Using the OASYS PCI

Working With Files

File Types
OASYS PCI uses seven different types of files: Multis, Programs, Patches, Effects,
Samples, Multisamples, and Scales.
Multis contain an entire setup for the OASYS PCI, including all Mixer, Send Bus,
and Output Bus settings, links to all selected Programs and Effects, and all Patch
and Effects Control Panel settings. (Control Panel settings can also be stored in
Programs, if desired.) Multis have the file suffix "oam."
Programs are the basic sounds of the OASYS PCI, and must be placed on a Multi
Channel to be played. They play one or two Patches, which can be layered or split
by key and velocity ranges. They also have up to four Insert Effects, which appear
in the Mixer Channel. Programs store all Control Panel settings for their Patches
and Effects. Programs have the file suffix "oap."
Patches are the basic units of sound creation on the OASYS PCI. They must be
placed in a Program in order to be played. Each Patch contains its own synthesis
algorithm, which may be quite different from one Patch to another. Patches have
the file suffix "oas."
Effects are used to modify the sound of Patches, Audio Inputs, or Streams. They
can be used as insert effects in the Mixer Channels and Output Busses, or as send
effects via the Send Busses. Each Effect contains its own audio processing
algorithm, which may be quite different from one Effect to another. Effects have the
file suffix "oae."
Samples are audio files, which can be placed in a Multisample (see below) and then
played back by sample-based OASYS PCI Patches. OASYS PCI recognizes mono
and stereo 16-bit and 24-bit samples in a number of different formats, including
AIFF, WAV, and Korg's proprietary .kes (mono) and .k2s (stereo) formats.
Additionally, Sound Designer II samples are supported on MacOS only.
Multisamples are collections of one or more Samples assigned to ranges across the
keyboard. Each key range has offsets for common parameters, such as volume, pan,
filter cutoff, decay, and so on, which can be used to adjust Patch parameters
individually for each Sample. Mono Multisamples have the file suffix "kem," and
stereo Multisamples have the suffix "k2m."
Scales control how MIDI note numbers affect the pitch of a sound. Any MIDI note
number can be set to create the pitch of any other note, with both coarse and fine
tuning. Each Patch in a Program can be set to use a different Scale, if desired. Scales
are simply text files, so they're easy to create and edit. See "Scales," on page 137 for
more information.
