1Tracker can produce tracks compatible with the Electric Duet format (playable through the Apple//e speaker or MockingBoard).
The speed column can take the values (slow) 1, 2, 4, 8, 16, 32 or 64 (fast).
Notes are entered by typing on the keyboard; the allowed range is A-2 to G#6. The octave can be selected using SHIFT+Number.
Please be aware that notes will keep sustaining unless told to stop. Pressing the key “a” will add an “R” mark that stops the note playing (so typically, your score will consists of slow speed note followed by fast speed R).
Use the key F5 for playback, and F3 / F2 to load and save in the 1Tracker format. Use F8 to export to the “.m” format supported by 8bit-Unity.
NOTE: Do not leave empty rows! Add “R” in all places where a note is not playing!
