Hi all! Just a bit of a proof of concept; it's live sound synthesis on the Wii U! This program actually generates all the sounds it makes on the fly. Previous stuff on the Wii U played audio files (mp3s and things) but here I've shown that you can also generate these sounds as you go. It uses kbd.rpl for USB keyboard support (thanks @rw-r-r_0644 for making this possible!) Download Download from HBAS, or have a direct link here Source This app has only been tested on 5.5.1. It needs sndcore2 (although this could be changed) so you're going to need a fairly recent FW to make this work. Usage Once the app starts up, connect a USB keyboard and start playing! The middle row of keys (asdfghjkl) are your white notes; some of the upper row (wetyuop) are your black notes. Z and X control the octave of the notes and C changes the waveform (sine, square, sawtooth or triangle). HOME on the gamepad quits; don't press A! So... Why should we care? It's pretty simple, actually - we can add sound to emulators using the techniques in this program. Generating the waveforms of a retro console no longer requires messing with audio files; you can just make it as you go! Anyway, have fun! I'm pretty tired while writing this, so I'm sure I've missed something. Feel free to ask!
