- This code is a Windows MME driver for the M-Audio Capture and Playback Adapter.
- The support for the IBM M-ACPA consists of nine files.
-
- FILE NAME FILE SIZE
-
- ACPA.DRV 34832
- AUDIO.DLL 97294
- README. 7010
- ACPADD.SYS 44513
- IBMAUDS.DSP 14957
- IBMPCMP.DSP 7277
- IBMPCMR.DSP 7277
- OEMSETUP.INF 2005
- MIDIMAP.CFG 29249
-
- Copy all nine of the files to the root of a new diskette. Use the new
- diskette to install the driver using the Windows Installation Applet. To
- install the driver using the Windows control panel driver installation
- applet follow the instructions below.
-
-
- To install a new driver
-
- 1. Edit the "SYSTEM.INI" windows file. Under the driver section,
- remove any "wave=xxxx.xxx" entry.
-
- 2. If the ACPA.DRV or AUDIO.DLL exist in your \system
- sub-directory or Windows path, delete them.
-
- 3. Start Windows and place your diskette in A:.
-
- 4. Select the Control Panel icon from the Main Group.
-
- 5. Choose the Drivers icon from the Control Panel.
-
- The "Installed Drivers dialog box" will appear, displaying a
- list of the installed drivers.
-
- 6. Click on the Add button.
-
- The "Add Driver dialog box" will appear, listing the
- drivers available on your hard disk.
-
- 7. Click on the Add Unknown button.
-
- The Add Unknown Driver dialog box appears, prompting you to
- choose the drive and filename for the driver you want to
- install. Enter "A:\". Then click on OK.
-
- IBM M-Audio Sound Driver will be added to the Add Drivers
- dialog box.
-
- 8. Select IBM M-Audio sound driver. Click on OK.
-
- 9. Wave, MIDI, and Aux entries for IBM M-Audio sound driver will be
- added to the Installed Drivers Dialog Box.
-
- 10. Click on the Setup button.
-
- 11. Select the appropriate input and output source from the
- dialog box.
-
- 12. Choose OK.
-
- 13. Choose restart Windows for the new settings to take
- effect.
-
- Note:
- There is a potential problem that exist with multiple applications
- trying to use the M-AUDIO hardware at the same time from different
- operating system enviroments. An example of this would be executing
- a Windows Multi-Media application using audio and switching to the
- DOS box and running a DOS application that uses the M-AUDIO hardware.
- The file ACPADD.SYS is used by the driver to serialize the use of the
- hardware. This will prevent contention for the hardware with any other
- application that uses the ACPADD.SYS or a derrivative of it. In order
- for this scheme to work a modification must be made to the SYSTEM.INI.
- In the SYSTEM.INI under the [drivers] section there should be three
- entries associated with acpa. The three entries should appear as
- follows:
-
- wave=acpa.drv
- midi=acpa.drv
- aux=acpa.drv
-
- The above three lines must be modified to the following:
-
- wave=acpa.drv wave
- midi=acpa.drv midi
- aux=acpa.drv aux
-
-
- MIDI Configuration:
-
- MME uses the MIDI Mapper to support MIDI. In order for the M-AUDIO
- driver to support MIDI it must be configured to work with the Mapper.
- All modifications are saved in the file midimap.cfg Because MME does
- not provide a means of merging data into this file the setup must be
- performed manually. A midimap.cfg file is provided along with the
- driver. This file can be copied over your existing file. There is no
- gaurentee that everything else will be the same in the two files. It is
- suggested that the manual steps be followed to insure no data loss. If
- however, you do not want to spend the time it is suggested that you
- save your old midimap.cfg file and copy the one provided with the
- driver.
-
- To configure the Mapper follow the instructions below:
-
-
- 1. Start Windows.
-
- 2. Perform the driver installation instructions above.
-
- 3. Select the Control Panel icon from the Main Group.
-
- 4. Choose the MIDI Mapper icon from the Control Panel.
-
- Depending on the hardware configuration of your system, You
- might get a dialog box displayed at this point warning that the
- current MIDI setup references a MIDI device which is not
- installed in your system. The warning will ask if you want to
- continue. Click YES.
-
- 5. Under Show, select Setups and Click on New.
-
- 6. In the New MIDI Setup dialog box type a name your want to call
- this MIDI mapping (M-AUDIO) in the name field followed by a
- description if desired (IBM M-AUDIO mapping). Click OK.
-
- 7. A new dialog box labeled MIDI Setup: followed by the name
- you selected in the previous step will be displayed. Under the
- column labled 'Port Name' place the mouse cursor on row
- thirteen. Press the right mouse button. This action will
- select that row and display an down arrow. Click on the down
- arrow to display the options that can be selected for the chosen
- port. Select the options 'IBM ACPA MIDI SYNTH', repeat this
- process for ports fourteen through sixteen. Click OK when
- finished.
-
- 8. From the Show section of the dialog box select Patchmaps and
- Click on New.
-
- 9. In the New MIDI Patchmap dialog box type a name your want to
- call this MIDI patchmap in the name field (M-AUDIO) followed
- by a description if desired (IBM M-AUDIO mapping). Click OK.
-
-
- 10. The voicing for the M-AUDIO synthesizer has been mapped to
- correspond with that of General Midi mapping. All of the
- voices should have a one to one mapping ie voice 16 of the
- mapper should map to voice 16 of the synthesizer. This is the
- default mapping so nothing else has to be done.
-
- 11. These are the only modifications that are needed for the
- Synth module. Make sure that the name you selected is
- displayed in the name field. If it is not Click on the down
- arrow in the name field and select your name. Click on OK
- to switch to your new Synth module.

- PERFORMANCE
-
- The ability to use all of the M-Audio modes will depend on several factors
- relating to your host machine and environment. These items include host
- system speed, channel speed, host processor disk performance(speed and
- fragmentation) and memory availability. Performance problems can be
- identified by the following behavior:
-
- 1) Sections of good audio intermixed with noise.
-
- 2) Sections of good audio intermixed with silence.
-
-
- If you are experiencing problems attempt to alleviate the problem using
- the following suggestions:
-
- Record
-
- 1) Make sure that verify is off on disk writes.
-
- 2) Use a VDISK as the file destination of a recording.
-
- 3) Defragment the hard disk before recording.
-
- 4) Record as a foreground activity.
-
- Playback
-
-
- 1) Move the audio file to a VDISK and play it from that location.
-
- If the above suggestions do not solve the problem a higher performance system
- will be required to use the faster data rate modes. In slower performance
- systems lower data rate modes must be used for proper operation.
