Here you can define a chord that will sound when playing a single note. The chord is defined in terms of intervals. Currently 8 chords can be defined. You can also define a separation time, in seconds, so the chord plays as an apreggio. 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 arepeggiator is enabled then there are noteOffs between noteOns, i.e. With arpeggiator: noteOn, noteOff, noteOn, noteOff..., without arpeggiator: noteOn, noteOn, noteOff, noteOff.
If the arpeggiator is enabled, notes that are being played will be apreggiated. You can apreggiate chords you play if the preset is in String Mode or Poly Mode, or you can arpeggiated Mono Mode Intervals.
Speed of the apreggio, can be tied to Master Rate.
The Note Order determines which order the arpeggio will be played.
Octave indicates how many octaves the arpeggiator will play.
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
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 keys and where they are located.
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.
Many common 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.
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.
