Studio 400 Owner's Manual
1d) Information Line
- This row of 24 characters (top line of the display) is the Information line. It
gives more detailed information about specific functions and items, and contains things like
Program names, Parameter names, and Utility or auxiliary information.
1e) Parameter Data Sections
- There are four Parameter Data sections in the display. They are imme-
diately below the Information line, and correspond with the <1> through <4> buttons on the front
panel. Each section displays the current value of the indicated Parameter. Each section also has
an arrow that shows which Parameter in the display is selected.
A CC indicator in each group tells whether the indicated Parameter is set up to be continuously
controlled ( "continuous control" includes internal LFOs, dynamic modifiers, and MIDI continuous
controller data). Directly below each section is a CHANGED indicator that lights to indicate that the
Parameter has been changed but not stored.
1f) Input Level / Clip Meters
- The bottom center of the display is occupied by the Input Level and
Clip meters. These meters show the input level of each channel, and use a peak detector action to
display the highest levels at the inputs. The Clip indicator at the end of each meter shows whether
the input signal is being clipped at the analog input section (pre-digital).
1g) Effect Routing Matrix
- The Effect Routing Matrix shows the signal flow of the currently selected
Program. This matrix includes boxes that represent each effect module along with lines that indi-
cate how those effects are connected to inputs, outputs and each other. If an effect module is
bypassed, a line appears through that module's box in the Matrix.
When in FX Edit mode, the box that represents the currently selected effect module will flash.
Likewise the Modifier module flashes the MODIFIER indicator, the Input Mode module flashes the
Input Routing indicators and the Output Mode module flashes the Output Routing indicators.
2) PROGRAM BUTTON
- Selects Program mode for Program selection. The Data Wheel is used to select
a program for loading. The Program button can also be used to toggle between the User or Factory
Program Banks. The active Program Bank is shown in the display by the Factory / User indicators (see
item 1b).
This button is also used to access the Compare mode. See pg. 14 for more information.
3) FX EDIT BUTTON
- Selects FX Edit mode for Program modification. If you continue to press this button,
you will scroll through each individual effect module, the Modifiers module and the Input/Output mod-
ules.
4) PARAMETER BUTTONS
- The Parameter buttons <1> through <4> are used to select the Parameter
or Utility item you want to edit. In Program mode, they can also be used to enter the FX Edit mode's 1st
through 4th module. To access modules 5 through 8, simply press and hold parameter buttons
<1> through <4> accordingly.
5) PREV PAGE BUTTON
- Scrolls to the previous Page in the Parameter list. Note that the Page indica-
tors change to reflect the currently selected Page number in the Parameter list.
6) STORE BUTTON
- The <STORE> button is used to store user Programs in memory for later recall.
7) NEXT PAGE BUTTON
- Scrolls to the next Page in the Parameter list. Note that the Page indicators
change to reflect the currently selected Page number in the Parameter list.
8) UTILITY
- Selects the Utility mode where global functions such as Screen Contrast, MIDI Channel,
Program Maps, SysEx Channel, SysEx Dumps, Program AutoLoad and Reset can be accessed.
9) IN LEVELS
- This button is used to access both the automatic and manual input leveling controls. For more on
setting input levels, see pg. 30.
