soundfont playback bug beeeeeeeep!!!!

fresh101 · Oct 20, 2003, 04:27 PM

Hi everyone,

Having a bit of a problem. When using soundfonts I noticed some of the samples gave off a continuos hi pitch tone (beeeeeeeeeeeeeeeep) after triggering them. Using Vienna I learned that it was the samples in which the local sample end had been edited that gave off the tone. I'm using the Audigy2 ex and latest drivers (this problem with 3534f also). Any help would be greatly appreciated.

Thanks in advance.

PS. These drivers are awesome , complicated , but still awesome thanks

>> in which the local sample end had been edited that gave off the tone

could you pls give more details?

Thanks for the response, here goes

In Vienna in the sample dialog box the first two parameter boxes are local sample start and local sample end. Lets say I have a snare drum with a sample length of 1000 (local sample start being 0 and sample end being 1000) and I edit the start to 125 and the end to 900 ( to remove silence, unwanted noise , ect ) I get the beeeeep tone during playback. If I return the local sample end to 1000 the beeeeep goes away.

This happens with any soundfont sample that has the local sample end parameter set to a lower value than the sample length value.

The beeeeep sound is a single high pitch tone which continues till you kill whatever soundfont playback application you have open.

>> and the end to 900

ok, I'll check 'sample end' parameter

Sounds like the famous bug.
Would you do some kind of masking or have granularity on some parameters?

Did some experimenting in Vienna and found out that the lower the sample end value the louder the beep. Also the length of the tone is relative to the release value in the volume envelope area.

not, it is not
its a simple error in SoundFont code -- perhaps, the negative values aren't interpreted correctly -- I'll check them soon

I was unable to reproduce this error - please create a (small!) soundfont that demonstrates the bug, upload it somewhere and post a link here

thanks

Here is a sf2 and wav file demonstrating the bug.

Sorry it should be fixed now.

have you had a chance to look at the problem yet? If so any ideas?

I checked the provided sample sf2 with reason 2.5 (ASIO 5.33ms) but i did not get the beep. If i change the start / end of the sample in the reason NN-XT Sampler, it's still how it should be. I use many SF2's with presets that have samples with lower end parameter and i never expierienced such an issue before.

The beep does not occur when using software samplers to playback sf2 files. It only happens when using the creative hardware to playback the the soundfonts. Try opening them with vienna (which depends on creative hardware to function) and see if they still playback properly.

yep -- sorry, haven't posted a message

it seems I've fixed the bug -- the next driver version (probably, 3536b) will include the fix

btw, concerning the reason of the bug: by default, kX driver adds special 'zero' samples at the end of each soundfont sample
if the sample isn't looped, the loop-start/loop-end positions are set to this 'zero' sample to ensure normal -note-off- event
however, if the sample start/end positions are changed by soundfont parameters, the 'zero' sample is shifted, thus, creating an invalid loop with non-zero audio data -- thus, producing a beeeep

THANKS

AWSOME!!!
