GAMECHANGER AUDIO Auto Series Modular Auto Reverb Pedal

Advanced Reverb Pedal with Patchbay and Parameter Automation

Delve deeply into the wide world of modular reverberation with the Auto Reverb from Gamechanger Audio, a fully modular reverb pedal that allows you to use a built-in CV patchbay to automate decay, level, tone, and drive parameters for completely unique sounds. With switchable plate, spring, and hall reverbs, the sonic potential is vast.

Via the two precise Dynamics and Pitch trackers, you have numerous expressive methods of generating signals for internal or external CV patching. You can select between 0, 50, and 100% stereo spread as well as three Dynamics and Pitch modes. You can also select three Automation modes. LEDs indicate CV signal input or output, and two dedicated LED meters are used to display Dynamics and Pitch signal information in real time. With a plethora of connectivity, including stereo 1/4" inputs and outputs, 3.5mm MIDI and Track inputs, USB-C, and the super versatile 3.5mm patchbay, you can experiment endlessly with external trigger sources, signal chains, electronic ecosystems, and oodles of modular tweaking.

Patchbay and Automation Controls

Each of the pedal's four parameters has a dedicated Automation input socket with a corresponding indication LED, and a mini knob (Auto knob) used for adjusting the amount and direction of the incoming control voltage (CV).

• Automation is achieved by sending a CV into a parameter CV input and adjusting the mini knob
• Two tracker engines are offered: Dynamics and Pitch
• Each tracker has two identical outputs on the patchbay
• Use external CV sources to automate parameters, such as LFOs, sequencers, EGs, and more

• Sum mode: positive CV signals will move the parameter value in the direction the knob is set clockwise, while negative CV signals will move the parameter towards counterclockwise knob positions.
• External mode: allows you to apply the Dynamic or Pitch tracker outputs onto any external CV source to create a variety of ducking and gating effects.
• Alt mode: allows you to use the Auto knobs to set up Alternative parameter values. When the Auto footswitch is engaged, all parameters that have a patch cable inserted will instantly jump to the value dialed in by the Auto knob. 

Dynamics Modes

• Fast mode: fine-tuned to react to strums and sudden note onsets, this mode produces a sharp increase in CV once the threshold is crossed. The Release parameter determines the rate at which the CV value will fall during sustains.
• Rise mode: the Rise mode responds gradually to your playing dynamics and produces a continuous increase in CV whenever the input signal exceeds the threshold value. Release determines the rate at which he CV value will fall.
• Gate mode: this mode is designed to produce rapid on/off automations, jumping to the maximum output value once the threshold is crossed. The Release parameter adjust the duration of the On state.

The Auto Reverb offers you three expansive and precise reproductions of the most frequently used types of reverberation:

• Plate: this algorithm is characterized by slightly metallic and bright overtones typical of studio plate reverbs. The bright overtones can be tamed or exaggerated with the Tone and Filter knobs.
• Spring: with Spring, the algorithm precisely mimics the drippy response of guitar amplifier spring reverb tanks. The tonal response is even more metallic than the Plate reverb.
• Hall: by using the Hall algorithm, you can place your input signal in a physical space, from small reverb chambers to infinitely huge halls. The smooth diffusion can achieve synthesizer pad-type sounds on high Decay settings.

Infinite Decay and Spread

Press and hold both the On and Auto footswitches for infinite decay, which momentarily extends the existing reverb decay into infinite reverb tails. Once you release both footswitches, the reverb tails will decay over the currently set decay time. The Stereo Spread switch determines the reverb width in stereo setups: OFF for mono reverb; 50% for medium stereo spread; 100% for full stereo spread.

• Decay is used to adjust the length of the reverb. The maximum setting produces an infinitely long decay.
• Tone control adjusts the tonal character of the reverb engine on the input stage, mimicking a change in the resonator's physical properties. Adjusting or automating Tone will apply to all incoming signals without affecting the active reverb tails.
• Filter adjusts the reverb engine's output signal. Contrary to the Tone knob, adjusting or automating Filter will boost and/or shave off frequencies from the reverb tails.

Pitch Bar

The Pitch tracking engine analyzes the tonal content of the input signal at all times and displays it as a moving white cursor on the Pitch LED Bar. Depending on the Pitch mode and settings, the cursor will move in and out of CV zones, indicated as red or blue LED segments on the Pitch Bar. The brightness shows output CV strength up to 5V.

• Note mode: using Note mode, you can produce positive CV using any signal note as the reference point.
• Tone mode: rather than tracking specific notes, Tone mode analyzes the input frequency spectrum, allowing you to generate CV based on your instrument's tonal characteristics.
• V/Oct mode: this mode uses the pitch tracker to generate precise bipolar CV output. The calibrated note will produce a 0V output, and notes above or below the calibrated value will produce positive or negative CV output respectively.

Extra Features

• Stereo or mono signal processing via either two 1/4" TS mono cables or one 1/4" TRS stereo cable
• Switchable input level: instrument, line, or Eurorack
• Selectable Level knob functionality: Input Level + Dry Sound, Input Level + Killdry, or Dry/Wet Mix
• MIDI/Clock input for MIDI clock or analog trigger sync for time-based effects
• USB-C for MIDI and updates
