The 2soniq was created by Manila Gear in April 2017. It gives the Apple IIgs stereo sound, instead of the usual one.
Each of the 32 oscillators available in the Apple IIgs’ Ensoniq Digital Oscillator Chip (DOC) can be assigned to play on any one of 8 output channels. The 2soniq card unlocks 2 of those channels. See also the 4soniq.
To enjoy stereo channel sound with the 2soniq, you will need two powered speakers (e.g. one set of 2.1 computer speakers setup up as Left and Right). Almost all software written for the IIgs supports stereo sound.
Project Status: Complete. In production. Actively sold by Manila Gear and ReActiveMicro.
