Functions
Functions are certain actions or commands that can be carried out in the various modes. Depending on the mode,
only certain functions are available, as listed below.
• Manual mode: Store function, effect on/off function
• Memory mode: Store function, effect on/off function, MIDI channel setting function
• Recall mode: Store function (as part of the recall operation)
■ Store function
This function serves to store effect settings adjusted in manual mode or memory mode into memory.
Settings stored in this way can be activated instantly in memory mode.
If the store function has been completed in manual mode, the 1204 automatically switches to memory mode.
The store function as used in the recall mode differs slightly from the store function used in other modes.
■ Effect on/off function
The 1204 allows the user to quickly turn off all effects, so that only the original (DRY) sound is output. Effect
on/off switching is normally performed using the EFFECT key on the front panel of the 1204, but in memory mode
it can also be controlled by external MIDI equipment. For details, please refer to page 22.
Note: For reasons of simplicity, this instruction manual uses the expression "original" or "DRY" sound for the
output signal that is supplied by the 1204 when the effects are switched off. However, since the 1204
converts the analog input signal into digital form for internal processing and reconverts it to analog form for
output, the output signal is not exactly the same as the input signal. Audibly, there will be practically no
difference, but a very slight time delay is introduced by the processing circuits. When using the 1204 in the
send/return loop of a mixer, the DRY output should be turned fully down, to prevent interference (flanging)
between the actual original sound and the output of the 1204.
■ MIDI channel setting function
This function can be used only in the memory mode.
The function serves to select the channels in which the 1204 receives control signals sent from external MIDI
equipment.
The MIDI (Musical Instrument Digital Interface) standard allows electronic instruments and other devices to
mutually control each other. The MIDI standard includes 16 control signal channels which are numbered 1 through
16. By assigning these channels in different ways, it is possible for example for one master MIDI device to control
two slave MIDI devices independently.
The MIDI channel setting function allows the user to set the 1204 to receive all MIDI control channels, to activate
only certain channels, or to entirely deactivate MIDI control. The selected setting is retained also when the 1204 is
turned off. Normally, it is recommended to set all MIDI channels to ON.
