A series of video tutorials that covers the Ensoniq Mirage Octophonic Mod. This allows for eight individual outputs, one per voice and filter for the famous Ensoniq Mirage 8 bit sampler.
A few short tutorial videos visualizing the octophonic output mod for the Ensoniq Mirage. The mod routes the output of the eight CEM3328 filters (one per voice) to an individual output. The original modification instructions appeared in an issue of Transoniq Hacker and allows you to create an output for each voice played.

You can find the original modification instructions here:
there’s a noticeable improvement in the Mirage’s signal-to-noise ratio, even when the signals are mixed back to mono. Folks, the hiss is gone! By bypassing the final VCA and summing circuitry in the Mirage, the perpetual quiescent hiss that used to pervade my system is now at a quarter of its former strength — a noise reduction of over 6 dB in the newer Mirages and 10 dB in the older ones.
