SHREDSYNC 3Guitar Pro & MIDI Guitar Humanizer

ShredSync 3 turns a Guitar Pro tab or a MIDI file into a real guitar or bass performance. It moves every stroke a little off the grid the way hands do, strums chords in the picking direction, lets the timing push and pull over a phrase and lets the picking strength breathe, while palm mutes, pinches and your library's keyswitches stay exactly as written. Your own guitar library plays the result inside the app, and you drag the MIDI straight onto a track in your DAW.

Both work. A Guitar Pro file says how every note is played, so ShredSync 3 writes palm mutes, harmonics, slides, hammer-ons, bends, dead notes and dynamics for your library and then humanizes them. A MIDI file says which note and when: ShredSync 3 humanizes it and keeps your own keyswitches and velocities. Have both? Use the Guitar Pro file.

No. ShredSync 3 is an app next to your DAW, on purpose: a player's timing depends on the notes that come next, so it works on the whole part. Drop a file in, humanize it, then drag the MIDI onto a track or save it. To humanize a part from your song, drag the clip out of your DAW into ShredSync 3 and drag the result back.

Popular guitar and bass libraries are mapped out of the box: The Odin III, Odin x Ari and The Behemoth, Shreddage 3.5 Argent, Hydra and Jupiter, AXURE II, Ample Metal Eclipse, Hellrazer and R, Ample Guitar L, Ample Bass P / J, RealEight, Djinn Bass 2, Grove Bass, Umansky Bass and EZbass. Load your library and ShredSync 3 picks its map by itself; for Kontakt and other samplers it asks once which library runs in them and remembers it. Any other instrument plays with the generic guitar or bass map, or with a map you make yourself.

To hear the real sound, yes: ShredSync 3 loads the guitar or bass library you already use in your DAW and plays the preview with it, with its own keyswitches and sounds. Without one, a built-in guitar voice plays, which is enough to judge the timing. The MIDI you save is played later by whatever instrument you use in your DAW.

Yes. The library you choose in Sound plays every track, and any track can load its own instrument, so rhythm guitars, lead and bass each play with the right library. A simple mixer sets the volume and pan of each track for listening. If your library plays a clean DI sound, the built-in Quick Amp gives it a Rhythm or Clean amp tone, or you load your own amp sim.

ShredSync 3 keeps going. Every library runs on its own, so if one crashes or freezes, only that track goes quiet, the rest keeps playing, your settings stay, and it restarts with one click.

Yes. Double L/R writes two performances of the same part and Quad writes four: they share part of their feel like one player recording the part again, so hard-panned rhythm guitars sound like real double takes. Drag MIDI drags all of them.

Log in with the account you bought it with and your upgrade price comes off at checkout automatically, no code needed. Own the ShredSync + StringSync bundle, or both apps: ShredSync 3 is free. Own one of the two: you pay only the difference between its price and ShredSync 3.

StringSync is now part of ShredSync 3. It opens Guitar Pro 3 to 8 files, writes them for your library with every technique under your control and humanizes the result, or gives you the exact conversion with humanizing switched off.
