General Information:
The configuration consists of two parts: program (pgm) and config (cfg).
The static configuration of the properties of the instrument is defined in a .cfg file. There is
no need to specify a config-file, as all configurable parameters have built-in default values.
They can be overridden on startup using 'property=value' pairs or by loading a specific .cfg file.
As the name /static/ implies, the properties can only be set on application start. Yet many of the
properties merely define the initial value of settings which can later be modified during
playback. The ones which can be dynamically modified are marked with an asterisk (*)
Properties are modified by sending MIDI Control-Commands (CC) to the synth. The mapping of CCs to
function can be modified by setting the "midi.controller.{upper|lower|pedal}.<CC>=<function>"
property. Function-names are equivalent to property-names. e.g.
"midi.controller.upper.22=overdrive.outputgain" assigns the overdrive-gain to MIDI-CC 22 on
MIDI-channel 1 (upper) (Note: each function can assigned only once, however MIDI-CC can be re-used
and trigger multiple function at the same time.)
The program basically defines 'shortcuts'. Loading a program is usually equivalent to sending a
series of CC. Programs are commonly used to define instruments (e.g. draw-bar settings to mimic a
flute) or provide scalepoints (e.g. reverb=64). There are a few special commands which are only
available by recalling a program (randomize settings, split-manuals, enable overdrive).
Programs are defined in a .pgm file and are fixed after starting the application. They are
activated by sending MIDI-program-change messages (also known as 'presets') MIDI-banks are
ignored. So at most 127 programs can be specified.
At startup 'default.cfg' and 'default.pgm' in $XDG_CONFIG_HOME/setBfree/ (default:
$HOME/.config/setBfree/) are are evaluated if the files exist, unless '--noconfig' or
'--noprogram' options are given. An additional config or program file can be loaded using the
'-c' and '-p' option respectively.
Example config: "/usr/share/setBfree/cfg/default.cfg"
Example program: "/usr/share/setBfree/pgm/default.pgm"
Instrument Properties:
Below is a list of available property-value pairs and their default values. The default value is
omitted "(-)" for properties which contain an array of values.
The type identifiers are: 'S': text-string, 'I': integer, 'F': float, 'D': double-precision float.
Properties marked with an asterisk (*), are available as MIDI CC functions. When used as CC, the
values 0-127 (MIDI data) is mapped to a range of values appropriate to the function. In
config-files or on the command-line you must you the type as specified e.g.
"osc.temperament=gear60 osc.wiring-crosstalk=0.2"

range: [0..12]
scanner.modulation.v2
D (6.0)
range: [0..12]
scanner.modulation.v3
D (9.0)
range: [0..12]
Parameters for 'Preamp/Overdrive Effect':
overdrive.inputgain
F* (0.3567)
This is how much the input signal is scaled as it enters the overdrive effect. The default value
is quite hot, but you can of course try it in anyway you like; range [0..1]
overdrive.outputgain
F* (0.07873)
This is how much the signal is scaled as it leaves the overdrive effect. Essentially this value
should be as high as possible without clipping (and you *will* notice when it does - Test with a
bass-chord on 88 8888 000 with percussion enabled and full swell, but do turn down the
amplifier/headphone volume first!); range [0..1]
xov.ctl_biased
F* (0.5347)
bias base; range [0..1]
xov.ctl_biased_gfb
F* (0.6214)
Global [negative] feedback control; range [0..1]
overdrive.character
F* (-)
Abstraction to set xov.ctl_biased_fb and xov.ctl_biased_fb2
xov.ctl_biased_fb
F* (0.5821)
This parameter behaves somewhat like an analogue tone control for bass mounted before the
overdrive stage. Unity is somewhere around the value 0.6, lesser values takes away bass and lowers
the volume while higher values gives more bass and more signal into the overdrive. Must be less
than 1.0.
xov.ctl_biased_fb2
F* (0.999)
The fb2 parameter has the same function as fb1 but controls the signal after the overdrive stage.
Together the two parameters are useful in that they can reduce the amount of bass going into the
overdrive and then recover it on the other side. Must be less than 1.0.
xov.ctl_sagtobias
F* (0.1880)
This parameter is part of an attempt to recreate an artefact called 'power sag'. When a power
amplifier is under heavy load the voltage drops and alters the operating parameters of the unit,
usually towards more and other kinds of distortion. The sagfb parameter controls the rate of
recovery from the sag effect when the load is lifted. Must be less than 1.0.
