xtc screenshots

The main gallery was refreshed after Phase 68 on 2026-11-06. Two additional Phase 79 captures show the new sample editor and transient markers. These are actual rendered application windows and menus on a 1440 × 960 virtual X11 screen, without mockups, compositing or image edits.

The temporary demonstration project starts from examples/projects/modern-session.xtc, adding Intro/Verse/Chorus/Outro markers, a routed music bus and gain automation. Editing results use the real control APIs and GUI history/preparation paths. Original projects, media and user configuration are not overwritten. Black margins are the virtual desktop; floating views show the actual detached windows together.

New arrangement and composition workflows

Phase	Feature	Captures
58	Persistent named arrangement markers	Ruler, marker editor
59	Section navigation and looping	Current section loop
60	Ripple time insertion/removal	Controls, inserted gap
61	Complete track duplication	Independent layered track
62	Nondestructive MIDI splitting	Split clip
63	MIDI clip consolidation	Consolidated clip
64	Seeded MIDI humanization	Timing, velocity and seed
65	Chord construction	Intervals, generated notes
66	Offline arpeggio generation	Step, gate and direction, written pattern
67	Audio peak normalization	Target dBFS, normalized clip
68	Portable media collection	New destination folder

Collection is also executed by the capture tool into its temporary directory; the screenshot shows its destination prompt, not a file browser or progress UI. See COMPOSITION_WORKFLOWS.md for precise behavior, limits and commands. The screenshots illustrate implemented workflows; they do not establish feature parity with other DAWs.

Audio source editor (Phases 69–79)

• Frame selection, waveform, statistics and processing controls
• Detected source attacks and clip slicing controls

These captures show the actual modal editor with the repository pluck WAV. Processing is staged locally; Save full copy and relink applies it to the project. See AUDIO_EDITOR.md for limits and frame/tick rounding.

Refreshed application views

All pre-existing images below were recaptured. Mixer playback meters come from real JACK callbacks. The minimum-size capture uses a 1220 × 720 main window; the scrolled view adds twelve tracks. Audio views import the repository's original-pluck.wav and apply clip gain/fades. Plugin views use repository test fixtures, not commercial plugins. Internal instrument menus and delay/reverb editors show the real available devices and controls. The command palette uses the current application action list.

Detach panels from the View menu; close a floating window or use its Dock button to return it to the main window.

Reproduce the gallery

From the repository root, run:

make BUILD_DIR=build/next-daw screenshots

This optional documentation target requires the existing FLTK/JACK build prerequisites, a running JACK server, Xvfb (xvfb-run), ImageMagick (import) and xdotool. It builds the repository plugin fixtures, runs the capture tool, and replaces the gallery PNGs. All demonstration edits and collection outputs use an automatically removed temporary directory; no preferences are saved. It neither installs dependencies nor starts/reconfigures the audio server.

Set XTC_CAPTURE_SAMPLE_ONLY=1 for the capture tool (or the make target) to write only the two sample-editor images while retaining the existing gallery.
