Before working on the arpeggio enhancements, I wanted to get some changes out into a tagged release for those who don't follow me on GitHub.

0.05wip6 (2017-06)

  • Patterns can change channel volume in 25% steps
  • Rest in attack track no longer corrupts pulse 1 arpeggio
  • Change engine's code and data segment; disable pulse channel effect pooling and volume comparison; change initial $4011 value
  • Optionally enable sound effects in NSF
  • Improved diagnostics emitted by play command. Shows song name; emits one for playing pattern too low.
  • Command line option to change output segment
  • Clamp vibrato depth to in-range values
  • Ignore loops in volume envelopes, presumably pasted from FamiTracker
  • NSF header gets load address from linker configuration
  • Document use of equal temperament
  • Add "Sticks" sample song

Pently 0.05wip7 has three key improvements: portamento, slow arpeggio, and richer ways to express arpeggio.

  • Change to zlib license, which preserves the spirit of the original license but is recognizable by GitHub
  • Add portamento, the single most requested feature
  • paldetect: Interleave with vwait so as not to depend on NMI handler
  • Add 8 predefined chord names (M, maj7, dom7, aug, m, m7, dim, dim7)
  • Score can define new chord names
  • Add single-note arpeggio syntax similar to LilyPond chord mode (thanks to retrodpc for testing)
  • Option to name chord by its top note instead of bottom
  • First and second inversions of chords
  • Arpeggio can be set to slow or fast (requested by w7n)
  • Add "Arpeggio Waltz" song demonstrating new features
  • Document that object names follow identifier rules
  • makefile: Launch Python tools with py.exe on Windows

Pently 0.05wip8 is expected to be the final release of this calendar year.

  • Reduce BSS (main RAM) footprint when several effects are off
  • Reduce ZP footprint when attack phase is off
  • Compress 0-pitch frames of instrument envelopes
  • correctly parse drum names starting with "l"
  • option to change overall tuning up or down from A440
  • special filename - means standard output
  • output lists each song's total size in comments
  • Add "Isometry" song demonstrating attack track more thoroughly
  • makefile: change score filename
  • NES shell: move copyright notice to status bar
  • NES shell: status shows ROM size and current and peak CPU usage
  • NES/NSF executables no longer in Git; will be in releases instead

Is anyone actually using this?

Personally, i mean to get into pently and try it out once i have one or two balls less to juggle, because it looks very promising. Separate attack portions make a lot of sense. Were you planning on a dedicated tracker?

I even prototyped effect symbols for a new tracker, but I too have many balls to juggle.

Based on discussion about conveniences for MML composers a few days ago, I've been adding enhancements to playback in Pently's NES shell (see bug 27).

  • Visualizer: See what notes are playing on the main pitched tracks and what pitch and volume are output on each channel
  • Rehearsal marks: Navigate to sections of a song
  • Track muting: Disable or enable note-ons on a track. This works on tracks, not channels, letting you (for instance) hear a channel's own track separately from drum and attack track overlays that play over it. I've even added the same double-click behavior as FamiTracker: solo if any other channel is unmuted; otherwise unmute all.
  • Resume point: When the ROM starts, jump to a specific row of a song with specific channels muted.

So here's an interim player release built from the head of my tree. Try it and see if my navigation, visualizer, and track muting are in any way helpful. Press A or B to switch between the song list and the visualizer. On the visualizer, use up and down to jump to a section or left and right to move to the mute controls.

Pently 0.05wip9 is out

This release adds several features useful for iterating on part of a piece, such as a visualizer, channel muting, seeking to rehearsal marks, and slow motion playback. It also adds an editor to create sound effects right on your console.

Engine changes

  • PENTLY_USE options to disable music engine entirely, disable 303 portamento, and enable triangle channel duty fix
  • Regression fix: Cancel injection when attack ends (had been broken since slow arps)
  • Cancel grace note when pattern begins
  • Add rehearsal transport control to skip to a row or slow down or pause playback
  • Add variable mix to mute tracks
  • Store current pitch and volume for use by visualizer changes

  • Add warning infrastructure
  • v1 through v4 as synonyms for pp through ff
  • p (pause) is synonym for r (rest)
  • q repeats last chord, as in LilyPond
  • Bar check in pattern to warn if not on a measure boundary
  • pickup works in patterns as well
  • Unreachable A in tunings below A=437 is nonfatal
  • mmloctaves off, which future chord syntax will require
  • Set rehearsal marks for navigation in score
  • Set initial playback position and track muting

NES shell changes

  • Add per-song screen with visualizer, rehearsal mark navigation, track muting, tempo, and pause-and-step
  • Import Sound Effects Editor as of 2014-09-10

Manual and other changes

  • Script to estimate pitch of 93-step noise
  • docs: Recalculate PENTLY_USE savings

One suggestion of thing to add could be the octave mode that < and > makes the octave permanent while ' and , makes the octave temporary (a few MML compilers support this).

Also, I do not see any description of the mmloctaves command in the documentation.
