So its almost complete

Hey guys!

Just pushed v1.8.0 of REAPER-Notator, and it brings some much-requested workflow upgrades:

We now have an integrated MIDI Velocity & CC Lane Editor docked right on the screen. You can tweak velocities with handles, draw smooth linear CC curves (all 128 CCs supported), and interact with your automation in real-time for super fast iterations.

On top of that, Real and Fake Portamentos (hold-blending) and Glissandi are now fully implemented and audible in playback!

Also, huge thanks to everyone who reported issues with the SINE Player — the note audition and preview bug is officially solved and working cleanly now. Under the hood, the entire playback engine was overhauled to stay pinned at 30–70+ FPS even with 30+ tracks running.

🎉 REAPER-Notator is officially out!

Update to 1.5 for latest Hotfixes pls

Hey everyone!

After months of intensive development, planning and testing, I am super excited to present the official **REAPER-Notator Release**!

REAPER-Notator is a free, open-source, full-featured native music notation and engraving suite running directly inside Cockos REAPER via ReaImGui and standard SMuFL vector engraving (Bravura).

Instead of clumsy window switching, export-bridges, or clunky external apps, REAPER-Notator connects classical music engraving standards (*Elaine Gould / Behind Bars*, *Gardner Read*) directly to REAPER’s MIDI engine and CC automation.

### 🎼 Key Features

* **Standard-Compliant Music Engraving**:

* Crisp 60 FPS vector score canvas using Steinberg's SMuFL font (*Bravura*).

* Strict measure division (half-bar rule), automatic beam grouping with slope compensation, ledger lines, and accidental collision avoidance.

* Complex tuplets (triplets, quintuplets 5:4, sextuplets, septuplets, etc.) with automatic beam and bracket handling `[ n ]`.

* **16 Polyphonic Voices per Track & Auto-Voice**:

* Independent voices per track with distinct voice coloring, voice filtering, and ghost note rendering.

* **Auto-Voice** engine: Automatically splits overlapping polyphonic chords and counterpoint into separate voices with proper stem directions (Voice 1 stems up, Voice 2 stems down) – track-wide or on selection.

* **Score-Wide Vertical Fermatas (v1.4.1)**:

* 4 SMuFL fermata types: Standard, Short (triangular), Long (square), and Very Long (double arc).

* True score-wide vertical alignment across all staves.

* Non-destructive **Tempomap Slowdown Coupling**: Smoothly dips the project tempo during playback (1.25x–3.0x) and automatically restores it.

* **Interactive Rehearsal Marks & Navigation**:

* Rehearsal Marks ([A], [B], [C]... or [1], [2], [3]...) with automatic chronological re-sequencing.

* **Interactive Drag & Drop** directly along the Rehearsal Lane with real-time snap guides and measure downbeat targeting.

* Dedicated navigation symbols: *Da Capo* (D.C. / D.C. al Fine), *Dal Segno* (D.S. / D.S. al Coda), *Segno*, *Coda*, and *Fine*.

* **Dynamic Automation & CC Expression Curves**:

* Dynamic markings ($ppp$ through $fff$) automatically generate matching CC1 (Modulation), CC11 (Expression), and CC7 (Volume) curves.

* Hairpins ($crescendo$ / $diminuendo$) with linear and exponential curves.

* Asymmetric **Bow Swell** curve generator with adjustable peak positions.

* **Arpeggiated Chords & Micro-Strumming**:

* Authentic wavy line engraving (upward and downward with arrowheads).

* Non-destructive micro-strumming playback offset (15–30 ms) to emulate authentic harp, guitar, and keyboard strumming.

* **Rearticulate 2-Way Integration & Articulations Drawer**:

* Seamless two-way integration with [**Rearticulate**](https://reaticulate.com/) ([GitHub](https://github.com/jtackaberry/reaticulate)) bank files – assign key switches, techniques, and program changes directly from the score palette.

* **Chord & Scale Lane**:

* Automatic lead-sheet parsing (e.g. `Am7`, `Cmaj9`, `G7(b9)`, `D dorian`), scale snapping, and batch transposition.

* **Orchestral Pattern Browser**:

* Built-in browser with **1,050 orchestral, string, and harp patterns** across 8 categories with 1-click audio preview and drag-and-drop insertion.

* **Full MusicXML 4.0 & Vector PDF 1.4 Export**:

* Lossless two-way **MusicXML 4.0** import and export (tracks, voices, chords, fermatas, dynamics, rehearsal marks, text items).

* Native pure-Lua **Vector PDF Export** with title page, orchestrator notes, and 5-bar paginated score pages.

So close.... final debugging has started. 40 new features

I have integrated like plus 40 new features, and i think i need to create also a fully fledged documentation of all functions as well as videos. Best bit so far: New Midi Pattern Browser. Ive invested over a 1000 dollars into this dev so far, and it really has come far .. almost a full fledged industry standard notation editor for realistic playback. It will stay free forever.

  • Score Engraving: 60 FPS native ReaImGui vector rendering with Bravura (SMuFL), multi-track score view, automatic Grand Staff detection, and standard notation rules (proper rest decomposition, tuplets, beams, ties, slurs).
  • 16-Voice Polyphony: Dedicated voice channels (1–16), automated overlap splitting (Auto-Voice), smart pitch conflict resolution, and adjustable ghost note opacity.
  • Dynamics & Expression: Integrated CC1/CC11 dynamic markers, scalable hairpins, Bézier curve text dynamics (cresc./dim.), CC64 sustain pedal lines, and octave transpositions (8va/8vb).
  • Pattern Browser: 1,000+ curated orchestral patterns, live auditioning through any chosen project instrument, canvas drag-and-drop with alignment ghosts, and custom MIDI capture.
  • Editing & Integration: Mouse draw & keyboard step-input (C–B), note auditioning, universal clipboard, advanced quantization, shortcut manager, and full REAPER undo & project persistence.

Free Reaper Notator is on track and hopefully released in some weeks on Rea Pack

So this is a small update of the video and sneak peak that i have dropped two days ago.. I had a great breakthrough yesterday which seriously reduces the development time. So i believe for now all remaining bugs can be removed within the next few weeks to be able to release a first version of this on ReaPack.

Rearticulate can now be used as a direct extension of Reaper Notator, which is fantastic. (as a disclaimer: i have not changed anything in rearticulate, i also found a nice way to read out the bank values of the rearticulate bank settings file. )

ReaFlex: a free integrated vocal re-synthesis program for Reaper

Hi guys!

I've been a long time Reaper user for about the last 16 years, and I've created ReaFlex to fill a gap I've had in convenient vocal re-synthesis and re-pitching.

I wanted it to be working from right within Reaper's dock, and to seamlessly work with the existing systems.

It started as a frontend for ReaPitch in the form of a lua script, but I wanted to take it further, and made a ReaFlex resynth backend in JSFX. It defaults to the ReaFlex resynth backend, but you can choose Reaper Native (ReaPitch) if you want to use the front end only!

It's pretty early on, but I've come a long way in the last month with the use of AI. I would like to be upfront about that. It hasn't been a matter of "make melodyne 2 please", I've done a tremendous amount of testing and diagnostics. That being said, I understand if it puts you off.

So far you can:

  • Analyse a clip (The analysis side isn't 100% at the moment, so some fiddling can be necessary if it comes out awkwardly)
  • Pick a scale
  • Move notes up and down
  • Delete/Merge/Split/Create notes
  • Centre pitch
  • Smooth or exaggerate vibrato
  • Make manual glides between notes, otherwise it defaults to crossfades which usually sounds more natural
  • Render take if you'd like to save space
  • Have your edits persist between Reaper sessions, as the data is saved right to the project file

You can find a (very rough) demo on the website: https://amicodingwell.github.io/ReaFlex/#demo

Here’s the download link (it’s about one megabyte in size!):

https://github.com/amicodingwell/reaflex/releases

If you would like to help by providing vocal takes it can help the analyser tremendously, otherwise I'd love to hear any feedback. :)
