Just for fun, I made my own synthesizer keyboard app for the iPad and iPhone. It’s all homebrew stuff. I created my own oscillator and ADSR envelope routines and just rely on the OS for audio sample callbacks. It can play back any of the following waves: sine, square, triangle, sawtooth, pulse, and noise. If you’re familiar with old-school game and computer systems, like the NES and C64, you’ll recognize some of these sounds.<\/p>\n

I’ve previously demoed the synth music player<\/a>, which uses tracked files for note playback. This is the first time I’ve hooked up the synth code to a UI system so that you can play music directly.<\/p>\n

This keyboard runs on iPhone and iPad. Here are a couple of screenshots.<\/p>\n

And here’s a demo of me playing with the app on the iPad:
