FabFilter Pro-Q 3 is available as an AUv3 plug-in for iPad in the App Store.
Using Pro-Q 3 on a touch screen is slightly different from using it with a mouse:
To adjust a knob, just touch it and drag up or down.
There is no rotational drag mode like with the mouse.
For fine adjustment, hold down a second finger while you're dragging a knob.
To reset a knob to its default position, simply double-tap it.
To type a new value directly, press and hold on a knob until the
on-screen keyboard appears. Note that the keyboard might obscure the parameter value
display — unfortunately we can't do anything about that because an AUv3 plug-in cannot
control its own position on the screen.
In the EQ display:
Drag the result curve, or double-tap on the display background to create a new band.
You can just drag bands with your finger. To select multiple bands,
draw a rectangle around them by starting a drag on the display background.
For fine adjustment, hold down a second finger just like with knobs.
Double-tap and drag to adjust the Q of a band.
You can directly type a new value for one the the band's parameters by
pressing and holding down on the parameter value in the EQ parameter display.
To open a pop-up menu with all parameters for a band, press and hold down
on the band's control point until the menu appears. You can also tap the small
menu button on the right side of the EQ parameter display.
To delete the selected bands, just tap the small X button on the
right side of the EQ parameter display.
To enter Spectrum Grab mode, press and hold on
the spectrum area until it turns blue.
In most host apps, the AUv3 plug-in version of Pro-Q 3 opens at the default interface
size for AUv3 plug-ins, which is quite small and doesn't have enough space to show
the band controls. You can fully use all of Pro-Q 3's
features directly from the EQ display and the pop-up menu, but we recommend to use
a host app that offers resizing for the best user experience, such as AUM, Auria, or
n-Track Pro.
Unlike the regular plug-in, the AUv3 plug-in offers no resizing or full
screen mode from the plug-in interface itself: this must be provided by the host app.
To organize presets on iOS, open the preset menu
and swipe to the left on any preset or subfolder to see options to delete or edit it. When
editing a preset or folder, you can rename it and move it to another folder.
The Pro-Q 3 app that contains the AUv3 plug-in serves as a stand-alone host that
simply routes audio from the microphone to the plug-in and plays it back in real-time
via the speakers or headphone output. You need to manually start the audio engine using
the Audio On/Off switch at the bottom, but first make sure that the speaker volume is
not too high to avoid excessive feedback!
We do recommend to use an AUv3 host
app like Auria, Cubasis, AUM or GarageBand to take full advantage of Pro-Q 3's features.
