A-SID: turn your Commodore 64 into a wah effect #VintageComputing #Music
A-SID allows you to turn your Commodore 64 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
Otherwise, if you are not a lucky owner of one those marvelous machines, you can use the free VST3 that gives you the possibility to experience A-SID on modern computers as it emulates the original analog filter.
If instead, you are don’t wish to download it, you can try an online demo.
Features
Resonant bandpass filter 6 dB/oct;
Smoothing-free (nice steppish behavior);
16 selectable values for center cutoff, LFO amount, and LFO speed (via joystick on C64, and mouse/touch on modern rubbish devices);
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;
Modern, interactive, and epilepsy-inducing hi-res mode 320×200 pixels graphics with visual feedback and using 11 colors (freely resizable in VST3);
Support for one expression pedal on C64 (interfaced as a paddle) as an extra source of modulation, with calibration procedure at boot.
