Ample Sound has announced the release of an update to 14 of its guitar instruments. A free upgrade for existing users, Ample Guitar v4 comes with various improvements and a free Ample Guitar LP Fingerstyle library.
Changes in Ample Guitar v4
- Riffer 4: A MIDI editor tailored for plucked string instruments.
- All-new Strumming and Chord System: The innovative “Strum Note” treats multiple sub-notes within a chord as a single editable object, allowing unified control over strum time, velocity gradient, and legato parameters. Combined with authentic guitar fingering settings, this makes strum creation more intuitive and efficient, delivering results that are closer to real performance.
- Dual View Modes: Seamless real-time switching between Piano Roll and Guitar Tab views — a first of its kind, offering two perspectives for reviewing and editing the compositions.
- String Visualization System: Strings are now visualized within the Piano Roll, enabling MIDI writing that adheres to authentic plucked instrument techniques — automatically preventing polyphony on the same string and intelligently assigning fingering. The result is MIDI that sounds closer to real performance.
- Intuitive Technique Editing: Easily program fingering, articulation, legato, and expression — no need for cumbersome key switches or complicated MIDI CC programming.
- New MIDI CC and Velocity Editors: View and edit multiple MIDI CC lanes simultaneously with different colors and transparency. One-click CC curve presets allow fast and expressive automation.
- Full MIDI Import/Export Compatibility: Whether import external MIDI files or export from Riffer to DAW’s MIDI or instrument track, the playback result remains identical and accurate.
- Extensive Riff Library: Hundreds of brand-new guitar riffs to spark creativity and accelerate the workflow.
- Tab Reader 4: Compatible with Guitar Pro formats from GP3 to GP8. Capable of importing full guitar tracks into Riffer with all fingering, articulations, and performance data preserved.
- Ample Sound v4 Engine: Improved audio processing performance and efficiency.
- Brand New 5K UI Design.
- Completely Remade Presets: All presets have been redesigned for a more mature, polished tone. Each preset is paired with a Riffer demo for quick audition and inspiration.
- AGLP: Added a new fingerstyle sample library, recorded with a Gibson LP R9 electric guitar, adding 3.6 GB of new samples.
- AGSC: All four pickup position libraries now include new samples such as raking and slide FXs.
- AMH: Added Strummer.
- AME: Chord fingerings in Riffer and Strummer have been remade for consistent compatibility with other guitars.
