| 15 | +========================== |
| 16 | + |
| 17 | + |
| 18 | +A music maker for the Game Boy. |
| 19 | + |
| 20 | + |
| 21 | +Introduction |
| 22 | +------------ |
| 23 | + |
| 24 | +Bleep is a music creation program with piano roll interface. |
| 25 | + |
| 26 | +It lets you jam out chip music really quickly, and it writes directly into save |
| 27 | +memory, so your work is saved automatically. This is not the final version, but |
| 28 | +I was reminded the Game Boy dev compo was going on, so I'd. |
| 29 | + |
| 30 | +This is just a prerelease, the final will include source code, and add many |
| 31 | +missing features to the editor. |
| 32 | + |
| 33 | + |
| 34 | +Controls |
| 35 | +-------- |
| 36 | + |
| 37 | +Up/Down/Left/Right (tap) = move cursor once |
| 38 | +Up/Down/Left/Right (hold) = move cursor quickly |
| 39 | +A (on empty cell) = draw new note. hold A and drag to make longer/shorter notes. |
| 40 | +A (on current note) = truncate/remove note, draws new note if dragged. |
| 41 | +Start = play from beginning |
| 42 | +Select + Left/Right = select channel |
| 43 | +Select + Start = play from current measure |
| 44 | + |

| 54 | +| | | d | |
| 55 | ++---+-----------+---+ |
| 56 | + |
| 57 | +a = Piano |
| 58 | +b = Music Sheet |
| 59 | +c = Channel Selector |
| 60 | +d = Measure Counter |
| 61 | + |
| 62 | +-- Piano -- |
| 63 | + |
| 64 | +Visually represents the pitch of the notes in music sheet |
| 65 | + |
| 66 | + |
| 67 | +-- Music Sheet -- |
| 68 | + |
| 69 | +This space represents the music score itself. |
| 70 | + |
| 71 | +The grid is horizontally divided into 4 notes per beat, 4 beats per measure, |
| 72 | +for a total of 2048 notes (or 128 measures). The grid also divided vertically, |
| 73 | +one row per note, separated into octaves. Sharp notes are shaded differently to |
| 74 | +help you out. |
| 75 | + |
| 76 | +You can place notes here to make music. Channels are monophonic, so each column |
| 77 | +of the music sheet can contain a single note. |
| 78 | + |
| 79 | +- Press the directions to move around the music sheet. |
| 80 | +- Press A to place notes or delete notes on the music sheet. |
| 81 | + You can hold A and move around to make longer/shorter notes. |
| 82 | + |
| 83 | + |
| 84 | +-- Channel Selector -- |
| 85 | + |
| 86 | +There are four channels. |
| 87 | + |
| 88 | +P1 = Pulse 1 |
| 89 | +P2 = Pulse 2 |
| 90 | +W = Wave |
| 91 | +N = Noise |
| 92 | + |
| 93 | +There are currently preset instruments for each of the channels, that can't be |
| 94 | +changed. In the final release this will be customizable. |
| 95 | + |
| 96 | +- Pulse 1 is "flute"-like. |
| 97 | +- Pulse 2 is "piano" or "harp" like. |
| 98 | +- Wave is initialized to a 4-bit square wave: |
| 99 | + |
| 100 | + 00 00 00 00 00 00 00 00 00 00 00 00 00 FF FF FF |
| 101 | + |
| 102 | +- Noise is sort of "snare"-like. It also doesn't have a conventional pitch. |
| 103 | + Currently you can affect what "divisor" is used by the noise channel |
| 104 | + which uses the note number modulo 8, but that's all at the moment. |
| 105 | + |
| 106 | + I plan to make noise use a customizable drumkit |
| 107 | + (where each note is a different drum), but it's not there yet. |
| 108 | + |
| 109 | +- Hold Select and press Left/Right to switch the channel shown in the editor. |
| 110 | + |
| 111 | + |
| 112 | +-- Measure Counter -- |
| 113 | + |
| 114 | +Shows the current measure number being viewed in the song. |
| 115 | +There are 16 notes, or 4 beats per measure. |
| 116 | + |
| 117 | +- Hold Select and press Start to play starting from the current measure |
| 118 | + |
| 119 | + |
| 120 | +Known Issues |
| 121 | +------------ |
| 122 | + |
| 123 | +- If you drag a note that crosses a 256-byte boundary, it will currently |
| 124 | + stop redrawing the note preview until you let go of the note. |
| 125 | +- Note placement acts funky at column 2047, the final column of the song. |
| 126 | + |
