Latency with DXi soft synths on Sonar X3 [Solved]

Hi

I'm sorry to insist on with this issue, but I've seen on Wikipedia that DXi soft synths were created in partnership between Cakewalk and Microsoft ( https://en.wikipedia.org/wiki/DirectX_plugin#Types_and_compatibility ).
Maybe this could be related do DirectX version on Windows 10? (Despite I've checked DirectX effects and they seem to be OK).
 
I also installed Sonar Artist demo version, but the issue continues. 
 
Thanks.

Hi, Doktor
 
Yes, my Sonar is X3e. I reset the VST plugins and re-scanned them, as you suggested, but still didn't work. Thanks for your response.
 
I’m using some VST plugins like Sound Center and SI, until I can get DXi synths working.
 
Thanks!

DX plugins do not need to be scanned. 

Actually I've seen a few threads where a VST reset resolved the issue, sorry it didn't work this time.

Well that is what you would assume. Nevertheless the threads are out there if you google. Suggest we move on with the thread...

2 and 7 seconds is horrendously long for latency. Its measured in ms (milliseconds) not seconds. You may have misspoken. If not than you have a real problem.     

OK - I just looked up your listed audio interface - the Behringer UCA 202, and it lists no drivers of its own whatsoever.  It's driver downloads search page returns only a link to get ASIO4ALL, which is VERY often problematic for folks.
 
ASIO4ALL is a wrapper bit of software that fools programs into thinking they are using ASIO, but really they are using WDM Windows drivers.
 
While ASIO4ALL does work for some, for many others it is just a problematic piece of crappy software that causes issues just being present on a computer, let alone using it.
 
I do not know if you have the latest version of ASIO4ALL, OR what the stability/usability of it is on Windows 8.1, so that is something to check out.

Hi, thanks for the responses
 
At first I was using ASIO4ALL from UCA202 page on Behringer site, but for some reason I found the Behringer USB Audio Driver 2.8.40, and I remember it was better, as I was using an old notebook, with 1.7 GHz CPU and 1 GB RAM, running MC5.
But yesterday I was browsing the web and I couldn’t find it on Behringer site, but just on third party sites offering drivers downloads, so I quit searching. It makes sense now when I read azslow3's post.
 
I also tried to bypass all plugins with the 'E' key, but didn't work.
But what it’s weird is that this delay just happens if there are tempo changes on the project, as if I delete them the issue is gone. 
 
Also it happens that my midi controller is a legacy product, and I’ve seen people on internet which couldn’t use it under Windows 8. Fortunately I’m using Windows 10 and the keyboard is working, but I wonder if there is any relation.

Hi azslow3
 
Yes, that's the bug! I was thinking it was a particular issue, but at least now it could be detected. Maybe there's something else. I'll try to search google about the discussion, or maybe it’s solution. : )
 
Thanks

2 unanswered threads with may be related problems (when created my test project I also got no sound from TTS-1 till some "manipulations"):

So glad to have found this thread, this has been driving me crazy all night.  Windows 8.1, SONAR X3 Studio.  After messing with this in a complex project, I tried a test project to make sure it was the same issue described:  blank project, added TTS-1 synth (separate audio & MIDI tracks), grand piano patch.  Played my controller, no latency at all.  Added a tempo change at measure 2.  Playback still fine.  Moved now time to measure 2 and latency jumped to +5 seconds (not milliseconds, seconds).  On the meters I can see the MIDI hitting in realtime as I play, but the audio meter doesn't react until several seconds later when the sound plays.  Selecting a new now time didn't fix the issue.  Close/reload project fixes until you get near another tempo change.  Enabling loop (without playing) also has the same effect if there's a tempo change within the loop period.
 
Other synths I use regularly (Dimension Pro, SI-Electric Piano, VB3) do not have the issue - but they're all VSTs.  For second test I tried using Rapture (another DXi synth) and it exhibits the same behavior.

For second test I tried using Rapture (another DXi synth) and it exhibits the same behavior.

I would recommend using version 1.2.2 of Rapture. The DXi version was dropped around 5 years ago. If you do not have a recent installer the update is here http://www.cakewalk.com/S...apture-LE-1-2-2-Update

Hi, cbarnabo
 
I'd like to say that other DXi soft synths have the same problem on Sonar 64 bits (please note I didn't try Sonar 32 bits on my system, but on Music Creator 6 the synths work fine).
Also CW support team asked me to try freezing the midi clips on MC 6 and open the project on Sonar, and I saw it works, as the issue occurs only on real time access to the midi controller, when the project is not running or being recorded.
 
I also browsed the web sometimes to find a multitimbral GM2 synth, but didn't find one yet. I tried a soundfont file I found on internet, but I didn't like it too much.
 
Best regards

Cbarnabo, thanks for the suggestion. I'll try to see it.
 
Best regards

Thanks Bob ... I've been using Cakewalk software for literally decades (and was thrilled last year when my ancient 20th-century edition of Home Studio still qualified me for upgrade pricing to SONAR), but I'm finally stretching to where the forums are a HUGE help.  I've had SONAR over a year, but my focus has been almost exclusively using it for live performance (not why I bought it, but it's handling the job really nicely).  Now I'm getting back to arranging and composing (which is what I used to do and why I had originally bought SONAR), and getting a lot of requests to help record & master material (totally new territory for me), so I'm learning on the fly getting up to speed "everything else".
 
Man, do I wish I'd had this when I was doing community theater sound 20 years ago.  :-)
