Topic: Weird fader behavior when quitting DAW

Hi.
First of all I have to say that I love my AlphaTrack. It works great with DP 6.02 and it makes everything easier.
I'm just getting a weird behavior when I quit DP. (and it happens randomly ) My settings are Mac OS 10.5.5, DP 6.02 , AlphaTrack 1.3 driver, intel Mac Pro 2,8 Ghz 8-Core.
So, sometimes when I quit DP, Alphatrack's fader gets stuck in the middle of the fader's line ( let's say 0db ) and it keeps making this click noise , as if it wanted to get unstuck . (sorry about my english). If I unplug it's USB cable it stops , but if I plugged in again it starts clicking . The only thing that fixes this AFAIK is to unstuck it manually (but I'm afraid that someday I will break it).
I've notice that the normal behavior is that when I quit the fader should go all the way down, but somehow , sometimes it gets stuck.
Do I have a deficient unit? Is this normal behavior? what can I do ?
Thanks in advance for your help.

Hello Yayomorales,

I have been playing with this one a little bit over the last few days and haven't been able to reproduce it yet. I suspect that the AlphaTrack is getting caught in some weird state just as DP quits but I'm not certain what it is yet. I doubt that there is an actual problem with your AlphaTrack itself.  I will keep trying to make it happen here but in the mean time, if you notice any clues or settings that might help me create it, please do let me know. Particularly your Automation Setup settings for the selected track when you quit DP.

Thanks

Also, try running the calibration routing on your AlphaTrack and let us know if it affects the symptom at all.

Shift+Stop+F4 and release.

Thanks,

Hi. I must say I'm very impressed with your tech support, I wasn't expecting an answer so quick.
I did the calibration stuff now and so far it looks that everything is working fine now, But as I said at the beginning that behavior was random , so if it happens again I'll take note of every little detail (autom, pan, VI or Plugin, etc)
Thanks a lot for your help.
Best regards.
Yayo.

Re: Weird fader behavior when quitting DAW

Hi.
Here I am again to report that the weird behavior is back :(
But now I get more info than before just in case this odd behavior is happening not because AlphaTrack but 3rd part plugins or applications.
This happened again when I was trying to use DP6.02 in the background while trying to use my MIO (MetricHalo) console in the front. So I decided to move to a different track using AT's right/left arrows (with MIO console in front) and when I arrived to a certain track it just happened again, the fader got stocked and making that click noise.
That track had an insert of Waves Maserati Drums plugin and it had this characteristics:
Auto was set to Latch. and it was on [read](but it didn't have any autom. yet)
Track was also set in SOLO mode.
That's all I can say, I had to force the fader to make it work normally and get released.
I'm a little concerned that my AT might be broken...(as it isn't working as is supposed to)
Any help will be appreciated.
Thanks in advance.
Yayo.

Re: Weird fader behavior when quitting DAW

Ok, let me try to repro this. I only have the stock DP plug-ins but we'll give it a try. If it only does this when the AT is focused on that particular track then I wouldn't suspect the AT is broken. But if there is something about the track configuration that is cause this behavior maybe we can  find a way to avoid it.

Keep up the good work with the details.

Hi again. Thank you very much for your support.
Well it happened again and this time MIO console wasn't even opened. So I guess it isn't MIO console's fault. On top of that, this time it didn't happened on an audio track. It was a midi track (as I was using only VI).
This midi track had auto [on] in latch mode and also auto(rec) [on]. No plugin inserted...just midi tracks running.
I really don't know what the problem might be. Just need your advice, as my AlphaTrack is brand new and I have a guaranty , so maybe I could exchange it for another one. But for that I will have to have your recomendation , so I could call (Thomann) and tell them that you guys told me to ask for an exchange.
Anyway, whatever you tell me to do best, I'll do.
Thanks again for your help and sorry if I'm being such a pain
Yayo.

Re: Weird fader behavior when quitting DAW

No pain Yayo. Happy to help.

Well, I have still not been able to reproduce the symptom. And the fact that it has occurred for you even when DP was in the foreground (MIO not running) makes me begin to think maybe you have a defective unit. I wish I could be more sure of that.

I guess you should consider swapping it out with Thomann while it is still new. Let me know how it works out.

Re: Weird fader behavior when quitting DAW

Hi again :)
I just got in contact with Thomann crew and they told me to send my AT back so they could check it and exchange/repair it.
As I was having this issue randomly I've decided to wait to see if it happens again. I've being working for a whole week and nothing, but suddenly... click... fader stuck again :(
This time with a totally different configuration and MIO wasn't even opened , so I'm convinced now that my AT is broken and I will send it back to see if they can repair it or exchange it. Just in case I took a little movie with my mobile phone when last AT event happened and here is the link just in case you want to check it out.
I'm sending this movie to Thomann too just in case they can't reproduce my problem for them to see that it is actually happening to me :)
Thanks for your help.
PS. Any comment about the movie and AT behavior will be appreciated

Re: Weird fader behavior when quitting DAW

Hello Yayo,

That sure doesn't sound as it should. I think you are probably right to swap it out. Let us know if you see the problem again but we hope not.  Just be sure that the AT is getting good power and that the computer power is properly grounded to prevent AC noise from bleeding back into the AT.

Best,
