ISLA Instruments S2400 User Manual

SSyynncc
Display the Sync menu by pressing Shift+Sync (the fourth key from the left in the top row).
Quickly double-clicking the Sync key toggles the clock source between internal and the last
selected external source, and closes the menu.
Sync settings control how the S2400 interacts other devices and computer software. The sync
settings, including track mapping, are saved in the global settings file (S2400.SET).
Clock Source
There can only be one clock source. The choices are Internal (meaning the S2400 controls its
own clock), MIDI DIN, USB B, USB Host, or clock in (3.5mm jack).
When clocked externally, the Run/Stop key is disabled, but Shift+Run/Stop will force the S2400
to run. Once a MIDI start message is received the external clock takes over. Pressing
Run/Stop+Rec/Edit (which normally starts recording) will arm the record function, so that when
a start message is received, recording will start with it. Pressing Shift+Run/Stop+Rec/Edit will
force the S2400 into record mode.
When externally clocked, the tempo display will show the calculated BPM with an approximately
equal to sign (ā‰ˆ). The calculated tempo is an average of 24 clock messages, and is updated every
quarter note. The number will likely fluctuate. How much it fluctuates is an indication of the
consistency of the incoming clock messages. The S2400 stays in sync with the actual clock
messages and does not use the calculated tempo; it is only displayed for reference.
Control Settings
These are the settings that determine how the S2400 is controlled over MIDI.
Control Port and Channel
This is the port and MIDI channel on which the S2400 will listen for control messages. Control
messages are machine-wide, and not track specific. They include pattern change messages
(discussed below), MIDI CC messages to set channel volume and panning, and NRPN messages
to change the parameters of any track. For details of supported CC and NRPN, see the MIDI
Control of Parameters section.
The control channel is not necessarily the same channel that the individual sample tracks listen
on. Each track has its own channel and other settings described below.
Device ID
This sets the device ID for MMC and SysEx messages.
MMC Input
Enable this option to accept MIDI Machine Control messages. MMC messages will be accepted
from any source that has transport in enabled (see below). The supported MMC messages are:
1 (Stop), 9 (Pause), 2 (Play), 3 (Deferred Play), 6 (Record Start), 7 (Record Exit), 8 (Record Pause).
