Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Best way to blend FX live?
I'm playing guitar for a show this weekend and I've been using AUM as essentially a pedalboard. What I do is have a clean channel with a bunch of FX sends, and then each of those is on a bus to the master, where I have some EQ and compression.
The way I want to do it is be able to change and mix the amount of each effect that is coming through, like right now I want a ton of reverb, a little crunch, a little delay, and the next moment I want filter, fuzz, crunch, more delay, less reverb.
This works okay if I'm just playing around at home and can stop what I'm doing to get everything leveled. The problem I'm running into is that if the totally clean channel has enough volume, as soon as I start adding the FX channels in I clip to high goddamn heaven.
I know I should be working in chain and not in parallel to avoid this, but then I can't really control the blend of FX. Also, I have 6 faders and 6 buttons available on stage, and if I map the wet/dry plus the level of all the effects, I'm out of controls pretty quick. Also, not all the effects I'll be using have a wet/dry or a bypass, so if I lessen the effect in the chain, it cuts the volume for everything downstream. For instance, I have a pedal emulation that has gain, treble, and volume knobs only. I have a tone that I want out of it using a combination of gain and volume, but there's no way for me to effect how much clean signal gets through. Any signal going through it is colored in some way.
The only thing I can think of is basically setting it up as a chain, but somehow the volume fader on the track is just controlling how much of the clean signal is getting pulled into that tracks FX? I think this might be possible by putting a bus send pre-fader, but I'm having issues imagining the signal flow.
I don't know if I'm thinking about this all the wrong way but I would think this HAS to be possible, the Grateful Dead had super complex FX mixes set up in like 1974 without clipping.
Help me, Audio Kenobi, you're my only hope.
