I'm using a nano biscotte v3 and wanted to create a cusotm sound font. I created sound files in audacity making sure they were mono and wav, I formatted the sd card then pasted all banks onto the sd card at once. However, the new custom sound font does not play, I can hear the font switch, but then nothing plays and the blade does not turn on. I'm not sure what I am doing wrong because I have installed sound fonts before without problems and the new sound files work in 'sabersoundmixer' by plecter.
