1.0 New Features of the Wavestation A/D

1.1 Additional Program Bank: RAM3

The RAM3 Bank will be loaded with new, Wavestation A/D specific sounds.
It brings the total program storage of the Wavestation A/D to 200
Performances, 140 Patches, and 128 Wave Sequences (250 Performances, 175
Patches, and 160 Wave Sequences with a program Card inserted).

1.2 Additional ROM PCM Waves

The expanded PCM includes samples of a grand piano, a saxophone,
acoustic and synthetic sounds, and drums.

1.3 Analog to Digital circuitry provides two Analog Inputs

The inputs provide professional audio quality, offering a 90 dB
signal-to-noise ratio, -50, -10, and +4 dB sensitivity selections, and a
calibrated front panel VU with a peak-hold clipping indicator.

The inputs may be processed through the Wavestation A/D effects,
including several specifically designed for them (see below). The volume
of each input may be independently controlled via MIDI, allowing for
automated mixing applications. The inputs may additionally be used as if
they were PCM waveforms, so that they can be processed through amplitude
envelopes, filters, and so on - as well as the effects.

1.4 New Effects

The 8 new effects include a stereo modulatable pitch shifter, a stereo
compressor-limiter/gate with sidechaining, and 6 vocoders. The
Overdrive/Distortion-Filter-EQ 3 effects have also been enhanced to
include a modulatable output level.

For more information on the new effects, please see the accompanying
document, Korg Wavestation Effect Parameter Storage Description.

1.5 Enhanced MIDI features

Multisets and/or Multiset Effects can be changed with MIDI Program
Changes. Controllers can be re-mapped to the Joystick and Effects
controllers.

1.6 Fully Compatible with Wavestation Keyboard

The expanded features of the Wavestation A/D are simply ignored by the
keyboard version.

2.0 Implementation of RAM and PCM expansions

The Wavestation A/D has some features not included in the Wavestation
keyboard, including a third RAM bank and expanded PCM. To avoid sending
illegal values to the Wavestation keyboard, the Wavestation A/D System
Exclusive format displays a few idiosyncrasies.

2.1 RAM3 Bank

Where possible, SysEx data for RAM3 is handled by simply referencing
internal bank # 4. In some cases, however, this is not possible. These
special cases include the Multi Mode Setup, Performance Map,
Performance, and Patch dumps.

2.1.1 MIDI

For the purposes of MIDI Bank Select, RAM3 is bank #2.

2.1.2 Multi Mode Setup

The Multi Mode Setup dump is sent twice, once as a normal dump and
once as an expanded dump. The first transmission changes all
references of bank 4 (RAM3) to bank 2 (ROM); the second, with a
different header but the same data structure, allows those references to
pass through unchanged. The Wavestation keyboard ignores the expanded
dump, so that only the normal one has any effect; the Wavestation A/D
accepts both dumps, but as the expanded version is received second, it
supersedes the normal one.

The All Data dump contains the altered version of this data; the
expanded version is sent separately afterwards.

2.1.3 Performance Map

The Performance Map dump, like the Multi Mode Setup dump above, is sent
twice; once as a normal dump, and once as an expanded dump. The
first transmission changes all references of bank 4 (RAM3) to bank 2
(ROM); the second, with a different header but the same data structure,
allows those references to pass through unchanged. The Wavestation
keyboard presently ignores both dumps (Perf Maps are only communicated
as part of the All Data Dump), but future versions will recognize the
first transmission. The Wavestation A/D accepts both dumps, but as the
expanded version is received second, it supersedes the normal one.

The All Data dump contains the altered version of this data; the
expanded version is sent separately afterwards.

2.1.4 Patches in Performances

In the Performance dump, if bit 6 of Part_Mode is set to 1, then the
Patch assigned to that part is from RAM3. When this is the case, the
Bank_Num parameter, which would usually determine the bank of the Part,
is ignored.

2.1.5 Wave Sequences in Patches

In the Patch dump, RAM3 Wave Sequences are referenced by setting bits in
the Bank_Exp byte. Bits 0, 1, 2, and 3 refer to Waves A, B, C,and D,
respectively. If the bit for a particular wave is set to 1, then that
wave uses a RAM3 Wave Sequence.

2.2 Expanded PCM

Wave numbers may now exceed 396. This expanded PCM can be referenced by
either Patches or Wave Sequences. These two structures use different
methods for doing so.

2.2.1 Patches

Patches reference expanded PCM by using an extra byte, Wave_Num_Exp,
which is added to the original Wave_Num value. To reference PCM Wave
#397, then, Wave_Num would be set to 396, and Wave_Num_Exp to 1. Since
the two bytes are simply added to each other, this orderly breakdown of
the sum is not actually necessary, but it is recommended.

2.2.2 Wave Sequences

Wave Sequences use the WS_Coarse byte to access expanded PCM. When this
byte is set between -24 and 24, it functions normally to determine the
coarse tuning of the Wave Sequence step. Values between 25 and 47 are
illegal. When its value is between 48 and 96, however, the coarse tuning
is determined by subtracting 72, and expanded PCM is used for that step.
The PCM Wave number is derived by adding 365 to the value of the
WS_Wave_Num byte.

3.0 Data Transfer To and From the Wavestation Kybd

3.1 Transferring data from the Wavestation to the Wavestation A/D.

3.1.1  TRANSMIT page deleted.

The parameters on this page will be transferred by the GLOBAL system
exclusive data dump. They will be stored in the Wavestation A/D, but the
Wavestation A/D will not display them.

3.1.2 MIDI Xmit parameters removed from PERFORMANCE PART DETAIL page.

The Xmit Chan and Prog Change Xmit parameters have been removed from the
Performance Part Detail page. These will continue to be transferred by
the PERFORMANCE system exclusive data dump, or by PGM CARD. They will be
stored in the Wavestation A/D, but the Wavestation A/D will not display
them.

3.1.3  DAMPER parameters removed from FOOT PEDAL ASSIGN page.

These parameters will continue to be transferred by the GLOBAL system
exclusive data dump. The parameters will be stored in the Wavestation
A/D, but the Wavestation A/D will not display them.

3.1.4  Key offset amount parameter removed from MIDI page.

Xpose parameter added to GLOBAL page.

The Key offset amount parameter has been removed from the MIDI page, and
the Xpose parameter has been added to the GLOBAL page. Key Amount Offset
will be transferred by GLOBAL system exclusive data dump, and it will
appear as the Xpose field on the GLOBALS page of the Wavestation A/D.

3.2 Transferring data from the Wavestation A/D to the Wavestation.

3.2.1 New ANALOG INPUT ASSIGN page parameters.

These will be transferred in the extended GLOBALS system exclusive data
dump, which is ignored by the Wavestation.

3.2.2 New REMAP page parameters.

These will be transferred in the extended GLOBALS system exclusive data
dump, which is ignored by the Wavestation.

3.2.3 PERF MAP parameter added to SYSEX DATA TRANSMIT page.

This will transmit the PERF MAP system exclusive data dump, which will
be ignored by the Wavestation. The PERF MAP (with references to RAM3
changed to ROM) is also contained in the ALL dump.

3.2.4 Deleted TRANSMIT page parameters.

These will be transferred in the GLOBALS system exclusive data transfer.
Since these parameters cannot be edited on the Wavestation A/D, they can
only be changed by a GLOBALS system exclusive data transfer from a
Wavestation or a system exclusive parameter change message. All the
parameters will be set to the following default values on initial power
up of the Wavestation A/D.

Xmit Mode will be set to BASIC Channel.

Local Control will be set to ENABLE.

Program Change will be set to ENABLE.

Aftertouch will be set to ENABLE.

Pitch Bend will be set to ENABLE.

Controllers will be set to ENABLE.

3.2.5 Removed PROGRAM PART DETAIL page parameters.

These will be transferred by PERFORMANCE system exclusive data transfer,
or by PGM CARD. Since these parameters cannot be edited on the
Wavestation A/D, they can only be changed by a GLOBALS system exclusive
data transfer from a Wavestation or a system exclusive parameter change
message. All the parameters will be set to the following default values
on initial power up of the Wavestation A/D.

Xmit Chan will be set to 1.

Prog Change Xmit will be set to 1.

3.2.6 Removed FOOT PEDAL ASSIGN page DAMPER parameters.

These will be transferred in the GLOBAL system exclusive data transfer.
Since these parameters cannot be edited on the Wavestation A/D, they can
only be changed by a GLOBALS system exclusive data transfer from a
Wavestation or a system exclusive parameter change message. All the
parameters will be set to   the following default values on initial
power up the Wavestation A/D.

Damper Function will be set to SUSTAIN.

Damper Polarity will be set to (-).

3.2.7 New EFFECTS pages and parameters.

These will be transferred by PERFORMANCE or MULTISET system exclusive
data transfer, or by PGM CARD. Extended effects contained in
PERFORMANCES or MULTISETS, including the Mod Pitch Shift - Delay, the
Stereo Compressor-Limiter/Gate, and all Vocoders, will be recognized as
NO EFFECT on the Wavestation. If the parameters and effects are not
altered, however, the data will remain intact.

Please note the new Overdrive/Distortion-Filter-EQ effects, which have
been enhanced with a modulatable output level. Unlike the extended mode
effects, these can be transferred to older Wavestation keyboards, which
will simply ignore the extra parameters.

For more information on the new effects, please see the accompanying
document, Korg Wavestation Effect Parameter Storage Description.

3.2.8  Key offset amount parameter removed from MIDI page.

Xpose parameter added to GLOBAL page.

The Key offset amount parameter has been removed from the MIDI page, and
the Xpose parameter has been added to the GLOBAL page. These will be
received by GLOBAL system exclusive data transfer. The Key OffsetAmount
field on the Wavestation will be set to the value of the Xpose field on
the GLOBALS page of the Wavestation A/D.
