4. PLAY MODE
The section which follows will describe the PLAY MODE: we will discuss the way in which the
GM 400 will be used while the patches are being played. The next section, entitled EDIT
MODE, will describe the procedure for programming a patch. This section will refer almost
only to the main video page.
4.1 KEYS AND CONTROLS
Cursor.
Four green illuminated keys to the right of the display and on the left of the Value Encoder are
called CURSOR keys. They allow the user to move the flashing cursor, used to select a
parameter to be modified, around the display. The top key moves the cursor upwards, the key
on the right moves the cursor to the right, and so on.
Value.
Once the parameter to be modified has been selected, the Value Encoder allows the user to
vary its value. Turn the knob clockwise to increase the selected value or anti-clockwise to
decrease. The encoder works dynamically; in other words, the speed at which it is turned
establishes the speed at which the selected value is varied.
General bypass.
To listen to the signal exactly as it reaches the INPUT socket, the user can completely bypass
the algorithms which process the signal by pressing the BYPASS key with the main menu
page on the screen. To confirm this operation, the light in the BYPASS key will begin to flash.
Press the BYPASS key again (the light remains constantly on) to return to the initial
conditions. This type of bypass is referred to as a GENERAL BYPASS to distinguish it from
the LOCAL BYPASS to be described in the EDIT MODE section.
Phones output.
This socket allows the user to listen to the results of the GM 400 signal processing on
headphones. Once the jack has been connected to the PHONES OUTPUT socket on the left
of the panel, optimize the playback volume as preferred using the PHONES LEVEL trimmer
immediately above the PHONES OUTPUT socket.
