Audio-to-MIDI Transcription Plugin. You play or sing something — it listens, analyses the audio, and converts it into clean MIDI notes that you can use in your DAW.

Drop in a guitar recording, a piano melody, a vocal line, a bass riff, or even a full instrument — Semedo Notes figures out which notes were played, when they started, how long they lasted, and how loud they were. It turns all of that into a MIDI file you can drag straight into your project.

No keyboard skills needed. No MIDI controller needed. Just play or sing.

AUDIO TO MIDI — THE CORE
Drop any audio file onto the plugin — WAV, AIFF, FLAC, MP3 or OGG — and Semedo Notes analyses it and produces a full MIDI transcription in seconds. It works on single instruments: guitar, piano, bass, voice, strings, flute, synth lead — any source where individual notes can be identified.

LIVE RECORDING
Hit the REC button while your DAW is running. Semedo Notes captures your live input — microphone or instrument — for up to 2 minutes and transcribes it the moment you stop. No need to bounce to a file first.

GHOST NOTE FILTER (unique to Semedo Notes)
This is what sets Semedo Notes apart from similar tools. Every AI pitch detector generates false notes — overtones, room noise, bleed, and artefacts that appear in the MIDI as notes that were never actually played.

The Ghost Filter automatically removes these:
– It detects and removes octave overtones (harmonics that sound above the real note but were not played independently).
– It removes low-confidence notes that are too quiet relative to the real notes in the same moment.
– It enforces a polyphony limit so chords stay clean instead of turning into a wall of unwanted extra voices.

The result is MIDI you can actually use without spending an hour deleting wrong notes by hand.

PURITY CONTROL
A single knob controls how aggressively the plugin cleans up the result. Turn it down to keep everything the model detected. Turn it up to keep only the notes the plugin is most confident about. You stay in control of the balance between completeness and cleanliness.

PITCH BEND / EXPRESSION EXPORT
Semedo Notes detects the micro-pitch movement in your playing — vibrato, slides, bends — and can write that expression into the MIDI file.

Three modes:
– Off — flat MIDI notes, works with every instrument.
– Mono safe — adds pitch bend for single-note lines where bends cannot conflict with each other.
– Per-note MPE — each note gets its own MIDI channel and its own pitch wheel. Perfect for MPE-capable instruments like Serum, Pigments, ROLI instruments, and MPE-aware samplers. The MIDI file declares a proper

MPE lower zone so it plays back correctly without manual setup. Bend range: ±2, ±12 or ±24 semitones, written into the MIDI via RPN messages so the receiving instrument knows how to interpret the data.

TIME QUANTIZE
Align the transcribed notes to your project’s tempo grid automatically. Semedo Notes reads the BPM directly from your DAW — no manual entry needed while a project is open. Choose your grid (1/4, 1/8, 1/16, 1/32, triplets) and set how strongly the notes snap to it: 0 leaves timing completely raw, 1 locks everything to the grid. If no DAW tempo is available (standalone use or imported files), a manual BPM fallback is available.

SCALE FILTER
Constrain transcribed notes to a musical scale. Choose any root note and scale type: Major, Minor, Dorian, Mixolydian, Lydian, Phrygian, Locrian, Blues minor, Minor pentatonic, Major pentatonic, Melodic minor, Harmonic minor, Harmonic major — 14 scales in total. Notes that fall outside the chosen scale are removed, not moved. Semedo Notes never invents notes or shifts pitches to force a result.

NOTE RANGE FILTER
Set a minimum and maximum MIDI note to ignore anything outside the range you care about. Useful for filtering out low-frequency noise that gets transcribed as bass notes, or keeping only the range of a specific instrument.

MIDI DRAG AND DROP
When the transcription is ready, drag the MIDI clip directly from the plugin into a MIDI track in your DAW. No export dialog, no file browser — just grab and drop it where you need it.

MIDI EXPORT
Save the clean MIDI to a file at any point. The export button opens a standard save dialog. The exported file includes the correct tempo, note velocities, pitch bend data (if enabled), and RPN messages for MPE receivers.

MIDI OUTPUT
Semedo Notes sends its MIDI output to your DAW in real time. Route the plugin’s MIDI to any instrument track and preview the transcription through any sound you like.

BUILT-IN PREVIEW INSTRUMENT
A lightweight built-in synthesiser lets you hear the transcription inside the plugin without any additional routing. 32 voices, clean sine wave with smooth attack and release, soft limiter to prevent clipping. When MPE is active, pitch bends are played back correctly per voice in the preview too.

WAVEFORM DISPLAY
The original audio waveform is displayed above the piano roll so you can see exactly which notes correspond to which part of the recording. The waveform stays aligned with the notes and the playback head as you zoom and scroll.

PIANO ROLL
A full piano roll shows all transcribed notes with velocity shading — louder notes appear brighter. Zoom in and out with the mouse wheel. The playhead moves in real time during preview playback.

RE-ANALYSE FROM ORIGINAL
The original audio is kept in memory after transcription. If you change the Detection Confidence or other model parameters, Semedo Notes can re-run the full analysis from the original recording without you having to drop the file again or re-record.

LOW CPU USAGE
All heavy processing — audio loading, resampling, AI inference — runs on a background thread. The audio thread does no analysis work, no memory allocation, and holds no locks. Your DAW stays responsive and dropout-free while Semedo Notes works.

SAFE DURING PLAYBACK
Semedo Notes never interrupts your DAW’s audio output. Analysis runs in the background. Results appear in the piano roll when ready. You can keep playing and recording in your project the whole time.

This is a tool that allows you to change the sound timing of drums you have created by playing them back and forth.

The pronunciation timing fluctuates according to the pitch and velocity settings of the MIDI signal,

Bass drums are pronounced earlier only when they become stronger.

– The hi-hat is pronounced slower only when it becomes weaker.

– The snare is always pronounced a little slower.

Grooves can be adjusted without manually fine-tuning MIDI tracks.

– Even if quantization is performed by changing swing values, etc.,

4D pocket groove designer can maintain displacement and randomization.

– Because it functions without moving the sound position on the sequencer,

the first note of a beat is pronounced a little before the beat. This makes it easy to edit drum tracks in which the first note of the beat is pronounced a little before the beat.

The goal is to make drums groove more naturally without manual MIDI editing.

Only Tested in Windows Studio One (May not work properly in other DAWs and Mac OS)

A VST plugin for enhancing non-MPE MIDI streams with MPE (MIDI Polyphonic Expression) capabilities based on user-defined mappings and rules, for Linux and Windows.
MPE Emulator is a MIDI proxy: an intermediary plugin which turns non-polyphonic, single channel aftertouch (channel pressure), pitch bend, or any MIDI Control Change (CC) message into polyphonic by applying them selectively to the lowest, highest, oldest, or newest note, either across the whole keyboard or restricted to a range of keys based on a configurable keyboard split point. It can also remap and reshape controller data, and do various other tricks to increase the expressiveness of a musical performance.

Features:

Retroactively add MPE functionality to non-MPE-capable MIDI input devices.
Remap controllers, e.g. turn modulation wheel data into MPE aftertouch and vice-versa.
Invert MIDI expression and controller data, and apply various other distortions.
Use the trigger velocity of notes as release velocity for synths that utilize it.
Split the keyboard and route polyphonic expressions to the two halves with different rules.
Transpose the two sides of the split point independently from each other. (E.g. extend the range of small keyboards, or play the same note with different expression settings.)
Route various expressions and controllers to the lowest, highest, oldest, or newest note globally, or across the split halves of the keyboard.

MPE Emulator Lite:

MPE Emulator Lite is a platform-independent JS plugin for REAPER v6.74 and above which provides the most fundamental features of MPE Emulator.

Installation:

Before Installing: Choosing a Distribution
If your plugin host application supports VST 2.4, then you should download and install the FST version of MPE Emulator.

If your plugin host only supports VST 3, or if you can live with a few quirks and edge case bugs due to the incomplete MIDI support in the VST 3 protocol, then you should try the VST 3 bundle on both Windows and Linux.

If you are using an older VST 3 host, or if you are running a 32 bit (also known as “i686” or “x86”) VST 3 host on a 64 bit Linux system, then it might not be able to load the VST 3 bundle, so you will have to go with a VST 3 single file MPE Emulator package that matches the architecture of your host application.

The 32 bit versions are usually only needed by those who deliberately use a 32 bit plugin host application, e.g. because they want to keep using some really old plugins which are not available for 64 bit systems.

If you are in doubt, then try the 64 bit FST version, and if your plugin host application doesn’t recognize it, then try the VST 3 bundle, and if that still fails to load, then try the 64 bit VST 3 single file version, then the 32 bit FST version, then the 32 bit VST 3 single file version, and so on.

System Requirements:

Operating System: Windows 7 or newer, or Linux (e.g. Ubuntu 22.04)
CPU: SSE2 support, 32 bit (i686) or 64 bit (x86-64)
RAM: around 30 MB per instance
The plugin can also be compiled for RISC-V 64 from its source code.

Tested with REAPER 7.17.

MPE Emulator Lite runs on any operating system and CPU where REAPER runs. The required minimum version of REAPER is v6.74.
