Hello starrmark!
There are some points in your description that I didn't understand.
Which Sibelius sound set do you use?
VE_SoundSet_SpecialEditionPLUS_v5.2
VE_SoundSet_SpecialEdition_v5.1
VSL_House_Style_Sib7_v.2.1
VE_Optimizing_Sibelius_Playback_v4.5
Sibelius Ultimate Version 8.5.1 build 659
Windows 10 up-to-date, 12G of RAM
For the two channels you describe, you list three presets for each. One Vienna Instruments (Pro) channel can only load one preset at any particular time. So which preset did you load now?
I have enclosed two audio examples (WAV files) to illustrate the problems, both from a Mozart work with flute and bassoon. In MOZART FLUTE TRILL.Wav, the flute plays correctly the notation in SIbelius for 4 seconds from the beginning. Then the flute notation contains trill mark, and some strange things happen. The flute in VEPRO/VIPRO not only plays the trill mark, it also plays all subsequent notes with trills until 8.5 seconds from the beginning. At this point, 8.5 seconds from the beginning, the flute part contains a second trill mark. Here, VEPRO/VIPRO stop playing trills on every note.
In addition there is a second audible problem in this audio file. At the first trill mark (4 seconds from the beginning,) there is a sudden, noticible increase in reverberation in the flute part. This increase in reverberation continues until the second trill mark (at 8.5 seconds from the beginning.) This additional reverberation is inexplicable because this recording was made with no reverberation in VEPRO, VIPRO or in Sibelius. In Sibelius>play>perfeormance, the box marked "Use Reverb' is not checked.
To make this recording of the flute part, a loaded two presets into Channel 2 in VEPro/VIPro: Sibelius>Special Edition 5.2>SE Vol. 1>11 Woodwinds>025 Flute 1; and Sibelius>Special Edition 5.2>SE Vol. 1>11 Woodwinds>025 Flute 1+. The result was trills played on many notes where no trills were notated in Sibelius. When I tried loading ONLY Sibelius>Special Edition 5.2>SE Vol. 1>11 Woodwinds>025 Flute 1. the flute played no trills at all.
I also recorded the bassoon, loading two presets into channel 3 in VEPro/VIPro: Sibelius>Special Edition 5.2>SE Vol. 1>11 Woodwinds>315 Bassoon; and Sibelius>Special Edition 5.2>SE Vol. 1>11 Woodwinds>315 Bassoon+. The trill problem and reverb problem were identical with the flute part. At 41.5 seconds from the beginning, there is a trill marl notated in the bassoon part in Sibelius. From that point to the end, the bassoon plays with audible trills on every sustained note, and with greatly increased reverb. Once again, I used no external reverb.
I got conflicting advice on the forum. One post suggested that I load both the Special Edition preset and the Special Edition Plus preset for each instgrument. Another post says says to load only one preset for each instrument. However, if I load only one preset--the Special Edition preset--the instrumenty plays no trills. Please indicate exactly which presets I should load into VEPro/VIPro so that the flute and the bassoon play only the trills that are notated in Sibelius, with no added reverb. Should I load the two flute presets on two different channels. and the two bassoon presets on another two different channels--and change the channels in Sibelius to the same numbers?
If you want to, you can send your Sibelius project and Playback Configuration (xml file and files in the data folder) to support@vsl.co.at and I will take a look at your files. I will return to the office on Monday.
