The 4soniq was created by Manila Gear in April 2016. It gives the Apple IIgs four separate channels of 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. One 4soniq card unlocks 4 of those channels. Pair it with a second 4soniq card to unlock all 8!
To enjoy four channel sound with the 4soniq, you will need four powered speakers (e.g. two sets of 2.1 computer speakers setup up as Front Left, Front Right, Surround Left and Surround Right), and the appropriate software.
Four channel sound is now supported in Ninjaforce’s Kaboom! and has been tested successfully on modified versions of Ninjaforce’s NinjaTracker * and Sheppyware’s AmperSound GS. See the downloads section for more software.
For software that does not support four channel sound yet, the 4soniq functions equally well as a two channel stereo card.
