Intro video:
This software is our personal and romantic way to celebrate the 40th anniversary of the debut in 1982 of the most successful computer ever. Without the C64 there would probably be no Orastron.
A-SID allows you to turn your C64 into a wah effect. No hardware modification is required, but you need to build yourself one or two adapter cables and copy the program to a cassette. Instructions are given on the product web page.
Otherwise, if you are not a lucky owner of one those marvellous machines, you can use our free VST3 that gives you the possibility to experience A-SID on modern computers as it emaulates the original analog filter.
If instead you use a Mac (we haven't ported the plugin yet) or are totally debauched to the point of not willing to even download the damn thing, you can just try an online demo on the product web page.
Creating this software has been a fascinating journey that absorbed an immense quantity of energy and time. We don't ask for your money or your data, and we are happy to release (almost) everything as open source software. We're simply happy if you like it.
We would really appreciate if you could spread the word about A-SID and Orastron with friends and on social media, forums, etc. Bluntly put, we'd love to make innovative premium consumer products, but we first need an audience for that to be economically viable.
Features

- 400 Hz to 2.2 kHz cutoff frequency on VST3 and newer C64s with MOS 8580 SID chip, some other unpredictable range on older C64s with MOS 6581;
- Sinusoidal LFO with 256 output values;
- Circa 0.4 Hz to 25 Hz LFO frequency range, a little bit swingy on C64;
