The LFO speed of all modulation effects is controlled by the PARAMETER control. EFFECT A controls the effect intensity or depth. High values produce a very intensive effect. In the case of the tremolo algorithm, EFFECT A adjusts the panning between left and right, and vice versa.
+In the stereo modulation effects (programs 36/37, 50/51, 62/63), the left and right channels are modulated in reverse phase, which can partly eliminate the effect when reproduced in mono. In particular, the tremolo will be inaudible if high stereo panning values are used in mono via the built-in speaker. In this case, it will be better to use no panning at all (EFFECT A = 0).
30-33 Phaser: From a technical point of view, phasing is a modulation effect producing a multi-stage phase shift between direct and effect signals. As the frequency-dependent phase shift is controlled by an LFO (low-frequency oscillator), the various frequency ranges of the signal are raised or lowered in their amplitudes. Depending on the setting you choose, the resulting phasing effect is either slightly modulating in character or produces heavy sound coloration reminiscent of a continuously modulated filter.

34-37 Chorus: Imagine a string quartet, with each musician playing the same notes. As a matter of fact though, no musician is able to play with an intonation accuracy of 100%. Consequently, slightly detuned signal portions are produced which overlap in the time domain. To emulate this effect, chorusing uses copies of the original signal, which are then delayed by 20 to 40 msec, detuned slightly and modulated by the LFO. The result is a detune effect that is very pleasant in character. As this effect is used so frequently and in such a variety of signal-widening applications, any recommendation given here would mean a restriction of its uses.

38-42 Chorus/Reverb: Here, the signal passes a chorus effect with various intensities and then a reverb that can be edited in time.
