### Description

Live Music Coder M^2 : Music Composer by Mathematics This application calculates note number and play its sound in real-time operated by using command line style interface. It looks like Unix but also has new feature of our one-line-coding rule and reversed scroll. Try to play music by a sequence of numbers and formula instead of a score! We make an effort at simple and real-time operation. You can do all operation of the parameter change and parameter etc. while playing music in real-time. [function] define parameters describe formula start/stop sequencer view data list save/load/delete parameters view current status show help [calculator] 1) user parameter r1,r2 : array of note number - note : 4 octave from 1 to 48, except for them are silence. 1tick = sixteen note. - sound: sine wave which decreases envelope , no volume controller. - tempo : 40 - 160 BPM a0, b0, c0, d0 : 4 output sound channels. calculate each formula. - simple example define parameters: r1=1 3 5 6 r2=13 15 17 a0=r1 b0=r2 output A track : C1 D1 E1 F1 C1 D1 E1 F1 C1 ……. repeated output B track : C2 D2 E2 C2 D2 E2 C2 D2 E2 …….repeated as sixteen note 2) operator +, -, *, / , % ( add, subtract,multiply,divide,residue) 3) controller ?,:, !, 〈, =, 〉,| (if, else, not, smaller, equal, larger, separator) 4) embedded parameter q : tick. increment this per sixteen note. s : slider value (0~99) x : random value (0~range) range:0~99 v1,v2,v3,v4 : store the value before separator(|) and branch(?,:), then reference in the expression. (1|2|3|4| : v1=1, v2=2, v3=3, v4=4) a1~8, b1~8, c1~8, d1~8 : history of a0, b0, c0, d0 (a0-a1-a2-a3-a4-a5-a6-a7-a8) 5) formula samples ** First of all define the array (sequence) "r1/r2" of note number and then calculate them in the sound track (a0, b0, c0, d0). r1=1 3 5 6 8 10 a0=r1+1 : 2 4 6 7 9 11 …. a0=r1?〉5+12 : 1 3 5 18 20 22 …. (if r1〉5 then r1+12) a0=r1?〉5+12:12|v3 : 12 12 12 18 20 22 …. (if r1〉5 then r1+12 else 12) a0=r1?〉5|24:12|v4 : 12 12 12 24 24 24 ….. (if r1〉5 then 24 else 12) ---------- r2=1 0 1 1 2 0 2 2 (0: rest) b0=r2 1 0 1 1 2 0 2 2 1 0 1 1 2 0 2 2 … ---------- a0=x (simple random music) [button] start/stop : start/stop music list/load/save/delete : list data file, load/save/delete data status/view/help1/help2 : view current status, view selected data int the list, show help1/help2 type : change keyboard clear : back cursor or clear-all-parameter enter : execute command r : define note number (switch r1/r2) a : select (a0,1,2,3,4,5,6,7,8) b : select (b0,1,2,3,4,5,6,7,8) c : select (c0,1,2,3,4,5,6,7,8) d : select (d0,1,2,3,4,5,6,7,8) a0: describe formula of sound track 1 (left operand only) b0: describe formula of sound track 2 (left operand only) c0: describe formula of sound track 3 (left operand only) d0: describe formula of sound track 4 (left operand only) a1-8: reference history of output note number of track1 (right operand only) b1-8: reference history of output note number of track2 (right operand only) c1-8: reference history of output note number of track3 (right operand only) d1-8: reference history of output note number of track4 (right operand only) v : select (v1,2,3,4) oct : switch octave Please visit our website! http://iphone.iiv.jp/
