11 IMPORTANTIMPORTANT
The D950 Digital Mixing System may be easily reconfigured using the optional Session Configuration Tool. Whereas the ability for reconfiguration is a great feature of the D950, it is important for an operator to fully understand the Session Configuration Tool and it’s functions. There is no safeguard functionality to prevent someone from configuring a console without e.g. the summing busses - in this case, the console may not function properly upon loading of such a configuration. Please consult the separate D950 Operating Instructions for more details on the D950 Digital Mixing System.
The D950 Session Configuration Tool is an option to the D950 Digital Mixing System. The functions, features and the appearance of the D950 Session Configuration Tool may be changed by adding or modifying the software. For this reason the operation of the Tool and it’s parts as described in this manual may be slightly different from your version.

n Windows 95 or Windows NT n Pentium processor, min. 200MHz recommended n 32 (preferably 64) MB of RAM n Display resolution 1024x768
2.12.1 Where to install?Where to install?
2.22.2 How to installHow to install
The D950 Session Configuration Tool may be installed on:
n the D950 Control PC n any other PC, provided that above requirements are met
We recommend installation on a PC different than the D950 Control PC. The programme requires a lot of processor power when it compiles. Whilst it will run without any problem in a multitasking environment with multiple programmes running at the same time, it’s performance may be considerably slowed down under such circumstances. If speed is essential, we recommend running the D950 Session Configuration Tool alone on a PC.
In some cases, the D950 Digital Mixing System may be delivered with the D950 Session Configuration Tool already installed.
Delivery of the software will usually be on a data medium (usually a 100MB ZIP disk) containing all the necessary files for installation of the D950 Session Configuration Tool in compressed or non­compressed form.
2.2.12.2.1 Installing from a compressed fileInstalling from a compressed file
If you have obtained the D950 Session Configuration Tool in compressed form (usually via e-mail), then you will start by copying the file (usually called D950cfg.EXE) into the target directory and then running the self-extracting file. This will decompress the original files and create the necessary directories for you.
10/58 D950 Session Configuration Tool V1.0 Edition: 22 July 1998
You need to extract the original files into a root directory of a drive (C, D, E, ...) on your PC. Please make sure that the „:\ADI_DSP“ directory has been placed directly under the root of your selected drive as indicated above, otherwise the Configuration Tool may not work properly.
You may now erase the files:
n D950install n i.bat n make.bat
if you wish. They would have only been needed if you had installed from a removable medium.
Now please proceed with the instructions found in chapter „Check the installation“.
2.2.22.2.2 Installing from a removable mediumInstalling from a removable medium
D950 Digital Mixing System
To install the complete D950 Session Configuration Tool from a removable medium (usually a 100MB ZIP disk), please proceed as follows.
On the removable disk drive, start the programme „D950install“. This will start a DOS batch file requesting you to select a drive letter on your target PC to install to.
We recommend to select the „C“ drive. You may select a different drive than „C“ (D, E, ...) if you wish. Please proceed by typing:
make c followed by Enter. This will copy all necessary files to the selected
drive.
Note The directory C:\D950SYSTEMDB will already exist if you are
installing on to a D950 Control PC. In this case, please use the „C“ drive for your installation.

The next step will be to create a Shortcut and then to set several options within the system.
Create a Shortcut Usually the fastest way to use a programme is to create a so-
called Shortcut on the Windows Desktop. To create a Shortcut for the D950 Session Configuration Tool, please click on the file „d950CfgTool.exe“ in the Windows Explorer, then use the right mouse button and drag the file to the desktop. Now you are ready to run the Configuration Tool for the first time.
Start the Programme Double-click on the shortcut. There will probably be an error
message „Unable to open file: xxxx“. This is because the .ini file options have not yet been set. Quit the message and the D950 Session Configuration Tool screen will appear.
Set the options Click on the menu item „Options“ and then on „Directories/Files“.
The following setup screen will appear:
12/58 D950 Session Configuration Tool V1.0 Edition: 22 July 1998

Here the names of directories and appropriate files that you’ve just copied have to be entered. The above graphic shows factory default files and paths. Since those may vary for every installation and software version, you will now need to update this entries by using appropriate file names and paths as installed on your system. The Browse button can be used to select the appropriate file, except for the following two entries:
n Temp Files Path n Config Path,
for which the appropriate paths must be entered by hand and must be followed by a backslash (\) sign. Using the example of our installation, you would need to adapt the entries as follows:
Core Function Library File Name C:\D950cfg\CoreFunc150798.lib (file form CoreFuncDDMMYY.lib)
Rtos Library C:\D950cfg\Rt070798.a (file form RtDDMMYY.a)
PE Architecture File C:\D950cfg\Ar111297.ach (file form ArDDMMYY.ach) MemNet Task of PE1 C:\D950cfg\Mn150498.exe (file form RtDDMMYY.a) MemNet Task of PE2 C:\D950cfg\Mn150498.exe (file form RtDDMMYY.a)
Temp Files Path C:\D950cfg\tmpFiles\
Log File Name C:\D950cfg\tmpFiles\LogFile.txt
Config Path C:\D950SYSTEMDB\
The above file names may be different, or have different date stamps in your case! This is normal.
Now please click „OK“ to finish the preparations and to store the edited „D950CfgTool.ini“ file automatically. This will create the

can proceed to test the whole installation. For this, you will load the included example configuration and run the compilation (known as the „Generate process“) to generate a DSP core file. This is how you will proceed:
Use the menu item „File“ and click on „Open“. A windows dialogue screen will appear and should point to the selected config path (in our example C:\D950SYSTEMDB). Select the folder „Example“ and you will see the file „Example.VMC“. Open the file.
Disregard the appearance of the screen for now, you will be able to set your workspace later on. Select the menu item „Generate“ and then „All“. This will start the process of generating the DSP and control software that is needed to run a new Session Configuration on your D950. Various messages will be displayed and after a while, a message similar to the following one should appear:
After the message „Build All finished successfully !!“ appears, click on „OK“ to finish the successful installation and test procedure.

33 INTRODUCTIONINTRODUCTION
3.13.1 Features & BenefitsFeatures & Benefits
The D950 DSP concept The concept of the D950 allows to use multiple DSP processors in
a fully scaleable and configurable way. It is possible to specify the power of the DSP core in fine steps in order to fulfil the exact need of an application. It can be said that the D950 has a scaleable DSP resource pool of computational power, which can be used in many different combinations.
Session Configuration So the concept of a „Session Configuration“ was born, which
allows to create many completely different mixers that can run on the same existing hardware. The operator is now able to choose the ideal mixer for the task he or she wants to work on.
D950 Digital Mixing System
For this, the Session Configurations can be loaded and the D950 console restarted in a matter of seconds. Each Session Configuration can contain a different console configuration based on the available DSP power. In the ever-changing studio environment, it is now possible to have a new mixer every day:
Day 1 Day 2 Day 3

Channel types All channels within the DSP core can be configured as Mono
channels or Stereo channels. The number of channels for any channel type is defined through the Session Configuration. Moreover, any channel type can be fitted with the available function blocks from the processing library. So EQ, delay or Dynamics can be fitted to Input Channels, but also to Group

D950 Digital Mixing System
DSP boards The D950 system can contain 4 board types.
Channels, Master Channels or Auxiliaries in any number and combination. Any combination of Auxiliary, Clean-feed, Multitrack Routing, audio Subgroup and Master Busses can be configured in the system.
n PE - DSP board with 6 DSP processors n PEAES - DSP board with 6 DSP processors, 8 AES/EBU inputs
(2 of which with SFC) and 8 AES/EBU outputs
n MADI I/O board with 2 MADI inputs and 2 MADI outputs n MEMNET board for communication and control
The system must contain one communication and control board called the MEMNET board.
The total number of boards in any combination can be 21 at the maximum.
System size & numbers The size and power of the system is defined by the number of
DSP processors and I/O boards installed. The total DSP power can be compared to a bucket of water (Installed DSP Capacity). The contents of the big bucket can be distributed to 4 smaller buckets (channels with fader + EQ). Alternatively, the same contents can be distributed to only 2 buckets which are larger (channels with fader+EQ+Dyn+Delay+3D-PAN...).

So, the number of available channels depends on two things:
n total installed capacity (1 - 20 DSP boards) n load required by each of the channels types and their quantity
16/58 D950 Session Configuration Tool V1.0 Edition: 22 July 1998
To complicate matters slightly, the total number of channels also depends on the number of summing busses and the number of physical I/O interfaces. To illustrate this, we can look at 3 different ways to use the same installed DSP power.

The D950 Session Configuration Tool will tell you exactly how many DSP and I/O boards you will need in order to run a certain configuration defined by the number and type of channels, the number of summing busses and the number of physical I/O interfaces. As a consequence, there is no finite maximum number of channels on the D950 - the maximum can be anywhere between 100 and 300 channels!

The D950 Digital Mixing System bases its operation on the concept of a Virtual Mixing Console (VMC). The VMC is a software structure that runs on the D950’s control PC and consists of two parts:
n console configuration (structure) n current audio settings of the console (data)
Structure The VMC describes all the parameters of a certain console
configuration such as the number of input channels, the number of multitrack busses, whether there is EQ on each channel, etc.
Data Moreover, the VMC is a real-time data container that keeps the
actual settings of a console, such as „input channel 13 EQ gain = +12dB“, „master 4 fader = -10dB“, etc. The VMC will only keep data for the channels and console parts that are defined in the structure part of the VMC. Active controls on the console such as the faders, rotary encoders, pushbuttons and the GC keyboard/trackerball control, but also the Snapshot system and the AutoTouch Automation system can write data to the VMC. Other console parts such as lamps, displays and the GC screen can read data from the VMC and display them. It can generally be said, that

almost all settings and conditions of the D950 console are a part of the VMC.
Make and edit a Configuration The D950 Session Configuration Tool can be used to make a new
configuration, or to edit an existing one. This is the first part of the process of preparing a VMC for the D950 console. That part is done off-line, even if the Configuration Tool is running on the D950’s Control PC. The result of this part is a:
n „meta“ VMC file - the definition of the console structure n a DSP core file - software that tells the DSP core what to do
Use a Configuration When we operate the D950 console, we speak of „loading a
configuration“. This means loading the „meta“ VMC file to the memory of the D950’s Control PC. This process will remove the current file from the D950 memory and load a different one. The D950 Control software will then, based on information contained in the new files, run a VMC that corresponds to the information from the „meta“ VMC file. It will also remove the current DSP core file, replacing it with a new one, thus activating a new VMC. Now the D950 is ready to work with the new Session Configuration.
There can only be one VMC that is active on the D950 console at any one time, but there can be multiple VMCs configured and stored for later use. For more information on loading a configuration and using the D950, please consult the D950 Operators Instructions.
3.33.3 The practical sideThe practical side
The purpose of the D950 Session Configuration Tool is to allow creating and modifying „meta“ VMC files and generating the DSP files from the information contained in the „meta“ VMC file. We call this process „making a Session Configuration“. There are always two files that are the result of making a Session Configuration:
n the „meta“ VMC file called MyConfig1.vmc n the DSP core file called MyConfig1.cor
The name „MyConfig1“ stands for any name selected by the user. The endings „.vmc“ and „.cor“ are obligatory and are automatically created by the Tool and do not have to be typed.
It is good practice to keep all Session Configurations in the same Windows folder, because both the D950 Session Configuration Tool and the D950 System software can be set to search in this folder automatically. The Configuration Tool will automatically create a subdirectory (folder) with the same name as the Session Configuration, so the folder structure my look similar to this:
