- FM Midi Synth driver Version 1.04
- Copyright (c) 1993 by Jamie O'Connell
-
- The FM MIDI Synth driver is a replacement driver for sound
- cards that implement FM synthesis. It features an extensive
- MIDI implementation as well as support for loadable instrument
- banks and a Control Panel applet for run-time configuration of
- driver parameters. It is designed to work with as many
- different sound cards from various manufacturers as possible.
-
- Installing the FM MIDI Synth driver
-
- The first step is to unzip the FM Synth driver and related
- files (including the one you are reading) to either a
- diskette, or a directory on your hard drive. The driver
- will be installed from this location (make note of the disk
- and/or directory name).
-
- More hardware configuration parameters are provided than are
- available for most drivers. In order to optimally configure
- the FM Synth driver, it is important to have prior knowledge
- of the hardware configuration of your sound card.
-
- The FM Synth driver is installed via the Windows Control
- Panel Drivers applet. The following steps are performed
- when installing a new driver:
-
- 1) Remove any existing FM driver. It is recommended that
- any existing FM driver be removed before installation is
- attempted. While it is possible to have more than one FM
- driver installed, it is essential that only one be in use
- at a given time. Note: Only the FM driver should need
- removal, not the Wave, MIDI or Aux. driver. To remove a
- driver, open the Drivers applet, select the FM driver to
- remove (this could be the Adlib driver, the SB Pro 2 FM
- Synth, the Voyetra OPL3 FM driver, or some other name).
- Press the remove button and answer OK to the dialog box
- which warns that the driver may be needed by the system.
-
- 2) Restart Windows. After removing a driver, you must
- restart or exit Windows before adding the FM Synth driver.
- This is because the driver has only been removed from the
- SYSTEM.INI file, and is still present in memory -- a new
- driver can not be loaded until the current one is remove
- from memory.
-
- 3) Install the FM Synth driver. Open the Drivers applet
- from the Control Panel and press the Add button. Select
- Unlisted or Updated Driver from the list and press the OK
- button. Type the full directory name, or floppy drive (ex:
- B:\ or C:\NEWDRV or wherever you put it) of the location
- where the driver resides into the dialog box and press OK.
- A dialog box containing the name: Jamie O'Connell - FM Synth
- MIDI Driver will be presented. Ensure that it selected and
- press OK.
-
- Note: If you receive a message stating that the CTL3DV2.DLL
- driver is already on the system, or a message stating that
- the driver is in use (when you know you've removed it and
- restarted), don't despair! The message simply refers to the
- fact that some other application is currently using the
- CTL3DV2.DLL file. The driver has most likely been
- successfully installed: don't restart yet. Repeat the 3rd
- installation step, but this time select Current, when asked
- whether to use a New or Current driver.
-
- Next the FM Synth hardware configuration dialog is
- displayed. This dialog only needs to be filled out once,
- but the selections are critical to proper driver operation
- (the dialog can be opened again later, if required, by
- opening Drivers, selecting the FM MIDI Synth and pressing
- the Setup button).
-
- Note: when re-installing a newer version of the FM Synth
- driver, you must first remove the older version as detailed
- above.
-
- Configuration
-
- The FM Synth Setup dialog contains two sections: I/O Port
- Address and sound card FM chip type.
-
- I/O Port Address
-
- The I/O Port Address is the physical port of the FM sound
- chip. In some sound cards this may be different from the
- cards base address. For instance, the original Sound
- Blaster 1.5 has a base port address of 220 hex, but the FM
- chips are located at port address 228 hex. You would choose
- port 228 for this card.
-
- FM Chip Type
-
- The FM chip type depends on which card you posses. The
- earliest Adlib and Sound Blaster FM Cards contained a single
- Yamaha OPL2 sound chip. The first version of the Sound
- Blaster Pro added a second OPL2 chip. Early Media Vision
- Pro Audio Spectrum cards also have the 2 OPL2 configuration.
- Newer sound cards, including the SB Pro 2, and the MV PAS 16
- use a single Yamaha OPL3 chip. The OPL3 contains the
- equivalent of 2 OPL2 chips plus some other features such as
- 4 Operator support. Almost all sound cards implement Adlib
- compatibility: Port: 388 hex, 1 OPL2 chip, though choosing
- this setting may reduce the capabilities of the driver (The
- Adlib is a mono only card capable of 9 melodic, and 5
- percussive simultaneous voices).
-
- It should be noted that the FM Synth driver does not require
- knowledge of either the DMA or IRQ for the sound card, as
- these are only used for the digital sound, and MIDI portions
- of the cards. Following is a table of settings for some
- common sound cards with factory setup configurations. If
- your card is not listed, or has been changed from the
- factory setup, consult the user manual issued with the card:
-
- Name I/O Port Chip
- (hex) Type
- --------------------------------------
- Adlib FM Card 388 1 OPL2
- Sound Blaster 1.5 228 1 OPL2
- Sound Blaster Pro 220 2 OPL2
- (original)
- Sound Blaster Pro 2 220 1 OPL3
- MV PAS (original) 388 2 OPL2
- MV Pro Audio 388 1 OPL3
- Spectrum 16
-
- If the Port address for your card is not listed in the
- dialog box, select Other and type the hexadecimal port
- address into the edit field. Next choose the chip type and
- press the OK button. If an FM chip is detected, the dialog
- box will close, and a restart warning is issued. Go ahead
- and restart Windows once again. If an FM chip is not
- detected, a message stating that the hardware settings on
- the card do not match the selected driver I/O Port address
- is issued. In this case, you must change the I/O Port
- Address setting -- as stated before, Port 388 can almost
- always be specified.
-
- After restarting Windows, a Control Panel applet, FM Synth,
- will be available for run-time configuration. A Windows
- help file is attached to a button on the applet.
-
- Programming the driver
-
- See the SYSEX.TXT file for System Exclusive information.
- In addition there is a limited programming interface.
- See the STMB.H or STMB.PAS files for more information.
-
- Changes
-
- Version 1.01 repairs a bug caused when the driver was handed
- illegal MIDI data. In addition, the default is to now NOT
- switch percussion mode off and on for channel 10, upon
- receipt of program change 127 or 126. If you would like
- this behavior, add to the [Mode] section of the FMSYNTH.INI
- (in the Windows directory) the followinfg switch switch:
-
- [Mode]
- OldPercSwitch=1
-
- Also see the CHGFMSYN.TXT file for additional information.
-
- Getting Help
-
- If you experience problems when using the driver, or have suggestions
- about the program, documentation, etc., you can contact me directly or
- post messages here in the Sound Card section of Compuserve's Sight &
- Sound or MIDI forums. I'll be monitoring the sections, and keeping the
- latest driver versions there.
