Guitar to MIDI Converter
AI-Powered · Electric, acoustic, and DI guitar · 2 free trial credits on signup
Upload a guitar recording and PureMIDI uses an AI audio transcription engine to detect pitch, on/off times, and velocity, exporting a clean .mid file. Works with electric, acoustic, and DI pickup signals — open the result directly in Logic, Ableton, Reaper, FL Studio, GarageBand, or import to Guitar Pro for tab.
Upload audio
Choose a supported file, then convert it to MIDI.

Formats: MP3 / WAV / M4A / FLAC / OGG / WEBM / AAC. Max 12MB.
How it works
- 01
Upload your guitar recording
DI takes, mic'd amps, phone recordings, or audio interface bounces — drag and drop any audio file up to 12MB.
- 02
AI detects pitch and timing
Single-note riffs, solos, and picking patterns are most accurate. Polyphonic chord strums may have some notes missed due to detection limits.
- 03
Edit in your DAW or Guitar Pro
Download the .mid file and drop it into Logic, Ableton, Reaper, FL Studio, GarageBand, or import to Guitar Pro to convert into tab and notation.
Use cases
Capture riffs fast
Record a riff the moment it lands, get an editable MIDI draft in seconds — never lose a song idea again.
Transcribe guitar solos
Convert guitar solos to MIDI for note-by-note study, transposition, and arrangement.
Generate Guitar Pro tab
Import the MIDI into Guitar Pro to auto-generate tab and standard notation.
Layer with virtual instruments
Keep your original guitar tone and double the part with synths, brass, or 8-string libraries from the same MIDI.
Guitar recording accuracy notes
- DI or clean tones give the highest accuracy. Heavy gain and distortion add harmonics that blur pitch detection.
- Single-note riffs and lead lines are far more accurate than chord strums.
- 12-string guitars and double-tracked recordings produce overlapping pitches that need cleanup after export.
- Alternate tunings (Drop D, Open G) are detected at absolute pitch — adjust track tuning in your DAW or Guitar Pro to match notation.
Recording setup vs accuracy
How you record directly determines MIDI accuracy.
| Recording method | Tone | Accuracy | Notes |
|---|---|---|---|
| Electric guitar DI (no amp sim) | Clean | ★★★★★ | Best results |
| Electric guitar DI + light overdrive | Light gain | ★★★★ | Recommended |
| Electric guitar + mic'd clean amp | Clean | ★★★★ | Recommended |
| Acoustic guitar with mic | Natural | ★★★★ | Watch for pick noise |
| Electric guitar + high-gain / distortion | Metal / rock | ★★ | Single-note riffs only |
| Phone or camera recording | Mixed with room sound | ★★ | Background noise reduces accuracy |
Practical tip
If you want to capture a chord progression, don't strum the chord — arpeggiate it. Polyphonic pitch detection accuracy drops as more notes ring at once.
Frequently asked questions
Is the guitar to MIDI converter free?+
Free trial — sign up for 2 free trial credits, valid 30 days. No subscription. Continue with one-time credit packs (no expiration); see /pricing for current packs.
Which guitar recording formats are supported?+
MP3, WAV, M4A, FLAC, OGG, WEBM, and AAC. Maximum file size is 12MB on the free tier.
Will it work on a distorted electric guitar recording?+
Yes, but accuracy drops. Heavy gain adds harmonics that blur pitch detection. The cleanest workflow is to record DI, convert to MIDI here, then re-amp the original audio or play virtual amp tones in your DAW.
Does it detect chord strums as polyphonic MIDI?+
The engine is polyphonic, but six-string strums often miss or mis-detect notes that ring simultaneously. For accurate chord transcription, arpeggiate the chord rather than strumming.
Can I import the MIDI into Guitar Pro?+
Yes. Guitar Pro 8+ imports .mid files directly and converts them into tablature and standard notation automatically. Adjust track tuning after import for alternate-tuning songs.
Will it work on bass guitar too?+
Yes. Bass is almost always monophonic so detection accuracy is very high. Upload a bass recording on this same page.
Does it support alternate tunings like Drop D or Open G?+
The engine detects absolute pitch, so the tuning itself doesn't matter. Output MIDI is written using standard-tuning note names — set the track tuning in your DAW or Guitar Pro to display tab correctly.
