BASIC OPERTION OF AMT FS-2MIDI
Switching and adjustment of the device is done by using the two buttons of the
footswitch. There are several types of button pressings:
- short pressing of a button (button holding time must not exceed 1.5 seconds) is
used to quickly change the current state in main mode, or for settings change in the
setup mode;
- simultaneous short pressing of two buttons (buttons holding time must not
exceed 1.5 seconds) is used to confirm the data entered or move to the next
parameter in setup mode;
- long pressing of a button (for over 1.5 seconds) in the main mode is used to
enter command setup assigned to the button; in setting mode it is used for fast
scrolling of parameter values;
- simultaneous long pressing of both buttons (for over 1.5 seconds) in main mode
- entrance to the device modes setting.
ADJUSTABLE PARAMETERS
The device is distinguished by flexible adjustments, allowing the user to make the
most of his equipment. Basic settings are listed below (algorithms are given in the
appedix):
1. A MIDI-channel number (from 1 to 16) allows you to configure MIDI channel,
which will send and receive MIDI-messages.
2. Command type: CC (Control Change) or PC (Program Change). The user may,
at its discretion, depending on his convenience or the used MIDI-equipment change
the type of control command. This device will ignore other incoming commands.
3. Mode (OP.2c, OP.3c, OP.4c - default).
AMT FS-2MIDI OPERATIONAL MODES
OP.4c mode
is the basic mode when the device works like an ordinary 2-button
footswitch, when each pressing of the left (“1”, 1) or right (“2”, 4) button results in
FSW 1&2 OUT connector switching state change.
Working with MIDI in OP.4c mode:
CC commands, assigned to the corresponding button, with the parameter value
from 0 to 63 will break contacts in the connector, but with the parameter values from
64 to 127 – close them. When you use the footswitch the output MIDI OUT will
receive appropriate CC commands with the parameters 0 (off) and 127 (on). At the
same time the display shows the number of CC command (c.XXX, where XXX is the
number of command ) and its parameter (on or off).
PC commands will perform actions in accordance with the settings - on and off by
means of the left ("1") and right ("2") footswitch matching its PC command number.
The user needs to make sure that the custom PC command is not repeated;
otherwise it may lead to incorrect operation of the device when receiving external
MIDI-commands. When you do switching by means of the footswitch the output
connector «MIDI OUT» will receive the appropriate PC commands; the display
shows the number of the sent PC command (P. XXX, where XXX is the command
number).
OP.3c mode
is a special mode of operation introduced for proper management
of devices, which have 3 channels (for example, AMT SS-10), as well as the correct
external pedals state conversion via Control Input connector (such as AMT BC-1,
AMT SS -20 v2) into MIDI commands. The operating algorithm from the foot
switches is not different from OP.4c mode, but the sent MIDI commands uniquely
characterize the currently engaged channel (one of the three - typically, Clean, Drive
High, Drive Low).
Working with MIDI in
OP.3c
mode:
CC commands assigned to the appropriate channel of the external device (Clean,
Drive High, Drive Low) with the parameter value from 64 to 127 will set the state of
the left ("1") and right (2) switches so that the device connected to the FSW 1 & 2
OUT connector switch to the assigned channel (Clean command switches off the left
switch without changing the state of the right and Drive High or Drive Low command
sets the left switch to active state, and the right one, respectively, in active or off
state). Incoming CC commands with the parameter values from 0 to 63 are ignored.
When use the foot switch, the output connector «MIDI OUT» will receive 2
commands: one CC command with “0” parameter value corresponding to the
switched channel; the second CC command with “127” parameter value
corresponding to the switched channel. The display shows the number of the second
CC command (c.XXX, where XXX is command number) and its parameter value
(on). When you switch the right ("2"), foot switch when the left ("2") is off (Clean
mode), the transmission of commands does not occur, because actually there is no
channel change in the switching device.
PC commands assigned to the appropriate channel of the external device (Clean,
Drive High, Drive Low) will carry act in accordance with the algorithm similar to CC
commands. The user needs to check that the custom PV command is not repeated;
otherwise it may lead to incorrect operation of the device when receiving external
MIDI commands. When you use the foot switch the output connector «MIDI OUT»
will receive the appropriate PC commands and the display will show the number of
PC command (P. XXX, where XXX is command number)
OP.2c mode
- in this mode, FS-2MIDI has only 2 states: active left ("1") or right
("2") footswitch. Both switches can’t be off or active. Pressing either footswitch does
not change the device state and does not send any MIDI commands.
Working with MIDI
OP.2c
mode:
CC command assigned to the corresponding button, with the parameter value
from 64 to 127 will activate the appropriate footswitch, while the other switch
changes its state to off (according to the algorithm in this mode). Commands with a
parameter value from 0 to 63 are ignored. When you use the foot switch, the output
connector «MIDI OUT» will receive 2 commands: one CC command with the
parameter value "0", corresponding to the off state of the switch, the second CC
command with the parameter value "127", corresponding to the activated switch.
The display shows the number of the second CC command (c.XXX, where XXX is
command number) and its setting (on).
PC commands will act in accordance with the settings – switch to an active state
the left ("1") or the right ("2") footswitch. The user needs to check that the custom PC
command is not repeated; otherwise it may lead to incorrect operation of the device
when receiving external MIDI commands. When you use the foot switch the output
connector «MIDI OUT» will receive appropriate PC commands; the display
shows the number of PC command (P. XXX, where XXX is command number).
MIDI CC and PC commands for different modes are stored independently,
allowing you to work without losing any previously configured commands in
different modes.
CONTROL INPUT
CONTROL INPUT
is used to connect several devices produced by AMT and
equipped with the appropriate output connector CONTROL OUTPUT (for
example, AMT BC-1, AMT SS-20 v2, etc.). Using AMT FS-2MIDI in OP.3c
mode with 3-channel devices can accurately convert the state of the connected
device (currently active channel) into MIDI commands. After connecting an
external device it is necessary to synchronize its state with the FS-2MIDI by
switching any channel of the external device (by pressing the foot switch on the
front panel). This must be done, as FS-2MIDI monitors only the changes in the
states of switches at the CONTROL INPUT.
FACTORY SETTINGS RESTORATION
To restore the factory settings turn the device on (insert the adapter into the
mains socket) while pressing the right button. The display device will briefly
show "- - - -", indicating successful factory settings restoration.
WARNING All user settings will be permanently lost!
CONNECTION TO EXTERNAL DEVICES
WARNING! All connections must be made after the
device has been switched off!
Possible connections with external devices:
