Q: How Can I stabalize my Logic Audio Windows Software?
 
A:Set Virtual Memory to a fixed amount. By default Win95 dynamically allocates
hard disk space to the Virtual Memory manager. To stabilize Win95 for timing
dependent operations such MIDI Time Code (MTC), digital audio, and digital
video, try setting Virtual Memory to a fixed size. Go to Control
Panel | System | Performance | Virtual Memory. Select "Let me specify my own
virtual memory settings." You will be able to set a minimum and maximum size
for the swap file. We recommend the following guidelines when setting your
Virtual Memory:

* Set both the Minimum and Maximum amounts to the SAME size.
* Depending on available disk space, use between 60MB and 250MB for
virtual memory.

When there are multiple EIDE drives in the system, Virtual Memory should
reside on the primary hard drive.

Use a SCSI drive for Virtual Memory when possible.

Virtual should not reside on a dedicated audio or video drive.

If you have MS Plus, make sure that Low disk space notification is disabled
in the System Agent. Also make sure no other devices run while you doing
your music.

Make sure you have nothing after "Load=" or "Run=" in you Win.ini file
listed in the System Configuration Editor.

Open the Win.ini file by typing "win.ini" in the Win95 Run line, and click
"OK."

If you have MS Plus, enable (NOT disable) "show window contents while
dragging," Control Panel | Display | Plus and disable Windows animation.

Make sure you don't have any compressed drives. Go to Control Panel | System
| Performance and make sure it says "Not Installed" after Disk Compression

CD-ROM Auto Insert Notification

By default, Windows 95 is set to continuously check the CD-ROM for the
insertion of a CD so that it may automatically run the CD setup program.
This can result in audio glitches during playback and recordings because it
forces Windows 95 to continually time-slice all other running applications.
This will also interfere with the ability of a CD-R burner to write a CD by
causing the SCSI controller to error out if it checks the CD-R at the same
time a CD is being burned.

To Disable CD Auto Insert Notification:

1. Click Start on the Windows 95 Taskbar. Click Settings and choose
Control Panel.
2. Double-click the System icon.
3. Click the Device Manager tab.
4. Click the plus sign next to the CD-ROM listing to expand the list of
CD-ROM devices.
5. Select your CD-ROM and click the Properties button.
6. Click the Settings tab.
7. Uncheck the Auto Insert Notification checkbox.
8. Click OK to save your changes.
9. Follow this procedure for each CD-ROM installed on your system.

Write Caching

By default, Windows 95 is set to enable disk write file caching. This
function allows Windows 95 to write disk files in the background at some
later time, rather than at the moment you initiate a disk write procedure.
When recording soundfiles in a digital audio recorder, the data is presented
to the disk in one continual streaming operation, leaving no time for
background writing operations. When write file caching is active, Windows 95
tries to put the data in RAM first, waiting for an opportune time to write
it to disk in the background. This opportune time never comes, and Windows
95 runs out of RAM space, interrupts your digital audio recorder trying to
quickly empty its cache to disk, and potentially loses incoming data,
causing audio glitches in the recording.

To Turn Off File Write-Caching:

1. Click Start on the Windows 95 Taskbar. Click Settings and choose
Control Panel.
2. Double-click the System icon.
3. Click the Performance tab.
4. Click the File System button.
5. Click the Troubleshooting tab.
6. Check the Disable Write-Behind Caching For All Drives checkbox.
7. Click OK to save your changes.

Read Caching

By default, Windows 95 caches all disk reads to RAM. Normally read caching
can be an advantage for your digital audio recorder. Problems can occur,
however, when Windows 95 dynamically resizes the amount of space allocated
for the read-cache buffers. This can cause audio glitching during playback.

To Limit the Maximum File Read-Cache Size:

This procedure requires a good working knowledge of the Windows 95
environment. If you're not comfortable with the following steps, solicit the
help of someone well-versed in the Windows 95 platform.

1. Using Windows Explorer, navigate to your Windows folder, and
double-click the System.ini file to open it into the Notepad
application.
2. Scroll through the file looking for a section labeled [vcache].
3. Create a blank line under the [vcache] heading and type MaxFileCache =
4096. If this entry already exists, just change the size value. Make
sure the upper case and lowercase letters are maintained, otherwise
this line will not work. (This limits the maximum file cache size to
4096 Kilobytes (4 Megabytes). You can experiment with different sizes,
but the size specified should be in increments of 1024 and it is
recommended that the size not be made less than 2048.)
4. Save the file and close Notepad. Restart Windows 95 for this change to
take effect.

Double Buffer

In some cases, depending on your disk configuration, Windows 95 may create a
double buffering scheme for handling disk transfers. This can cause serious
audio glitching during record and playback.

To Disable Double Buffering:

This procedure requires a good working knowledge of the Windows 95
environment. If you're not comfortable with the following steps, solicit the
help of someone well-versed in the Windows 95 platform.

1. Using Windows Explorer, navigate to the root directory of your boot
drive.
2. Right-click on the MSDOS.SYS file and select Properties from the popup
menu.
3. Uncheck the Read Only checkbox.
4. Click OK.
5. Double-click on the MSDOS.SYS file and choose Notepad to open the file.
6.Scroll through the file looking for a section labeled [Options].
6. Create a blank line under the [Options] heading and type
DoubleBuffer=0. If this entry already exists, make sure it is =0, not
1. Make sure the upper case and lowercase letters are maintained,
otherwise this line will not work.
7. Save the file and close Notepad.
8. Right-click on the MSDOS.SYS file and select Properties from the popup
menu.
9. Check the Read Only checkbox.
10. Click OK.
11. Restart Windows 95 for changes to take effect.

Video Cards

Some video cards can interfere with the PCI bus and/or DMA operations. Many
of the newer hardware accelerated video cards will contain their own
specialized applet or settings tab in the Windows 95 Display Properties
control panel. If a checkbox exists referencing PCI bus retries or DMA bus
mastering, or something similar, try disabling this option.

Graphics Hardware Acceleration

Some video cards hardware acceleration interactions can be controlled
directly from the Control Panel in Windows 95.

To Reduce Graphics Hardware Acceleration:

1. Click Start on the Windows 95 Taskbar. Click Settings and choose
Control Panel.
2. Double-click the System icon.
3. Click the Performance tab.
4. Click the Graphics button.
5. Adjust the Hardware Acceleration slider control one notch to the left
to lower the setting.
6. Click OK to save your changes.

After restarting Windows 95, if the problem persists, try adjusting this
setting one notch lower, until the desired results are achieved. If the
lowest setting does not work, it is recommended that you reset the control
to the highest setting.

Media Control

By default, the Media Control Interface (MCI) will allocate a certain amount
of memory to buffer from 2 to 9 seconds worth of audio for the default audio
wave device. This can introduce a double buffering condition and may cause
clicks/pops and/or audio glitches when using your digital audio recorder.

To Disable the Wave Audio Device:

1. Click Start on the Windows 95 Taskbar. Click Settings and choose
Control Panel.
2. Double-click the MultiMedia icon.
3. Click the Advanced tab.
4. Click the plus sign next to the Media Control Devices listing to expand
the list.
5. Select the Wave Audio Device (Media Control) and click the Properties
button.
6. Select the Do not use this Media Control device option button. (OR
click the Settings button, and adjust the slider control all the way to
the left to the minimum setting.)
7. Click OK to save changes.

Computer Role

Windows 95 allows you to select different role types for your computer
system, and it appears that memory and disk handling may be treated
differently depending on the type selected. Sometimes selecting a different
role type may be the solution.

To Change the Computer Role Type:

1. Click Start on the Windows 95 Taskbar. Click Settings and choose
Control Panel.
2. Double-click the System icon.
3. Click the Performance tab.
4. Click the File System button.
5. Change the typical role of this machine to Mobile or Docking System.
6. Click OK to save your changes.

Background Processing

Ensure that all power management functions are disabled on the computer.
Ensure that no memory resident virus software is installed. Software of this
type intercepts all disk access and can cause audio glitches due to these
delays. Ensure that no disk compression software is enabled on any drives
regardless of whether these drives are used for audio data or not. Ensure
that no RAM doubling software is installed.

Q: I can't get LogicAudio Windows (any version) to run! I've tried many different things using Emagic's MIDI setup utility, and have switched my COM port settings (mouse on COM 1, dongle on COM 2, and modem on COM 4) to no avail! I've tried chaining the donge on COM 1 with the mouse and that doesn't work either. I'm using a MIDIQuest PC MIDI card (one in, one out) and Windows '95.
 
A: Remember on the PC configuring your system is the big problem when setting up new software/hardware so don't be alarmed when it doesn't set up easily. You can get it to work.
First off, the dongle doesn't pass through to a mouse, ignore the fact that it looks like it could. Then do this:
1. Look in Device Manager to find out what IRQs are being used in your system. You need to know what COM ports have their own IRQs, what IRQ the MIDI interface is using as well as what free IRQs you have. You MUST have each COM port using it's own IRQ. The MIDI interface also has to be on it's own IRQ. You CAN'T SHARE IRQs anywhere in your system. If you don't have enough IRQs to assign one to each COM port, then you must make room by removing some card or disabling something in your Bios like the second IDE controller (if you have just a single drive and CDRom you can put both of them on the primary IDE controller) or USB port so you have enough IRQs.
2. Assign the mouse to COM 1 (unless it's a PS/2 mouse then see number 3)
3. If the mouse is a PS/2 mouse, you can leave it alone since it is usually set to it own IRQ (12). You then can use COM 1 for the dongle and COM 2 for the modem (see number 6 if you have an external modem.
4. Make sure COM 2 is free for the dongle.
5. Setup the Internal modem to COM 3 using a different IRQ than COM 1. To do this you will need to check the manual for the correct way to do this. In general, it's done by setting jumpers on the card either by manually removing the card, then moving the jumpers to the correct position or if it's Plug and Play, open the Device Manager, open the modem resources page and manually overide the IRQ settings listed to a free one. If you an external modem see number 6.
6. If you have an external modem, you should have a PS/2 mouse. Most systems only have two COM ports on the motherboard so you can't "reuse" the IRQ for an external modem. You have to either get an PS/2 mouse, internal modem or another serial card so you have enough serial ports that can be set to individual IRQs.

Q. How do I print the Key Commands? There's no menu choice.
 
A. There are several ways do this. If you're not using 4.x Logic Audio which now includes the menu command, Print Key Commands to Clipboard so you can paste them into a word processor and then print. If using an older version of Logic Audio do the following:
1. The Key Commands are in Logic's Preference (located in C:\WINDOWS\LOGIC.PREF usually). First copy it to somewhee else. You can open the copy in a word processor or notepad, edit it so it's just the Key Commands (it'll have lots of junk in there) then print it out. If you do screw up your preferences, you can delete it because will recreate it but you will lose your setting!
2. You can do a print screen while you have the Key Command Window open
3. Use the Copy Key Command menu choice then paste it into a word processor. Then Print it.

Q. I can't use my DirectX pluggins(WavesNNP and Hyperprism). According to the manual, I should just be able to bring them up like all the other pluggins. I'm using 24bit files. I know the SoundForge/ Waves L1 only works with 16bit files. The pluggins are installed correctly and work fine with SoundForge.
 
A. You can't use plug ins that are designed for 16 bit files on files with 24 bit. The bit depth of the plug in is not big enough for 24 bit files so it can't process the data.
