The Transcendental 2000 is a free vsti / standalone synth 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.
The switches are:-
Norm / NPD These stand for normal triggering where if a key is pressed and held any more notes played will not retrigger the envelopes (basically legato mode) and new pitch detect where every key strike triggers the envelopes.
KBD / OSC This is the gate signal sent to the amplifier controlled by either the keyboard or osc (LFO).
Transpose Changes the pitch of the keyboard down 2 octanes, off and up 2 octaves.
KB / Random / Off This is the filter tracking which can either be set to track the keyboard, be varied by the sample and hold or switched off.
BP / LP This is for selecting filter type bandpass or lowpass.
Single shot / Hold on Selects if the AD envelope should go straight from attack to decay or should stay at the peak of the attack until the key is released before decaying.
On / Norm / Gate This controls how the ADSR is triggered by the osc (LFO) either constantly, off or constantly while a key is pressed.
On / ADSR This controls if the signal should bypass or go through the ADSR before the output.
