A-List Acoustic Guitarist
Introduction
Acoustic Guitarist is the first Rack Extension instrument in the A-List series for Propellerhead Reason and Reason
Essentials. Think of Acoustic Guitarist as a professional session guitarist playing rhythm guitar on a top-notch
acoustic steel string guitar, and performing exactly as you wish, while leaving you full control over sound character,
musical performance and mix. Whether you want to add realistic rhythm guitar tracks to your productions, use it as an
inspiration for writing songs on a train or plane, or as source material for creative sound design - it will get you from
idea to result as fast as possible.
At the core of Acoustic Guitarist - and all future instrument of the Propellerhead A-List series - is the idea that you
can create professional sounding instrument tracks exactly the way you would get them from an A-List player in the
studio. There, you'd give them a lead sheet, adjust sound character and mix, and tell your session guitarist what kind
of musical style and performance you're expecting, and a great player would deliver exactly that.
Acoustic Guitarist does exactly that for you: the lead sheet becomes MIDI notes in your Reason tracks (or played live
on a MIDI controller), there are controls for sound and mix, you load styles and select phrases in real-time, and there
are performance controls to vary the performance.
Whatever Acoustic Guitarist does, it does extremely well, fast, and asking absolute minimal effort of you.
Try it now - it's easy and fun!
Acoustic Guitarist is designed for creating stunning dynamic performances using very simple MIDI commands. The
perfectly played phrases and styles all come built in. All you need to do is provide chords, pick phrases and optionally
make (real-time) adjustments. You can even dynamically control palm muting of the strings for dynamic expression
and creation of your own phrasings.
Here's how it basically works - and we encourage you to try it now.
1. Create an Acoustic Guitarist device in the rack.
It will load a default style that's all you need for now.
2. Start playing on your connected MIDI keyboard.
D
4
Hit a key or chord from the note C4 and upwards and Acoustic Guitarist will start playing.
A-LIST ACOUSTIC GUITARIST
D
Activate the Latch switch so it keeps playing.
D
Hit the note B3 when you want to stop in Latch Mode.
D
Move the Mod Wheel or apply Aftertouch on your MIDI keyboard.
You can live-control palm muting using the Mod Wheel or Aftertouch. Turning up the Mod Wheel gradually
increases the pressure of the palm, Aftertouch switches between no and full pressure.
D
Vary the phrasing.
Pressing keys (or generally: sending MIDI notes) between C1 and Bb3 selects phrases. The lower two octaves
select a set of standard phrases, the C3-Bb3 octave selects phrases of the currently loaded style.
D
Change the sound character.
Use the mic/pickup switch and the Character control to vary the overall tone of the guitar.
D
Add a second guitar player
Activate the Doubling button in the performance section to activate a second player (similar to overdubbing in the
studio), with the players panned left and right in the stereo image.
Background
It is important to know that Acoustic Guitarist does not emulate a guitar. It does not let you edit individual notes, but
it also does not require you to play individual notes, or to think about how to emulate realistic strumming or typical
guitar voicings. It has all that built in, simply because it is based on actual rhythm guitar recordings, not samples of
individual notes.
What Acoustic Guitarist emulates is therefore a studio guitarist who already knows how to play. Because when you
have an idea in your head and want to get it to "tape" the last thing you want to do is having to struggle with MIDI
editing and trying to make a MIDI performance sound realistic. What you need is a professional player recording your
idea the way you want it. That's exactly what Acoustic Guitarist does.
The foundation of Acoustic Guitarist is real performances on a top-notch acoustic guitar, played by a professional
player and recorded both with a studio microphone and a pickup mounted on the guitar.
During the sessions for Acoustic Guitarist, about 1100 phrases were played and recorded, totaling more than 15
hours of guitar performances. Those were then meticulously selected, adjusted and prepared in a sophisticated and
unique way, allowing us to create a Rack Extension that can virtually play any guitar phrase at any tempo and always
sound like an original performance.

Panel controls
Guitar section
In this section you set the basic sound character of the Guitar.
Character
The Character knob adjusts the recorded signal before it enters any further sound processing inside Acoustic
Guitarist. It offers five distinct settings:
Knob position
Character
Use...
Warm
Bassy tone with softened high end.
... to beef up an arrangement in the low/mid range. Works best with slow, not too
animated material.
Full
Pronounced mid range, low and high
end attenuated.
... for adding harmonic content to a mix without adding too much high end
(strumming)
Original
Untreated signal, straight from the
microphone/pickup.
... for a straight acoustic guitar character, or if you plan to do all sonic treatment in
the mixer or using studio processors.
Bright
Pronounced high mids and treble, low
end rolled off.
... for a guitar track that blends well with other harmonic/chord tracks, without
interfering with the lower mids. Allows you to bring down the level and still keep
the strumming "recognizable".
Crisp
High frequencies of the strum noise
almost isolated, no bass or mids.
... add high end animation to any mix, without interfering with other chord sounds.
Works particularly well with doubling activated.
Type
Acoustic Guitarist lets you choose between two signals:
• Mic
A vintage large-membrane studio condenser microphone positioned about 1 ft. from the neck/bridge intersection.
The Mic signal has strong bass and treble and generally a more "rounded" sound character.
• Pickup
A pickup mounted on the guitar. The pickup sounds drier, more compact and direct.
!
Switching between the two Types (Mic and Pickup) replaces entire sample sets. This means it will take a couple of seconds before the new samples are loaded.
q
Some engineers like to combine a guitar recorded via pickup with one recorded via microphone. Combine two
instances of Acoustic Guitarist to accomplish this.

Performance section
This section is a mixture of selectors, knobs and displays for selecting, adjusting and monitoring the musical
performance.
Key
This control sets a key for the song, forcing all chord input to the most useful chords in the selected key.
• In the Off (-) position, all chords in all keys are available:

• In any other position (C, C#, D, Eb etc.), only the chords matching the set scale are available (see below).
Using the Key parameter has two potential benefits:
• It's a handy helper if your keyboard or musical skills are basic, or if you want to simplify chord input in general,
as it will "quantize" all chord input to chords that aren't entirely wrong for the given key.
• It saves memory, because it unloads all chords that aren't in the currently selected key.
When a key is set, these are the chords Acoustic Guitarist will play depending on the actual input - shown in C:

The currently played back chord is always displayed in the Chord display (see below).
Chord
This is not a control, but displays the recognized chord. Acoustic Guitarist recognizes and plays 13 chords. More on
chords and how to make best use of them in “Chord Sets and Fingerings”.
Styles and Phrases
Acoustic Guitarist is designed to produce rhythm guitar tracks. As the term indicates, a rhythm guitarist doesn't play
melodies, but phrases. A phrase in this context is a rhythmic sequence of strummed chords.
A style in Acoustic Guitarist is a collection of phrases of a certain musical context. Styles are given descriptive names.
Phrases, although, are not named but numbered.
!
8
From left to right, phrases become more intense - i.e. denser and more animated. You can add to the dynamic
expression of a song by selecting phrases accordingly: As you move from intro to verse to chorus, move right
on the phrase selection keys and vice versa.
A-LIST ACOUSTIC GUITARIST
Style
In this menu, you can select one of the 26 included musical styles, each available in a normal and half-speed version.
Each style features 11 individual phrases (see “Phrase”).
Phrase
This readout displays the phrase currently selected by incoming MIDI note information (see “MIDI keyboard layout”
below for details).
Swing
This knob gradually applies a shuffle feel to the guitar performance by delaying the offbeats.
Depending on the selected style, 8th or 16th note offbeats will be affected. At maximum position, the off beat will
have the same timing as the last note of a triplet.
Not all phrases contain 8th or 16th note offbeats so in these cases the Swing control has no effect.
Feel
With this control you can tell the virtual player to push or play laid back, i.e. it affects the overall timing of the guitar
performance. Right from center, offbeats will be slightly advanced (Push), left from center they will be delayed (Pull).
Latch
Use this toggle button to determine if Acoustic Guitarist should always keep playing or only when keys are held.
If on, Acoustic Guitarist will keep playing after a chord is pressed, until either Latch is switched off or the Stop button
in the Reason/Reason Essentials sequencer is pressed.
A sustain pedal can be used as a temporary latch (but does not affect the appearance of the Latch switch). Lifting
the sustain pedal unlatches any notes that are no longer held, even if the Latch switch is still on, see “Sustain Pedal”.
Doubling
Use this function to create the impression of two independent players playing at the same time.
When on, Acoustic Guitarist will add a second guitar player to the currently selected signal and places them at
opposite stereo positions.
Mix section
With the two controls in this section you can adjust the transients and volume of the output signal.

Attack
When turned left, this control softens the attack transient (strum) of the guitar signal and accentuates the sustained
portion. When turned right, it makes the attack more pronounced.
Volume
Adjusts the audio output volume of Acoustic Guitarist for maintaining an optimal input level into the mixer or
subsequent audio processors.

The MIDI keyboard layout for Acoustic Guitarist.
• The MIDI keyboard (or - for that matter - any controller that can send MIDI notes) gives you extensive musical
real-time control over Acoustic Guitarist.
• With MIDI Notes, you start and stop the performance, you determine the chord that's played, and by selecting
phrases you can vary the musical performance.
• The layout has been designed so even if you have only a 2-octave keyboard, you can control Acoustic Guitarist
in a useful way, particularly when using the octave transpose button that most keyboards offer.
• With a 5-octave keyboard you have full access to as many as 23 standard phrases (always available), 11 styledependent phrases, a "silent phrase" and a stop function.
• Phrases are sorted from simple/left to complex/right, so as you play up the keyboard, the phrases become
denser and more animated.
MIDI Note
Function
C1
Select "Silent" phrase. This is useful for creating gaps in other phrases without losing the
phrase position, and in combination with Gate/CV triggering.
C#1 to B2
Select standard phrases - this set is always available, independent of the chosen style.
C3 to A#3
Select 11 different phrases in the current style.
B3
Stop Phrase.
C4 and above
Chord Input.
Building Custom Phrases
The CV/Gate input on the rear panel of Acoustic Guitarist interprets notes differently than the MIDI Input. Notes from
C#1 to C#5 don't select phrases and chords, but individual slices of which are laid out across the note range.
You can use this feature to create your own phrases by triggering "slices" (which are individual strums extracted from
the original performance). Try it with a Matrix pattern sequencer!

Note that this just replaces the phrase selection - you will still need to send chord notes via MIDI Input to get
the guitarist strumming away!

Chord Sets and Fingerings
Chord Sets
Chords take up memory in RAM, therefore Acoustic Guitarist loads only five chord types by default, although it
supports 13 different chords.

To load the Full Chord set, press Tab to get to the rear panel view of Acoustic Guitarist, and set the Chord Set
switch to Full.
The following selection of chords for the two chord sets is also printed on the rear panel of Acoustic Guitarist:
Default Chord Set:
maj, min, 7, min7, maj7, sus4
Full Chord Set:
maj, min, 7, min7, maj7, sus4
-5, +5, 6, min6, min7-5, sus2, dim

MIDI Controllers
Pitch Bend
The Pitch Bend wheel can be used for creating bending or vibrato. The pitch range is fixed at ±2 semitones.
Mod Wheel
Palm Muting is a powerful method for live-controlling the phrasing of Acoustic Guitarist.
• The Mod Wheel controls the Palm Muting that your guitarist applies to the performance.
In the Mod Wheel's default position, no Palm Muting is applied. The further you turn it up, the shorter the notes will
become. The maximum position of the Mod Wheel produces entirely "tone-less" muted strums.
q
You can add Palm Muting after the fact by adding a lane to your Acoustic Guitarist track and recording a Mod
Wheel performance on top of your notes. Experiment with multiple tracks with different Mod Wheel
performances for greatly enhanced live feel and two-player impressions.
Aftertouch
Like the Mod Wheel, Aftertouch lets you control Palm Muting, but works like a switch between "no muting" and "full
muting".
Expression
The Expression Controller is applied individually to each strum in a phrase, so the volume of the previous step that is
still playing is not affected. This can be useful for fine-tuning performances.
!
Note that velocity is not used to control volume, as it is difficult to play all notes of a chord with consistent velocity.
Sustain Pedal
The Sustain Pedal replicates the “Latch” button, so you can use it as an additional way of varying phrases in real-time.
Pressing the Sustain Pedal activates latching of chord notes. Releasing the Sustain Pedal releases any latched chord
notes even if the Latch button is on.

Connections
!
Remember that CV connections are NOT stored in the Acoustic Guitarist patches! If you want to store CV connections between devices, put them in a Combinator device and save the Combi patch.
CV Input
The Note and Gate CV inputs can be used for adding extra phrase creation options by using the CV output from
another CV/Gate device (typically a Matrix or an RPG-8). Note that the Gate input also responds to keyboard
velocity. Please refer to “Building Custom Phrases” above.
Output
On the right are the main audio outputs. When you create a new Acoustic Guitarist device, these outputs are autorouted to the first available channel in the Reason/Reason Essentials main mixer.

Advanced tips
Optimizing chord recognition
Acoustic Guitarist tries to be as tolerant to sloppy chord input as technically possible, but particularly when liverecording to a MIDI track, you may end up with it not playing the chords you had in mind. It's really easy to fix this
situation if you keep a few things in mind:
D
Always quantize your MIDI notes in the sequencer.
Notes with different starting positions can lead to multiple chords getting recognized one after another, or cut-off
chords.
D
Clean up note lengths to make sure there are no note gaps or overlaps.
In the Legato Adjustments section of Reasons' Tool Window you can force legato and remove overlaps.
Minimizing memory consumption
Acoustic Guitarist is pretty light on RAM for what it does, but of course memory consumption can add up if you use
multiple instances.
How much memory Acoustic Guitarist requires entirely depends on the settings of the Chord Set and the Key
parameter loaded:
• The Default Chord Set requires about 210 MB of RAM.
• The Full Chord Set increases this figure to around 440 MB.
• When setting a key, the allowed chords are all in the Default Chord Set, so if you have the Full Set selected,
you can save memory by switching back to the Default Set on the rear panel of Acoustic Guitarist.
