921 Oscillator 921A Oscillator Driver 921B Oscillator |
1 4 12 |
The 921B's were each modified with the addition of an LFO switch that allowed you to break the connection from the 921A while dropping the frequency a couple octaves and increasing the range of the front panel Range control. Also, the "CV In" jack was modified for exponential rather than linear response. |

Each Envelope Generator had both V & S-Trig Inputs with LED indicator. Also, a Regen switch was added to each that routed the output to the V-Trig Input, allowing it to be used as an LFO, with the waveshape and frequency determined by the Attack and Decay times. |

The scale programmer was modified to allow macro as well as micro-tonal scale tuning, and the panels were redesigned to run the length of the cabinet (bottom row). The Switchboard to the left of the keyboards was just a big mixer, an input for each key of the lower keyboard, and one output. |
