10 CueMix FX
OVERVIEW
CueMix FX is a cross-platform software 
application that provides graphic, on-screen 
control for the UltraLite-mk3’s flexible CueMix FX 
on-board mixer and effects processing.
CueMix FX can be used independently of host 
audio software, or together with it. CueMix 
dovetails with the direct monitoring features of 
your host audio software, allowing you to 
seemlessly mix in both environments.
For information about programming the 
UltraLite-mk3’s on-board mixing and effects using 
the front panel LCD, see chapter 10, “CueMix FX” 
(page 61).

A 16-BUS MIXER WITH EQ, COMPRESSION 
AND REVERB
All UltraLite-mk3 inputs and outputs can be 
routed to the on-board CueMix FX 16-bus (8 
stereo bus) digital mixer driven by hardware-based 
DSP with 32-bit floating point precision.
The CueMix FX mixer allows you to apply no-
latency effects processing to inputs, outputs or 
busses directly in the UltraLite-mk3 hardware, 
independent of the computer. Effects can even be 
applied when the UltraLite-mk3 is operating 
stand-alone (without a computer) as a complete 
portable mixer. Input signals to the computer can 
be recorded wet, dry, or dry with a wet monitor 
mix (for musicians during recording, for example). 
Effects include:
■ Classic Reverb with tail lengths up to 60 seconds
■ 7-band parametric EQ modeled after British 
analog console EQs
■ A standard compressor with conventional 
threshold/ratio/attack/release/gain controls
■ The Leveler™, an accurate model of the 
legendary LA-2A optical compressor, which 
provides vintage, musical automatic gain control
The UltraLite-mk3’s flexible effects architecture 
allows you to apply EQ and compression on every 
input and output (a total of 58 channels), with 
enough DSP resources for at least one band of 
parametric EQ and compression on every channel 
at 48 kHz. DSP resources are allocated dynamically 
and a DSP meter in the CueMix FX software allows 
you to keep tabs on the UltraLite-mk3’s processing 
resources.
