962 Tremolo BPM

A stereo tremolo or auto-balance effect
PAUs: 1
Tremolo and Tremolo BPM are 1 processing allocation unit (PAU) stereo tremolo effects. In the classical
sense, a tremolo is the rapid repetition of a single note created by an instrument. Early music synthesists
imitated this by using an LFO to modulate the amplitude of a tone. This is the same concept as amplitude
modulation, except that a tremolo usually implies that the modulation rate is much slower.
Tremolo and Tremolo BPM provide six different LFO shapes (Figure 2), an additional shape modiÞer
called Ò50% WeightÓ, ÒL/R PhaseÓ for auto-balancing, and LFO metering. L/R Phase ßips the LFO phase
of the left channel for auto-balancing applications. The 50% Weight parameter bends the LFO shape up or
down relative to itÕs -6dB point (Figure 1). At 0dB, there is no change to the LFO shape. Positive values will
bend the LFO up towards unity, while negative values will bend it down towards full attenuation.
Additionally, LFO metering can be viewed on the bottom of PARAM2 page.
Tremolo also includes an LFO rate scale for AM synthesis, and Tremolo BPM provides tempo based LFO
syncing including system syncing.
