Problems with rendering mix

[GYang]

After finishing complex arrangement with several VSTi + samplers etc. I faced some crazy rendering problem.
When I listen to mixed tracks in Tracktion (not rendererd wav files) everything is OK. After mix is exported to wav. file and opened anywhere, I found that one of VSti (Novation V-Station) is much louder (distorted) on some part of the song without any reason. When I reduce number of tracks (from 14 to this problem with same VSTi and same track disappears.
So, rendering problem arises in connection with larger track number.
Did anybody have such problem and what can be way out?

Thanks.

I've not had that particular problem, no. Some plugs don't like being rendered faster than realtime, so it might be worth trying your export with "render at 1x play speed" checked.

failing that, try rendering just the problem track into the project directory: if that works try the export again with the rendered track instead of the VSTi..

also ... what are the 6 tracks you removed holding ???

Removed (practically just muted) tracks are all MIDI tracks for other VTSis, but it is not depending on which particular track is removed, just the fact that less tracks are in use. In same time CPU usage was never under question or near to critical.

Rendering track alone goes without problem, but although I can work this way, I wonder is it a kind of Tracktion limitation or bug.

Next problem I found on same mix is related to GIGA Studio that is my most important source. As I use it as VSTi via FX-MAX GIGA VST adapter the story is same. While editing and mixing is no problem, but rendering 'changes' some parameters (via MIDI) in GIGA and I get somehow changed track )although not with such distortion that occured in V-Station.

I must say that both V-Station and GS are amongst my most favored instruments, so such flaws are big disappointment.

Another thing to try is to render at the same bith depth and sample rate as your project settings. Some VSTI (Wusikstation comes to mind)don't do well when rendering at different sample rate than the project settings in Tracktion.

Is there any other practical way out, for example not to render mix, but just to output mixed stereo signal to some other program that would record it as two channel track.
This would be preferable, as I could do some manual changes (minor of course), during such mixdown.

Thanks for suggestions.

with decent soundcards you can often designate the 'master mix' as an extra input in tracktion which you can then record.. i used this approach to work around the audioclip rendering bug with my audiophile24/96 and now i do the same with the emu 1820m.

Well, I'll try.
