Like the sound of those old analog synthesizers? Want to play with one on your own time, at your own place, for as long as you want, for FREE? Here is where your wildest Moog dreams come true. You can become an electronic recording artist or just make some cool, trippy sounds to listen to on your mp3 player. All you need is a computer!
It's all done through the magic of a free circuit simulator called LTSpice. Now I know you're probably saying "Gee willikers, Tyler, I don't know anything about running a circuit simulator- that sounds HARD!". Don't worry, Bunky! It's easy and I'll give you a few templates to start with and modify to make whatever weird noises you want.
Not sure it's worth the effort? Here's a link to a ready to play sound file (it is made from "composition_1.asc" in step 7 of this 'ible) that you can try out. I converted it from .wav to mp3 to reduce the download time. http://www.rehorst.com/mrehorst/instructables/composition_1.mp3
There's some low bass in it the sound so listen with headphones or good speakers.If you like what you see, vote for me!
Note: I have attached schematic files for LTSpice that you can run on your computer, but for some reason when you try to download them the names and extensions get changed. The contents of the files look OK, so after downloading the files just change the names and extensions and they should work. The correct names and extensions are shown on the icons you click to download.
