some extra info:
The main pad sounds were created with a Proteus2000 controlled by an arduino through midi.
The code for it isn't very complex (nor is it optimized as it was just an experiment) and here's what it does.
First a semi-random sequence is created with notes from a scale, in this case I used C, D, E, F, G, A, A#.
The sequence is 16 measures long and each measure has a duration of 4. The notes can have a length of
1,2,3 or 4 and this length is also picked at random when creating the sequence (and stored as a seperate
sequence). However, with each measure having a duration of 4 this is not entirely random. For example if
the length of the first note happens to be 3 than there can only be one note added to the measure with a
length of 1. If it is 2 than it could be another note with a length of 2 or 2 notes with a length of 1 so the
total length will always be 4.
After the sequence is created it is played back and looped untill a button is pressed and then a new sequence
is created. For Phormium Tingles it is just the same sequence repeating. When it is played back notes are
shifted up or down 1 octave (or not) at random to have a bit of variation. Also at the start of each measure
a bass note is generated (with a length of 4). These bass notes also play the same sequence, but slower, and
are shifted down 2 octaves. (yay, fractals)
// ----------------------------------------------------------------------------------------------------------------------------------
// play and repeat the sequence untill the reset button is pressed
while (digitalRead(buttR_pin) == 1) {
notes_left = 4;
measure = 0;
I like this type of gentle aleatoric composition as well. Everything makes perfect musical sense, but you're never sure how it's going to go. An endless, but logical progression....

thanks, glad you enjoyed it.
Yeah aleatoric music is interesting, the tricky part to me is having some randomness but still keep it musical. Full on random can be useful but doesn't sound
very musical by itself. Limiting the amount of notes already helps but can still sound somewhat too chaotic, although it works great together with something
that repeats, the brain usually likes some repetition. For this 'experiment' in particular my initial goal was just to have something that creates a sequence at
the press of button. I wanted some variation in note lengths but again total randomness can quickly sound less melodical so I limited that to some degree.
Originally I had it running much faster and it was more obvious, with the long drawn out and layered notes it becomes a bit less noticable.
I had another idea yesterday which I tested and seems to work but I need to mess around with the code a bit more. so stay tuned!
I just set up my studio here in Durham and the first sound was e-m radio with this track. It's beautiful. Congratulations... _________________ --Howard

The usual Space Odyssey serendipitous tones with a tincture of "alien intervention" near the end. PHOBoS does it again! _________________ I'm an aspiring artist, and I also aspire to inspire! =D
