* [Audio 6/?] Build Soundfonts and the Soundfont Table * Improve lots of error messages * First suggested changes * Make audio build debugging more friendly Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com> * Some fixes from MM review * Make soundfont_table.h generation depend on the samplebank xmls since they are read, report from which soundfont the invalid pointer indirect warning originates from --------- Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com>
