Hey hey,
does anyone have an example of a "turing machine sequencer" implemented in 
Csound? I think I get the basic idea, but I'd like to confirm that and don't 
think I'm skilled enough to read the original source code.

Best wishes and thanks for any pointers,

Jeanette

Many thanks Dave, this gives me a good idea and maybe I can incorporate
it into my project.

Best wishes,

Jeanette

Thanks Partev, I'll start with Wiki. I didn't try that because of the 
confusion between the computer scientist terminology and the sequencer usage. 
:)

Best wishes for 2022 (if you observe it),

Jeanette

Hi Jeanette,

I wrote some articles on Linear Feedback Shift Register in Csound. They are written in Japanese, but csd files are annotated in English.
I created basic 8 bit LFSR from scratch because lfsr opcode does not have control of bit shift frequency (it is krate in lfsr opcode).
Basic concept is from Music Thing Turing Machine and Doepfer A-117, though I did not reverse-engineered the modules.
Attached csd is the final code with Cabbage GUI. I hope you find it interesting.

Hello Tetsuya,
many thanks, I think this will be further great guiding in my undertaking. 
Thank you for sharing this code!

Best wishes,

Jeanette
