Here’s a short example for the agrument not to pull from upstream sources. I recently edited the Karoryfer Black and Blue Basses (source), without the edits these issues would occure:
- License is CC-0, so editing is fine. I would name the creator anyway.
- Current Zynthian implementation seems to just look one level of sub directories. Since then this soundfont wouldn’t be recognized at the moment. Before that implementation changed it would have been recognized, but including all the unusable control- and mapping script in sfz format in the program sub directory. tl;dr: It wouldn’t load at all.
- It would sound very muffled, because the cutoff=250 is recognized by sfizz, but the var1* and var2* opcodes modulating that filter in the controls/filter.sfz is not supported. Hence static filter at 250 Hz.
- It has 11 articulations, including keyswitched patches including all of these. This is fine for desktop use, but not so much for a tidy groovebox patch list.
- The controls are recognized by zynthians autoparser, but not in a usable order and without the keyswitch control. So you must read the script to figure out that there are keyswitches.
- It contains gui/aria related files which cannot be used by the sfz engines in zynthian.
