Project Description

RnsUtils is Renoise related library and companion utility. It is meant for developers aiming to use generate renoise file or renoise users wanting to convert SoundFont 2 or SFZ to renoise instruments, reencode instruments to .flac or .ogg, manipulate tags and comments in instruments or organise a xrni library based on those tags.

Installation

RnsUtils is installable from PyPI with a single pip command:

pip install rnsutils

Alternatively, RnsUtils can be run directly from sources after a git pull:

git clone https://gitlab.com/zeograd/rnsutils.git
cd rnsutils && python setup.py install

sf2toxrni

sf2toxrni is a command line utility which convert SoundFont 2 instruments into renoise instruments (.xrni). It parses a SoundFont 2 file instrument list and generate one .xnri file for each instrument using as much information from the SoundFont 2 instrument properties (generators) as possible. All read properties will be injected in a template renoise instrument.

usage: sf2toxrni [-h] [-d] [-e {none,flac,ogg}] [-f] [-q] [-u] [--no-unused]
                 [-o OUTPUT_DIR] [-t TEMPLATE]
                 sf2_filename [sf2_filename ...]

GPL v3+ 2016 Olivier Jolly

positional arguments:
  sf2_filename          input file in SoundFont2 format

optional arguments:
  -h, --help            show this help message and exit
  -d, --debug           debug parsing [default: False]
  -e {none,flac,ogg}, --encode {none,flac,ogg}
                        encode samples into given format [default: flac]

  --no-unused
  -o OUTPUT_DIR, --ouput-dir OUTPUT_DIR
                        output directory [default: current directory]
  -t TEMPLATE           template filename [default: empty-31.xrni]

Convert sf2 file into renoise instrument

Use the -o option to specify a destination directory and –no-unused if you don’t want to see the list of generators which are present in the SoundFont 2 file but were not used in generating the .xnri.

-t allows to change the template .xnri, one is provided by default and works with renoise 3.1 at least. If you want different default settings or generate instruments for a different version, you can provide a template of your own and specify its filename. If the filename is not found on the filesystem, it will be looked up in the default data patch for the python package. If you want to provide your own template, it must follow the recommendations of the following section.

template

A template .xnri file will be used to have Soundfont 2 properties injected to produce a final, customized .xnri file. It must contains at least one sample. The first sample will be used as template for all samples, others will be discarded. The first sample must have an ADHSR modulation on volume and the filter set to a Low pass filter. SoundFont 2 reverb and chorus effects will be mapped respectively on macro 1 and macro 2, so you may want to map those macros on input of DSP chains to control the dry/wet amount of those effects. You may use macro 3 and up to your liking.

compliance and limitations

The set of features found in a SoundFont 2 and .xnri doesn’t fully overlap, hence this converter won’t produce a bit wise exact instrument. First, SoundFont 2 files contains presets, which are mapped to one or more instruments. Those presets might alter how the instruments sound, but it’s a bad practice and usually only map keys range to instruments. This converter works from SoundFont 2 instruments only.

sf2toxrni supports :
  • envelope volume release
  • sample panning
  • sample looping
  • sample tuning (base note, fine and coarse tuning)
  • key mapping
  • velocity mapping
  • low pass filter cutoff
  • chorus amount
  • reverb amount
sf2toxrni does not support :
  • vibrato
  • initial volume attenuation (always minus infinite in result, it seems like it’d be a pita to support otherwise)

sfztoxrni

Similarly to the sf2toxrni converter, sfztoxrni convert SFZ files into renoise instruments (.xrni). Renoise supporting now natively SFZ files, this converter is only useful on SFZ instruments needing more than one modulation set (different ADHSR settings depending on the velocity/key mapping) or a more aggressive sample filename search (like for SFZ built under case insensitive filesystem and read in case sensitive filesystem). As SFZ support in Renoise will progress, this converter will be deprecated.

usage: sfztoxrni [-h] [-d] [-e {none,flac,ogg}] [-f] [-q] [-o OUTPUT_DIR]
                 [-t TEMPLATE] [-u] [--no-unused]
                 sfz_filename [sfz_filename ...]

xrnitag

xrnitag is a command line utility to manipulate tags in renoise instruments (.xrni). It can read, clear, remove or add tag to the tag list in one or more xrni files. If you want to edit a tag, you can remove it and then add the new one. xrnitag is compatible with renoise 3.0+ instruments and intercompatible with “instrument info” tool ( http://forum.renoise.com/index.php/topic/43434-new-tool-30-instrument-info/ ).

usage: xrnitag [-h] [-d] [-a TAGS_TO_ADD] [-c] [-r TAGS_TO_REMOVE] [-v]
               xrni_filename [xrni_filename ...]

GPL v3+ 2016 Olivier Jolly

positional arguments:
  xrni_filename         input file in XRNI format

optional arguments:
  -h, --help            show this help message and exit
  -d, --debug           debug parsing [default: False]

                        remove a tag
  -v, --view            view all tags [default action]

Display or change XRNI tags

xrniorganise

xrniorganise is a command line utility to organise your renoise instruments (.xrni) by tags. It creates a view of your instrument library using instrument tags, until renoise features a native tag powered instrument library search. Using symbolic links to create instruments views, it is only compatible with unix OSes (patches for supporting other OSes are welcome).

Instruments which aren’t tagged at all will be linked into the “untagged” directory.

Note that you can incrementally populate your library view, as xrniorganise will not remove existing instruments. It also means that if you switch a tag from old to new and run xrniorganise again, your instrument(s) will be linked both in the old and new directories. When you rename or remove tags, you can use the -c command line argument which makes so that your destination directory is cleaned before having any link created.

Directory cleaning attempts to be as conservative as possible (it’s a recursive removal after all, it could damage stuff if broken) by only removing symbolic links and empty directories. It implies that any regular file you’ll place inside the destination directory will abort cleaning.

Here is an example session:

# initially, we have some untagged, unsorted xrni files

$ find unsorted_xrni/ sorted_xrni/

unsorted_xrni/
unsorted_xrni/0_Arco Strings.xrni
unsorted_xrni/6_Zip.xrni
unsorted_xrni/0_Flute.xrni
unsorted_xrni/8_Oboe.xrni

sorted_xrni/

# we tag them with xrnitag CLI (or "instrument info" tool)

$ xrnitag -a orchestral unsorted_xrni/0_Arco\ Strings.xrni unsorted_xrni/0_Flute.xrni unsorted_xrni/8_Oboe.xrni
$ xrnitag -a sfx unsorted_xrni/6_Zip.xrni
$ xrnitag -a woodwind unsorted_xrni/0_Flute.xrni unsorted_xrni/8_Oboe.xrni
$ xrnitag -a loop unsorted_xrni/6_Zip.xrni unsorted_xrni/8_Oboe.xrni unsorted_xrni/0_Arco\ Strings.xrni

# them, we create a library view based on those tags

$ xrniorganise -o sorted_xrni/ unsorted_xrni/*

# now, you can see links to actual instruments based on their tags

$ find unsorted_xrni/ sorted_xrni/

unsorted_xrni/
unsorted_xrni/0_Arco Strings.xrni
unsorted_xrni/6_Zip.xrni
unsorted_xrni/0_Flute.xrni
unsorted_xrni/8_Oboe.xrni

sorted_xrni/
sorted_xrni/woodwind
sorted_xrni/woodwind/0_Flute.xrni
sorted_xrni/woodwind/8_Oboe.xrni
sorted_xrni/loop
sorted_xrni/loop/0_Arco Strings.xrni
sorted_xrni/loop/6_Zip.xrni
sorted_xrni/loop/8_Oboe.xrni
sorted_xrni/sfx
sorted_xrni/sfx/6_Zip.xrni
sorted_xrni/orchestral
sorted_xrni/orchestral/0_Arco Strings.xrni
sorted_xrni/orchestral/0_Flute.xrni
sorted_xrni/orchestral/8_Oboe.xrni

Here is the summary of all options:

Library use

Current, only renoise instrument API is available. A renoise instrument is represented by the RenoiseInstrument class and can be loaded that way:

from rnsutils.instrument import RenoiseInstrument
# load an instrument from an existing xnri
inst = RenoiseInstrument('existing.xrni')
# now, inst.root is an objectified xml tree you can access and alter
# inst.sample_data is a mutable list of audio files content
inst.save('new.xrni')
