WALLY Osc with 3-way Shape Mod
Posted: Thu Feb 14, 2019 9:49 am
After perusing the "Irregular Sine Waves" thread http://www.dsprobotics.com/support/viewtopic.php?f=2&t=3781 and downloading some of the examples posted there, I opened Martin's PWM-SineGenerator and started messing around with it- and WALLY's the result. Why "WALLY"? Simply because shifting the knob all the way back and forth at a certain speed makes the osc sound like it's saying that- and I certainly didn't want to use any spelling that would get the lawyers from the House of Mouse frowning...
In any case, I'm very grateful for Martin's work, and the 3-way exclusionary switch was perfect for this- what it does is give you the option to adjust the wave shape with the knob alone, the knob plus an external source, or an external source alone. I did modify some of the code (though not greatly), and because I'm not exactly a DSP guru, there's probably inefficiencies galore, but I'm happy with the sound of it- very good for a range of EP and other retro key sounds. Probably not very useful for ultra-aggressive leads or basses, but see what you think.
I included a standard Multi LFO and Martin's "exponential ADSR w/ velocity" for testing external mod sources; I don't think rich and musical results are difficult even without filters, effects, etc. I've had fun making it and playing it- I hope someone else can enjoy it too (improving it wouldn't crush my feelings either)!
