Edit Mode; Khz Clock Input - Alesis S4 Plus Reference Manual

If, additionally, a new Bank is selected in Mix Play Mode and any Channel's MIDI Out
parameter (Mix Edit Mode, Range Function, Page 2, Quad Knob [3]) is turned "On", a
Bank Select message (followed by the appropriate Program Change) will be
transmitted out the MIDI Out connector for each of those MIDI Channels.

Edit Mode

The Quad Knobs have two editing modes: Immediate and Pass-thru. When using the
Quad Knobs to adjust parameter values, you may prefer one mode over the other.
In Page 6 of Global Edit mode, Quad Knob [3] determines the Edit Mode of the four
Quad Knobs. When set to Immediate, parameter values jump immediately to the
Quad Knob's exact position the moment it is moved. When set to Pass-thru, the
Quad Knob must be turned beyond the parameter's current setting before it becomes
"live" and begins adjusting the parameter's value.

48 KHz Clock Input

In Page 7 of Global Edit mode, Quad Knob [1] turns the 48 kHz Clock Input on and
off. When turned off, the S4 Plus uses its own internal sample clock as a reference
for playing back the sampled sounds that make up a Program or Mix. However, if you
are recording the S4 Plus to ADAT using the Digital Out fiber optic cable and also
have a BRC Master Remote Controller, the S4 Plus must receive a 48 kHz clock
signal from the BRC in order to maintain perfect sync with the ADAT system. This
requires that you connect a BNC-to-BNC cable between the BRC's 48 kHz Clock Out
to the S4 Plus's 48 kHz Clock In. When you are ready to record onto ADAT from the
S4 Plus, be sure to turn on the 48 kHz Clock Input function. For more on connecting
the BNC-to-BNC cable, see page 25.
