No. Sound doesn't "cut out". The sound works fine on the first channel. ONLY when you add it to an app in the second channel, then go to adjust frekens, the second instance of frekvens moves the sliders, but no change or effect to the second channel app at all. I tried several and it does this consistently. You can see that the values of frequency, gain, etc. just read "0" even though you're moving the adjustment sliders.
I also tried deleting frekvens, restarting, and trying again. Same thing.
It works fine if I only use one instance of it. Only when I try to use it on a second channel does it fail. Which, kind of defeats the purpose of having an AU app.
@skiphunt Sorry, my brain isn't working, too tired I think. I meant what you said, I couldn't recreate that behaviour. I am running two instances fine over here, I might sleep on it, see if that helps me figure it out.
Cheers

What is your setup for 2 instances? I'll try on my end and see if it's related to just the apps I'm using or my particular device (ipad air 2, latest IOS)
@skiphunt I use the same, iPad Air 2 with latest iOS 9.3.2 and followed your guide.
channel 1: Load launchpad into a channel -> add frekvens -> start some loops -> go back and adjust some frekvens parameters.
channel 2: Load Sector -> add frekvens -> start a loop in sector -> go back and adjust some frekvens parameters.
That you see 0 is interesting, I think that could be an important key in this puzzle. I just need to get my brain working.
Cheers
Erik
Hmmmm... that is exactly the same. Only you're not getting the "0" reading with no effects of frekvens on channel 2. That suggests that it's something to do with the installs of one of my apps, or my device? Could it be the particular Launchpad pack I'm using?
I'll try some other combinations later and see if it's completely consistent between a variety of apps. I've already done a hard restart too.
@skiphunt It's a tricky one. It shouldn't be the Launchpad pack I don't think. From past experience it is most likely caused by me doing something stupid, that happens probably 99 times out of 100.
Sorry about this, I will do more bug hunting tomorrow.
Cheers
ERik
No need to apologize. You're bravely navigating unchartered AU waters. I commend you and thanks for working to take your apps to the next level.
It's been updated again (24th). Issues fixed?
@pichi Version 1.3.1 released on the 24th fixed a ui quirk that happened sometimes when the host went from background to foreground. The issue where the au parameters aren't updating in the second instance is still a mystery.
Cheers
ERik
FYI: tried several different scenarios. Always the same. Second instance of Frekvens loads in slot, but sliders don't effect source. Frequency slider reads either "0" or "-0" when sliding with no audible change. Gain reading stays at 100%, and same for other sliders.
I also tried creating second channel with new source and Frekvens as IAA. First channel with Frekens as AU works fine. Second channel with Frekvens as IAA also works fine. Added 3rd channel with Frekvens as AU, no response or effect to source.
@skiphunt Good testing. Just out of interest, what happens to the third instance if you create three audio units?
ERik
The same. Tried 4 too with same results. Tried adding 3 AU channels, then a 4th IAA instance. First Frekvens AU continues to work, and IAA works. Any more than 1 instance of Frekvens AU instances does not work. Also tried solo'ing each channel. Same thing, no effect.
@skiphunt Interesting, in a broken instance, is the wave visualizer thing still showing the incoming sound?
Thanks
ERik
Yes. And there does seem to be a slight effect of the instance, even on broken instances... but no feedback from sliders. For example. If Frekvens AU is added in a second/third broken instance, and I slide it over (disengage) in the AUM channel, I can hear a change... more of a slight level change though. The level drops slightly with the 2 or 3rd broken instance engaged, as opposed to not-engaged. But none of the slider for any of the parameters effect the sound and the slider readings seem stuck on whatever the default setting is. Does that make sense?
Excellent, this is good, the plot thickens.. Would you mind if I add you to the beta on testflight? Just send me your email in a private message if you are up for it.
Cheers for testing.
ERik
Sure
Is it possible that the problem only occurs when using Frekvens as both an AU and IAA Effect at the same time? Not sure why you'd do that but...
I tried to replicate the problem here, with multiple AUs and then adding an IAA instance, but couldnt get it to fail.
Trying it as both instances was just a test to give the dev more behavioral data to work with.
It's great you're not able to replicate, but I havent noticed any other irregularities other than this repeatable failure even after multiple hard restarts. I've also tried multiple apps and have deleted/reinstalled. One thing I haven't tried is deleting/reinstalling AUM. But the other AU apps I have don't do this and seem to work fine.
Actually, the only other AU that I have and will load into the FX slot, is VoiceRack:FX. It functions fine in multiple instances and channels.
@humbletune Just tried deleting AUM, hard reset, reinstall of AUM. Still the same problem.
Then, I realized that all of these apps I'm using are happily universal.
So, I tried the exact same original set-up on my iPhone 5 (latest iOS), ie. AUM, Launchpad w/frekvens AU in chan 1 and Blocs Wave w/frekvens AU in chan 2. Same exact behavior as my iPad Air 2 running latest iOS.
So, this isn't specific device related. I can repeat the same error with frekvens between 2 separate device installs.
@wim @skiphunt I think I have a fairly good guess of what is happening. I think it is to do with multiple threads invoking the start of a new instance, which can explain different results on different devices and occasions.
I will submit a beta now, it usually takes apple a few days to review it, before we can test.
Thanks for the help.
I would never have found it alone.

Frekvens update v1.3.3...
Erik, thank you.
These several updates have Frekvens on adulthood.
I have very few touches on Frekvens AU extension before this update.
Just having smooth operation on it today, a theoretical understanding how it sounds like just few tweaks.
This app is creatively awesome by design.
Have you done fixing issue with several channels instances plug and play? Our Sir. SkipHunt is questioning?
Hilbert transform has been put in good uses on stock and futures market technical indicators charting.
It is an efficient algorithm to design cycling indicators' preprocessing for short term trading purposes and save CPU power at meantime.
Anyone else had any issues mapping freq to a CC? Only tried in AU
no, it doesn't seem to receive MIDI. Also tried as AU, but that shouldn't make a difference. I point directly to Frekvens from Lemur, no parameter change.
@Kaikoo2 Hi, yes the issue @skiphunt experienced was fixed in version 1.3.2.
@OscarSouth @Phil999 First please make sure that midi cc is enabled and you are listening to the correct midi channel number. If that doesn't work I would love to hear more about your setup so I can recreate the problem. The AUv3 version of frekvens does not support midi per se, but it exposes its parameters to the host app. Depending on what the host app is capable of, midi could in theory be connected to these, for instance AUM allows that.
Cheers
ERik
@Phil999 Hi, just bought Lemur (I am guessing your using the app, because there is lemur hardware also if I remember correct) and tested it, works fine for me. I am not sure what the best approach is here to solving this other than to recheck your settings. I am not very familiar with lemur, just spent 2 minutes with it.
Thanks
ERik
Everything works flawlessly for me apart from frequency parameter doesn't respond linearly to my midi cc input (0-127)
Jamming with frekvens controlled via midi hardware sounded unbelievable by the way. Even without dynamic freq control!
how did you do it? This time I sent MIDI first to AUM, and routed inside AUM to Frekvens. Still no reaction. But I'm not too familiar with AUM. I simply used its routing matrix.
Thank you Erik for the reply. But ... how did you check MIDI connection from Lemur to Frekvens? Frekvens has no background audio, as soon as you switch to Lemur, there's no audio passing through.
From external MIDI source (outside the iPad) I can control Frekvens without problem.
