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.
