preset program files
Several ‘preset’ settings files (.set) accompany the converter distribution. These presets are pre-
programmed for some of the typical applications of converter, and serve as templates which can be
edited or tweaked to accommodate the specifics needed for a particular use.
Note that the file
default.set
is the work file converter uses to automatically ‘remember’ its settings
between sessions. This means that converter can be quit, and then re-run, and all the settings will be
restored from the last session – kind of like a hardware battery backup. If desired, converter can be
reset to its startup settings by loading
default.set
at any time.
The file
empty.set
can be loaded to start or return converter to commonly used default settings with
an empty midi input processor and all input sources turned off, and works somewhat like a ‘new file’
command.
The file
lastset.set
provides a safety backup of the program in use (edited or not) before a new
program is loaded, helping to ensure any programming work is not accidentally lost.
midi input processor presets
The file
m-opslib.set
contains 132 individual operations, grouped into 11 different categories (or
types) of midi input processing tasks. Each category of operations is stored in its own program slot in
the midi input processor. This preset file for the midi input processor is not intended to be used directly
‘as is’, but instead to serve as a library of ‘building blocks’ which can be copied and pasted into your
own programs.
All the operations are designed to process incoming midi messages on channel 1. Most of the
operations can be used individually; the exceptions to this are the operations in the ‘keybrd. split &
xpose’ (keyboard split and transpose) program slot – these operations are paired with partner ‘note off’
message operations, and must be used together in order to avoid stuck notes in all midi environments.
All of the operation slots in all the program slots are disabled, with the exception of the 1
st
slot titled
“PASTE OPS IN HERE”. This first slot can be used to build a custom program (group of operations)
which can then be copied and pasted to a different ‘.set’ program, or to simply try out the various
preset operations held in the other program slots. Just copy an operation from one of the other groups
and paste it in one of the operation slots in this first program.
audio input presets
There are 5 different audio to midi trigger program files, programmed for beat extraction from a variety
of styles of music. These files should serve as useful templates which can be quickly tweaked or
adjusted to work well with for a specific audio source. Some of the preset programs, such as
dltrig5.set
(programmed for a typical house track) illustrate the use of the audio to midi trigger
decay time parameter to force certain note lengths (in this case, quarter note lengths for the bass drum
etc). This technique can be useful for extracting rhythmic elements from a dense mix, where complex
rhythm extraction is not as important as accurate tracking results.
