I’ve loaded the Mellotron patch onto the internal sd card on my Organelle M. For some reason MKII Flute and MKII Brass are not loading. When I open this patch from USB it works fine, and I’m able to load everything just fine. Might anyone know why this is happening? Thanks! ---

I think it is has to do with case sensitivity. When loading from the SD card, the patch files and folders should be consistent in their case. More here: [Mellowtron isn't loading properly from SD Card](https://forum.critterandguitari.com/t/mellowtron-isnt-loading-properly-from-sd-card/3564) ---
