FabFilter Volcano 3 is available as an AUv3 plug-in for iPad in the App Store.
Using Volcano 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.
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 Volcano 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 Volcano 3's features.
