Scale Overview

In order to quickly notice if any keys have an individual tuning (as controlled by the Scale

Group Oset parameters), the Scale Group provides an Overview, showing if active (non-

zero) oset parameters are present.

→ Panel Unit

The active state is indicated by a high-

lighted bar for the Scale Group in the

selection stack, and when the Scale Group

is selected, a “Reset” option is provided

by So Button 1, which will set all active

Oset parameters to zero.

→ Graphical UI

The active state is indicated by an exclama-

tion mark in the Scale Group header, and

a “Reset” option is provided by the header

context menu, which will set all active

Oset parameters to zero.

4.9 The Undo Mechanism

Simple Undo/Redo

The current, active branch can be navi-

gated by using the Undo and Redo buttons

in the Edit Panel, recalling the correspond-

ing state immediately.

When the Undo button was pressed, an

Undo indicator will appear in the Preset

screen, showing that the Redo option is

available. The Parameter screen also shows

the Undo indicator, as long as no other

parameter is selected.

Signal Flow Overview (Panel Unit only)

When selecting a parameter of a particular group, blinking LEDs on the Panel Unit show

where the output signal of this group is applied further in the signal chain. (If, for example,

a parameter of the Feedback Mixer is selected, the PM FB and FB Mix parameters of the

Oscillators and Shapers will have blinking LEDs, if they are unequal to zero - indicating

that the output signal of the Feedback Mixer is applied in these particular sections.

߰ The Signal Flow indicator is optional and can be disabled in the Setup Menu (see chapter

6.Setup (C15 System Settings) for more details).

Change Overview (Panel Unit only)

As mentioned in chapter 3.5 Presets, the

Preset screen will indicate changes (user

edits) to a loaded preset by showing an

asterisk behind the unique number.

When changes occured to a loaded preset,

holding the Shi button while in the Preset

screen will show the Change Overview on

the Panel Unit, as changed parameters will

now have blinking LEDs.

When a changed parameter is selected and

visible in the Parameter screen, an asterisk

behind its label will be shown as well.

Holding the Shi button now will redirect

to the Compare screen, showing the loaded

(initial) and changed (edited) positions

simultaneaously. Both can be recalled by

using So Buttons 2 and 3.

߰ For now, the Change Overview and Compare screen are only available for parameter

positions. Modulation amounts and MC selectors are planned to be integrated as well.
