AUTO CHORUS - The AUTO series combines classic pedal design with the world of modular synthesis. Combining classic pedal design with the world of modular synthesis, the AUTO series goes beyond the evolution of audio processing. With every AUTO series instrument, the nuances of your playing become part of the "sound effect" element. Your selections of TOUCH, DYNAMICS, and NOTE affect the sound, creating tones and textures that respond to your playing and change in real time. Sound design through the AUTO series will take your musical expression on a journey of discovery and surprise. Designed for artists seeking their own unique sound, the AUTO series combines intuitive simplicity with depth. Every turn of a knob unlocks a new world of creative and experimental sounds. Dive into the depths of your creativity and discover new sounds that go beyond the ordinary. AUTO CHORUS offers three rich, warm modulation effects: Chorus, Ensemble and Flanger. CHORUS A classic, simple chorus effect that mixes a dry sound with a delay and pitch-shifted signal. For a pure vibrato effect, set the LEVEL KNOB MODE to MIX, the LEVEL knob fully clockwise, and the FEEDBACK knob fully counterclockwise. ENSEMBLE A richer version of Chorus. This algorithm mixes three slightly offset and pitch-shifted signals into the dry signal, making the internal modulation rate less noticeable than with the CHORUS algorithm, even at high DEPTH settings. FLANGE Shortens the delay of the chorus effect, creating a classic jet engine effect. CONTROLS RATE Adjusts the modulation range from 0 Hz to 819.16 Hz. When fully counterclockwise, the pedal stops modulating the delay line and locks in a static delay time controlled by the DEPTH knob. With the RATE set to 0, you can dial in different comb filter sounds with the DEPTH knob. DEPTH Adjusts the modulation depth. The lowest counterclockwise setting has zero modulation depth, which applies a constant, short delay to the wet signal (Chorus and Flanger are delay-based effects). Even with zero modulation depth, you can still use the Feedback control to shape the wet sound. FEEDBACK Adjust the level. Higher settings introduce a metallic, resonant character that depends on the selected algorithm. At maximum settings, the effect enters an infinite feedback loop. TRACK TEMPO AND MODULATION SHAPE AUTO CHORUS takes an innovative approach to tap tempo functionality. TRACK TEMPO If you hold down both footswitches simultaneously, the pedal will use its dynamic tracking feature to detect the tempo of your strumming and set the value of the RATE parameter accordingly. MODULATION SHAPE It offers three different modulation shapes: SAW, SINE, and RAMP. Finding the sweet spot Each of the four main knobs has a corresponding small modulation knob (attenuverter), allowing you to adjust the amount and direction of modulation for each effect knob. This allows you to modulate the value in any direction, + or -, according to the input level. From subtle parameter changes to bold modulation, find your own unique nuances. Customize your modulation with the Dynamics and Pitch knobs and dedicated Mode switch. Adjust the decay time of the dynamics, add glide to the pitch tracking, or shape the response to suit your playing style and desired modulation effect. By pressing both footswitches, you can set the pitch of the played note as the threshold. For example, if you set A3 as the threshold, PITCH modulation will only be active when it exceeds A3. Similarly, you can adjust the threshold for dynamics. Modulation will only occur when the input is louder than the set value. With simple operations, you can create unique modulations as you like. Automation Basics Each pedal features two onboard automation sources that generate automation signals based on specific parameters of your performance. Dynamics engine: follows your instrument's volume, picking strength and overall playing dynamics. Pitch engine: follows the note selection and the overall timbre of the instrument. Using a simple patchbay interface, you can route these automation sources to the four main effect knobs. Each pedal also features four corresponding small knobs (attenuators) that determine the amount and direction of the automation signal. The AUTO footswitch engages the full automation section, allowing you to easily switch from standard effect modes to pre-routed automation settings. For shaping automation, you can precisely calibrate both the dynamics and pitch tracking engines, indicated by LED lights in the patchbay. Additionally, you can customize automation with the dynamics and pitch knobs, as well as dedicated switches with three different modes on either side of the automation, allowing you to tailor the response curve to suit your playing style and desired automation effect. This feature gives you a wide range of touch-sensitive effects that are orchestrated in real time by the nuances of your playing. From subtle and sophisticated settings to ambitious experimental sounds, the AUTO series is a platform offering endless possibilities.IN/OUT - Stereo and mono compatible TS Cable (L/MONO): For mono input (TS) and mono output (TS). Single TS Input to Dual TS Output: Dry input is output to both output channels. Single TS input to stereo TRS output: Dry input is routed to both output channels. TRS Stereo Input (R/TRS): For stereo input to stereo output (TRS). Dual TS or TRS stereo inputs to mono output: Dry input is mixed to the mono output. Calibration and Input Levels Calibrating Center Pitch: Press and hold ON to set the center pitch. Dynamics Threshold Calibration: Press and play AUTO to set a midpoint value. These calibrations are saved until new values are added. Input Level Switch: Varies internal headroom to ensure optimal performance at different signal levels. Output jack follows input level. Can be set to Instrument (4Vpp max), Line (8Vpp max), or Eurorack (12.5Vpp max) level. Dynamics Mode Dynamics Threshold Calibration: Press and play to set the midpoint. FAST mode: Follows the attack of the input signal as soon as it crosses the dynamics threshold. This mode is useful for automation that directly follows the dynamics of a performance. SLOW mode: Gradually follows the dynamics of the performance. This is useful for gradually changing parameter values even when the dynamics of the performance change rapidly. GATE mode: No control signal is output when the input signal is below the dynamics threshold, and maximum control signal is output when the input signal exceeds the threshold. This mode is useful for instantly changing effect parameters without attack or decay times. Pitch Mode Center Pitch Calibration: Press and hold ON to set the center pitch. NOTE Mode: Dials in a control voltage that responds only to a specific note range. With the PITCH knob in the center position, a center-pitch note generates full-strength control voltage, and all other notes generate zero control voltage. V/OCT mode: Depending on the note selection, when you play a note above the center pitch, the automation output generates a positive control voltage. The higher the note, the stronger the control voltage. When you play a center pitch note, the automation output is 0 volts, meaning no automation occurs. TONE mode: Unlike V/OCT and NOTE modes, this mode analyzes the entire frequency spectrum and, instead of detecting exact pitch, detects the overall tone of the input signal and outputs control voltages accordingly. This mode is useful for creating automation based on general pitch ranges and the overall color of the tone. It can detect differences between the neck and bridge pickups on a guitar, or the position of the tone knob. Automation Mode AUTO Footswitch: Activates the entire automation section. PARAMETER AUTOMATION knob: Determines the direction and strength of routed automation. Also acts as an attenuator, allowing fine control over pitch, dynamics, and parameter behavior. SUM mode: The control voltage generated by the automation output is added to the parameter value. The small PARAMETER AUTOMATION knob determines the direction and amount that the control voltage is added to the parameter value. ALT MODE: Changes the function of the small PARAMETER AUTOMATION knob to an alternate parameter value. When the AUTO footswitch is engaged, the small PARAMETER AUTOMATION knob replaces the main parameter knob. EXT MODE: Route an external control voltage signal to automate PARAMETERS and modify them with external modulation signals: DYNAMICS and PITCH. Effect Level IN WET MIX IN mode: The LEVEL knob determines the volume of the signal sent to the effect. The dry signal is always at full volume. WET mode: As in IN mode, the LEVEL knob determines the volume of the signal sent to the effect, but the dry sound is removed from the mix. MIX MODE: The LEVEL knob determines the mix of dry and wet signals: counterclockwise is dry only, center is equal dry and wet signals, clockwise is wet only. AUTO SPLITTER AND TRACKING AUTO SPLITTER: Can be placed at any point in the signal chain to provide a tracking input signal. TRACK IN: Route a clean guitar or other instrument signal for DYNAMICS and PITCH analysis. Effects are applied to the main AUDIO INPUT signal only. TRACK IN is a 3.5mm (1/8'') TRS socket - Track signal insert (L/R) TRACK OUT: Passes the TRACK IN signal through for routing to another AUTO Series pedal or elsewhere. TRACK OUT is a 3.5mm (1/8'') TRS L/R output or track signal buffer output. When TRACK IN is not in use: TRACK OUT outputs the dry mono or stereo AUDIO INPUT. TRACK IN can also be used when nothing is connected to the main AUDIO INPUTS. This is useful for integrating AUTO Series pedals into a Eurorack synthesizer setup without adapter cables.
