I very much like modulation by pedal of filter frequency and cross modulation.  
As long as the mixer modulation feature is not available, there is a possibility to create a morph between two different sounds of DDS1 and DDS2 by using pedal modulation of DDS2 pulse PW:

- make a sound with both DDS1 and DDS2 by using the pulse wave of DDS2
- make the pedal modulate PW of DDS2 pulse (section DDS modulator) with up to 100%  
 → if PW is 100%, only DDS1 will sound and DDS2 is off
