Pop & Crack in Midi only project
What can cause a midi only project to crack and pop on playback?
Ten track mix of True Pianos, Rapture, Dim Pro and Roland Groove synth
X1b prod- 246 midi playback 512 ms buf (not dropping notes...)
Audio - 44.1 @
16b Asio - 512 buf size
reported latencies = I - 15.9 msec. 699 samp. O - 31.7 msec. 1398 samp
XP sp3, Dual Dualcore Xeon xtrm, 4g ram, 2.5 tb hd, line6 ux2
any help appreciated...

Hey ggg
Are you using a control surface?

There's no such thing as midi only if you are using soft synths. The audio has to come from somewhere!
You can try freezing a couple of tracks to free up some CPU - or, during playback raise your latency level some. Low latency during playback can be a waste . . .

Yes, I use a Novation Remote 61 SL
@Stone
Sorry for the poor description. Yes, audio is coming from softsynths through instrument tracks. My point was that there is no recorded audio. CPU seems to hover around 25% during playback but one core is higher than the other seven but isn't peaking. I will try a higher latency number but my question would be asio or midi?

Yes, freezing will be good when I'm done tweaking but now things are in flux.
My question - Is this typical? 6 - 10 soft synth instances and things crack up? Or is it my audio chain? 1398 samp on playback not enough?
Or, is there something fundamental that I've not considered?
Thanks again,
ggg

ggg - It takes much more CPU power to drive a bunch of synths in real time than it does to play recorded audio - I think you get that now from the other answers. If you've upped your buffers and still have a problem, then bouncing/freezing will free your system up. My computer is way under-powered by today's standards, so in my projects with 30 or more synth tracks, I'm bouncing to audio several times before I've constructed the whole project.

Also, freezing is just a temporary bounce for those tracks that you are not tweaking at the time. Unfreezing is a snap.
Just remember that tweaks to frozen audio go bye-bye if you unfreeze!

Thanks all!
I guess I'm just disappointed that a machine that shows 8 cpu's starts to puke after 6 softsynths @ 30%+-. I was kinda hopin' I was jus' being slow.

"8 cpus"--? Do you mean 8 gigs of RAM? Just not clear what you mean. RB

As said earlier - many things beside CPU's can cause a little glitchiness - including whether or not your audio device and its drivers are up to the task. Brian

Well, I guess there are really only 4 cpu's but they hyperthread so it shows up as 8. 4 gigs of ram.

Yeah, might be my audio device. Still just disappointing... But, if it's the audio device shouldn't it crap out with a similar audio at some point?

I think that you are trying to isolate the cause - but what I meant was that when you are playing back and creating audio in good amounts at the same time (rendering from synths) there are many pieces working together that contribute including processors and audio drivers. Did I mention video as well? : ) Brian

How many softsynth tracks will run concurrently (non-frozen) before your setup cracks up? Seems to me we ran a forum test like that with a standard midi file to loop and add tracks and synths... Looked for it but didn't find it. Might be interesting to run a group test like that.
You would have to define the test with exact synths, midi events and patches to add in a certain sequence to get like kind results...
Oh, well... I guess I'll just go back freeze some tracks and try to make music.
