“Just tried it with Gadget in AB and no joy for me.”

“Just tried in AUM earlier and worked great for me 12.9 pro 2017”

“Just ran Pulse through it in AUM.. No issues.. XY worked.. sequencer worked.. no problems.. iPad 2018 running 13.1.2 Edit: Wow! I forgot how cool the sequencer was.. this is still a great FX unit.. 👍“

“It currently doesn't work in AB3, but maybe AB2. I can't remember.”

“MIDI ports don’t seem to work and the visualization screen 100% of the time freezes the app.”


Here are all the new [and old] performance presets that come in the FLUX:FX play app. You can import these into FLUX:FX and have the full set, or edit and then push them back into the iphone app. Options

It's very crude MIDI. Basically just listens for clock and then MIDI messages on the channel you specify. It doesn't send clock like they mention in the manual but I know it was meant to.

Even though abandoned and a few bugs it's still a very solid app overall. I've been using it for years now because it was way ahead of it's time and even now is still way ahead of most apps on iOS.

I'm happy to share some of my presets and any info you need to make it work for you.

Here is all the MIDI control info:

Effect1 = C2 Effect2 = C#2 Effect3 = D2 Effect4 = D#2 Effect5 = E2

Main X/Y pad – The X and Y axis can be mapped to separate MIDI continuous controllers. This also lets you play it with something like the XY from a Korg NanoPad or Keith McMillen SoftStep. TouchDown = C#-1 [This is for the main XY controller to indicate a ‘touch’ as a note] TouchUp = D-1 [This is for the main XY controller to indicate the end of a ‘touch’ as a note] MainXControlNumber = CC1 [This is for the main XY controller to indicate the ‘X’ location] MainYControlNumber = CC2 [This is for the main XY controller to indicate the ‘Y’ location] TouchUpDownControlNumber = CC16 [This is for the main XY controller to indicate a ‘touch’ as a control number]

Input/Output/Mix level – The master levels can be controlled. Ideal for mapping to a volume pedal or slider. InputLevelControlNumber = CC3 [This is for the ‘master input’ level] OutputControlNumber = CC7 [This is for the ‘master output’ level] FXBlendControlNumber = CC4 [This is for the ‘master FX’ blend]

Tempo – FLUX:FX can receive and send MIDI clock messages, allowing you to sync the tempo to another MIDI source such as an external tap tempo, a drum machine or beat app, or a laptop running Ableton, Logic or your favourite DAW. TempoTap = A2 [This sets the tempo after 5 taps]

Sequencer Play/Stop/Record – mappable to allow control and triggering of the sequencer. SequencerTransport [Start/stop] = G2 [This toggles between ‘play’ & ‘pause’ on the sequencer] SequencerRecNoteNumber = G#2 [This switches on or off the ‘record’ function of the sequencer] SmoothingControlNumber = CC5 [This adjusts the ‘step smoothing’ control for the sequencer]

Performances – you can switch performances 1-6 inside the currently selected bank. Performance1 = C1 [This selects performance 1 from the current bank etc] Performance2 = C#1 Performance3 = D1 Performance4 = D#1 Performance5 = E1 Performance6 = F1

It's a good idea to designate MIDI channel 1 to flux as it occasionally defaults to that even though most of the time it will keep your setting.
