Controls and Operation
The INIFINITE MINI SAMPLE SUSTAINER pedal features intuitive controls for shaping your sustained sounds:
- LEVEL Knob: Controls the overall output volume of the sustained signal. Adjust to balance the effect with your dry signal.
- FADE IN Knob: Determines the speed at which the sustained sound fades in after activation. Turn clockwise for a slower, more gradual fade-in.
- DECAY Knob: Controls the rate at which the sustained sound fades out after the footswitch is released (in momentary mode) or deactivated (in latching mode). Turn clockwise for a longer decay time.
- Footswitch: This multi-functional footswitch controls the activation and behavior of the sustain effect. It supports both latching and momentary modes, and features MASH technology for expressive control.
Operating Modes:
- Latching Mode: Press and release the footswitch to activate the sustain effect. The effect remains active until you press and release the footswitch again.
- Momentary Mode: Press and hold the footswitch to activate the sustain effect. The effect remains active only while the footswitch is held down, disengaging upon release.
- MASH Functionality: In momentary mode, pressing harder on the footswitch (MASH) can introduce additional expressive control over the effect, depending on the TonePrint loaded.
- Infinite Mode: This mode allows for layering multiple sustained sounds, creating rich, evolving soundscapes. Each new sustained note or chord will blend with the previous layers.
TonePrint App Connectivity:
The INIFINITE MINI SAMPLE SUSTAINER pedal is TonePrint enabled. Connect your pedal to the TonePrint app (available for iOS and Android) via USB to access a vast library of custom-tuned effects created by world-renowned artists, or to design your own unique TonePrints by adjusting an expanded array of parameters.
