Lens 2


LENS is actually a BASIC program which manipulates the registers of the ALF card by PEEKs and POKEs.

The ALF synthesizer card contains an Intel 3-channel timer chip (sound source) and 3 16-bit DACs for volume and envelope control. This allows 3-part harmony with a square wave oscillator. Not sophisticated, but there was some clever music written for the device.
