I had a really great day today.

Deleted a ton of code and added a bunch of functionality.

New release soon, probably tomorrow!

Anyone out there still kicking the tires? :slight_smile:

I’m just about to test it out. Will be focused on MIDI - experimenting with using an RPi to run my grids. Looking forward to checking it all out - thanks so much for sharing your work!

Hi everyone. Since this thread, last year I started on a 2.0 branch of pippi which was a total rewrite (except most of the tune.py module) for python3 and a totally different model based on standard python ideas like SoundBuffer and Wavetable data types with operator overloading for expressive manipulation.

Anyway, it’s buggy but I just released alpha 9, and started on beta 1, which is mostly focused on fixing bugs and writing docs.

The project is still on github: http://pippi.world

If you are a python person or otherwise have time to play around with this I’d appreciate beta testers still! Thanks!

Yep, the wavetables.polyseg generator isn’t done. (Working on a concise way to compose wavetables from other wavetables.) There’s a failing test in there on purpose to remind me to finish it! Glad to see all the other tests are passing on your platform. :slight_smile: Looks like linux based on the path to your home dir, do you mind sharing what distro you tested with? (oh duh also the word linux is in your hostname, also a clue haha. so probably running in a vm?)

Thanks!

That’s offputting though (including failing tests in alpha/beta releases)…

Better to call it out in the readme, or disable the tests, or something else?

Making some progress on astrid, the interactive / performance front end to pippi:

Tests are:

  • Granular processing of mic input (buzzing on a tbone mouthpiece & clinking a coffee mug)
  • Simple mic record/playback test (counting)
  • Synthesis & polyphonic playback / note scheduling test
  • Sound file playback (Torvalds pronouncing linux)

Oh! Sorry. You posted the cmd you used.

Try this instead:

make clean build

You can also just:

pip install pippi
#56

Also, the best way to install / build from source is still to checkout the repo and:

pip install -r requirements.txt
pip install -e .

@shreeswifty Hopefully one of those paths works for you, if you have some bandwidth to test again please let me know how it goes! Thanks so much for helping me test this!
