It is an interpretation of my old avatar: a picture I took of a local great blue heron. Apparently, when downsized, it looked like a "elk-warthog-unicorn thing" to her "tired, weary eyes".

I've decided to publish a version of my rejected PhD project proposal on my wiki, and place it under the CC BY-SA 4.0 license. Enjoy!

Okay. It's live. introducing: the candy crystal rainbow codex: https://pbat.ch/codex/
And the code: https://git.sr.ht/~pbatch/codex
more transmissions to come.

Okay so #introductions
Hello. I'm @paul. I'm a musical hacker and sound designer interested in teaching computers how to sing. I spend most of my time working on software projects related to the field of computer music.
Some topics that amuse me:

#mead
#grids
#monome
#android
#generative
#HCI
#powersoftwo

The Zim Kingston cargo ship lost 40 containers just outside of Vancouver, now it's anchored near Victoria and it's on fire.. And the storm has not even begun.

Tonight's freshly baked baguettes! Should be still warm by dinner :)
#looptober day 23
Thinking about: jon hopkins soundtracks, 5-voice chord progressions.
Finally, there's a store in my area that carries Boylan's Birch Beer. It's been so hard to find anywhere!
List of princess bubblegum outfits: https://adventuretime.fandom.com/wiki/Princess_Bubblegum/Outfits
I want to know the person responsible for picking out the outfits for princess bubblegum and Marceline the vampire queen.

thinking about: articulation. heptapod B by johann johannsson. diphones.
but mostly, this is me messing around with the new envelope capabilities I added to the gesture synthesizer controlling the vocal synthesizer.

What do people use their grid controllers for? All I know is that I see things lighting up, but I have no idea what people actually do with them. How do I get from a colourful grid to music?
(There's one for sale at my local pawn shop, but that's not why I'm asking.)

Working title for a edutainment computer music radio drama podcast I may never actually make:

Check out the first prototypes of what will likely be our first line of original action figures!
Based on Commando Cody from Radar Men from the Moon, he's a 3.75" hand made action figure with 4 points of articulation, a jetpack, and a raygun.
The prototype is a little too flashy in the color scheme department (the copper color + the clear coat makes him too shiny) but IT LOOKS SO COOL.
All my #looptober tracks made so far have been uploaded to a #funkwhale instance under a CC0 license:

All of these were procedurally generated using my custom engine with a scheme scripting interface. You can find the corresponding code for each looptober here:
The string ensemble kind of sound like ondes martenots and/or theremins at the time. Happy accident. Certainly adds a supernatural charm to it. I initially wanted more realistic strings to give it tragic romance vibes. But, I did not have those sounds. Probably for the best though right?
Oh, the melody is very much inspired by that "O Willow Waly" song sung in the Haunting of Bly Manor.
I haven't had many opportunities to write string quartet arrangements, so that was the challenge for me.
I started with the melody and the timbre of the distance singing voice (more reverbed voice than dry). I wanted her to sound behind.
The string sounds are somewhat narrow bandlimited square waves. Initially, I was going to used bowed string models, but didn't want to bother tuning it.
The harmony and arrangement was very loosely inspired by Milowda from the expanse OST. I started out with block chords, than gradually tried dropping in more contrapuntal melodic lines.

Thinking about: O Willow Waly, Milowda, Lighthouses, Ghost stories.
Some say that to this day, you can still hear her calling from the lighthouse tower...

I feel this could be relevant for LURK & friends:
Call for contributors - Chiptune studies reader:
"We are excited to announce that we are seeking contributions for The Chiptune Studies Reader, an interdisciplinary peer-reviewed and edited volume on chiptune - or 'chipmusic' and 'micromusic' as it is also known - which we intend to publish through Oxford University Press.
The invitation to submit an abstract is open to scholars in the arts, humanities, and social sciences, as well as chiptune practitioners and fans."

The ramps output by the ramp tree aren't always linear. Behaviors are functions that can be applied to the ramp to rescale it. This allows things like exponential line segments to happen.
The core data structure that powers Gest is what I call a "ramp tree". This provides rhythmic subdivisions of a beat.
How it works is: a phasor (periodic ramp signal) goes into the tree, and then this phasor signal is dynamically resynthesized and sped up / slowed down based on the structure of the tree. What comes out the other side is a series of 0-1 ramps of varying length relative to the input phasor.
Normally, the output of the ramp tree is used to interpolate between to values like you would a line segment. However, if you skip that step and just use the ramp tree output, you can use this as an envelope signal!
Turning my gesture synthesizer into an articulation engine tonight :)
