The Transcendental 2000 is based on the Powertran Transcendent 2000 a diy kit synthesizer from 1978. The front panel is a replica of the original except for the program manager and the page buttons on the right. Being to scale makes some of the labels a little hard to read (unless you have a screen large enough to scale it up to its original 26″ width) but the knobs are fairly standard, the switches which operate some of the most important modes of the keyboard are less so. Below are descriptions for these switches.
Transcendental 2000 is available at no cost. No registration is required.
