Articulation-aware Guitar Pro → MIDI

StringSync: Guitar Pro to MIDI Converter

A standalone desktop app that turns Guitar Pro tabs into MIDI your sampled guitars and basses actually understand — palm mutes, bends, slides and harmonics become the keyswitch notes, velocity ranges and pitch-bend curves your library expects.

Before / after

The same riff, two very different MIDI files

Guitar Pro's own MIDI export writes the notes. StringSync writes the performance — keyswitches, dynamics and pitch bend your sampled guitar can actually respond to.

MIDI export comparison — flat Guitar Pro export without keyswitches or velocity versus StringSync export with keyswitches and a full velocity lane

Straight out of Guitar Pro

  • No keyswitches — palm mutes, harmonics and slides reach the library as plain sustain notes.
  • Velocity carries almost no performance detail — accents, ghost notes and picking dynamics flatten out.
  • No library octave conventions — instruments that expect notes +12 play the whole part an octave off.
  • The pitch-bend range is never announced, so bends land wherever the plugin default happens to be.

The same tab through StringSync

  • Every detected technique emits the library's documented keyswitch — placed, held and released cleanly.
  • Written dynamics become velocity 15–127 with per-articulation offsets, optional humanization and open-string boost.
  • Notes transpose to each library's octave convention on export — keyswitches stay put.
  • Bends become pitch-bend curves, with the range written as RPN 0,0 at the start of every track.

From tab to DAW in six moves

Import, map, audition, export

No project files, no plugin chains, no DAW required for the conversion itself. StringSync keeps the whole job — tracks, techniques, timing and dynamics — visible in a single window.

01

Import the tab

Click Import GP or drop a .gp3–.gp file anywhere in the window. Tracks, tempo, key and every detected technique load into the articulation map.

02

Pick your library

Choose a factory preset — Shreddage, Odin, Ample, RealEight, Submission Audio and more — and the map fills with that library's keyswitches, hold behaviour and octave convention.

03

Review the map

Categories show what your file actually uses. Any technique can emit a keyswitch, force a velocity or stay a plain note — save the result as your own preset.

04

Tune the conversion

Keyswitch timing with or before the note, keyswitch velocity, humanized dynamics, open-string boost and the pitch-bend range written as RPN 0,0.

05

Audition the result

Slide up the MIDI preview drawer: a full piano roll with notes, keyswitches, bends and a velocity lane, auditioned with bundled clean and driven tones.

06

Export and produce

Export the .mid — or drag the Export button straight into a folder or your DAW timeline. Load it on a track with your library. Done.

StringSync MIDI preview piano roll — notes, keyswitches and velocity lane of a real 7-track song
The MIDI preview drawer on a real 7-track song: 5,969 notes, 6,091 keyswitches and a full velocity lane — before a single note reaches your DAW.

All product names are trademarks of their respective owners. StringSync is not affiliated with or endorsed by any of them — factory presets are compatibility references that emit only the MIDI events each library documents.

01

Articulations, not bare notes

Palm mutes, bends, slides, natural and artificial harmonics, hammer-ons, tremolo, trills, vibrato and dead notes translate into the events your library expects instead of being flattened away.

02

No sticky articulations

Plain notes automatically emit the library's sustain keyswitch, and every keyswitch is released just before the next one — so a palm-muted phrase never bleeds into your clean chorus.

03

A velocity engine, not a constant 96

Guitar Pro dynamics from ppp to fff map to velocity 15–127 with per-articulation offsets, optional humanization and randomization, plus an open-string boost for ringing strings.

04

Real bends, correct range

Full, half and quarter bends become pitch-bend curves that resolve and reset cleanly, with the bend range announced via RPN 0,0 so your plugin bends exactly as far as the tab says.

05

Octave conventions handled

Some libraries expect notes an octave above sounding pitch. StringSync knows which — notes transpose on export, keyswitches never move, and the preview always plays at true pitch.

06

Verified, not guessed

Help ▸ Run Engine Diagnostics executes a 97-check regression suite against the live conversion engine — pitch math, dynamics, keyswitch placement and per-library transposes, verified by parsing the actual exported bytes.

Pairs with StringSync

Humanize your StringSync exports with ShredSync

ShredSync is a standalone humanizer that works with MIDI from any source — but it pairs perfectly with StringSync. Point its watch folder at your StringSync exports and every new tab is humanized automatically: player-style velocity and timing, kept inside each library's articulation bands so nothing ever mis-triggers. A perfect next step, never a requirement.
