REC button
In Sampling, Program, Combination, and Sequencer 
modes, pressing this button enters the initial sampling-
ready mode. The button’s LED will light up.
To continue, press the SAMPLING START/STOP 
button, as described below.
START/STOP button
In Sampling, Program, Combination, and Sequencer 
modes, pressing this when the SAMPLING REC 
button is lit will do one of three things, depending on 
the setting of the Trigger parameter (on the Sampling 
mode Recording - Audio Input page):
• If Trigger is set to Sampling START SW, sampling 
will begin immediately.
• If Trigger is set to Note On, sampling will begin as 
soon as you play a note on the keyboard.
• If Trigger is set to Threshold, sampling will begin 
as soon as the selected audio source reaches a 
preset volume level.
On the Sampling mode’s P1: Sample Edit page, 
pressing this button will play the selected sample.
This button is also used to play back WAV files from 
the disk. You can play back WAV files in the directory 
window of various Disk mode pages, in the Disk mode 
Make Audio CD page, in the Sequencer mode audio 
track editing dialog boxes, and in the Select Directory 
menu dialog box of the Program, Combination, 
Sequencer, and Sampling modes.

1. EXB-DI option
The optional EXB-DI provides word clock input and 8-
channel ADAT optical output.
WORD CLOCK IN
This allows the sample rate of the OASYS to be 
controlled by an external device. Connect this to the 
word clock output of the master clock source.
The Word Clock input requires a shielded, video-
quality cable (75-ohm or greater impedance) with BNC 
connectors. This type of cable is different from those 
commonly used in analog audio applications, but is 
readily available at professional audio and video 
dealers.
ADAT OUT
The ADAT optical output carries eight channels of 24-
bit digital audio, mirroring analog individual outputs 
1-8. You can use the Global Audio page L/R Bus Indiv. 
Assign parameter to map the main stereo outputs to 
any of these output pairs, if you like.
Connect this to any computer audio system, multitrack 
recorder, digital mixer, effects processor, or other 
digital audio device which supports the ADAT optical 
format.
2. MIDI
MIDI lets you connect OASYS to computers or other 
MIDI devices, for sending and receiving notes, 
controller gestures, sound settings, and so on. For more 
information on MIDI connections, please see “MIDI 
applications” on page 1001 of the Parameter Guide.
