Performance Settings


Config

Play Mode

The Play Mode selects how the keys of the playing surface are mapped to the Guitar strings: In addition, there are two modifiers that can be applied to the Play Mode:

Quantization (Pitch Rounding Modes)

Pitch Rounding, or Quantization, allows playing in tune without having to touch the exact horizontal-center of each key. There are several settings related to this in the Quantization pane under Config:

Mono Mode Intervals

Here you can define a list of intervals that will sound when playing a single note. This is called a Mono Mode Interval or an MMI. Currently 8 MMIs can be defined for each preset. You can also define a separation time, in seconds, so the chord plays as an arpeggio. The separation time can also be set from Arpeggiator or Master Rate. If you enable the Arpeggiator, the separation time controls will become unavailable. If you select use Master Rate however, the separation time derived from the Master Rate will stick.

Note: If Mono Mode Intervals are enabled without the arpeggiator then there are no noteOffs between noteOns. If the arpeggiator is enabled then there are noteOffs between noteOns, i.e. With arpeggiator: noteOn, noteOff, noteOn, noteOff..., without arpeggiator: noteOn, noteOn, noteOff, noteOff.


Arpeggiator

If the arpeggiator is enabled, notes that are being played will be arpeggiated. You can arpeggiate chords you play if the preset is in String Mode or Poly Mode, or you can arpeggiated Mono Mode Intervals.

Tempo

Speed of the arpeggio, can be tied to Master Rate.

Note Order

The Note Order determines which order the arpeggio will be played.

Octave

Octave indicates how many octaves the arpeggiator will play.

Other Controls

Enable

Enable the arpeggiator

Latch

Latch the arpeggio on Note On. The arpeggio will not stop with Note Off, and will be reset with a new Note On

Reset On Note On

Reset the Mono Mode Interval on Note On


Control

Master Rate

System-wide Master Rate. Master rate can be taken from MIDI Clock, tapped out or specified in terms of bpm, Hz or seconds. Certain parameters on given effects, such as Echo delay, can subscribe to Master Rate, and also specify a multiplier. Anywhere you see a Master Rate button this can be done

Preset's MIDI Configuration

MIDI Configuration used by the current GeoShred Preset, overrides the default MIDI configuration

Preset's MIDI direction

Sets the MIDI direction of a preset to In or Out

Finger Expression

Finger Expression provides a way to either take input from the Expression Pad Y axis or Key Y/Key Z, or both.

If Enable is turned off and Finger Expr is turned off or on then there is no effect.

If Enable is turned on and Finger Expr is turned on then parameters assigned to the Expression Pad Y direction are NOT sent when finger is moved on the Expression Pad. Parameters assigned to Poly Expression ARE sent when a finger is moved up and down a key, (Key Y) or pushed into a key if Key Z is used.

If Enable is turned on and Finger Expr is turned off, then it's the reverse, the Expression Pad Y direction are NOT sent and Poly Expression ARE sent.

Debugging tip: Turn on Parameter Trace in the Trace Window to verify what you are hearing


Keyboard

Layout

Number of Strings is the number of rows on the playing surface.

Number of Frets is the number of columns on the playing surface.

Width and Pan can be used to modify the width of the keys, and their horizontal translation.

Diatonic changes the keyboard from Chromatic (all notes) to a Diatonic Keyboard (only notes in the current scale).

Scale/Root

A variety of scales can be chosen if you like. You can just keep the scale as major and the root as C and note where the accidentals are, or you can adjust the scale and root if you like.

Tuning

Many common open-string tunings are available. The most popular are Standard Guitar and Geo Shred All Fourths. Here you also specify the max and min octave for the preset. Most of the time you want to allow the maximum range, which is -1 to 5.


Performance Settings for the Control Surface

Scrape

The effect of Scrape parameter is repeated excitation of the strings that are being played.

The faster you move your finger, the louder the scraped notes will be, with the maximum velocity being 1.0

The value of the Scrape parameter is not settable from Performance Settings, but it is a parameter you can choose when you make Control Surface, Expression Pad or Key Y mapping.

You can turn on Note Update trace to see the effect your choice of scrape has

You may want to pick different scaling factors for Key Y scrape mappings than you do for the Expression Pad or Control Surface sliders, because the keys are often physically smaller.

Play Track

Play a backing track. Play always rewinds

Madhyama Tuning

Indian Music is usually sung in the range of Lower Octave Pa through higher Octave Pa. Tanpura tuning "Pa, High-Sa, High-Sa, Low-Sa (5,8,8,1)", also called "Pa-Shruthi", is ideal for this range and provides rich resonating harmonics for the background. However, in some ragas the highest note in the scale may be limited to P or D* or N*, and may not even go to Higher Sa. For these ragas, performers treat Ma as the Sa, thereby shifting the center of singing to become aligned with the center of the Raga scale. This makes the raga sound much more pleasant, full and beautiful.

This is referred to as using the Madhyama Shruthi or "Ma Shruthi". It is enabled by the GeoShred Madhyama Tuning Panel, where one can choose the Ma-Low or Ma-High settings. GeoShred does all the adjustments to the Drone and also to Swaras on Glass, in sync, making the madhya tuning performance easier and authentic. Note, if the raga does not have a Pa in its scale, it is important to set the drone Pattern to "M1, High-Sa, High-Sa, Sa (4,8,8,1) ", to remove Pa from the drone. It does not become Madhyama Shruthi, and does not require the use of the Madhyama Tuning Panel, unless Ma is actually used as Sa.

MIDI Out
