Iliis system permits adjustable resolution. Relatively coarse controls, such as the mixer level controls, may go from
minimum to maximum in one complete turn. This means that 100 values (0 to 99) are controlled by 240 status
changes, resulting in a resolution of approximately 0.41%. In other words, 12 changes of status produce a change
of 5%.
On sensitive controls, such as Osc 2 frequency, minimum to maximum can take up to 16 complete turns, yielding a
resolution of 0.025%. In this mode, 192 changes of status are needed to produce a 5% change.
The circuitry in the incrementer can reliably track over 300 status changes per second — much faster than the knob
can normally be turned, so the incrementer always responds correctly to any movement.
"Spinning" the control knob is generally not recommended; if a second control is touched while the knob is moving
freely, the setting of that control may be inadvertently altered.
A unique advantage to the *'one-knob" approach appears in editing. If a control is accessed for editing, it comes up
at the value in memory and is smoothly adjusted up or down from that point. On other programmable systems, a
control becomes active when it is physically moved. If the physical position of that control is radically different
from the value in memory, a sudden "jump** occurs. The incremental controller overcomes this limitation and ensures
smooth, subtle editing changes under all conditions.
