DIGITAL FUNCTIONS
The microprocessor, in addition to storing programs, directs and controls all Level 2 functions. Some of the Level 2
functions, such as Auto Trig and Interface on-off, are basically "change-of-status" functions, and require little memory
The "recording" functions — the sequencer, the arpeggiator, and the program sequencer - require recording, not
only of status and voltage amounts, but of time values. This requires a time-measuring circuit, so the low-frequency
oscillator (LFO) is used as a clocking circuit. The resulting pitch and timing information is stored in memory, and
recalled when the appropriate "real-time" function is selected.
THE SEQUENCER
In the sequencer record mode, the microprocessor determines and stores trigger status and keyboard control voltage.
When the sequencer mode is activated, the LFO is unconditionally set at 67 Hz. This allows timing discrimination of
7.5 milliseconds (the duration of a note will never be off by more than 7.5 milliseconds).
The sequencer stores every change in trigger status and every change in keyboard voltage, whether or not they occur
simultaneously.
The following musical example:
will be stored in this manner.
