Sample length in Dimension Pro
This is my first post, and sorry if it's really basic...
I've been using Dimension Pro and Sonar 8 to record backing tracks for a little while, but I have mainly just been using a piano sound. However, I've recently started doing some other instrumental lines, and noticed that after a certain amount of time (4-5 seconds), the sound just stops playing, even though I'm still holding down the note.
Is there an easy way to make certain patches sustain longer? I'm talking about patches like vocal ooh, sax, trumpet etc. I realise that lead sounds and organ sounds will sustain indefinitely, however I'd like to make other sounds last longer without having to resound the note.
What's the best way to go about this? I've had a fiddle with changing the amplitude envelope, but this doesn't seem to have any impact on the length of the sample (if that's even what it is...).
Any help would be greatly appreciated!
Thanks,
Adrian

The first and easiest thing is to make sure the sample in the amplitude box has a sustain point. You can add it to the amplitude control by clicking on the envelope line to add a point and typing S. It will place a red line at that point.
The SFZ controls the legnth of the sample, too. If the sustain trick doesn't work, you'll need to look in the SFZ files. That uses a basic text control for mapping and other properties.

Awesome, thanks. I already had a sustain point, but I'll have a look at the sfz files.
I'll let you know how I go...

Hmmm... I looked at the .sfz files, and had a look at the .wav files they were pointing to. The problem seems to be that the .wav samples are only about 6 seconds long. How do organ and lead sounds use the same ~3sec sample over and over? It'd be great if I could apply that to other samples. I tried loading a lead sound, and then pointing to a sax .sfz file, but the sample still cut out after about 6 seconds...

You might want to post the sfz file. I'm not good at it, but René (who invented SFZ) and others here are familiar w/ it and could probably point out the problem. If you've enabled a sustain then there is something in the sfz file saying play 6 seconds and ignore the sustain - that would be my guess. SFZ is the 1st order controlling aspect of a sample and it is probably some breath emulation.
You could use a different SFZ file/program - organ, say, and drag your sample into DimPro then.

The .wav samples themselves need to have loop points defined, too. One shot .wav files don't have loop points so won't sustain indefinitely. But samples that have loop points embedded in the .wav file can be sustained indefinitely.
You would need a .wav editor like Audition, Audacity, Goldwave, or Sound Forge to modify a sample to create a loop point. Then you can use the GUI controls or the SFZ directives to tell the instrument how to handle the sustain for the modified samples.

Thanks so much for the help. I've uploaded the .sfz file I want to use (as a text file). I'm happy using Audacity, but I've never used it to define a loop point. Is this relatively easy? I had a quick look in the manual, but couldn't find loop point. This seems like a rather convoluted way to solve this problem - I actually thought when I first asked this that it would be easy to fix... Thanks, Adrian

I've used audacity in the past...I thought it had that capability, but maybe it doesn't. I use Sony Sound Forge now, and I know it has the capability.
