Driver #187 Date: 2/09/98
- Enhanced analog playback/record performance. On ESS' 4-layer reference
board, playback and record SNRs are improved by 4dB, respectively.
- Turn off Reverb/Chorus as default (it was on in previous releases).
- Resolved the footstep sound missing issue at the game Jedi Knight when
the "3D Accelerator" is checked in the Display Setup.
- Add an option to turn off joystick support in DOS and Windows. This is
needed to avoid legacy resource conflict with some special joystick
like Thrustmaster's CH-F16 Combat Stick, which comes with an ACM card
with 2 joystick ports. Joystick could be disabled by following the
prcedure below:
1) In the file MAESTRO.INF, Joystick support is disabled by uncommenting
the following line:
HKR,,JoyDisable,1,01,00 ; disable joystick in DOS & Windows.
;HKR,,JoyDisable,1,01,00 ; enable joystick in DOS & WIndows.
2) Use the "setup.exe" utility to uninstall driver and reboot.
3) Driver is reinstalled and the new MAESTRO.INF file will be loaded.
4) Joystick support is disabled.

in the game "Jedi Knight" 1.0.

- Resolved clicking sound issue at the game "TigerShark".

Driver #181 Date: 1/21/98
- Support 4Meg wavetable samples. The default WT sample size is 2MB
during boot-up. The user can then dynamically change to 4MB samples
by going through Control Panel | System | Device Manager | Maestro
Wave/Wavetable Synthesis Devices | Audio Settings sequence.
NOTE: system reboot may be required when 4MB is chosen in order to
request 4MB system memory space from the OS.

API interface.

- Flexibility to customize label name in the mixer volume control
in MSTROWT.INF file. The instructions are listed below.

- Add PC Beep volume control in the mixer volume control.

The followings are the known limitations or issues.
These issues are planned to be resolved in future releases.

- There is noise in some MIDI playback when the reverb/chorus effect is
on (Bach's Bradenburg Concerto # 3.mid).

- Rebooting system with Chorus & Reverb enabled causes noise
when the system returns to Windows (intermittenly).

- For systems with SiS chipsets 5582, 5597 or 5598, legacy DOS games
in native DOS mode are not fully supported by Maestro due to the
limitation in these single-chip SiS chipsets, which don't support
Distributd DMA, PC/PCI DMA or Transparent DMA.

- The Rage3D digital joystick from ThrustMaster is not compatible
to this driver/hardware.
