Real-time Control of Riff Parameters

You can have real-time control over several Riff parameters, by assigning physical controllers to
special Riff Controller Destinations. Any input (or entry value) from a physical controller
assigned to a Riff Controller Destination overrides the programmed values for the parameters of
the riff on that controller's zone. The override remains in effect until you select a different setup.
Remember, each of the following Controller Destinations affects only the riff for the zone which
your controller is assigned to.

Riff Parameter
RiffOn
Riff On. Any value triggers the zone's Riff if Riff is set to On on
RIFF1 page.
RiffOff
Riff Off. Any value stops playback of zone's Riff.
RiffDur
Riff Duration, sets the Duration parameter (see above.) The
Duration value is calculated by multiplying the received
controller value by 1000, and dividing the answer by 128 (any
decimal points are taken off the final value.) Here are some
example values: 7 = 54%, 13 = 101%,19 = 148%, 32 = 250%,
64 = 500%, 127 = 992%
RiffVel
Riff Velocity, sets the Velocity parameter (see above.) The
Velocity value is calculated by multiplying the received
controller value by 2. For Example, 25 = 50%, 50 = 100%, 100
= 200%, 127 = 254%.
RiffDly
Riff Delay, Controls Offset parameter (see above.) Controller
value 64 = 0 offset ticks. Each value away from 64 = 512
offset ticks. For example, 63 = -512 offset ticks, 65 = +512
offset ticks, 0 = -32768 offset ticks, 127 = +32256 offset ticks.
