Symetrix Composer v7.0 - Parameters that Cannot be Controlled Externally; Getting Started; Protocol; Control Commands

Getting Started and Control Commands
Other Parameters
Many other parameters such as compression ratios,
delay times, EQ settings and pans can also be controlled
externally. In fact, almost any DSP parameter in Composer
can be controlled. For other parameter types, as in the
above examples, sending a value of zero (0) will set the
parameter to its minimum value and sending a value of
(65535) will set it to its maximum value. Ratios, frequencies,
width/Q, and attack/release/hold times all use a logarithmic
scale. Pans and delay times use a linear scale. Quantities
expressed in dB such as gains, volumes, thresholds and
depths are linear in dB. When in doubt, experiment by
changing a value from the control application and reading it
back via RS-232 or Ethernet.
Parameters That Cannot Be Controlled
Externally
The following Composer features cannot be controlled
externally. In some cases, work arounds are suggested.
FUNCTION DESCRIPTION
1. Oscilloscope: Trigger and Auto-Range
controls
2. Parametric/British EQ: Flatten All and Octaves/Q
buttons
3. Graphic EQ: Flat button
4. Feedback Fighters: Response Preset buttons
5. Matrix: Mute All and Disconnect
All buttons (use individual
mute or disconnect buttons
instead)
6. Mixers: Link buttons (assign same
controller to all linked faders
instead)
7. SPL Computers: Calibrate button
8. Loudspeaker
Managers:
Flatten All
9. Send/Return: Meters (use meters inside
I/O blocks)
10. Delay: Default temperature button
11. Meter Bar: All meters
12. Fader Control Input: Log/linear buttons
13. String Output: All parameters
14. RS-232/485 Input: Controller number
Getting Started
Protocol
The Control Protocol is a text-based (ASCII string) protocol.
Commands are sent with simple character strings with terms
separated by spaces and completed with a carriage return
character <CR> (ASCII code decimal 13). The general form
for commands is:
<COMMAND> <PARAMETER1> <PARAMETER2> … <CR>
A white space character (space or tab) must be included
between the command and each parameter. Extra white
space characters can be sent for readability if desired. In
this document a single space will be used. If a command
is accepted, the unit will respond to each command with
an acknowledgement string whose syntax varies with each
command.
Control Commands
(CS) Controller Set
Use this command to move a controller position to a new
absolute value. The command must specify the controller
number and the new controller position. The syntax of the
command is:
CS <CONTROLLER NUMBER> <CONTROLLER
POSITION><CR>
Where <CONTROLLER NUMBER> is the decimal
controller number (1-10000) assigned in Composer, and
<CONTROLLER POSITION> is a 16-bit number in decimal
(0-65535).
If the command is accepted, the unit will respond with the
string:
ACK<CR>
If the command is interpreted but fails for any reason the unit
will respond with the string:
NAK<CR>
A typical reason for failure is that the specified controller
number does not exist.
