Thank you for purchasing SESSION GUITARIST – STRUMMED ACOUSTIC 2, an acoustic guitar strumming sample library powered by KONTAKT. This document will provide you with instructions and advice on how to use the library, as well as some additional information.
We hope that you will be truly inspired by using SESSION GUITARIST – STRUMMED ACOUSTIC 2.
About SESSION GUITARIST – STRUMMED ACOUSTIC 2
SESSION GUITARIST – STRUMMED ACOUSTIC 2, or STRUMMED ACOUSTIC 2, as we will
call it in this manual, is a pattern-based guitar strumming library designed for ease of use in
musical productions. Its samples originate from two carefully selected vintage guitars, a smallbodied Martin O-17 mahogany 6-string guitar from 1934, and a Guild F-412 12-string built in
the 1960s. The Martin O-17 was recorded using a hand-picked vintage Gefell UM70 large diaphragm condenser microphone and a vintage Schoeps/Strässer cm060. The Guild F-412 was
recorded through a rare vintage Schoeps 221b small diaphragm condenser and an AEA R84
ribbon microphone. For the Martin O-17 6-string, the SPL GainStation 8 preamp’s tube stage
was utilized to create a little bit of edge, while the Guild F-412 12-string was recorded solely
through the solid state circuitry to achieve a cleaner sound. The signals were then converted by
the SPL Madison analog-to-digital converter, and fed into an RME MADIface XT via MADI.
Thanks to the quality and placement of microphones, superb room acoustics, and a high end
signal path, no additional signal processing was required to capture the unique character of
the instruments – only the AEA R84 ribbon mic used with the Guild F-412 got a little highfrequency boost to compensate for its darker sound. You will find that the STRUMMED
ACOUSTIC 2 sound sits perfectly in any mix and barely needs any additional processing like
EQ or compression.
The STRUMMED ACOUSTIC 2 library consists of two separate KONTAKT Instruments. The
Guild F-412 12-string guitar Instrument contains 51 patterns, while the Martin O-17 6-string
guitar Instrument contains 112 patterns. All of these patterns were performed live by professional studio guitarists Floryan Kœrber, Viktor Derksen and Andreas Dombert. The patterns are
grouped as "songs", each of which contains 6-8 patterns that go together well. You can select
patterns via keyswitches and play them as chords on your MIDI keyboard. Pattern playback will
always stay in sync with your host project. Regarding sound options, STRUMMED ACOUSTIC 2
offers stereo mode, true doubling mode, as well as the possibility to blend between a low and a
high voicing. With a selection of easy-to-use audio effects, you will immediately be able to
tweak the sound to your liking.
The key feature of STRUMMED ACOUSTIC 2 is its revolutionary playback engine. You can
seamlessly switch between different patterns, and also alter the dynamics in real-time, thus
creating true-to-life musical performances. In contrast to most pattern-based instruments, the
number of available chord types is virtually endless. Because all nuances of the original performance, such as exact timing and dynamics, are preserved, you will notice that the instrument feels very natural and organic. All of the integrated patterns can be played over a huge
tempo range in an outstanding sound quality.
Some of STRUMMED ACOUSTIC 2’s patterns, as indicated by a bass clef next to the pattern
name, allow you to play separate bass lines and slash chords: Simply play the desired chord
with your right hand, and add an independent bass note with your left hand to spice up your
playing for country, bluegrass, folk and more.
Document Conventions
This document uses particular formatting to point out special facts and to warn you of potential issues. The icons introducing the following notes let you see what kind of information can
be expected:
The speech bubble icon indicates a useful tip that may often help you to solve a task
more efficiently.
The exclamation mark icon highlights important information that is essential for the given context.
The red cross icon warns you of serious issues and potential risks that require your full
attention.
Furthermore, the following formatting is used:
▪ Text appearing in (drop-down) menus (such as Open…, Save as… etc.) in the software and
paths to locations on your hard disk or other storage devices is printed in italics.
The STRUMMED ACOUSTIC 2 instrument is designed to be played using a MIDI keyboard.
The patterns are triggered and selected by MIDI, allowing for fast arranging.
Patterns will automatically sync to the master, or host tempo. The patterns in this library can
be played at any tempo between ca. 60-65bpm and up to 180bpm and even above. Since
there is no time-stretching involved in the process, you will always hear the patterns in the
highest possible quality.
The patterns are based on actual recordings by a professional studio guitarist, so they
sound best in the typical tempo range preferred by most guitarists.
2.1Pattern Selection and Playback
Up to eight patterns can be assigned to chromatic keyswitches from C1 to G1 (this process is
described in section ↑3.2, The Pattern Browser). These keyswitches are displayed as red keys
in the KONTAKT on-screen keyboard. If no pattern is assigned to a slot, the corresponding key
will have no color.
The KONTAKT on-screen keyboard displaying the keyswitches for patterns (red), endings (yellow), pickups (green), and open
strings (orange). Chords can be played in the blue key range.
To select a pattern using your MIDI keyboard, press the corresponding keyswitch MIDI note.
To select a pattern via the user interface, click on the pattern you wish to use.
►
To play a pattern, play chords on your MIDI keyboard. If Latch mode is enabled (see chap-
►
ter ↑5, The Playback Page), playback will continue even if you release the keys.
To stop the playback, either trigger one of the five endings (see section Playing Endings
►
and Pickups) via keyswitch or, if Latch mode is disabled (see chapter ↑5, The Playback
Page), release the keys on your keyboard.
Because transition from one pattern/chord to another is always legato (without breaks), it is
best to make changes a little before the intended position, so that the engine is able to anticipate and add any requested effects (e.g. fret noise). The switch will occur seamlessly at the
nearest possible position. Find more information in chapter ↑6, Tips and Tricks.
If available, “Chase Events” should be enabled in your DAW settings; this will ensure
that the engine gets proper note information on sequencer start or cycle jumps.
2.2Playing Chords and Separate Bass Lines
STRUMMED ACOUSTIC 2 recognizes a great variety of chords, including major, minor, no
third, diminished, augmented, half-diminished, various suspensions, options and alterations,
and even some slash chords (e.g. G/C, Gmi/C, G7/C, Gmi7/C, Bb/C). You can also hold a chord
or a 5th interval with your left hand while playing a top note melody line with your right hand
and play separate bass lines with selected patterns. The instrument tries to play top lines, as
well as thirds and options in the very register you play them. This leads to an enormous number of available chords and voicings.
STRUMMED ACOUSTIC 2 provides a type of pattern specifically for bass lines, indicated by a
bass clef next to the pattern name. These patterns allow you to play bass lines with your left
hand independently of the chords played with your right hand.
A bass clef indicates the separate bass patterns.
There is no fixed split point that would divide the key range of your keyboard into a bass note
range and a chord range. Instead, while playing chords with your right hand, the light guide on
the KOMPLETE KONTROL keyboard dynamically highlights the range of keys available for
playing a separate bass note in violet.
If you play a separate bass pattern with your right hand only, an appropriate bass note is added
automatically, usually the chord's root note. Some of these patterns also create an alternating
bass, e.g. the bass note alternates between the root note and the fifth above.
Now, as soon as you add a separate bass note with your left hand, the pattern will seamlessly
transition from the automatically generated bass to the bass note pressed on the keyboard.
By playing a separate bass note, you can create all inversions of triads and seventh
chords. You can even play chromatic bass lines with your left hand to accompany those
chords as you hold them in your right hand.
The separate bass patterns do not like overlapping bass notes, because an overlap would
technically mean that two different bass notes exist at the same time. An easy way to
avoid those overlaps is to play the bass notes with only one finger. If you prefer to use
more fingers of your left hand to play bass lines, make sure the notes you play do not
overlap.
In addition to the actual patterns, STRUMMED ACOUSTIC 2 provides a variety of endings as
well as pickup sounds and additional palm hits on the corpus/strings of the guitar. The corresponding sets of keys are marked yellow and green on the KONTAKT on-screen keyboard.
To trigger an ending with the current chord, play any of the five keyswitches from G#1 up to
►
C2 with the intended intensity (i.e. velocity). These ending keys are marked yellow in
KONTAKT's on-screen keyboard. When an ending is played back, the current pattern
playback will be stopped.
To trigger an ending with a different chord, hit the new chord just before triggering the de-
►
sired ending keyswitch. As a result, only the ending chord will be played back with the
new chord.
To play a pickup sound, play any of the two keyswitches C#2 or D2, marked as green keys,
►
with the intended intensity (i.e. velocity).
Only the volume of Pickups and Endings can be altered via input velocity. To alter the
dynamics of patterns, use the Pitch Wheel (see section ↑2.5, Controlling the Accents of
Patterns).
Use the Open String Key to Create Transitions
To make transitions between chords sound more natural, use the Open String feature. The orange D# key just below the blue area of the keyboard contains the sound of a guitarist playing
open strings (E-A-D-G-B-E). Hit the Open String key slightly before triggering a new chord. This
will replace the last strum before the chord change with the typical sound of strings briefly being released by the guitarist's left hand before they get pressed down again for the next chord.
For example: The guitarist plays A minor, takes the fingers off the fretboard and repositions
them to play, let's say, F major. While his left hand performs the chord change, his right hand
keeps strumming in time, eventually hitting the strings while no chord is pressed. This results
in a typical "first chord to open string strum to next chord" transition.
