Retro AS-1 Image

The Retro AS-1 is a full featured programmable analog synthesizer for Macintosh and PC computers. Taking a modular approach you create and link modules of oscillators, envelopes, filters and LFO sections. The results can create stunning analog synth sounds in a clean 44.1kHz digital environment. The AS-1 is fully MIDI equipped and works with sequencers and MIDi controllers. However it has an on-screen keyboard and can also be triggered from the computer keyboard.

New patches can be stored on your hard disk for a virtually unlimited amount of user patches! The AS-1 has such extensive and complete editing and parameter control that it could intimidate, even baffle some users. Be sure and try the FREE DEMO version and see if the professional Retro AS-1 polyphonic synthesizer is for you!

I installed this in 1998. My internet friends got hold of a copy and serial number. The serial number didn't work, but--miraculously--I figured out a correct serial number from the wrong one and shared it with everyone. I'd love to use this again, which is how I found this page, but from what people say, it's not going to work with Windows 7. Too bad.

It sounds wonderful. I have both versions 2.0 and 2.1 or 1.20 and 1.21,cant be too sure of the number. You will have to keep an old desktop to run Windows 98 for it to work. To be honest, the very first version sounds much better than the later one which sounds lounder but harsher. I think I am the only holder of this synth in my country of China.
