Hi Thanks for the replies Anticipative FX is already disabled. UAD-1 synchronous mode is enabled. There's no stuttering at all apart from on playback start when the cursor is over the clip being played and that clip has UAD FX on it. I therefore don't think it's an IRQ issue...
Hmm, it gets worse. If I try to glue a clip that has UAD fx on it, then I either get a file which is completely silent apart from some sparse glitching, or the glue works, but the first 10 sec or so of the output file is totally silent. If I render a clip using fulltime offline, the results are fine. If I use 1x offline, then the first 2 secs of the output file are silent (the silent part corresponds to where I'm hearing all the glitches when playback begins.) Basically in order for playback to begin correctly, I have to start playing from 2 seconds before where I actually want to hear. Which is starting to suck! btw I have since moved my soundcard to its own IRQ - it has made no difference.

Well, I recently upgraded to a new i7 system and reaper 3.11, and can report that glueing of items with UAD effects is still broken as per my earlier post :(
FunkyDrummer with respect it should be undrstood that other cards shareing the same bus with the sound device, eg the pci bus..can cause problems for the sound device. ive seen this occur many many times. this is why i dont use add in dsp cards. in summary my rule is whatever bus the sound device is on, i dont install any other device useing the same bus. think of it like this. think of a bus like a freeway for cars. at 3am , all is fine cos just a few cars. but at rush hour (lots of devices)..traffic jams occur. in your case with pci based dsp cards you might want to run a test with a different sound device on say the fw or usb bus, and see if the problem goes away. if it doesnt , next thing to check are drives themselves. if your useing the same drive to record to as win os is on, test recording to a dedicated seperate drive. i dont know if there are utilities available to monitor the pci bus, but if you can find one that operates in real time.. , with all your dsp cards installed it might be usefull to monitor the traffic pci load. and see actually what is going on. i'm sorry but i havent kept up with any available utilities. am i correct in thinking you have different clips at many different times with dsp fx on them ?? mebe the in/out //on/off nature of the process in itself is causeing problems. how many clips are we talking bout here ??
Thanks for the reply Since I upgraded to a faster system (to core i7 from P4) the glitches I described in the first post are no longer a problem.... But the problems when glueing still remains. Here's what I do: create a new project add an audio clip (say a drum loop) on the drum loop, add one or more UAD plugins glue the item the resulting file is mostly silence apart from a couple of glitches Can someone else with a UAD card reproduce this?

FunkyDrummer as far as i understand to print hard the fx to a clip one uses apply fx. (right clik over clip). when finished so you dont get double fx, remove plug in. if i had say 3 seperate clips on one track , i would hard print each one individually. then..after fx removal drag/hilite all 3 , right clik n glue as the last action. mebe others know another way.
