DRIVER RE-INSTALLATION
=============================================================================*/
Make sure that all Windows copies of the INF file are deleted as follows:
- Windows 98: Delete all TerraTec INF files in C:\WINDOWS\INF\OTHER.
- Windows 95: Delete EWS88MT.INF in C:\WINDOWS\INF.
If you don't find any of these files, it's fine. Just continue with the driver update.
(The above files are a backup made by Windows during driver installation.
However, in case of a driver update Windows first searches in above folder
and therefore might use old INF files!)

/*----------------------------------------------------------------------------
EWX 24/96 under Windows 9x (VxD):
USING SONAR AND GIGASTUDIO AT THE SAME TIME
-----------------------------------------------------------------------------*/
Sonar and GigaSampler/Studio can only run together
if you are going to use the following workaround:
a) Open the registry editor:
"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\MEDIA"
Here you'll find a number of enumerated subkeys (0000,0001 etc.)
b) Click on the last enumerated subkey (e.g. 0010) to show the entries on the right side.
If the entry "DriverDesc" shows "AudioSystem EWX 24/96"
you are on the right subkey.
If not, click on the second last enumerated subkey (e.g. 0009) until you find
the desired subkey.
c) Go to the subkey "EWS HD Config"
Set the value "Disable GSIF" to 1.
d) Reboot
e) Now the GSIF driver doesn't appear any more in GigaSampler/Studio.
Select the EWX 24/96 DirectSound driver for your card instead.
If you select DirectSound driver in Sonar as well you can run both programs together.

4.02.25 Build 112
------------------------------
BUGFIX: WavePlay S/PDIF
Non-PCM Formats WAVE_FORMAT_RAW_SPORT, WAVE_FORMAT_DOLBY_AC3_SPDIF
are not checked for irrelevant parameters in WAVEFORMATEX anymore.
(BlockAlign, Channels, wBitsPerSample)
BUGFIX: EWX: The order of "WavePlay Analog A" and "B" was swapped.
This caused wrong mapping of MME to DirectSound devices.
(applies to DirectSound and GigaSampler/Studio).
BUGFIX: EWX: There was noise on the output if card was set to "External clock"
but no external clock connected.
BUGFIX: Some bugfixes regarding multiple card configurations
4.02.25 Build 110 (beta)
------------------------------
NEW: GSIF/ASIO multi-client mode
BUGFIX: MIDI-2 Out on EWS88D was not working
(this bug was accidentally introcduced after Build 98 of this driver)
4.02.24 Build 106
------------------------------
NEW: Support of multiple EWX 24/96 cards
NEW: Separate ASIO drivers for EWX 24/96 and EWS88 MT/D
NEW: EWS88 MT/D: in GigaStudio the user now has the choice between
"EWS88 MT GSIF" and "EWS88 MT DirectSound System".
BUGFIX GSIF: Added GigaSampler/GSIF version checking
GigaSampler <= 1.6 has some restrictions/bugs which require
some special workarounds in the driver.
(e.g. GigaSampler crashed if it finds more than 4 wave devices,
-> the EWS88 MT/D can only run with GigaSampler with a special workaround)
BUGFIX GSIF: When GSIF driver was active, MultiTrack MME drivers were not properly blocked.
So after another application (or Windows System Sounds) tried to playback with the MME drivers
while the GSIF driver was active, GSIF and MME drivers were in an indefinite state.
Note: This problem was encountered e.g. when trying to resample GigaSampler with WaveLab.
BUGFIX GSIF: When running GigaSampler/Studio directly after booting
the sample rate was not properly initialized.
BUGFIX ASIO: Samplerate was not restored properly
when the ASIO driver was loaded
BUGFIX ASIO: The ASIO driver initialization caused wrong settings
in the Digital Mixer Channels WavePlay 1/2
(e.g. channel 2 always muted and panned to center)
BUGFIX: "EWS88 MT/D DirectSound SystemSound-Out (Monitor)
played mono only under some circumstances.
BUGFIX: Interleaved WavePlay driver could be opened with up to 8 channel
but only played sound on some channels (e.g. 1&2),
other channels were silent
BUGFIX: When two EWS88MT/D / EWX 24/96 cards were running on the same interrupt,
MSGSRV32.DLL could cause a General Protection Fault in TTEWSSYS.DRV
at driver unload time.
BUGFIX: Gameport of another soundcard was disabled when the EWX 24/96
was installed.
4.02.22 Build 104
------------------------------
NEW: Support for EWX 24/96
NEW: DirectSound driver for the EWS88 MT/D MultiTrack part:
"EWS88 MT DirectSound WavePlay 1/2 (1)"
4.02.21 Build 102:
------------------------------
NEW: Windows waveOutSetVolume() function is now supported by all multitrack WaveOut devices
NOTE: If the card is in "Multi-Track" mode volume changes via waveOutSetVolume(), e.g.
by the volume slider within the Windows mixer, affects all wave channels!
In "Multi-Application" mode the volume can be set for each wave devices separately.
NEW: Interleaved driver now functional for up to 8 channels
NEW: Support of the TerraTec WordClock Module.
NEW: External sample rate is now always measured.
In former driver revisions the external sample rate was read from the hardware.
However, this is not always reliable if we use the ADAT input of the EWS88 D
or the new WordClock Module.
For the user, this has the effect that the external sample rate is only displayed
if the card is using external clock.
BUGFIX: Vegas hung when recording multiple channels and multi-track mode
BUGFIX: PCI enumeration only PCI bus no. 0.
This could lead to problems on a few main boards (e.g. ASUS P3C).
ASIO:
a) NEW: ASIO buffer size can now be reduced to 240 samples
which means a latency of 2 msec for 96 KHz and 5 msec for 44.1 KHz
b) ASIO driver caused a memory leak.
c) ASIO driver was blocked after using an ASIO application and could not be opened anymore.
(Error message: "Hardware is in use by other software.")
This happened especially with more than one EWS88 MT's in the system.
d) Multiple cards: Trying to change the sample rate or clock source
in the ASIO application some cause error messages sometimes.
Multiple cards:
a) NEW: Master/Slave configuration is now automatically detected by the driver.
The configuration doesn't need to be set manually anymore !!!
("Multiple Card Configuration" has become redundant.)
a) After changing from Master/Slave to Independent Mode
sometimes internal sample rates could not be changed anymore.
b) Some devices could not be cascaded (System Wave, System DirectSound, System Mixer, MIDI-1,
GSIF).
Now all devices work as they should.
System WavePlay / DirectSound
a) NEW: Sample rate conversion for the System Wave device is now done in hardware on the AC97
CoDec.
b) NEW: Driver TTEWSSYS.DRV replaces SNDENS.DRV (or TT88MT.drv in Build 98)
c) We had occasional distortions when playing other sample rates than 48 KHz
via the System DirectSound driver.
d) We had dropouts when playing DirectSound with "System WavePlay" as preferred device.
e) The "System DirectSound" driver was mapped to "WavePlay 1/2" instead of "System WavePlay"
This had the effect that even when the preferred device in Windows Multimedia settings
was set to "WavePlay 1/2" DirectSound played on the to the system output.
Windows Mixer:
a) Removed redundant Voice controls from Windows Mixer
b) Removed redundant Mono Out record source from Windows Mixer
c) CD-1 is now assigned as CD input line
d) CD-2 is now assigned as AUX input line
4.2.16 Build 98a:
------------------------------
BUGFIX: changed ASIO ID to a TerraTec specific value
4.2.16 Build 98:
------------------------------
NEW: EWS88 D support
NEW: GigaSampler GSIF support
NEW: ASIO multi-card support, new ASIO ControlPanel
NEW: DVD player support (works with PowerDVD, WinDVD etc.)
a) AC3 output via S/PDIF
b) 5.1 output via Analog Outs
NEW: SPDIF out can now be set to non-audio (-> ControlPanel)
BUGFIX: sample rates 11025, 22050, 44100 Hz wee always indicated as supported
(even if card was running on external clock)
4.2.15 Build 90:
------------------------------
BUGFIX: DC offset after playback
BUGFIX: ASIO 2.0 record caused an offset in Cubase VST
BUGFIX: ASIO 2.0 driver introduced latency
BUGFIX: Sample rate was not restored after re-boot
NEW: New API function EWS88MT_ResetCodec( )
INF file: Modifications for EWS22 & EWS88 D
CHANGE: External sample rate detection
We now start a record DMA and measure the sample rate rather than
reading it from the S/PDIF receiver.
PRO: we can now use any digital receiver(S/PDIF,ADAT etc.)
CON: the external sample rate can be only be measured while
we are in external clock mode
4.2.14 Build 80:
------------------------------
NEW: Multiple card support:
MASTER/SLAVE mode: Multiple cards are synced to one master clock
INDEPENDENT mode: Multiple cards can use their own internal clocks
-> different sample rates on different cards
NEW: Partial ASIO 2.0 support
BUGFIX: waveOutGet/SetVolume: wrong return values (ACT failed)
BUGFIX: ASIO sample rates were not updated after a clock source change
BUGFIX: ASIO clock source was not remembered in VST
BUGFIX: ASIO Record was producing pops and noises
BUGFIX: HW configuration was sometimes read wrong from EEPROM
BUGFIX: waveOutAddBuffer -> Play loops played one loop too much (ACT failed)
BUGFIX: waveInGetSamplePosition error (ACT & VST MME sync test)
BUGFIX: SampleRate was not restored after Re-Boot (always 48 KHz after bootup)
BUGFIX: Crash when shutting down with external clock enabled
