Description

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

ProTracker 2.3a

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)

Developmental status

It has been a decade since the initial release of this package. Since it’s release a lot has changed in R and in my skill set. I still have plans for this package, but this requires drastic changes. Therefore, I will only apply minimal maintenance to this package. Meanwhile I will work on a complete overhaul which will be released in due time as a new package. This new package will:

  • have the same or similar features as the current package.
  • will implement modern R features and try to adhere to tidyverse principles.
  • implement rendering procedures in C++ giving the package a speed boost.

But until then, please enjoy the current package as is.
