En la propia pagina del programa tienen un tutorial con fotitas para el rapido aprendizaje:

Por cierto. Nueva versión ya compatible en lectura/escritura con las M3SD y SCSD, entre otras cosas:
Features:
* added a "cln" button that clones the current pattern
* column selection: make a selection over the columns you want to select and press the "sel" button. This expands the selection to the complete column(s). Without an active selection, the column under the cursor is selected.
* live recording: press play in record mode and play
* added del and ins buttons to the pattern screen, removed the del button from the keyboard
* new settings tab
* left-handed mode (D-Pad swapped with ABXY and LR swapped)
* in list boxes, clicking below/above the "scroll thingy" scrolls down/up one page
* you can now tap on the song name / filename to change the name
* you now have to touch the spash screen
Fixes:
* Writing is now supported on M3SD and (hopefully) SCSD, because I switched to Sata's fat lib from rain r14
* moved to devkitARM r18 (general karma increase, perhaps better m3 compatibility)
* wav loading was broken. fixed it and made it secure.
* looping behaved strange sometimes. fixed that.
* list indices are now in hex, to be consistent with the instrument column in the pattern view and with FT2
