Alesis BASSFIRE 60 Guide D'installation Rapide page 10

In normal operation, the Bassfire switches immediately to the program you select.
However, in some situations — especially when playing live — you may want the
ability to scroll through program numbers while remaining in the current program
setting. For example, if you've got a clean and chorusy bass sound stored in
program A3, and you want to switch next to a grungy sound stored in program C5,
you don't want to have to hear all the programs in between. In these cases, use
the Bassfire's Deferred Program Change mode.
While turning on the Bassfire, hold down either one of the Program Up or
Program Down buttons. Letters will scroll by on the display, spelling the word
"deferred."
In this mode, you can scroll through program numbers without having the
program change each time. When you arrive at a program you want to use, press
the Program Up and Program Down buttons or both pedals at the same time in
order to switch to that program.
To exit Deferred Program Change mode, turn the Bassfire off, and then turn it
back on again without holding down any buttons.
To bypass the effects section entirely, hold down both the Program Up and
Program Down buttons – or press both footswitches – for less than half a second.
The screen will read by ( ) to indicate that the effects have been bypassed.
You may now control the amplifier's volume with the volume knob. Turning any
other knob restores the effects.
Press both the Program Up and Program Down buttons – or press both
footswitches at the same time – for more than half a second to enter both Bypass
and Mute mode.
