#sapf — Public Fediverse posts

ive fixed the zctl function in cross-platform #sapf, which is supposed to turn a ZRef into a control signal but was completely broken.

it is useful in OSC workflows, e.g.:

; store "/knob1" OSC data in the "cutoffknob" ZRef
0 ZR = cutoffknob
"127.0.0.1" 9901 "/knob1" \args [args head cutoffknob set] oscmap

; use it to control filter frequency
55 0 saw
(cutoffknob zctl 0 1 20 20000 linexp) 0.2 rlpf
0.2 *

ive moved the sapf.el repo to codeberg and also added some handy little functions to get help, clear the stack and clear the sapf process buffer 🥰

kick drum synthesis (??) #sapf

last year i added to cross-platform #sapf "oscmap", a preliminary Ref-based implementation of OSC input. this was simple to implement, but not very flexible.

ive now rewritten oscmap to use callback functions, similar to how SuperCollider OSCFuncs work. this is a lot more powerful and should allow far more diverse OSC handling logics :)

cross-platform #sapf is now a little more international as i fixed an issue that prevented non-ascii characters from being entered in the REPL.

it may not be "unicode-aware" exactly but the very simple parsing rules permit using unicode in identifiers. so now you can name your stuff with ääkköset, CJK, emoji and whatnot. go wild https://github.com/ahihi/sapf

#looptober 07. some #sapf for a change

I just registered for SAPF 2 www.start.gg/sapf #SAPF via @startgg.bsky.social

"you should get a faster laptop to make music"

no. you should get a slower laptop

gonna try building #sapf on the eeepc :3

ive added vterm support to my sapf.el - this enables much faster evaluation of multi-line code blocks than the previous comint implementation :)

not sure if the slowness was even an issue outside macOS and/or 12 year old hardware, but either way this fixes it! https://github.com/ahihi/sapf.el #Emacs #sapf

hacking on OSC support for cross-platform #sapf

fixed some memory bugs in cross-platform #sapf :)

- aab, aabb and bab no longer produce wrong results when they trigger a resize of the stack vector
- ^D now exits cleanly instead of segfaulting

Windows support is now merged! 🥳 https://github.com/ahihi/sapf #sapf #LiveCoding

Windows support is coming to cross-platform sapf, thanks to the work of chairbender! https://github.com/ahihi/sapf/pull/14 #sapf #SuperCollider #LiveCoding

#sapf now reads audio files on linux! #LiveCoding

so close and yet so far #sapf

#sapf on Linux: FFTs now implemented with fftw -> wavetable oscillators like "saw" work 🥳 #LiveCoding

ive published my cross-platform #sapf fork at https://github.com/ahihi/sapf !

highly WIP, but it does currently start and play audio on Linux. see the issues tab for some things that need doing, in case you know some C++ and would like to help :)
