 | SOUND MODIFIERS

can have a different combination of sound sources 
sent to each of the 

fi

 lters at the same time. There is a 

gain boost after the 

fi

 lter signal, and the signal output 

path from each 

fi

 lter is then sent to the pan and level 

section. (If the upper Filter section is disabled, the raw 
Mixer output is sent to the pan and level sections.) 
Each Filter Level can be controlled by a knob on the 
surface, by any of the envelopes, or any of the other 
modulation sources listed. Using these, you can create 
separate articulated shapes for each 

fi

 lter’s output - al-

most a ‘multi timbre’ approach to the sound, enhanced 
by the fact that each can also have its own envelope 
and pan position. 

With the Filter outputs as possible signal inputs, you 
can create feedback loops within each 

fi

 lter section, or 

have the function of series 

fi

 lter connections (the 

fi

 lter 

output is taken before the pan module, so the series 

fi

 lter signal’s panning is determined by the last 

fi

 lter in 

line). You also can get some useful and strange distor-
tion of the 

fi

 lters if desired, among many, many other 

things!

Filter Page Views

The Filter Section has two main views, the main Filter 
+  Filter Mixer pages for 

fi

 lters 1-4 and the 

fi

 lter Output 

page. Clicking on F1, F2, F3 or F4 will display the 

fi

 lter 

and 

fi

 lter mixer settings for that 

fi

 lter. Solaris’

Table 4: 

The control pages for 

fi

 lters 1-4 can be accessed by 

clicking on the page buttons F1-F4, respectively. The 4 
Mixer/Filter sections are identical, and each section is 
composed of:

A 

fi

 lter which can be activated or bypassed

•

A four channel input mixer: This pre-

fi

 lter mixer 

•

gives access to up to four oscillators’ signals (which 
means up to 4x4…16 separate oscillators for the all 

fi

 lter sections)

This switches the  modulation destina-

cutoff to the

 lter’s resonance

Mod 1, Mod 
2, Mod 3

These control the  modulation path to 
the 

fi

 lter cutoff

Boost

Up to 12 dB of gain can be applied 
post-

fi

 lter. High levels will give a distor-

tion that may or may not be desired
