§ Playing guitar on a keyboard
has never been easier §

Creating a realistic guitar track from samples is a tough job. Guitar players voice chords differently, strumming is not easily reproduced on a keyboard, and guitar players use all sort of techniques such as palm muting, scratching and sliding simply not available on a keyboard. Strum GS-2 now does all of this for you!

Strum with MIDI loops

Use the vast collection of recorded strumming patterns over the chords you play and find inspiration for your track. Drag and drop the loop to your host sequencer and make it perfect for you song.

The right voicings for the chords you know

Strum GS-2 chord library contains basic and extended chords available in open, movable, or drop voicings. Play the chords you know and Strum voices them automatically as a guitarist would.

Strum on your keyboard

Trigger down and upstrokes, scratches and mutes, or create picking patterns using the arpeggio keys.

Articulation and expression

Slide and bend with the pitch wheel or aftertouch. Add vibrato with the modulation wheel. Natural hammer-ons and pull-offs when playing leads.

§ Guitar craftsmanship §

Have you ever had the chance to create your own guitar? Strum GS-2 allows you to do just that by controlling every aspect in the making of your instrument.

Picks and fingers

Hand picking or playing an heavy riff? Use a pick that is rounded or sharp, stiff or soft. Dig into the strings or use a light touch, play near the bridge or towards the neck for an evolving tone.

String by string

Select material and natural decay for each string. Precise control of coupling and interactions at the bridge breath life into your tone with beating and organic envelopes.


Whether they are single coils or humbuckers, pickups are a fundamental part of the electric guitar sound. They shape the whole instrument’s response and their multiple configurations give tremendous tone flexibility.

Body shopping

The soundboard of a guitar radiates vibrations from the strings. Choose a body size to colour the sound with specific resonances and find the right character.

Mutes and scratches

As on a real guitar, strings interact with the players hands and frets. Fine tune your rhythm parts and rifs with palm muting, scratches, and hammer-ons.

§ Bare naked—All suited up §

You’ll love the pure raw sound of Strum GS-2, but the built-in effects will bring it to so many places that you’ll enjoy having them on hand.

And you have a chock-full of them to choose from: compressor, equalizer, delay, distortion, phaser, chorus, flanger, wah wah and notch filters, and reverb.

§ Buzzing Around §

The community has good things to say about Strum…

  • Oustrip any sample-based guitar plug-in

    AAS Strum GS-2 is the most faithful reproduction of any acoustic guitar you can put on your computer desktop.

    Its performance features and the sound quality of its physical modeling far outstrip any sample-based guitar plug-in.

    Marty Cutler, Keyboard
  • Extremely expressive—5/6

    Strum presents itself as an extremely expressive and playable instrument.

    Our test revealed very favorably the full sound and dynamic response of Strum.

    What's exremely impressive is the multitude of chords the program recognize.

    Mario Schumacher, Beat
  • Remarkably realistic

    The modelled sound is remarkably realistic, and with care and practice fairly convincing strummed and arpeggiated rhythm parts can be achieved, as well as expressive solo lines.

    Strum is entertaining and great fun to use, and a valid alternative to sample-based guitar emulations.

  • Utterly convincing—4/5

    Strum’s models are as good as it gets, and its accurate articulation and sophisticated chord voicing make it an utterly convincing chord-melody instrument, an excellent solo voice, and an agile accompanist. I recommend it highly.

    Marty Cutler, Electronic Musician
