Neutron Star

A unique, haunting, crushed and broken reverb based on the OBNE Dark Star.

The original Old Blood Noise Endeavors pedal has a very dark and ambient long reverb going into some unusual stuff like pitch shifters and a bit-crusher. This patch emulates a bit of both modes 1 and 3 of the Dark Star, but in full stereo!

The main effect here is a stereo GhostVerb module, with an optional Pitch Shifter (from -1 to +1 octave) mixed in BEFORE the reverb with the Left Stomp, and 2 Aliaser modules (=Sample Rate Reduction) AFTER the verb with the Right Stomp, which can give a crunchy, broken reverb tail. There are blend controls for both Aliased and Pitch Shifted sides, and there is a pretty slow Slew Limiter for both effects, which makes it very satisfying to turn both sides ON/OFF, as a sort of modulation. Reverb time goes up to infinite and self-oscillation!

=====

[OVERVIEW]
-Input/Output: Stereo in/Stereo out (or Mono in/Stereo out)
-CPU load: Around 84% (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]
2.3: Tested for FW2.0, added Midi CCs, tweaked some control ranges.
2.0: Updated controls, cleaned up routing, removed 1 of the 2 pitch shifters and placed the remaining one before the reverb (much nicer!). Added slew for pitch shift and bit crush. Added EXP functionality.
1.1: Initial patch.

[PATCH STRUCTURE]
PAGE0:
Contains all the main controls (see below).

PAGE1:
Input/Output and an Audio Balance to mix in wet signal.
Ghostverb is here too, the heart of this patch.

I think the CV Expression part is here too. I’ve calibrated it to my own pedal, but it basically just goes into a Value module with a slightly increased connection strength, so that “Toe down” actually reaches 1.000 (and not just 0.9665 or something). Using Exp doesn’t require adjustments but it works sort-off in reverse (Heel Down = action), this is so that when it’s not plugged in, all controls still work.

PAGE2:
Pitch Shifter, 2 Aliasers (L and R) and a bunch of stuff to make the controls work nicely.

[CONTROLS]
All controls are CV Values (Red) on PAGE0:

BAL WET-DRY (Balance between dry/wet, goes fully wet; cc28)
PITCH (Pitch between -1 and +1 octave; cc21)
SAMPLE RATE (Amount of sample rate reduction; higher = more crushed; cc22)
VERB DECAY (Ghostverb decay time; cc23)
VERB RATE (Ghostverb modulation rate; cc24)
PITCH MIX (Balance between clean/shifted signal going into reverb; cc25)
SRR MIX (Balance between clean/crushed reverb tail; cc26)

Not on screen; Ghostverb Resonance (Feel free to adjust, but this really doesn’t like to be turned/modulated, so better to set and forget)

STOMP LEFT = Activates Pitch Shifter, with a nice slew. Always returns to 0 (= center pitch) when deactivated.
STOMP RIGHT = Activates Bit Crusher, with a nice slew. Always returns to 0 (= no bit crushing) when deactivated.
STOMP MIDDLE = Activates/Bypasses whole effect. Only cuts the input, so there are tails!

[FUTURE / IDEAS]
No more changes coming, this was nice, but on to more unique patches and ideas now!

    For those following this: it’s updated!
    This one changed quite a bit (see description for changes), but at least the controls are now named and it works with Expression Pedal! Also made some quick demos. Enjoy!

    Picture manual attached!
