hey - if you read the blog it says sounds, but more helpfully, if you drop the sysex in C^ it will show you in the bottom left corner what is contained within the sysex - it says 10 sounds for this file ! The device also receives sysex from any menu position, it needn’t be waiting, but i think the sounds will be placed where they were originally saved as each sound contains a reference to the slot it was in !
