Greetings All,
Last night while a friend was recording multiple takes/lanes while looping in X2PE, we noticed that the MIDI drums (Superior Drummer) kept falling behind, falling "out of sync".

It wasn't noticeable within a few loops, but after 10 or so loops it was very apparent.

I played with the MIDI buffers, and even tried changing the clock sync, but to no avail...

What am I missing here?

Thank you for any and all suggestions.

Cheers,
MG

One thing you can try. It may or may not work, but its worth a try. Try making your loop points directly on the measure, if you didn't try that already. 

happened to me EVERY time in 8.5 pe 

but i havent checked this behaviour in x2 yet

for more loop orientated stuff i use ableton live now

I get this a LOT when looping MIDI tracks in X2. Cakewalk really needs to sort this out, because playing the notes in time seems to me to be a fundamental requirement of a DAW!

The Bakers will need a detailed recipe to reproduce the issue, and I'm betting it will turn out to be Hardware/Driver/Plugin-specific, as I have not been able to reproduce a problem with this myself. I asked for a recipe in the last thread, and it immediately went silent.

I suspect many users are not reporting this formally, using the Problem Reporter. The more people that report it with detailed steps and conditions to reproduce it, the more likely it is to get fixed, or diagnosed if it turns out to be a 3rd-party issue.


For reference, here's that other thread. OP resolved his problem by changing from WDM to ASIO drivers:

there is not much to report other than that whatever plug i use (at whatever latency) and at whatever cpu-load:

if i for example use a sessiondrummer instance with the stepsequencer and i trigger a single note then after a few cycles of loops the sound will get slowly but steadily out of sync to any tight audioloop

This happens with me a lot with drums whether it's Session Drummer, Abbey Road or Battery. I don't think that it's a driver issue because it only happens when I set a loop. If I play a song from start to finish all the way through it doesn't happen at all. But set an 8 bar loop, for example, and it starts drifting relatively quickly. It's a real pain if you're looping a section to audition sounds, because you have to keep stopping and starting to "reset" the timing.

agreed - especially since on the same sytsem i can run ableton live loping itself into exstasy without any kind of problem :-)

Something's different in your environment.

I can set up an SD3 track (Simple Instrument or separate MIDI and multiple audio output tracks), bounce the audio to another track, invert the phase, loop any range , and the live SD playback will null near perfectly with the audio track for as long as I let it run.

I say "near perfectly" because SD3's real-time MIDI playback is never a 100% consistent to the sample, so you'll hear a a little smidgen of a hit sneak through every once in while, and the tracks can get out of sync by a few samples if you restart playback in the middle of the loop or the loop isn't right on measure/beat boundaries (i.e. not a whole number of audio buffers), but there's no cumulative sync error over time; they'll just drift in and out of phase - first one way and then the other - as the loop iterates. Of course, this isn't ideal behavior, but you're only likely to hear it when trying to null two identical tracks like this. 


I don't have Abbey Road or Battery, but the same pretty much goes for any other synth I try this with - drums or otherwise.

If you can post an example project somewhere using only SONAR-bundled instruments, I'd be interested to see what it does on my machine.

I also noticed this the other day! I use ezDrummer and after the third loop, the drums were falling behind. After seven or eight loops it was completely out of sync. I never had this happen in X1. I haven't created a problem report.. yet.
