5.  Presets can be selected by pressing the PRESET down or up switches, then 

the RECALL 1 switch.  Holding the PRESET down or up switches will result in 
progressively faster scrolling through the preset titles.  The RECALL 2 switch 
will  immediately  increment  one  preset,  and  the  RECALL  3    switch  will 
immediately  decrement  one  preset.    These  can  be  used  to  step  through  the 
presets  to  try  them  out.    The  RECALL  4  switch  will  jump  back  to  the 

last 

previously recalled preset, easy to remember since it is the 

last switch

 on the 

right.        If  the  preset  title  is  displayed  (if  FUNCTION  is  set  fully 
counterclockwise), the VALUE knob can be turned to scroll through the preset 
titles.  Pressing the RECALL 1 switch will then recall the selected preset. 

6.  BOOST, PHASER, TREMOLO, CHORUS, FLANGER, DELAY, and REVERB 

can be turned on or off by the top row of switches, depending on the settings 
within each preset. 

7.  Pressing the SECOND switch allows access to the WAH on/off, STORE, and 

SONG  Mode,  as  well  as  TAP  functions  to  set  the  modulation  rates  and 
DELAY  time.    The  FUNCTION  knob  selects  the  function  such  as  Preamp, 
EQ, etc.  The PARAM knob selects the parameter within the function, and the 
VALUE knob adjusts the value. 

8.  Changing a value will light the red STORE  LED.  To store the new value for 

later recall, press the 2

nd

 switch, followed by the STORE switch.  Note that the 

THETA PRO DSP ships with the Preset 1-100 and Preset 101-200 LOCK set 
to  ON,  so  storing  to  those  presets  will  display  a  FAIL  message.    Storing  to 
presets  201-224  is  always  allowed.    See  the  section  on  the  Global 
Parameters for more information on how turn off the Locks. 

9.  To copy a preset to a different location, first recall the preset.  Then scroll to 

the  desired  new  location  by  using  the  PRESET  down  or  up  switches,  or  the 
VALUE  knob  (if  FUNCTION  is  set  fully  counterclockwise).    Note  that  the 
preset titles will flash, meaning the preset is not fully recalled.  Then press 2

nd

STORE  to  store  the  last  recalled  preset  into  the  new  location.    The  original 
contents of this location will be overwritten, so be careful.  The unit ships with 
100  unique  presets  written  in  locations  1  to  100,  then  repeated  again  in 
locations 101 to 200, we recommend that one of the two banks be left locked 
to  prevent  inadvertently  writing  over  the  original  presets,  at  least  until  the 
storage space is needed for new original presets. 

10. Read the rest of the manual, it contains much valuable information to get the 

most from your Theta Pro DSP!
