Convert Instruments to Giga4
When you right-click on an instrument or database folder in QuickSound you are given the option to convert
an instrument or group of instruments to the Giga4 format. While this conversion can increase performance
of older instrument formats when used in GigaStudio4, it is not backwards compatible. So, older instruments
converted to Giga4 format will no longer playback on older versions of GigaStudio.
