VOOG – Moog-style polyphonic synthesizer in Python with tkinter GUI
Body: I built a polyphonic synthesizer in Python with a tkinter GUI styled after the Moog Subsequent 37. Features: 3 oscillators, Moog ladder filter (24dB/oct), dual ADSR envelopes, LFO, glide, noise generator, 4 multitimbral channels, 19 presets, rotary knob GUI, virtual keyboard with mouse + QWERTY input, and MIDI support. No external GUI frameworks — just tkinter, numpy, and sounddevice.

In plain words
VOOG is a polyphonic synthesizer built in Python with a tkinter interface modeled after the Moog Subsequent 37. It features three oscillators, a Moog ladder filter, dual ADSR envelopes, LFO, glide, and a noise generator across four multitimbral channels. Users can play via virtual keyboard, mouse, QWERTY keys, or MIDI input, with 19 built-in presets. The application uses only tkinter, numpy, and sounddevice libraries.

Koelsynth – a simple FM synthesis library2023 · github.com · ▲58This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https://github.com/charstorm/koelsynth/tree/main/examples/si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
