Load an instrument and play, no need to load six instances
to cope with pitchbend for each string. Gtak detects the pitchbend
information that the Guitar to MIDI converter generates when you
play bends, hammer ons, pull offs and slides and applies it to
the correct notes.

Up to 64 instruments can be placed in the Kontakt rack, each instrument
has its own copy of Gtak. You can select the strings and the
range of frets that play each instrument. With the Axon you can
also select which picking positions play each instrument.

All 1079 instruments from the Kontakt library are supplied with Gtak
already inserted in each one. Each instrument has been set up with
appropriate values for pitchbend quantisation mode. For copyright
reasons we do not supply the library's samples, these are installed
when you install Kontakt 3.
Built in pedal control allows you to control which instrument plays
using an MIDI foot pedal (or the built in pedal of your guitar to MIDI
converter). There are hold and sustain foot pedal modes allowing you
to set one instrument playing while you solo over the top. Kontakt's
pads, arpeggiators and drum machines give endless possibilities.
Gtak can emulate most of pedal modes provided by Guitar to MIDI
converters. You can choose whether the action is take when the
pedal is up or when it is down, assuming "when up" is selected:
| Pedal Mode | Pedal Down | Pedal Up |
| Hold | Plays normally | Sustains all
exisiting notes, no new notes sound. |
| Sustain | Plays normally | Sustains
notes, new notes sound. |
| Hold+Sustain | Holds | Sustains |
| Mute | Plays normally | No notes are sounded. |
The instrument can also be muted by a range of CCs. This allows
you to have multiple solo and backing instruments with only one
responding to the guitar at a time.
Gtak handles pitchbend quantisation for each instrument. Pitchbend
can be left unquantised, quantised to semitone values, or quantised
automatically when more than one note is playing so chords sound in
tune. You can also set it so pitchbend triggers a new note rather than
bending the existing note.
We have adjusted the transpose value in each instrument so that
the guitar can play as many notes as possible. Umpa away!
Kontakt's sampled acoustic instruments play over the same range as
the real instruments. This is great if you are a boffin trying to
program a realistic violin part, but annoying if you are just trying
to play.
To get round this problem we have extended the range of all
instruments to match the guitar. For instance, the violin show above
originally only played down to G, by changing the range the lowest
sample we have made it play down to E. A small loss of realism for a
big gain in playability!
Gtak's smart controller routing lets you control the instrument you
are playing. For instance if you have the volume control on your pickup
set to send MIDI volume (CC7) then it will control to volume of the
instrument you played last. All other instruments that did not play
because they were assigned to different strings, held or muted with
the pedal etc. will not be affected.
This also works with Kontakt's extensive automation capabilities.
Almost everything can be controlled.
The VSL legato instruments are very special, for each normal
sample there are 24 extra samples, each played legato starting from a
different note (from 12 semitones below to 12 semitones above).
The standard VSL legato script was written for keyboard players,
who can only play legato by playing single notes and overlapping
the starts and ends. This limits legato playing to playing one
note at a time.
Guitarists play legato using hammers, slides and bends -
sometimes on more than one string. Gtak harnesses this power by
detecting legato playing, triggering a new note, and telling the
custom 'Gtak Legato script' to trigger one of the special legato
samples. This means you can play legato chords.
The Kontakt 3 library has 5 of these special legato instruments:
- Violin ensemble (legato)
- Cello ensemble (legato)
- Viola ensemble (legato)
- Flute (legato)
- French Horn ensemble (legato)
Try them, they're addictive!
Instruments that use keyswitching have been mapped so that the
low E string controls the key switch. For instance with the VSL String
Instruments (like the Violin above) the different playing styles can
be choosen by playing the folloing notes on the low E string:
| Playing low E... | Switches to... |
| Fret 1 | staccato 1 |
| Fret 2 | staccato 2 |
| Fret 3 | sustain |
| Fret 4 | tromelo |
| Fret 5 | sforzando |
| Fret 6 | fortepiano |
| Fret 7 | pizzicato |
Kontakt's Groovebox and Drum Computer give you a built in 6 channel,
12 pattern drum sequencer in drum kit instruments. Gtak sets
the low E string so playing a note on frets 1 to 12 triggers
pattern 1 to 12, playing the open string stops playback. Play
the provided patterns, or program your own!
In the Urban Beats collection the Master FX section gives you 12 FX
presets - radically alterring the sound through filters, delays and
other effects. Gtak is set so playing notes on the A string changes
the preset.
The Gtak script can also be loaded into other instruments that you
buy or create yourself. It's as easy as one, two, three, um, four:
- Open the Instrument's editor.
- Open the Script Editor.
- Select the first script slot.
- Choose Gtak from the user preset menu.
Note: because of various strange things in the KSP scripting system
we can not guarantee that Gtak will work if an instrument uses other
scripts.
The Config panel lets you customise Gtak:
- If you are using a non-standard tuning you can set the open
string note for each string here
- You can set a transpose value for each string and a transpose
value for the whole instrument, so that the notes you play trigger the
notes you want.
- Set the velocity of notes triggered when pitchbend is set to
trigger new notes (relative to the velocity of the original note).
- In pedal sustain modes choose between sustaining one note per string
or all notes played.
- Set various settings such as base channel, number of strings and
pitchbend range to match your Guitar to midi converter.
- Set how incomming MIDI controller data is passed to the Kontakt
Instrument.
The Transpose menu in the Config panel lets you load and save
presets for all six string's transpose values.
