2. Choose a modulation source from the mod pop-up menu.
Off: Deactivates the mod routing, and the mod control can no longer be adjusted.
In this situation, no via modulation can occur either, because via no longer has a
modulation target, and the via control disappears.
Lfo1-Lfo2: Choose one of the LFOs (low frequency oscillators) as the modulation
source.
Env1-Env4: Choose one of the envelope generators as the modulation source.
Max: Produces a static modulation at maximum level. When the mod value is set to
Max, the via parameter is routed directly to the modulation target. Velocity can then
be used as a direct modulation source, even though Vel is not available as a source
in the mod pop-up menu.
Tip: You can also set up an external MIDI fader unit with CtrlA, B, C, or D. Use the
Max menu item to route a via source—CtrlA, B, C, or D—to the parameter you want
to control with a fader on your MIDI fader device.
3. If you want to assign a via source, choose one of the following from the via pop-up
menu.
Vel: Velocity is used as the via modulation source.
CtrlA to CtrlD: Choose one of these continuous controllers that can be assigned to
four external MIDI controllers. These assignments apply to all sounds in the current
Ultrabeat plug-in instance. See Assign Logic Pro Ultrabeat MIDI controllers.
4. Adjust the mod and via controls.
