Note Cut-off during playback

polo9n

Hi, I have a problem while playng a midi file with a midi player (Vanbasco, Winlive, etc..): the file play perfectly but when I mute a track (1-16), for a second there is a total cut-off of sound. With the original creative driver and the same soundfonts bank the problem there isn't.
Why???

Thanks to all and sorry for my bad english.

try checking the 'LEGACY RELEASE/DECAY' in the KX 'Synth compatability...' settings.
Right click on KX tray icon - settings to access this.

Hi, thanks for reply. I try to check LEGACY RELEASE/DECAY but the problem there is again. Do you have any other idea?

Thanks

well, there is also the possibility of normal polyphony 'note' stealing - that will happen more often if the soundfonts used contained 'layered' voices - IE if 1 note is shtruck, 2 or more oscilators are being used (there are a limited number, 64 IIRC) watch the KX Mixer Analyser while your midi file is playing - if you see ALL the 'meters' up at the same time - its note stealing that its indicating - this is normal and nothing you can do about it.
edit:
Nothing you can do short of using SF's that DONT use 'layered' voices/patches.

Thanks Maddogg, I use Fluid R3 soundfont but I try many other soundfonts and the problem It's the same.
Why with original creative driver I don't have problem???
I'm whatched the Analyser but I don't see ALL the meters up at the same time.
When I mute a track all meters break down for 1/2 second.

You can suggest me another test/solution?

Thanks for all

Well - you could try KX version 3538H (if you try 3538I - theres a MIDI CH 10 Drum issue - that although can be 'worked around' with an add on made by a user (Russ) here -
http://www.hardwareheaven.com/general-discussion/96405-midi-drums-do-work-3538i.html

I tested this only for a little bit... so I cant say how well it would work for you..

But I used 3538H for sometime - but I may not use all the polyphony that you are attempting.

I DID hear some 'early' note stealing with 3538J - but was improved with the Legacy RELEASE/DECAY setting.. ??

Also - Fluid DOES use alot of polypohony - and theres 1 BIG difference I see in KX than what I have read about CL's method of 'polyphony management' ...

In CL drivers - Ch10 would have priority (in other words - it would be the LAST channel to 'steal notes' from when another note is trgiggered and no polyphony is available.
So the priority list was as follows:
10, 1,2,3,4,5,6,7,8,9,11,12,13,14,15

This way - the drums (like cymbles, or other longer released notes) would not get 'chopped' off before completeing their release cycle un-neccessarily.

In KX driver - it seems to simply - be 'First in First out'... its not the preferred method, because - it *can* cause the more easily noticed drums to 'choke' off to soon, when possibly a less noticable instrument (like a piano note in a played chord) could have been taken instead.

Did this make sense.??

I beleive this is why you hear a difference betwen CL and KX.

IE - it was happening in CL - just less noticable.

Also -as a test
In the midi sequence your listening to, try lengthening the notes for the instrument you notice cutting off - avoid overlapping notes tho)

I BET it will improve.
I'd also wager that; THAT instrument (the most noticable one) your hearing cut off is using CC64 (sustain).

edit:
Also - as another test,
try muting a single track - and see if it improves.
If it does THAT trak either:
1) is using chords
2) an instrument with layered voices

or both.
