I read this function it's able to save one single or multiple instruments
with relative effect and mixer setting but I don't have obtained the request
istruments it's saved correctly but no mixer and effect setting.
When you start GS3 it will start with your default performance, not with the settings you had when you saved it. When GS3 is up and running, go to FILE and open the file you saved. After this performance opens all your mixer settings should be as you saved it.
Depending on how you are working, you can make it easier for yourself if you save a performance with all the settings as you wish them as a DEFAULT performance. Then every time you start GS3 this will come up. If however you often change your settings, it is better to SAVE AS, and leave the default performance as it is.
You should also remember that your settings in your sequencer will change the settings in GS3. I work with a templete same both in GS3 and my squencer. So when I load GS3 then the sequencer, both are having the same setups. It all depends how you are working.
The .GSI file has effects and other information "inside it", and that is not displayed in the insert section of GS3.
For example, if I load one of the GS3 sample content .gsi files with embedded effects (like the Westgate Studios "WS-Trumpet.gsi"), I can hear the effects, but the effect is not part of the "normal" DSP Station window (the top window). However, in the Quick Sound window, I DO see an "impulse" instrument (Medium Hall-Back Center), and it has a small gray "FX" icon next to it.
