Switching File Players in and out using LFOs?
Hi all, and especially @j_liljedahl 
I use Art Kerns’ MIDILFOs to do a lot of semi automated mixing in AUM, but I’ve hit a bump in the road due to what I think is a relatively simple current absence of an addressable parameter in AUM (happy to be advised if there is a work around.)
I use File Player loops a lot, and what I want to do is to automate the manual switching in and out of a running loop you can currently do with your finger using the top ‘input’ swipe.
This leaves the channel fx live, and the loop running, so a reverb trail can mask the abruptness of the switch in and out and keep it sounding coherent, and it drops back in in sync with whatever else was going on before I manually switched it out once I switch it back in.
If I use an lfo to ‘enable’ and ‘disable’ the File Player, this works, but also resets the loop to the start each time. This can be useful, but isn’t what I am looking for here. And if I switch out the output at the bottom of the channel, I obviously lose the whole channel, effects and all.
What I am looking for is a way to automate a manual left swipe of the running loop, whilst retaining the ‘fx trail’ of the live channel, and I think at the moment the available options in AUM don’t let me do this?
All it would take is the addition of a toggle-able ‘Swipe’ button on the ‘channel controls’ section of the AUM bottom of channel dialog that I could address with an LFO.
All thoughts/suggestions appreciated.

Have you tried Auditor’s file player that seems to work slightly different to AUM’s?
Would using an lfo to mute or control the volume of a bus send on a channel with your File Player be a solution? You could setup an FX chain on a channel with the input coming from the send bus. Send the output of any number of File Players to that same bus FX channel. In many respects this is similar to how the MidiMixer app @Stuntman_mike suggested works. If you wanted to insert the FilePlayer output to a specific place in an FX sound chain you could create smaller FX chain bus channels and chain them together.
I see that the file player does not have Bypass, unlike other Generator or Instrument sources. However, @j_liljedahl already got you covered (sort of, like 99%):
Voila!
If 24db attenuation is not enough you can put two gains in series (wired the same way), etc.
Other ways to construct this (now 100%) would be using multiple lanes and forwarding bus sends - which can be Bypass'ed also.
The LFO type used will not matter much, seing that the switch happens at level 64, which gives you a 'duty cycle' of 50% off and 50% on.
So if you want other ratios - especially long running ones - you may want to whip out the sequencer and just note-control the Bypass. You can toogle and/or invert the logic when using notes, I believe.
Keep those creation's going!
I especially enjoy it when you show how you accomplished them in AUM.
Square wave LFO to AUM channel volume will bring parts in and out. But I agree a toggle on and off would be good, so that maybe a sequencer could trigger it.
If you had just the file player on one channel and bussed it to another channel with all the fx, you could then switch out the buss send at the bottom of the file player channel and retain the fx trails on the fx channel. That's how I do it sometimes...
PS Just noticed that this is more or less what @Paulinko suggested in his post above.
Good idea!
The other way I've approached this is to use the file player buss send to effects channel method, but auto pull the send level using the excellent Blueboard Ramper script from @wim in Mozaic. You don't need a Blueboard, any old CC sender will do, and the ramping part of the script means you can automate timed fades of the send channel, in and out...
I'd forgotten; the BB Ramper script can be triggered from midi notes too.
Assuming that you are still sending the player output to a separate mixer lane where you apply your effects, else the channel volume will abruptly stop the effect tails.
Bypassing or modulating a Dynamics -> Gain can be done inline in the same mixer lane.
Yes, @wim and @Wrlds2ndBstGeoshredr - just got to place the effects post-fader. Duhh me - I am so trained to avoid the long tap gesture on the effects, I wiped that out of my repertoire. Channel volume can still be fed from Atom.
AUM example attached, using an Atom "LFO".
One way to do this is to put the FX on a bus send (pre fader). Then muting the file player won't affect the FX tail. The only catch is your FX must have wet/dry control that must be set to 100% wet.
Yes! AUM project with the better way attached.
Another alternative could be using something like MuteMaster by Kai Aras https://apps.apple.com/ar/app/mm-1-mutemaster/id1503359958?l=en , and placing a bus send before it for all the fx and tail
DJ puzzle got you covered with MuteMaster by Numerical Audio
Thanks all for the suggestions, and especially to @Tim6502 for the worked examples of one approach.
@Stuntman_mike : yup, in theory I like the idea of MidiMix, but at the moment, I find it too inflexible and not sufficiently integrated into the AUM mix n match workflow that I love. All I have ever wanted, really, is an editable automation lane for all AUMs interface elements built in, a la Cubasis/Ableton, but @j_liljedahl has made it clear that he never intends to do this, sadly, and midimix currently is only half a solution to this, and probably better for those that take a more structured approach to composition than I do.
I like @wim and @rcf and @Paulinko’s approach the best I think for this particular use case, as these are the cleanest currently available solution. I do already use LFOs for a lot of things, including automated fades via square and random ‘switchers’ and sine wave ’faders’ , and, @audiblevideo @sharifkerbage, I do use MuteMaster, but usually for more general rando madness across the whole mix, as it is too much hassle to set up for a single channel.
I will hold out hope for the feature request for the per-channel ‘switch out’ button, though, pretty please @j_liljedahl (!), as this would allow what I have in mind without having to dedicate a second channel to the task
P.S: any clever dev that could add an editable ‘gesture recorder’ app to AUM, literally, to just record the state and alteration of state of all the on screen elements of the core AUM interface, so that you could mix, then retweak the mix, would be on to a good thing, I think... the editing wouldn’t need a separate interface, or the degree of depth offered in Ableton (though that would be nice!); just allow the ‘red dot’ Ableton method to indicate selected automation targets, and then a ‘live’ overdub, where the recorded mix would play back, and taking hold of a control at any point would ‘overdub’ the new motion or selection as the mix runs. This would allow subtle, iterative, real time playback ‘performance’ editing of an AUM mix... well, I can hope, can’t I?
I haven't said I will never add editable automation lanes in some way, but if editable automation is added then people will want to edit MIDI as well, and then people will want an audio clip arranger as well, etc. I can't promise that such an AUM DAW would never happen, and if it happens I'm not sure in what format (add-on plugin, separate app, separate version of AUM, etc..).
Recallable snapshots that holds state, maybe with interpolation, is something I certainly want to add. Also the per-channel toggle to disable the channel fully (unloading it under the hood).
I was sure that "bypass" was MIDI controllable just as it is for every other kind of node, but it seems not! I'll try to fix that in a coming update.
In the meanwhile, you could add a bus send and automate that (either the send amount or its Bypass) and put the rest of the processing on a second channel receiving on that bus.
@j_liljedahl : Hi, Jonatan, thank you for those observations, apologies if I misrepresented our earlier email exchanges on this - very happy to be corrected
I’m with you in not wanting AUMs’ lean mean miracle of an interface to get over encrusted with DAW doodads, and the release of Atom 2 surely means to a very large extent the midi editing side of things can now be safely offloaded to that little game changer.
I’ve personally always thought of AUM as more of a modular environment that can host other useful and complementary bits and pieces rather than a Swiss Army knife work-in-progress that must eventually have to do everything itself.
So if this automation ‘toolset’ could be envisaged as a bolt on /add in, either as the work of a third party, or as an in-app IAP option offered by yourself, then it would be there for those that could see a use for it, but not getting in the way for those that don’t.
MidiMix is almost right, but is simultaneously too complex and too rigid for my needs. The great joy of AUM is you can add and take away channels, - and all that go with them, in the way of MIDI addressable parameters - as you develop something organically. Something that just extended automation/snapshot/interpolation recording to that, with the same flexibility, on a per channel basis, would be fantastic.
Easy for me to say of course, because I have no tech skills, and can just wish for the moon on a stick without working out how to do that... but still: nothing ventured, nothing gained, right
Also, adding a switch-out button? Great! I’ll make do with the workaround you suggest in the meantime.
As ever though, thanks for literally creating the indispensable space where I am able to make my noises.
