wad

strikingly similar to WAD - https://github.com/rserota/wad

Everything is available already. If you want to see how it works just follow the instructions: https://github.com/rserota/wad#pitch-detection

I hacked on this a while ago, and the best libraries I found were one called Wad for playing notes and applying effects, and another called Teoria for building chords and intervals and so on. I was hindered by not having any idea what I was doing but here's what I came up with: http://www.aphall.com/random/audio-test/ (clicks weirdly in firefox, no idea why.) Libraries: Wad: https://github.com/rserota/wad Teoria: https://github.com/saebekassebil/teoria

This application is intended for live performance, so it uses a few keyboard controls to control the application state. These controls aren't intuitive, so you'll want to read/remap them in the gear-menu. If you're unclear on what live-looping is, or how to use this application specifically, check out the help menu (the big question-mark button) for a brief rundown. Also note that this application depends on the Web MIDI API, which, AFAIK, is only available in recent versions of Google Chrome. Some features should work in other browsers, such as testing the synthesizers and using microphone input, but if you want the intended experience, you'll need to use Chrome. Anyways, I hope you alls have fun with this. It was built with Wad.js, a Web Audio framework that I wrote. Check it out on github: https://github.com/rserota/wad.

Beep.js really isn't a synthesizer, it's more of a step-sequencer. You might want to check out WAD.js, which is more concerned with synthesizing sounds than scheduling them (it has filters, LFOs, other effects, etc). https://github.com/rserota/wad. Full disclosure, I wrote WAD.js. and btw it's totally possible to make well-timed music with web-audio. I've got a midi keyboard hooked up to web-audio based looper, and that's what I use as my primary instrument these days for practicing. It works fine for me.
