v0.4.0
0620c42

Version 0.4.0 combines instrument and sample lists into a single BrrSample list and rewrites the samples tab.

To simplify sample creation, the new samples tab automatically tunes newly created samples and allows the user to drag & drop an external file into the samples list.

Changelog

BREAKING CHANGES::

  • The .terrificaudio file format has changed.
    • TAD will automatically convert .terrificaudio files to the new format.
    • The new format is incompatible with TAD v0.3.0 and earlier.

Audio driver changes:

  • The 256 pitch table entry limit has been removed.
    The pitch table offset is now 16-bit.
  • The instrument ID is now equal to the S-DSP VxSRCN BRR sample index.
  • Added main-volume setting to the song-data and bytecode.
    • The echo_i8 bytecode instructions have been renamed to global_i8.

Project Changes:

  • Instruments and samples have been merged to a new BrrSample data structure.
    • Sample source, pitch-table and envelope data are now separate structs.
    • TAD v0.4.0 projects are not compatible with 0.3.0 and below.

GUI changes:

  • The samples tab has been rewritten.
  • Added a "Open new sample" button to the samples tab (located above the sample list).
  • The samples tab now automatically tunes the sample after opening the source file.
  • Added drag and drop files to the samples tab.
    • Dragging a single file onto the samples tab list will create a new sample using that file.
    • Files cannot be dragged into the editor widget.
  • The sample analyser window and samples tab have been merged.
  • The sample analyser spectrum now uses logarithmic scaling.
  • Fixed the sample analyser outputting a 0Hz peak on biased samples
    (ie, a square wave with no negative values).

MML Changes:

  • The MML compiler now merges @ instrument and A ADSR envelope commands
    into a single set_instrument_and_adsr bytecode instruction.
  • The MML compiler now merges @ instrument and G GAIN envelope commands
    into a single set_instrument_and_gain bytecode instruction.
  • Added the #MainVolume MML header.
  • Added \mvol, \mvol+ and \mvol- MML commands (set/increment/decrement main volume).

Bytecode assembly changes:

  • Added set_main_volume.
  • Added adjust_main_volume.
  • Added adjust_main_volume_limit.

BRR encoder changes:

  • Dupe-block-hack now accepts non-zero loop points.
