Rave Generation Filterbank v1.0.2 (Win/macOS)

Filterbank is the result of extensive research into analog circuit behavior, capturing the subtle non-linearities, component interactions, and distinctive characteristics that make hardware filters so coveted. Whether you're crafting experimental soundscapes, adding movement to static sounds, or bringing aggressive character to your mix, Filterbank provides the tools to elevate your productions with authentic analog warmth and character.

Full MIDI CC compatibility with specialized note triggering system for live performance and sequenced modulation.
USER INTERFACE - MAIN CONTROLS
Top row controls
INPUT: Controls the input gain and drive into the filter system. Higher settings introduce analog-style saturation and harmonic enhancement at the input stage, significantly affecting the overall character of the processing.
FM (Frequency Modulation): Adjusts the amount of frequency modulation applied to both filters, allowing for complex timbral changes, sideband generation, and aggressive sonic transformations.
ADSR controls: The central ADSR section includes:
A (Attack): Controls the attack phase of the ADSR envelope, determining how quickly the modulation rises when triggered.
D (Decay): Sets the time for the ADSR envelope to fall from peak to sustain level after the attack phase completes.
S (Sustain): Determines the held level of the ADSR envelope while the trigger remains active.
R (Release): Controls how long the ADSR envelope takes to return to zero after the trigger ends.
SPEED: Controls the frequency of the LFO from extremely slow modulation through typical LFO rates to audio-rate modulation, enabling both subtle movement and FM-like effects.
DEPTH: A bipolar control for LFO intensity. Center position provides no modulation, while turning right or left increases the modulation depth in different phase relationships, allowing complementary modulation of both filters.
AM (Amplitude modulation): Controls the depth of amplitude modulation, creating tremolo, ring-modulation, and gating effects depending on settings.
PAR<>SER: Controls the routing of the dual filter system. Fully left (PAR) processes audio through both filters in parallel, while fully right (SER) routes the output of Filter 1 into Filter 2 for serial processing. Intermediate settings blend between these configurations.
BYP<>EFF: Controls the balance between the bypassed (dry) and processed (wet) signals. At center position, both signals are mixed equally, while fully left bypasses all processing, and fully right applies 100% effect.
Switch controls
HI BOOST/HI CUT/NORMAL: A three-position switch that controls pre-filter equalization. HI BOOST enhances high frequencies before filtering for added brightness, NORMAL maintains a neutral frequency response, and HI CUT reduces high frequencies for a warmer character.
SENSITRIG/NORMAL/LIMIT: A three-position switch controlling the trigger sensitivity for both AR and ADSR envelopes:
SENSITRIG: Increases trigger sensitivity for better response to quiet sources
NORMAL: Standard trigger sensitivity for most audio material
LIMIT: Reduces sensitivity to prevent false triggering with complex material
+OCTAVE/NORMAL/+QUINT: A three-position switch for harmonic enhancement:
+OCTAVE: Raises filter frequencies by one octave
NORMAL: No transposition
+QUINT: Introduces a unique quint (fifth) transposition that adds harmonic complexity
TRACK/NORMAL/TRACK LOW: Controls the pitch tracking function:
TRACK: Dynamically adjusts filter frequencies based on the detected pitch of the input
NORMAL: Disables pitch tracking
TRACK LOW: Similar to TRACK but targets lower frequencies, ideal for bass material
Filter controls
FREQ 1: Sets the cutoff frequency for Filter 1. This exponential control provides fine adjustment in the critical lower frequencies while allowing quick access to the full frequency spectrum.
RESO 1: Adjusts the resonance feedback for Filter 1. Higher settings emphasize frequencies near the cutoff point, creating peaks that can range from subtle enhancement to extreme self-oscillation.
LBH 1: A bipolar control that smoothly blends between lowpass (fully left), bandpass (center), and highpass (fully right) responses for Filter 1.
BLH 1: A sophisticated correction control that modifies the filter response by adding or subtracting filter components. At center position (0), no correction is applied. Moving left (-B) reduces bandpass presence, while moving right (-B+LH) adds lowpass and highpass components to the bandpass.
HARMONICS: A 12-position rotary switch that defines the harmonic relationship between Filter 1 and Filter 2. "FREE" allows independent control, while the numbered positions lock Filter 2 to specific musical intervals relative to Filter 1.
FREQ 2: Sets the cutoff frequency for Filter 2. When HARMONICS is active, this control is subordinate to FREQ 1 according to the selected harmonic relationship.
RESO 2: Controls the resonance for Filter 2 with a slightly different character than RESO 1, allowing complementary tonal shaping when both filters are used together.
LBH 2: Provides the same filter type control as LBH 1 but for Filter 2, enabling complex dual-filter configurations.
BLH 2: Provides the same correction functionality as BLH 1 but for Filter 2.
Envelope and trigger controls
AR TRIG: Selects the trigger source for the AR envelope:
OFF: No external triggering (manual control only)
SIDECHAIN: Uses audio from the sidechain input for triggering
MIDI: Allows MIDI notes to trigger the AR envelope
A (Attack): Controls the attack time for the AR amplitude envelope, shaping how quickly the processed signal reaches full volume.
R (Release): Sets the release time for the AR envelope, determining how the processed signal fades out when the trigger ends.
Bottom panel controls
DIST TYPE: Choose between different distortion modes:
CLEAN: Minimal distortion with subtle enhancement
WARM: Analog-inspired saturation with even harmonic emphasis
CRUNCH: More aggressive distortion with complex harmonic content
EDGE: Maximum distortion with pronounced frequency-dependent character
TRIG ADSR: Selects the trigger source for the ADSR envelope.
OFF: No external triggering (manual control only)
SIDECHAIN: Uses audio from the sidechain input for triggering
MIDI: Allows MIDI notes to trigger the ADSR envelope
TRIG AR: Selects the trigger source for the AR envelope.
OFF: No external triggering (manual control only)
SIDECHAIN: Uses audio from the sidechain input for triggering
MIDI: Allows MIDI notes to trigger the AR envelope
ADSR SENS: Controls the audio threshold level (in dB) for ADSR triggering. Adjust this to fine-tune how the ADSR responds to your audio material.
AR SENS: Controls the audio threshold level (in dB) at which the AR envelope will trigger when using audio input as a trigger source. Lower values make the AR more sensitive to quiet sounds.
THD DRIFT: Controls the amount of thermal drift simulation, affecting how the distortion characteristics subtly change over time. Higher settings create more pronounced "breathing" effects typical of analog hardware.
NOISE: Introduces calibrated pink noise into the signal path, useful for adding texture, creating ambient atmospheres, or enhancing percussive elements.
LFO SYNC: Synchronizes the LFO frequency to your DAW's tempo with various rhythmic divisions (1/1, 1/2, 1/4, etc.), ensuring perfectly timed filter modulation.
OUTPUT: Adjusts the final output gain after all processing. This compensates for level changes introduced by filtering and distortion.
Additional controls
LFO MODE: A three-position switch selecting between RESTART (LFO restarts with each new trigger), NORMAL (standard sine wave modulation), and SAWTOOTH (changing the LFO waveform from sine to sawtooth for different modulation characteristics).
ADSR MODE: A three-position switch selecting between:
ADSR: Standard envelope generator mode with full ADSR control
FREEZE: Sustains the current envelope state regardless of trigger input
ENVELOPE FOLLOWER: Dynamically tracks the amplitude of the input signal
OVERSAMPLE: Toggles between standard processing and 4x oversampling. When enabled, this significantly reduces aliasing artifacts, particularly with high resonance settings and upper-frequency content, at the cost of increased CPU usage.
