Defining the sweep contents
A “sweep” might be a less intuitive concept in the TinyBox setup architecture. It’s a way to describe
the functionality of an expression pedal. You first list the different required functionalities (volume,
wah, expression, … ) as the possible “sweeps” in your setup. In the sweep definition (see syntax below)
you specify the MIDI commands necessary for each of those functions. Once you have specified this, a
simple command can link any of the sweeps to one of the two FCB1010 expression pedals. Such a pedal
assignment command (see chapter 5.1) can be added to any preset or effect. This allows for a very
flexible use of the expression pedals: they can serve a different function depending on the current
context.
The syntax for defining sweep contents will look familiar by now :
SWEEP whammy = SendMidi DX7 PitchBend 0-127
SWEEP volume =
{
SendMidi Profiler CtrlChange 7 0-127 SlowRising
SendMidi Strymon CtrlChange 7 40-100 SlowRising
}
The sweep definition can only contain “continuous control commands”: these are the MIDI commands
used for continuous parameter adjustment: “CtrlChange”, “PitchBend” or “ChannelPressure”.
By default the sweep curve when moving an expression pedal will be linear. However you can also
specify that a sweep needs to be “SlowRising” or “FastRising”. An analog volume pedal for instance
typically uses a “log taper” (sometimes called an “audio taper”). This taper increases the volume more
slowly at the beginning of the pedal movement, and more steeply at the end. You can mimic this
behavior with your digital FCB1010 expression pedal by specifying a “SlowRising” behavior for this
sweep:
