I tried to crash doing this over and over but can't. Sounds like a nasty bug.

Just want to confirm this nasty bug!
Happens here too more often than not.
Most relevant specs: WinXP Pro / Terratec EWX 24/96

well, it's almost normal to have crashes when changing buffers with audio playing. It's like changing a tire when driving you know, there are poor chances you won't go straight in a wall...

True... True...

But there is one time I do this and that is when you record and you need low latency and
then you switch back to more latency to free up some CPU when mixing.

Spoken for me, I would not even dare to change the buffer-size while the sequencer is running. It crashes here, when it's NOT running. But maybe some audio engine is running in the background and that leads to the crashes.
All other application I tried (including eXT1), do not crash, if I change ASIO buffer size.

Dudes, could we please keep this thread on topic ; i'm really concerned about the graphics issues.
Maybe soma could add the latency crash to its known issues post...?

It does this whith no audio playing though.

bah !

One hour and an half playing with XT2. 3 hangs, one editing Polyblit, other trying to make and envelope for Polyblit, and the other editing ImpOscar.

I also have find some misterious thing, when returning form a crash that make Polyblit untuned.

By other hand, I've fighting against Rez 1.3 beacause program doesn't save the resonance state of my preset.

And returning to the latency issue, I'm upset of changing latency and even drivers in a common famous application without problems. Since I left windows 95 I haven't had so many hangs as today playing with eXT2. To be honest, althounght I have purchased the "support", I thing the program will be not ready and middles of June. For me, is impossible to trust in this application, at least today.

The glitching when doing anything, for example dragging the mouse to select notes, has been here since the beginning. It makes Ext2 completely unusable for me.

CPU utilization is only at 20% or so in playback, and happens even with an ASIO buffer of 1000 - though it should be smooth at 256 at least!

Pentium 4 2.8C
1 GB RAM
Win XP
Geforce 6600GT AGP video
M-Audio Audiophile 2496 or ESI Juli@ soundcard with their ASIO drivers (I upgraded to the Juli@ - no improvement).

Any Linux user has something to report about this ? What's the cpu like when moving comps in main ?
It 'd be interesting if anyone with a faulty XP setup had the possibility to check under linux if it's the same or not ....

Oh, and I want to add that other sequencers work just fine here.

I hate to say it, but I have a nasty feeling that it's just inefficient programming that somehow majority of people shut up about. I.e. priorities have been in adding features in expense of making the core functionality work well.

I had this happen to me recently. everything seem to run fune, until i decided to load Shortcircuit with an 80mb drum library, and now i get glitches when miving things around, etc. minimizing XT2 so it doesn't show in explorer seems to help.
i've had graphic glitches since XT1, and i've mentioned them several times. could it be that xt is trying to access RAM from the system for graphics, instead on of the video card? (wild guess, lol)
My specs:
P4 2.4, Win XP SP2, 1gb RAM, Radeon 9000 128mb, and I run all my XT projects from an external HD.

Does the Radeon grfx card have it's own memory or does it share memory with the motherboard?
Just wondering I have no idea if that is related to the issue.
edit: never mind it has 128 mb.

Do you have this problem when you run from a fast internal drive. I wonder if the external drive is clogging your FSB and slowing down your graphics. do you have PCI or PCI Express?

sweet_trip · Post by **sweet_trip** » Tue Jun 05, 2007 8:58 pm

i dont think it's the ext.HD. I use it with Cubase SX2 and it works fine. In fact SX2 is the only DAW I own that gives me glitch-free performance. When i switch to Ableton Live or EnergyXT, things are not as optimal.
Yes, it's a 128mb video card, PCI.
I forgot to mention I'm using an Echo Layla24 laptop audio interface. And also, yes it is a laptop, but does not run on a laptop processor; it's one of those heavy-ass "portable-desktop" laptops running a desktop P4.

Let me put it this way... I can play Doom 3 on my laptop for hours.

soma · Post by **soma** » Tue Jun 05, 2007 9:11 pm

Yeah but DOOM 3 isn't HD heavy like music is. I could be totally off here but I think that Xt might not be optimizing caching very well and you are getting big paging of memory on your HD. Combo that with having to access the FSB that is also potentially competing with an Echo and it could cause problems for either your sound or your graphics. It would have to be programmed very well to work perfect (SX might be doing this).
Try to save everything for a big project temporarily to your HD (including 80MB sounds that go to RAM) and see if your problem is just a s bad. (just for troubleshooting sake)

Are you using ASIO for all or the Echo drivers?
