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.
