Migrated ModArchive and modLand functions to the
openmpt package
ProTrackR v0.4.3
Added pkgdown website and README
switched to RMarkdown mode for roxygen2 documentation
ProTrackR v0.3.8
Updates to comply with latest CRAN policies and Roxygen2
standards
ProTrackR v0.3.7
Fixes to modArchive functions, due to changes to their API
Fix in structure and examples to pass CRAN tests.
Fix in validation functions in order to support changes in latest
version of R
ProTrackR v0.3.6
Added modLand helper functions.
Reading and writing 8svx samples with read.sample and write.sample
is now implemented using the AmigaFFH package, which has a more robust
implementation of Interchange File Format handlers.
Added a ‘mix’ argument to the ‘modToWave’-method. When set to FALSE,
the method can now return all individual channels (without mixing
them).
The ‘playWave’-method was updated such that it also accepts
multi-channel waves (WaveMC), in order to make it compatible with the
modification specified above.
Available documentation on which of the 4 channels are mixed to the
left and right audio output channel respectively is inconsistent. This
version will assume that channels 1 and 4 (or 0 and 3 using Amiga
indexing) are mixed to the left channel and channels 2 and 3 (or 1 and 2
using Amiga indexing) are mixed to the right channel. This means that
the output channels are now swapped compared to earlier versions of this
package.
There was a bug in the implementation of the ‘porta to note’ effects
(3 and 5), it is now fixed.
Added a new implementation of the generic ‘as.raw’ method, which
allows to convert PTModule objects into raw data. Also added a
‘rawToPTModule’ method to achieve the inverse.
Endianess should have been set to “big” instead of “little”
(whoops), luckily, this has no consequences as all data are read as raw
data. I have corrected the code nonetheless
Minor corrections to manual
ProTrackR v0.3.5
Added functions to exchange pattern data with MODPlug tracker.
Endianness is explicitly set to “little” when reading and writing
samples and modules. As all data is read and written as raw, this should
not affect the package functioning.
Removed unnecessary print statement from PTBlock routine.
Fixed a bug in the ‘rawToCharNull’ function.
Fixed a bug in the ‘modToWave’ routine that caused an error under
rare conditions.
Setting stereo.separation to 0 was not handled correctly in
‘modToWave’ routine. Channels were not mixed before converting to mono.
This is now fixed.
ProTrackR v0.3.4
added a “fix.PTModule” method that attempts to fix a module object
when it is not conform ProTracker specs…
period limits for the porta effects have been fixed
inverted the logical interpretation of the ‘verbose’ argument, as it
was incorrect in earlier versions.
added and modified several of the ‘modArchive’- functions, for
better support from modarchive.org
modified S4-object validation functions such that they run
faster.
modified ‘write.module’-method such that it will write modules much
faster
fixed bug in ‘read.module’-method and modified it such that it will
read modules much faster.
fixed bug in ‘loopStart<-’-method
fixed bug in ‘loopLength<-’-method
fixed bug in ‘patternOrder<-’-method
fixed bug in ‘appendPattern’-method
fixed bug in ‘volume<-’-method
fixed bug in ‘waveform<-’- and ‘waveform’-method
ProTrackR v0.3.3
Minor correction in manual.
ProTrackR v0.3.2
Minor corrections in manual.
ProTrackR v0.3.1
Modified the playing routine such that the porta effects can’t slide
period values below that of note B-3 or above 856. Period values are
cut-off at these values after processing the other effects as well.
Thanks must go to Olav Sørensen (who created a Protracker v2.3D clone
for modern machines, https://16-bits.org/pt.php) for confirming these
software and hardware limits.
Resampling routine in the modToWave-method is rewritten. It should
be faster now.
The 9xy command is now implemented such that it emulates the
ProTracker ‘offset bug’. Therewith, the player routine now passes
‘ptoffset.mod’ test.
Bug in resampling of samples in ‘modToWave’- routine is fixed.
‘modArchive’ functions are added to the package.
Effect commands ‘E4x’ and ‘E7x’ are now implemented in the player
routine.
Implementation of effect command ‘5xy’ is fixed.
In the previous release, some generated wave data ended up out of
range in the mixing procedure. This is now fixed.
The ‘playWave’-method is modified such that it returns an
‘audioInstance’-object (audio package) allowing control over the
playback.
Minor corrections/improvements to the manual
Mixing when some tracks are turned off is fixed
ProTrackR v0.2.3
Minor corrections in manual to pass CRAN checks.
ProTrackR v0.2.2
Minor corrections in manual to pass CRAN checks.
ProTrackR v0.2.1
‘clearSamples’-method was added to the package.
‘clearSong’-method was added to the package.
‘modToWave’-method was added to the package
‘playingtable’-method was added to the package
‘playMod’-method was added to the package
‘playWave’-method was added to the package
‘resample’-function added to the package to avoid ‘seewave’
dependency (which is not available for all platforms).
‘waveform’-method now includes additional arguments: ‘start.pos’,
‘stop.pos’ and ‘loop’
removed ‘utils’ import…
‘name’ method, for PTSample objects, incorrectly returned raw
representation of the sample name instead of a character representation.
This is now fixed.
‘playSample’ was printing the names of additional (…) arguments in
previous release. This was meant as a test and this behaviour was not
intended for the release. It has been removed.
A section on ProTracker effect commands is added to the manual
Some minor corrections were made in the manual
ProTrackR v0.1.3
Some more minor fixes to pass CRAN checks.
ProTrackR v0.1.2
Minor fixes to pass CRAN checks.
In the ‘playSample’ method, the ‘finetune’ argument is now correctly
passed to the ‘noteToSampleRate’ function. Before, it was only possible
to play at the finetune specified for a sample.
Correction in the validity check for objects of S4 class ‘PTSample’:
wlooplen is allowed to have a value of zero when the sample is
empty.
The prototype of the S4 class ‘PTSample’ is changed to set the
wlooplen value to zero.
The slot descriptions for wloopstart and wlooplen in the ‘PTSample’
documentation contained errors that were corrected.
The ‘loopLength<-’, the ‘PTSample-method’ and ‘read.sample’
methods were modified to handle the adjustments to the ‘PTSample’
class.
Removed superfluous argument ‘value’ from the ‘patternLength’
method
ProTrackR v0.1.1
First release:
Provided the basis for importing, exporting and manipulating
ProTracker modules.
Basic playing routine, playing the samples in the module only (not
the module itself).
