to return to Program mode and edit the program 
itself.
• OASYS’s AMS (Alternate Modulation) capability 
lets you use control changes for realtime control of 
the parameters of the programs used in a program. 
Its MIDI Sync abilities let you synchronize the LFO 
speed to changes in the tempo.
• Dmod (Dynamic Modulation) functionality lets you 
control effect parameters in realtime. You can also 
use MIDI Sync to synchronize the LFO speed or 
delay time to changes in the tempo.
Editing and operation features
• The Auto Song Setup function lets you instantly set 
up program or combination settings of Program 
mode or Combination mode as a song, so that you 
can start recording simply by pressing the 
SEQUENCER START/STOP switch.
This lets you seamlessly move from playing a 
program or combination to producing a song. 
When you come up with a phrase or an idea, this 
function lets you easily turn your inspiration into a 
song.
• Program and Combination settings can be copied to 
a song.
• Sequencer data such as a song that you create can 
be saved in OASYS’s native format, or transmitted 
as a MIDI data dump.
• A song you created can be converted into SMF 
(Standard MIDI File) data. SMF songs can also be 
loaded.
• The Play/Rec/Mute and Solo buttons let you 
instantly play/mute any desired track on the fly.
• You can rewind or fast-forward MIDI Tracks while 
listening to the sound.
Sampling features
• Multisamples you create can be played back 
together with internal programs in Sequencer 
mode. The Time Slice function of Sampling mode 
lets you divide a rhythm loop sample and create 
performance data that corresponds to the divided 
samples. In Sequencer mode you can play this 
performance data, and adjust the playback tempo 
without affecting the pitch of the rhythm loop 
sample. You can also exchange the note numbers of 
the data, or modify the timing to freely re-create 
new rhythm loops.
• The OASYS provides an In-Track Sampling 
function which lets you sample an external audio 
source while the song plays back, and will 
automatically create note data to trigger that 
sample at the appropriate point during the 
playback of the track.
Hard disk recorder section
• You can use up to 300,000 audio events (or 400,000 
MIDI events), up to 200 songs, and up to 999 
measures per song.
• Sixteen audio tracks are provided. Each track 
provides linear 16-bit PCM recording, with a 
maximum length of 80 minutes for one recorded 
take.
• Automation data (volume, pan, EQ, send 1/2) can 
be recorded for each track.
• Sixteen tracks can be played back simultaneously, 
and four tracks can be recorded simultaneously.
• The Stereo Pair function lets you control two 
adjacent tracks by adjusting just the odd-numbered 
track. This lets you simultaneously make mixer 
settings for a pair of stereo-recorded tracks.
• A broad range of internal buses can be selected as 
the recording source: Audio Inputs 1–4, S/P DIF, 
L/R, REC Bus 1–4, or Individual 1–8. Flexible 
routing even lets you insert effects into external 
audio sources and record them.
• When you realtime-record, an audio event and 
region data are created. The region data is linked 
with the WAVE data (audio data) recorded on the 
hard disk. You are free to edit this data in a variety 
of ways, such as moving the location of the audio 
event, or editing/replacing the region data or 
WAVE file.
• You can use numerous editing commands 
(including event editing) to edit the recorded audio 
events. Event editing lets you edit the time stamp 
or region data of the audio events.
• Region editing lets you edit the WAVE file 
selection, and adjust the start/end addresses of the 
WAVE file in units of a single sample.
• You can freely select a region of a WAVE file 
(mono, 48 kHz sample rate) and use it in your song. 
You can use commercially available sample data 
etc. in your song by sample-rate converting it from 
44.1 kHz into 48 kHz. WAVE files editing 
operations such as Volume Ramp and Normalize 
are also provided.
• The Time Stretch function lets you stretch or shrink 
the tempo of a phrase you recorded or a sample 
you assigned, making it match the tempo of your 
song.
• The convenient Anchor function makes it easy to 
place a phrase at the correct timing in your song.
• Auto and manual punch-in/out are provided.
• The Rehearsal function lets you practice punch-
in/punch-out recording without actually recording 
anything.
Common section
• As the MIDI clock master, you can choose either 
Internal, External or Auto, letting you synchronize 
the OASYS with other MIDI equipment.
• For each song, three-band EQ is provided on each 
MIDI track and each audio track.
• For each song, you can use twelve stereo insert 
effects, two stereo master effects, and two stereo 
total effects.
• When you’ve created songs, you can resample them 
to hard disk to create WAVE files, and then use
