This is starting to sound like a really impressive app for the DSi.
Can you spot the apps being used?
Another QY10. Not always popular, but some like to circuit bend these.
An SU10 for an okay price.
And finally a Pocket Music – Nintendo Game Boy Advance GBA DS Lite, which is very cheap at the moment.
BM2’s Drum Machine Instrument. Here’s what you need to know …
The iPhone and iPod Touch version will come up first, and a native iPad version should follow soon after. It will be released this summer.
More at the Intua Forum.
Here’s an interesting new music app. I think that the concept’s great. I might need to try this one out.
Here’s the app description:
ive 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.

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
+, -, *, / , % ( add, subtract,multiply,divide,residue)
?,:, !, ,| (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 (ax, bx, cx, dx).
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 ….
a0=r1?>5+12:12|v3 -> 12 12 12 18 20 22 ….
a0=r1?>5|24:12|v4 -> 12 12 12 24 24 24 …..
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 …
