Nonlinear Waveform Combination Modes
The outputs of the two oscillators are sent through a nonlinear combination process before going to the echo/
delay effect and then onto output 1. The combination process allows the generation of complex timbres and
interactions between the two oscillators, as shown in the figures on the next two pages.
Press the COMBO MODE button to activate the rotary encoder for selection of the combination mode. The
selected combination mode will be shown in the bottom row of the LCD display. The COMBO MODE parameter
can also be modulated by the MOD B input, which is activated with a second press of the COMBO MODE but-
ton. When MOD B modulation is active the lower row of the LCD display will change to show both the nominal
setting and the offset provided by the MOD B modulation.
There are 8 different combination modes that can be selected:
cmb:osc1 - in this mode there is no nonlinear combination. The output of oscillator 1 is taken as is.
cmb:ring - in this mode the outputs of oscillator 1 and oscillator 2 are multiplied, equivalent to the well-
known ring modulation effect.
cmb: min - in this mode either the output of oscillator 1 or the output of oscillator 2 is chosen, depending
on which one has the lower value.
cmb:pong - in this mode the output of oscillator 1 is chosen if it has a positive value, otherwise the output
of oscillator 2 is chosen if it has a negative value. If neither of these conditions holds, then the output is
set to 0.
cmb:inlv - in this mode the digital bits representing the two oscillator waveforms are interleaved to
provide the output of the combination process. The most significant bit of oscillator 1 is used as the most
significant bit of the output, the 2nd most significant bit of oscillator 2 is used as the 2nd most significant
bit of the output, and so forth, alternating between taking bits from oscillator 1 and 2.
cmb: and - in this mode the digital bits representing the two oscillator waveforms are combined using the
logical AND operation (the AND operation produces a 1 bit when both the input bits are 1, otherwise it
produces a 0 result).
cmb: xor - in this mode the digital bits representing the two oscillator waveforms are combined using the
logical XOR operation (the XOR operation produces a 0 bit when the input bits have the same value, oth-
erwise when the bits have different values it produces a 1 result).
cmb:gLcH - in this mode each bit of the output of the combination process is set to 1 whenever the re-
spective bits of oscillator 1 and 2 both become 1, and is set to 0 whenever the respective bits of oscillator
1 and 2 both become 0. Otherwise the bits hold their value constant. Whenever the 2nd most significant
bit of the combination goes from 0 to 1, the phase of oscillator 1 is ‘bumped’, or offset, by a step of 1/4
cycle (or 90 degrees of phase) and the phase of oscillator 2 is bumped by a step of 1/8 cycle (or 45 de-
grees of phase). The overall effect of this rather complicated combination is to provide a noisy and glitchy
sound.
