Hi Omnimaga !
Today I present you a projet took me 1 week of work
It's a Music editor on calc (1 channel I'm not a monster too )



The column:
Line | Note in decimal | Note | Octave

There is the keys:
"trace" octave -1
"graph" octave +1
"2nd" test the actual note
"mode" insert a line
"del" ("suppr" on french calcs) delete the line
"+" add a line in the end
"-" delete the last line
"up" and" down" to select a note
"left" and "right" to change the note
"ln" load a song ("SONG.8xp")
"sto" save a song ("SONG.8xp")
Tempo:
"4" and "1" +/- 100
"5" and "2" +/- 10
"6" and "3" +/- 1

"enter" play/stop the song (need a long press to stop)

SNOUD.8xp Is the program
SOND.8xp Is a bad apple music sample
