Sluggish and slow...

I've noticed on the current show I'm working on SCS has started to become sluggish and slow. Sometimes in playing back cues, cause clicking and delayed cueing, but mostly when pressing 'stop all' the the cue list will 'hang' for a few seconds then flip up the editor window . It's intermittent and random and I don't feel I'm doing anything I haven't tried to do with the program before so I don't think I'm 'pushing' it too hard. I've tried the show on 3 different PC's too.

I've noticed that all the files my composer has sent me are all 32bit and the rest of my sound effects files are all 16 bit. They seem to play on their own fine in the program but when I run them in sequences together is when I tend to get problems. Is this a known issue? I will as a mater of precaution change all the composers files to 16 bit but just wondered.

Pete.

Whilst not being able to comment specifically on your problem as a known issue, things you can try to improve performance include adjusting pre-buffer length and playback buffer length, also reducing the number of audio files to pre-open.

We've sorted this out. The performance issue was caused by having 8 default devices set in the Production Properties and having all 8 devices assigned in every audio file cue, even though most cues needed only one device. Every device assigned in an audio file cue causes SCS to play the file to that device, even if the level is set to minimum (-96dB).

Remember that in the Production Properties, the default devices are just that - defaults. They specify the devices to be automatically included in new audio file cues. (Changing these defaults does not affect existing cues.) In an audio file cue you can remove auto-selected devices and/or add other devices. So for each audio file cue you should include only the devices required by that cue.

NB in all of the above, 'cue' always means 'cue or sub-cue'.
