LFO Generator Runs INDEPENDENT of Host
HI,
Is there an LFO generator like Rozetta LFO that will run without or fully independent of the "play" button or function of the host?
So in other words, in AUM or in Loopy Pro whether play or the host is running or NOT, the LFO still runs. Rozetta LFO has a switch that "suggests" it can independently from the host. The switch is called "Temp Sync". But if the switch is on or off it doesn't matter. As soon as you stop the host from running. The LFO stops 
I need to generate MIDI CC messages based on an LFO and need to do that fully independent of the host play or running.
Thanks!!

mLFO is top notch can sync or run independently. On sale too
You know… I have to double check on that specifically.
I believe "Temp Sync" just makes the LFO rate a multiple of the host tempo setting. Just a different way of setting the parameter.
@uncledave When I run Rozetta LFO, and switch tempo sync off, the little visual showing the wave form stops, so I am assuming the LFO is not generating or technically oscillating. Likewise when tempo sync is on and I stop the play button of the host (Loopy Pro), the wave form stops as well.
You can do this with Mela 4, and possibly the earlier Melas too, if you have them. The pic shows the host not running, but the LFO is running, and sending CC values to StreamByter. Host run/stop has no effect on this. Mela 4 is loaded as a MIDI effect, in an AUM MIDI channel. Other apps, like Drambo, may also be able to do this.

Only tested in AUM - but the LFO kept running whether the transport was running or not.. it was in free mode..
MidiMod is standalone , so no host -
though can sync via Link or midiclock if needed .
Not updated for a couple of years but worked a while ago when I last used.

mLfo is standalone or AUV3

I don’t know this one , been meaning to get …
Mosaic’s lfos are not host sync dependent
Does this do anything mLFO doesn’t do? I love his MidiGates but never got this due to already have the aforementioned app, as well as lfoh! and Rozetta.
Here's a nice feature: in midiLFOs you change the cc# for each oscillator with a slider. So you can zip through a bunch of cc#s and hear what if anything each cc is doing.
In mLFO I think you have to open a window, enter a cc, click save... tedious compared to "dialing" a value in if you want to scan the dial, so to speak.
That’s definitely a big plus for MidiLFOs and is almost enough to make me buy it now lol. Thanks!
I don't think you'll regret it. You can start and stop all the oscillators from one pane, so it's a bit less fiddly than mLFO in that regard. And couple of other features I have not really looked into yet. Finally, it's kind of a looker, as far as oscillators go...
I haven't used mlfo much but it has some great features, like being able to draw your own waveforms. It's definitely a bit clunky tho, things like drawing your own waveforms are tedious, it's very hard to grab the breakpoints. This might be a bug and I have reported it to the dev. MidiLFOs is an absolute joy to use, like all Art's apps. I think I would always prefer to use it over mlfo, given the choice, but I would definitely grab mlfo if I wanted to use some of its excellent features like the custom waveform thing, incredibly slow lfos etc. I definitely have a soft spot though for Art Kerns apps, they are some of my faves on the platform.
I love and use mLFO all the time. There’s 16 LFOs in one instance so I can set up a bunch with one instance of one app. I wouldn’t say clunky, I’d say it he custom wave drawing could be a bit smoother, but it’s not that difficult. I dialed in a really specific custom Wavetable the other day. That’s just the custom wavetables. It comes with a bunch of the usual suspects too. I don’t know, maybe it’s just a personal preference but mLFO is great. Arts app is great too, very clean and clear. I like the color scheme a lot. Both are great honestly. You really can’t go wrong with either app. Or both for that matter.
@Gavinski Thanks Gav!! I bought it (mLFO), and I have it working in Loopy Pro. I didn't know about midiLFO, I'll check it out. I kind of gave up trying to run my violin through AUM, and moved to Loopy Pro. It has a "build your own" user interface, which allows you to enable/disable multiple plugins with the press of one button; aka create a preset. Then you can super easily assign the press of that button to your MIDI foot controller.
I was gonna ask about the speed of the LFOs in the Kerns app. Do they go as fast/slow as mLFO? I’m guessing not by your comment.
I think I’m gonna pick it up. Being able to cycle through CCs like @GUB mentioned is great. I use that feature in LFOH! but it only has the one LFO so having multiple with that feature in one app would be great.
I agree that mLFO can be quite clunky for sure. I love it for experimental stuff but this one seems like a great general use LFO app
I often had problems when trying it recently with not being able to move breakpoints, so I would definitely call that clunky, though ymmv Poppa, if so you're a more patient man than me. UI elements not responding properly to touch is something I personally find very annoying. I let the dev know, he was appreciative of the info and it seems likely this is a bug, not a design choice.
But yes, mlfo is absolutely worth having, midilfos too, for anyone who uses lfos much.
@HotStrange midilfos goes down to 0.002 hz in slow mode which, realistically, I don't think anyone could need slower than! It goes up to 32 hz in fast mode. It has a beautiful manual which shows the features and is an easy read, worth a look. Or just buy it... You know you're going to anyway 😂
Another thing about LFOH -- moving between factory presets reverts the midi channel and cc# you just entered to its default values. Is there any scenario where that is useful behavior? It's far more annoying than the minor menu/panel diving you need to do when mapping mLFO. Fortunately, you can save presets for midi info in the K-Audio one, something they've denied us in their other iOS plugs.
While we're on the subject: re MLFO it's great to have the 16 oscillators, and it's nice that there's a method of quickly populating the CC values with consecutive numbers. But there doesn't seem to be a way to set the identical midi channel for all oscillators at once. Am I right about that? Also makes little sense to me, but maybe I'm missing somethin
Correction: you can set the base channel when you select the number of "outs." Never mind me, just trying to puzzle thru stuff...
I’m not sure. I haven’t really used the factory presets so I haven’t noticed that but that’s very annoying if so.
Well, take what I say with a grain of salt, I'm not sure how it's working exactly now that I look at it again...
miRack?
For sure. Also worth a look is LFOCH, though I’ve only just started to play with the latter. It does have a free running mode.
I don’t have lfoch yet. Love all the devs other apps though. That one always escaped me. And the description always seemed a bit cryptic as to what it’s actually doing.
It’s a bit odd, it has to be said - but then that’s in keeping with the experimental nature of all the dev’s apps. So far I’ve got it doing complex modulation waveforms, but it has a way of setting it up with performance controls which sounds interesting. It outputs up to 16 LFOs all of which are phased differently. So not quite an Ochd (which offers different speeds as well as phased outputs, if I’ve understood it correctly - I don’t have one).
I do love the experimental nature of his apps, I use a lot of them pretty often. Might go ahead and pick this one up just to see what it’s all about. Thanks!
