This piece is a generative modular patch triggered by a gate sequencer pattern of 3 steps on, 1 step off, 1 step on, 1 step off, 4 steps on, 1 step off, 1 step on, and so on to create a representation of Pi.

There is a lot of really great listening here this week. Nice challenge.

As I started to think on pi first thing came up to mind were Euclidean rhythms since they tend to be visualized in circular shapes. From then on it was a very natural step to take rational approximations of pi and then employ divided as Euclidean length and divisor as Euclidean division.

π = 3.141 592 653 5…
22 / 7 = 3.142 857 142 8…
355 / 113 = 3.141 592 920 3…
52163 / 16604 = 3.141 592 387 3…
86953 / 27678 = 3.141 592 600 6…
102928 / 32763 = 3.141 592 650 2…

What I wanted to go for was using these Euclidean rhythms play simultaneously and hoped the small differences past the decimal point would put these sounds out of sync.

102928…
86953…

Pamela’s New Workout at most allows you to enter numbers up to 32 so I started to look into Puredata patches and found some, and I don’t know why but 86953 / 27678 and 102928 / 32763 just seems to be stuck or not working when those values entered into the Pd patch. I didn’t have a way to convert that MIDI into my modular and since Pd is very new to me I got lost along the way.

At this point, I have used two 22 / 7 Euclidean rhythm, while Maths is offsetting one of them, this is how far I’ve gotten by Monday, but I will definitely come back to this idea later on, this made me see Euclidean rhythms in a new perspective and now I’m quite excited about them.

clicked give me a random sound on freesound 3 times, then another 3 times, and another 3 times. these 3 sounds i plugged into protoplasm.
(swedish singing/halloween ambient/kettle sounds)
all the levels i had at 3.14 where possible. recorded for 3 minutes 14 seconds. in audacity i applied lots of fx with values of 3.141, -3.141 31.41 etc finally paulstretched by 3.1 and time resolution of 3.141

I had some trouble with inspiration this week :upside_down_face:

I took some audio samples from this old Open University video which proves why the area of a circle is pi * r^2, some was PaulStretched for texture and little bits used as one shots and through a granular synth.

I used the Digitakt to add percussion (but nothing really related to Pi).

Tau day believers instead celebrate 2*pi (tau) day on June 28th and recognise this number as the proper “circle constant”. 31.4 bars in I gradually up the tempo from 98bpm to 196bpm which moves the song in a more dancey direction, but the shift is a bit messy.

Very kind of you to say, thank you!

I made 4 musical Pi’s and put them together.

3 pi’s are electronic instruments, each playing through the first 32 digits of pi at different speeds. Notes are based on a 1-12 digit scale, so a 0 would be C, a 3 would be Eb and so on.

1 instrument is a drum set that goes through a 10 beat cycle, but how much of that cycle plays depends on the number of Pi that is next. So it would play3 beats, then 1 beat, then 4, then 1, etc.

I programmed all of these into my Synthstrom deluge, then plugged it into the modular for a bit more depth of sound.

This project was constructed on stream! Check my music streams at www.twitch.tv/untilledsound

Here are the specific videos.
Part 1
Part 2

I have a new album! Check it out at www.bandcamp.com/untilledsound

Cheers Y’all.

Here’s mine: https://soundcloud.com/plusch/slice-of-pi-disquiet0376

I put the first few digits of pi into the Transpose and CC slots of Hive’s sequencer. Used the CCs to modulate the Multiply parameter of the sequence clock. For a second voice, I did something similar using Zebra 2.

Per junto instructions, I extended a piece with pi – specifically, I 1) used two one-measure breaks that are based on the first 26 digits of pi, 2) also applied the idea of ‘roundness’ to the piece. It’s in a Rondo form, and one of the sections is actually a round. Based on Bulgarian folk songs, one of them played unaltered on violin near the beginning. Did some sequencing and glitching in SuperCollider, put everything together in Logic.
