlled by your input.
The interaction between FREEZE switching and playing dynamics will blend through auto-accompaniment, latched freeze, small space reverb, and attack / release fades. Create a keyboard or string section background on-the-fly. Loud signals can duck the FREEZE while it sustains underneath. Softer notes will not affect it.
Expression Pedal Heel: DECAY FREEZE
Expression Pedal Toe: DECAY 1.0 S
HotSwitch OFF: LOW-LEVEL 50 HIGH-LEVEL -35 SIDECHAIN IN10 + RV 0
HotSwitch ON: LOW-LEVEL -50 HIGH-LEVEL 75 SIDECHAIN IN 0 + RV10
The HotSwitch remaps equalization, and adds some randomness to the freeze configuration [Ducking defeated].
This next preset introduces dynamics in a different way. It combines freeze latching of an inverse decay reverb, with ‘breathing’ delay loops and resonant shelving filters. Plus everything is bathed in some shallow modulation.
The inverse reverb buildup is ‘sampled’ when you release the Aux Switch (back to FREEZE). So the dynamic level of the frozen signal is determined by exactly when Aux=OFF. Use that to ‘ride’ the freeze levels. FEEDBACK is set to 75 when Aux=ON, so it’ll take a fairly long Aux Switch hold to ‘erase’ the freeze buffer contents.
Expression Pedal Heel: FEEDBACK FREEZE
Expression Pedal Toe: FEEDBACK 75
HotSwitch OFF: PRE-DELAY 2000 mS
HotSwitch ON: PRE-DELAY 20 mS
The HotSwitch drastically cuts the delay time inside the regeneration. This changes the behavior to a more ‘normal’ freeze emulation, with less inversion, looping, and release time. Actually, not all that normal, because all that BLACKHOLE processing creates a monstrous freeze. Use this configuration to make a strong statement.

Man, I’ve been trying to recreate this Brock but when I hit the hotswitch in my app the threshold keeps jumping from -36 to 0 every time. Any tips? Care to share the two freeze/hold presets via email?
Thanks,
Ed
