  7. Real-Time Controls

The real-time controls give you immediate 
access to all of a channel’s key parameters 
(or the key parameters of all of the channels 
in Hex Mode).

Before we get into the individual controls, 
here are some things to keep in mind:

Option Modes

Most of the controls operate in a 
primary mode, labeled on the panel 
in black, and one or two Option 
modes, labeled in blue. Option 

modes are accessed (for Option 2) and then 
turning the control.

A NOTE:

 Clicking the Hex button while an 

Option mode is active latches the Option 

mode. That is, you can release the Option 
button and Option mode continues to be 
active, letting you adjust multiple Option mode 
parameters without having to hold down the 
Option button.

When an Option mode is latched, clicking the 
Hex button unlatches it, returning the module 
to primary mode.

ANOTHER NOTE: 

While an Option mode is 

latched, clicking the Option button cycles 

sequentially through the three modes: Option 
1 to Option 2 to primary.

When in Option 1 mode (either by holding 
the Option button or when latched), the Hex 
LED blinks at 4 Hz to indicate that. When in 
Option 2 mode, the LED blinks at 8 Hz.

YET ANOTHER NOTE:

 As described 

elsewhere in this manual, clicking and 

holding, or double-clicking and holding the 
Option button enables a number of other 
functions. Latching an Option mode latches 
the ability to execute those functions as well. 
Specifically:

When Option 1 is latched, the Channel 
Output Viewer is active and clicking a 
Channel Selection button triggers or resets 
the phase of that channel.

When Option 2 is latched, the Preset 
buttons function as CV Mode Selector 
buttons.

AND YET ANOTHER NOTE:

 Some of the 

controls do not have a dedicated Option 

2 function. In those cases, their Option 1 
function will also be available when Option 
2 is selected. In the detailed descriptions that 
follow, those functions appear in parentheses.

Knob Behavior

When switching between channels for 
programming, you will often find that a 
knob’s current position doesn’t match the 
value of its parameter in the newly selected 
channel. As long as you don’t adjust the 
position of the knob, the parameter in the 
newly selected channel will not be affected. 
However, as soon as you do move the knob, 
the parameter will change to the knob’s 
physical position.

Hex Mode

When in Hex Mode, the real-time controls, in 
most cases, affect their parameters in all six 
channels. However, there are a few instances 
where certain functions are only available 
when in Hex mode. These are indicated on 
the panel with orange labels.

Channel Frequency Range

It’s important to remember that a channel’s 
initial frequency (before any CV control) 
is defined by the product of four of the 
real-time parameters: Frequency, Octave, 
Harmonic #, and Variation. In Hex Mode, 
Frequency and Octave can be further offset 
by their Hex Mode parameters. And, of
