NOTE: This keyboard is made to order! Buyers can expect their order to ship within around one week of purchase. Thank you!

The Haunted PSS-140 is our custom-modified version of Yamaha‘s home FM keyboard from 1988.

Modifications include:

  • 8 point data patch-bay and 8 data interrupt switches that allow the user to methodically edit the PSS-140’s stock sounds & features by injecting arbitrary bits into the CPU & sound chip
  • quick reset button
  • improved 1/4” line out

*See the linked Youtube video above for a demo of these mods in action*

All of the original PSS-140 features are intact and unaffected when the patch bay & data bend switches are turned off. When turned on, they can be used to reproducibly modify its 100 stock voices in thousands of unique ways. The patch bay also effects the rhythm section in the form of stutters, drum fills, octave changes, melody detuning, and lots more.

It’s authentic vintage sound and arsenal of custom effects work together to create a sound you won’t find anywhere else; a blend of classic 80s tones and chiptune-esque digital distortions that make it the perfect instrument for vaporwave, hyperpop, and synth-pop.

Comes with the keyboard, 2 patch cables, and a short manual for operating the data switches & patch bay.
