Description Of Algorithms - Art SGX-2000 User Manual

When you are in Preset or Edit Mode, the LCD will inform you of either
Performance MIDI or FX ON/OFF information being received and what is being
changed.
There is also a means to monitor MIDI information being sent to the SGX 2000.
While you are in the PM Mode you can select the MIDI Monitor utility and verify
MIDI data being sent to the device. Refer to the MIDI DataMONITOR section for
additional information.
A table of MIDI controllers can be found in Appendix E, Tables and Charts.
Presets in the SGX 2000 are set up to be controlled by Performance MIDI via the
ART X-15 ULTRAFOOT. See the section "Operating the Multiverb SGX 2000 with the X-
15 ULTRAFOOT" further on in this manual for more information. Don't let MIDI
scare you. Using Performance MIDI in an ART device is easy. In most cases
(especially with an X-15) you virtually plug in and play. But, if you want to
program, we've made that easy too.
Modification to select the specific values and ranges you want the parameter to
cover is done by normal editing. The number displayed in the upper left corner
represents the MIDI Controller you are working with. Performance MIDI has four
levels of programming information associated with it broken up into 4 screens.
The first screen displays the information to define what parameter the assigned
MIDI controller will control.
The second screen shows which MIDI controller is being used. The LCD will display
the MIDI control number and its description (i.e. MC 4 FOOT CTLR). Incidentally,
the default value is MC 4 which happens to be the Left Foot Controller on the X-
15. The MIDI DataMONITOR may be selected for use in this screen to display MIDI
data being sent.
The third screen displays the LOW value (minimum value) of the parameter's range.
The fourth screen displays the HIGH value (maximum value) of the parameter's
range. High and Low values refer to MIDI controller values. These parameters may
be "swapped" to make the value change in a reverse or opposite direction.
While you are in the first screen you may also view MIDI data. Change the value
until the bottom of the screen displays MIDI DataMONITOR. (turn the Encoder
counterclockwise) You are allowed to change between MIDI controllers on the
device you are sending MIDI data from (keyboards, X-15, etc.) and view the
corresponding data in this screen. The top half of the display will show the
numerical value of the MIDI data being received by the SGX 2000. Displayed in the
bottom half is the actual MIDI controller being used. Use the Value Up or Down
key to change the MIDI controller. When you change the controller, its MIDI data
will be displayed in the top half of the LCD.

DESCRIPTION OF ALGORITHMS

The SGX 2000 offers over seventy effects selections for you to choose from. Each
effect may have several types to select for specifically narrowing down the
particular sound you are looking for. The algorithms are listed in seven
categories in the manual. These are: Analog Effects, Signal Frequency Shaping,
Swept or Modulated Effect, Natural Reverberation, Gated Reverberation, Delay, and
Utility/Level.
