Start / Adv input the stage will pause (sustain). When the gate goes low the
stage will continue to run based on its time value.
Enable Mode – This mode is indicated when the “enbl” LED is on. This is the
opposite of the Sustain mode; the stage will pause until a gate is applied to
the Start / Adv input. At this point the stage will run based on its time value
until the gate goes low again.
Stop Mode – This mode is indicated when the “stop” LED is on. This will
cause the sequence to stop on the selected stage. A pulse to the Start / Adv
input or a press of the button will continue the sequence. Pressing the “stop”
button or applying a pulse to the “stop” input will also cause a stage to enter
this mode.
Stage Selection: Jump and loop
In the upper center, we encounter a jump and loop facility, in which the
subsequent stage is determined by some programmable logic. While in the
edit mode, use the center knob to select a loop’s last stage; then hit “set” and
use the center knob to select the loop’s first stage. The “jump to” LED’s in the
bottom of the display will be on here. Hit “set” again to activate the loop
counter and dial in the desired loop count. The loop count LED’s in the bottom
of the display will be on here. Hit “set” to return to the normal edit mode.
Stage Selection: STAGE ADDRESSING
A third scheme for stage selection is presented in the lower right section.
When in
continuous mode , the stage number is determined by the applied
control voltage. An offset control establishes the stage number for an input
voltage of zero; sensitivity to an applied control voltage is .625 volts per stage.
(A full scale excursion of 16 stages corresponds to 10 volts applied control
voltage.)
When “
strobed ” is active, the control is sampled, resulting in changes only
when a pulse is applied.
This can result in fascinating non-linear variations, especially when the input
pulse and the applied CV are independent from each other
.
Remote Enable
When active, this LED puts the 250e into contact with the preset manager,
allowing access to stored preset values.
