Disaster Recovery SR

A dark modulated delay and murky reverberation machine based on the EQD Disaster Transport SR.

I’ve always liked the Disaster Transport SR’s general idea: 2 delays in one pedal with the ability to run them in series, parallel, or a mix of both. However, I never got one because of the substantial analog hiss and noise in the sound. It’s got character, which is good SOMETIMES… but not always, so I never got one.

So… here is the Disaster Recovery SR: Similar delays, similar routing, similar knobs, longer delay times, and fully in stereo! Yay!

=====

[OVERVIEW]
-Input/Output: Stereo in/Stereo out (or Mono in/Stereo out)
-CPU load: Around 78% (with Firmware 2.0)
-Build: Updated with firmware 1.13
-MIDI: Controls are set to CCs (I use channels 21/36, see CONTROLS section for details).

[REVISIONS]
2.1: Tested for FW2.0 and added Midi CCs.
2.0: Updated controls, cleaned up routing. Changed Bleed routing (can now be before or after reverb).
1.1: Initial patch.

[PATCH STRUCTURE]
Audio in also goes to 2 delays enabled with Left and Right stomp switches respectively.
Delay A (left controls) is a dark, dirty, modulated tape delay.
Delay B (right controls) is a shorter, slightly cleaner delay with a reverb at the front.
They can be run in parallel (turn on both) or series (turn on Bleed and delay A), or a mix of both.

PAGE0:
Contains all the main controls (see below).

PAGE1:
Contains input/output, VCAs and Stomp switch modules for routing audio to the Delays, and output module with gain.

PAGE2:
Contains Delay A; the Modulated delay module, set to ‘dirty tape’ mode. Delay time ranges from about 60ms to 1200ms. Output goes to a mixer for Delay A “wet” level, and to a mixer for “bleed” level, which sends it to Delay B (either before or after the reverb).

PAGE3:
Contains Delay B; first a plate reverb (not sure if this is closest to the EQD one though!) going into another Modulated delay module, set to ‘clean tape’ mode. Delay time from around 60ms to 400ms. Output goes to a mixer for Delay B “wet” level.

=====

[CONTROLS]
White controls are DRY MIX at the top (turn to 0% for ambient droney things), and a BLEED PRE-POST VERB toggle at the bottom (sets whether A bleeds directly into delay B or through the reverb first).

DELAY A – Left side in RED:

MIX A (sets level of delay A wet signal; 25)
TIME A (sets delay time ~60ms to 1200ms; cc21)
REPEATS A (sets feedback; oscillates nastily at higher settings; cc22)
MOD DEPTH A (sets modulation depth; cc29)
MOD RATE A (sets modulation rate; cc30)

DELAY B – Right side in MAGENTA:

MIX B (sets level of delay B wet signal; cc27)
TIME B (sets delay time ~60ms to 500ms; cc23)
REPEATS B (sets feedback; oscillates at higher settings; cc24)
VERB MIX B (sets reverb level; slightly increases reverb time at higher settings; cc28)
VERB DECAY B (sets reverb decay time; cc31)

MIX DRY (sets level of dry signal; cc32)
BLEED A-B (sets % of wet signal from delay A sent into delay B; cc26)
BLEED PRE-POST VERB (toggles if bleed signal enter before/after the reverb of delay B)

LEFT stomp = Activates Delay A.
RIGHT stomp = Activates Delay B.
MIDDLE stomp = Activates Bleed.

[ROUTING]
For Parallel routing, turn on A and B, set BLEED to 0.
For Series routing, turn A on and B off, set BLEED to 100% (Delay B is still active, but receives no direct input, only from BLEED).
For a mix of both, turn on A and B, set MIX A, MIX B and BLEED to taste.
For only Delay A, don’t forget to turn BLEED off (middle stomp).

[FUTURE / IDEAS]
The EXPRESSION pedal isn’t assigned yet, might be nice to have.
Also there’s no LED speed for delay time indicators (like in the original, which only has a Modulation Rate LED), but that’s tricky since it’s built with the built-in effects modules).

Enjoy! And feel free to comment or suggest improvements!

    For those following this: it’s updated!
    Named all the Values/knobs on the front page, new layout of knobs, cleaned up some routing, and added some small things (Middle stomp turns Bleed on/off, Bleed can go pre/post the reverb, and Dry can be turned to 0%). Enjoy!

    Picture manual attached!

    Sounds really good, can’t wait to try this one!
