Polyphonic Limiter
Compresses signals that exceed a specified volume
level, preventing distortion from occurring.
Frequency Shifter
By shifting the frequency relationship of the
fundamental and overtones, a human voice can be
given a “groaning” character.
Lo-Fi Processor
By changing the bit count and sample rate, this effect
recreates the Lo-Fi (Low-Fidelity) sounds of the early
digital samplers and similar machines. After the Lo-Fi
processor, a filter to change the tone is arranged in
series.
