Manipulate and Play 'ProTracker' Modules

'ProTracker' is a popular music tracker to sequence music on a Commodore Amiga machine. This package offers the opportunity to import, export, manipulate and play 'ProTracker' module files. Even though the file format could be considered archaic, it still remains popular to this date. This package intends to contribute to this popularity and therewith keeping the legacy of 'ProTracker' and the Commodore Amiga alive.

ProTrackR

cranlogs

ProTracker is music sequencer software from the 1990s on the Commodore Amiga (see screenshot of version 2.3a on the right). This R package is designed to read, process and play ProTracker module audio files.

Installation

Get CRAN version

install.packages("ProTrackR")

Get development version from R-Universe

install.packages("ProTrackR", repos = c('https://pepijn-devries.r-universe.dev', 'https://cloud.r-project.org'))

Usage

The package comes bundled with a tiny chiptune, which can easily be played like so:

library(ProTrackR) |>
  suppressMessages()
data("mod.intro")

playMod(mod.intro, verbose = FALSE)

There are plethora of module files available on-line as well. Below you can see how you can download such a file. It also show how you can select an audio sample (number 25) from the module and calculate its power spectrum:

elekfunk <- read.module("https://api.modarchive.org/downloads.php?moduleid=41529#elektric_funk.mod")

spec <- elekfunk |>
  PTSample(25) |>
  waveform() |>
  tuneR::powspec(wintime = 0.1, steptime = 0.001)

image(log10(spec), col = hcl.colors(100, palette = "Inferno"))

While we are at it, why not play it:

playMod(elekfunk, verbose = FALSE)

Package status and alternatives

This package is no longer actively developed. It will receive minimal attention and only required updates for the latest CRAN policies. It is surpassed by the alternatives listed below.

ProTrackR2: A complete rewrite in C and C++ of the current package using the ProTracker clone by Olav Sørensen. It has similar features as the current package but has a better implementation of the tracker interpretation and is a lot faster.
openmpt: An R port of libopenmpt. It plays and renders a wide range of tracker music files, but they cannot be edited.
