Neutron Star

Neutron Star!

An highly-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 modes 1 and 3 of the Dark Star, but in full stereo:

Mode 1 has a stereo GhostVerb module going into 2 pitch shifters, both ranging from 1 oct down to 1 oct up. One is panned left, one panned right.

Mode 2 has 1 pitch shifter after the reverb, then goes into an Aliaser (which is a sort-of sample-rate-reducer). The Aliased sound and the clean Pitch Shifted sound are blended at the output. Output is stereo, but due to CPU limits there’s only 1 Aliaser shared between L+R output.

Mix goes 100% wet, and dry signal passes through in full stereo.
Reverb time goes up to infinite and self-oscillation.
CPU load = around 100%. Built with Firmware V1.0
Patch is inspired by John B. from ZOIA facebook group, and uploaded by request (have fun Brock!) and is now more-or-less finished! It now has smoother controls, and is slewed so changing settings is smoother. No CPU room for much more stuff though, so no EXP added.

All the controls are here now.

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

2 Pitch Shifters (L and R), 2 Aliasers (L & R) and a bunch of switches to make sure the controls work nicely in both modes. Only the reverb tails get shifted/crushed.


All controls are CV Values (Red) on PAGE0:

TOP LEFT = CTRL1 (Sets pitch shifter in both modes)
TOP RIGHT = CTRL2 (Sets 2nd pitch shifter in mode 1, or rate [in Hz] of sample-reduction in mode 2)
BOTTOM LEFT = MIX (dry/wet, goes fully wet for extraterrestrial ambience)
BOTTOM RIGHT = REVERB (Length of reverb tails + feeback, goes up to self-oscillation)

STOMP LEFT = switches between Mode 1 (dual Pitch Shifter) or Mode 2 (Pitch Shift into Aliaser/Bit Crusher)

It’s pretty much done as of now.
Maybe something creative could be done with the stereo field, and EXP would be nice, but it starts clipping if I try to add anything more…
