A cinematic, deconstructed space effect.

24 HP Eurorack module

A stereo, deconstructed spatial reverb that exposes diffusion, delay, tail, pitch placement, mixing, freezing, and envelope tracking as independently adjustable regions.

Features

Deconstructed reverb with more than 40 delay lines, separate diffusion, delay, and tail regions.
Stereo output is retained when using a mono input.
Delay and tail can be frozen independently or together; frozen regions stop accepting new audio.
Three stereo pitch shifters can operate at seven selectable locations in the signal path.
MIDI note control supports monophonic Regular and Free operation or the first three held notes in Chord mode; MIDI clock is ignored.
An envelope follower provides regular or inverted ducking CV derived from the dry input.

Controls & Jacks (60)

Send/Mix— Toggles Main Mix between Send behavior when illuminated and wet/dry crossfade behavior when unlit.
Free Mode— Lights when Free mode is selected, providing unquantized monophonic transposition with symmetrical detuning.
Delay Length— Sets the base delay time in Pingpong and Multitap modes or the virtual pipe length and resulting pitch in Waveguide mode, from extremely sho
Transpose— Transposes the center pitch of the shifters across ±24 semitones; the Pitch Mode control blinks at exact -24, -12, 0, +12, and +24 semitone
MIDI Input— Receives MIDI notes for the pitch shifters; Regular and Free follow the latest note, while Chord responds to the first three held notes. MID
Audio Input 1— First stereo audio input, routed through the processing line to Audio Output 1; it may also be used alone for mono input.
Chord Mode— Lights when Chord mode is selected, assigning the three shifters different notes from the chosen or MIDI-supplied chord.
Audio Output 1— First channel of the stereo processed output, corresponding to Audio Input 1.
Transpose CV Input— Controls the pitch shifter's central transposition over approximately ±24 semitones with roughly 1 V/octave response.
Tap Input— Accepts gates or clock pulses that establish the base delay tempo, equivalent to tapping the Tap control.
Freeze— Holds the selected delay and/or tail audio indefinitely and prevents those frozen regions from accepting new input while held.
Pitch Mode— Cycles the pitch shifters among Regular quantized monophonic, Chord polyphonic, and Free unquantized modes; changing mode also clears a hang
Flavour— Morphs the all-pass diffuser's timing ratios from close and immediate reflections to increasingly distant spatial impressions.
Control CV Input— Adds an external control voltage to Pitch Control; its effect follows the selected Regular, Chord, or Free pitch mode.
Audio Output 2 Activity— Blinks in response to audio present at Audio Output 2.
Feedback CV Input— Adds an external control voltage to the Feedback setting; the expected range is -5 V to +5 V.
Tail Level— Sets how much of the reverb-tail region is applied along the signal path.
Tail Length— Sets the decay time for all tail algorithms, from extremely short to nearly infinite; in Sparse mode it also spaces the granular events fart
Main CV Input— Adds an external control voltage to the Main Mix setting; the expected range is -5 V to +5 V.
Tail Mode— Cycles the reverb-tail algorithm among Dense, Float, and Sparse.
Pitch Point Output— Lights when pitch shifting is placed at the end of the processing line.
Temperature— Applies a warm-to-cold tilt filter in Dense and Sparse, or balances damping against octave shimmer in Float.
Pitch Point Dry Mix— Lights when pitch shifting is applied to the dry-mix path.
Multitap Mode— Lights when Multitap delay is selected, producing three stereo taps with predetermined time ratios, positions, and levels.
Tail Length CV Input— Adds an external control voltage to the Tail Length setting; the expected range is -5 V to +5 V.
Delay Length CV Input— Adds an external control voltage to the Delay Length setting; the expected range is -5 V to +5 V.
Envelope Output— Outputs a preprocessed regular or inverted ducking envelope derived from the dry input, with a maximum level of 5 V.
Freeze Gate Input— Freezes the enabled delay and/or tail regions while an external gate is held high.
Audio Input 1 Activity— Blinks in response to audio present at Audio Input 1.
Temperature CV Input— Adds an external control voltage to the Temperature setting; the expected range is -5 V to +5 V.
Delay Mode— Cycles the delay algorithm among Pingpong, Waveguide, and Multitap.
Audio Output 2— Second channel of the stereo processed output, corresponding to Audio Input 2; the output remains stereo when only one input is used.
Audio Input 2— Second stereo audio input, routed through the processing line to Audio Output 2.
Pitch Point— Moves the pitch-shifting stage among seven positions in the audio path: start, diffuse, delay, delay feedback, tail, end, and dry mix.
Audio Input 2 Activity— Blinks in response to audio present at Audio Input 2.
Main— In Send mode, moves from dry input to dry plus wet effects; in Mix mode, crossfades from dry to wet; in the alternate always-dry mode, sets
Feedback— Sets how much processed signal returns to the beginning of the delay, from maximum decay to near-infinite feedback.
Audio Output 1 Activity— Blinks in response to audio present at Audio Output 1.
Delay Level— Sets how much of the delay region is applied along the signal path.
Pingpong Mode— Lights when Pingpong delay is selected, with echoes alternating across the stereo field.
Waveguide Mode— Lights when Waveguide delay is selected, creating a short resonant pipe-like physical-modeling effect.
Regular Mode— Lights when Regular mode is selected, placing all three shifters near the same quantized monophonic pitch.
Envelope Level Indicator— Shows the Envelope Output voltage: full brightness represents 5 V, lower brightness represents a smaller voltage, and darkness represents 0
Sparse Mode— Lights when the minimal granular Sparse tail with reordered forward and reverse fragments is selected.
Envelope— Selects an inverted ducking envelope to the left or a regular envelope to the right; the center produces no output, and the extremes add a s
Pitch Point Start— Lights when pitch shifting is placed at the start of the processing line.
Tap— Tap repeatedly to establish the delay tempo; its embedded illumination blinks at the active tempo.
Pitch Point Delay— Lights when pitch shifting is placed at the input to the delay region.
Pattern— Changes the stereo delay-time relationship in Pingpong, selects the frequencies retained in Waveguide, or applies a warm-to-cold tilt filter
Delay Activity— Blinks with the audio activity and intensity passing through the delay region.
Chorality— Adds detuned voices in Dense, applies subtler chorusing in Float, or sets the probability of granular events in Sparse.
Pitch Point Diffuse— Lights when pitch shifting is placed at the input to the diffuse region.
Pitch Point Feedback— Lights when pitch shifting is placed within the delay feedback path.
Diffuse Activity— Blinks with the audio activity and intensity passing through the diffuse region.
Diffuse Level— Sets how much diffusion is applied at the corresponding region of the signal path.
Control— Sets portamento in Regular mode, selects a chord voicing in Chord mode, or symmetrically detunes the three shifters by up to an octave in Fr
Dense Mode— Lights when the full, highly diffused Dense tail algorithm is selected.
Float Mode— Lights when the smooth, ethereal Float tail with octave shimmer is selected.
Tail Activity— Blinks with the audio activity and intensity passing through the tail region.
Pitch Point Tail— Lights when pitch shifting is placed at the input to the tail region.
