Create Minilogue XD .scl File

Source: R/output_functions.R
minilogue_xd_scl_file.Rd

Writes a Scala .scl file for the Korg Minilogue XD

Usage

minilogue_xd_scl_file(
  keyboard_map,
  output_file_path,
  scale_description = "'https://algocompsynth.github.io/eikosany/' made this!"
)

Arguments

keyboard_map

a keyboard map created by keyboard_map

output_file_path

path to a file for which you have write permission

scale_description

tell the user what scale this is. The default includes a link to the pkgdown website for this package.

Value

a character vector containing the data written to the file. Each element of the vector is a line of ASCII text.

Details

The Korg Minilogue XD can be microtuned in two ways:

  • 1. A user octave: all octaves of the synthesizer are retuned using offsets in cents from 12EDO notes. For scales with 12 or fewer notes, such as a hexany or dekany, this will work, and you can use the offset_matrix function to compute the settings required. This is easy to do either on the synthesizer or using the Korg minilogue XD Sound Librarian.

  • 2. A user scale: this microtunes the whole MIDI keyboard from MIDI note numbers zero through 127. You will need to use this method for an eikosany, since it has 20 notes.

The standard process to microtune a user scale is to use the Korg minilogue xd Sound Librarian. You load a Scala .scl file or an .scl and .kbm file for the scale into the librarian and upload to the synthesizer. The .scl files from minilogue_xd_scl_file are designed to remap the entire keyboard with just a .scl file. See the vignette "Tuning the Korg Minilogue XD to the 1-3-5-7-9-11 Eikosany" for details.

Examples

if (FALSE) {
# `cps_scale_table` returns the 1-3-5-7-9-11 Eikosany by default
eikosany_map <- keyboard_map(cps_scale_table())
file_contents <- minilogue_xd_scl_file(
  eikosany_map,
  "~/minilogue-xd-eikosany.scl",
   "Eikosany 1-3-5-7-9-11"
)
}
