v0.3.1

VLTONE 0.3.1 adds drawn slide notes, sampler Slide / Legato and an updated Piano Roll. Replace samples directly from the note editor, generate chords in an empty clip, automate Master and bounce several tracks into one audio clip. The render window and AI chat have been redesigned, with fixes for MIDI clip trimming and sampler note transitions.

Melodies

Draw your pitch transitions

Shape pitch transitions inside a phrase. Draw curves, change their shape and hear the result without retriggering the sound.

Read moreShow less: Draw your pitch transitions
  • Slide notes are separate control objects in MIDI clips. The Piano Roll Slide tool and key 6 create pitch transitions without generating their own Note On or retriggering the sounding voice.
  • Draw pitch curves with several rises and falls in one note. Use nodes, Pencil, segment curvature, time/pitch snapping and numeric values. Double-click opens a nonmodal curve editor.
  • Linear, Smooth, Wave and Return presets, shape-only copy/paste adapted to duration, and linked-phrase audition. Esc cancels a gesture; one completed gesture creates one Undo action.
  • One Note / Chord modes retain linked voices. Chord slides apply the same interval while preserving voice spacing. Consecutive and overlapping slides continue from the reached pitch, which holds after the transition.
  • Preview linked notes before creating a slide, view the actual trajectory and identify inactive slides and hatched tails. Rebind or extend the base note with explicit commands.
  • Instrument slide delivery: Auto, Per Note, MPE, Pitch Bend and Off. Modes depend on confirmed capabilities. Range, channel-wide Pitch Bend effects, limitations and MPE overload are visible. MPE uses channels 2–16 and retains bend through release.

Drawn slide curve: multiple pitch movements, precise values and shape controls.

Instruments

Slide and Legato in Sampler

Connect overlapping notes smoothly and replace a sample directly from Piano Roll while keeping your instrument settings.

Read moreShow less: Slide and Legato in Sampler
  • Sampler Slide / Legato page: monophonic transitions between overlapping notes, last-note priority and return to a previously held note. Choose 0–2000 ms or musical divisions, linear/S-shaped motion, 0–20 ms switch smoothing and incoming MIDI Pitch Bend range.
  • Replace a Sampler source by dropping one audio file from the browser onto the Piano Roll grid. Instrument settings are retained; in patterns this targets the open source’s sampler. Undo / Redo is supported. Third-party MIDI instruments are not replaced.

Chords

Start a chord from an empty clip

Choose a root, chord type and inversion. The generator can create a chord even when your clip has no notes yet.

Read moreShow less: Start a chord from an empty clip
  • Chord Generator can create a chord in an empty clip: root, type, inversion, bass doubling, start, length and velocity. Selection-based operation remains available; preview is applied as one action.

Mixing

Automate your Master channel

Shape volume, pan and master plugin parameters with automation curves on the timeline.

  • Master automation for volume, pan and master-plugin parameters. Show Master on the timeline and create child automation curves from its mixer menu; the inspector exposes its controls too.

Arrangement

Bounce several tracks together

Render selected tracks into one audio clip. Fold a long session into compact tracks while keeping its contents in view.

Read moreShow less: Bounce several tracks together
  • Combined Bounce in Place renders selected tracks or clips into one audio file on a new track. Sources share the same audio graph; rendered source regions are muted. The operation is undone as one action.
  • Double-click a track name or empty header area to toggle compact height and restore its previous size. Selected-track minimize/restore commands and content overviews in collapsed folders are available.

Note editing

A clearer Piano Roll

Choose a MIDI clip, adjust the zoom and edit notes in the updated workspace. Scroll freely through your phrase during playback.

Read moreShow less: A clearer Piano Roll
  • Piano Roll has compact slide and clip selectors, consistent panels, refreshed keys, a top horizontal scrollbar and zoom controls on the right. Chords… moved to the footer and supports Alt+B.
  • Double-clicking an empty MIDI track creates a clip without opening the editor. Double-click the clip to edit it. Maximized Piano Roll stays to the right of the inspector and below the context panel.
  • Piano Roll no longer follows the playback cursor automatically, allowing free navigation through a phrase during playback.
  • MIDI and Pattern clips trim from both edges without shifting the source phrase. Piano Roll retains the full source and dims the hidden head; extending the left edge restores hidden notes.

Updated Piano Roll: compact toolbar, top scrollbar and zoom controls.

Export

Your export on one screen

Format, range, processing, stems and metadata are together in one place. The summary and progress stay within reach.

Read moreShow less: Your export on one screen
  • The render window combines format, range, processing, stems and metadata on one page. Wide windows use two columns and narrow windows one; summary, progress and actions remain available at the bottom.
  • Audio export and Freeze use the shared slide playback calculation. MIDI-file export retains ordinary notes and warns that drawn slide curves are not included.

New render window: format, range, processing, stems and metadata on one page.

AI assistant

A chat that fits your workspace

Updated messages, input and clear actions with tooltips, all styled to match the VLTone workspace.

  • AI chat follows the application’s visual style, with refreshed messages and input, icon-based Copy / Edit actions and tooltips. Starter suggestions have been removed.

Other changes

  • Project format 11 stores slides separately from ordinary notes. Older projects load with empty slide collections. Shared slide editing requires protocol 5 support on both client and server.

Bug fixes

  • Fixed custom text entry immediately after opening AI chat. A message can be sent without selecting a suggested action.
  • Sampler slides retain source position, envelopes, filter and Stretch processor state. After the base note ends, its natural release keeps the last reached pitch.
  • Reduced clicks when Cut Itself retriggers a note: the outgoing voice fades briefly and the new voice has a matching onset. Fixed fade behavior when leaving Loop.
  • Master automation now reaches the actual master channel and plugins and restores after project load or graph rebuild. Master automation tracks are correctly placed on the timeline.
  • Note audition works when drawing new notes and playing onscreen keys. Selection, movement, resizing, copying and Undo no longer trigger unwanted sound; mouse release and focus loss stop audition.
  • Fixed playback placement, controller state, takes and MIDI export after trimming a MIDI clip’s left edge. AI context excludes notes outside the audible region.
  • Improved VST3 state preparation for offline rendering, including instruments such as EZdrummer. Fixed related playback/export differences.
  • Refined Russian render labels and tooltips, short/narrow window layouts, interface scaling and compact-track mouse interactions.
