Creating an Arpeggio on the Roland GR-30
The Roland GR-30 Guitar Synthesizer is a powerful vintage guitar synth. It includes 384 brand new Tones, 256 Patches, and spatial effects including reverb, chorus and delay.

In addition, there are some unique features such as the world's first synth Harmonist and guitar synth Arpeggiator. The purpose of this document is to provide a "hands on" guide for programming the Arpeggiator.

First, we will select the Tones (sounds) that will be used.

Second, we will assign the Tones to specific strings using the Tone Mix and String Select procedures.

Third, we will program the arpeggio parameters such as Arpeggio Tone, Arpeggio Rhythm, Arpeggio Value, and Arpeggio Tempo.

Finally, we will create an arpeggio using Real Time and Step Write methods and store the arpeggio patterns into the GR-30's internal memory. For the purpose of this document, we will create an arpeggio for a nylon-string guitar sound that is layered with a string pad sound on all strings.

The arpeggio will not affect the string pad sound. The concepts and procedures that we will use to create this arpeggio can be applied when creating your own arpeggios.

1. Selecting Tones
Tones are the basic unit of sound in the GR-30. Tones can be combined with other parameters such as brightness and attack to create a Patch. The GR-30 allows you to combine up to two Tones per Patch. Use the following procedure to select Tones:

1) Use the [+] / [-] buttons to select Patch A52. This Patch uses two Tones - "NYLON GUITAR SW" and "SLOW STRING."
2) Use the EDIT TARGET dial to select "1st TONE."
3) Use the PARAMETER SELECT dial to select "[A]" (TONE #).
4) Press EDIT/PLAY. The currently assigned Tone number will be displayed.
5) Use the [+] / [-] buttons to select Tone #51 (if necessary).
6) Use the EDIT TARGET dial to select "2nd TONE."
7) Use the [+] / [-] buttons to select Tone #293 (if necessary).
8) Use the PARAMETER SELECT dial to select "WRITE PATCH?" and press the [+] and [-] buttons simultaneously to store these settings into memory.

II. Tone Mix and String Select
Once you've selected your Tones, you can adjust the balance between the two Tones. When both Tones of a Patch are assigned to all six strings, the Patch is called a "Layered Patch." When the two Tones of a Patch are assigned to different strings, the Patch is called a "Split Patch." However, because each string can have one or both Tones assigned to it, Patches can be configured as a combination Split and Layered Patch. Use the following procedure to adjust the Tone mix and String Select for this Layered Patch:
1) Use the EDIT TARGET dial to select "TONE MIX."
2) Use the PARAMETER SELECT dial to select "[A]" (LAYER).
3) Press EDIT/PLAY.
4) Use the STRING SELECT dial to select "ALL."
5) Use the [+] / [-] buttons to select "A-b" (if necessary). This assigns both Tones to all six strings.
6) Use the PARAMETER SELECT dial to select "[D]" (1:2 BALANCE) and use the + / - buttons to select "25" (if necessary). This adjusts the BALANCE between the two Tones.
7) Use the PARAMETER SELECT dial to select "WRITE PATCH?" and press the [+] and [-] buttons simultaneously to store these settings into memory.
