Reference
XOVR (Bass Crossover) 0.1 - 26.5kHz
XOVR sets the frequency at which the transition from RTIM to BASS takes place. XOVR should
be set at least two octaves higher than the low frequency you want to boost. For example, to
boost a signal at 100 Hz, set XOVR to 400 Hz (This setting works well for classical music). XOVR
works best around 400 for boosting low frequencies, and around 1.5 kHz for cutting low
frequencies.
BASS (Bass Multiply)
BASS sets the reverb time for low-frequency signals, as a multiplier of the RTIM parameter. For
example, if BASS is set to 2X, and RTIM is set to two seconds, the low frequency reverb time
will be four seconds. For a natural-sounding hall ambience, we recommend values of 1.5X or
less.
TDCY (Treble Decay)
TDCY sets the frequency above which sounds decay at a progressively faster rate. It filters all
the sound except the pre-echoes. When set relatively low, it gives a darker tone to the
reverberation, simulating the effect of air absorption in a real hall. TDCY also helps keep the
ambience generated by the effect from muddying the direct sound.
LINK
When LINK is set, the reverb time and spread values scale linearly as the SIZE control is varied.
For some special effects, RTIM and SPRD can be unlinked.
SPIN (Randomization)
SPIN affects the rate of change of the timbre. The object of SPIN (and WAND) is to
continuously alter the timbre of the reverberant sound. This makes the result more natural,
without making the position of instruments unstable. SPIN should typically be 20 or higher.
High values may make the pitch of piano or guitar unstable.
WAND (Wander)0µs - 37.1ms
WAND sets the distance in time that the reverb tail will move relative to the rate of SPIN. For
best results WAND should be about 10ms at larger sizes.
