6.6 Delay and Reverb Notes
While only one effect is directly ‘patched in’ the other can be manually
patched with cables. Each channel of the FX module refers to each effect.
Channel 1 is delay and Channel 2 is reverb. There are some consistencies
and interactions in the operating modes that should be noted
• In ‘PCH’ Mode the pitch shifters for each channel are adjustable
/- 1 Octave range.
• In ‘PCH’ Mode the pitch shifters for each channel operate in the
opposite directions. So when the frequency for channel 1, delay
increases, the frequency for channel 2, reverb decreases. This is a
creative choice for interest and uniqueness.
• The clock of the entire DSP processor and A/D - D/A Converters can
be modulated. The speed of processing can change by up to x7
times. This is a creative choice for a unique additional feature in
sound design. The ‘CLK MOD’ amount for a modulation source
connected at it’s ‘MOD” pin will control the speed.
• FX outputs for both channels are in mono by default. Stereo mode
is active in ‘DBL’ operating mode when the ‘MAD!’ pin is set high, for
example patched to the ‘+10V’ Pin. In fact a voltage greater than
+5V will activate. The delay and reverb output pins then become the
left and right stereo outs respectively.
• The ‘CLIP’ LED will illuminate if the input of the A/D Converters of
the DSP processor are overloaded.
• Both the delay and reverb are fed into the DSP effect processor. By
default only one is selected with the ‘FX’ switch but the input pin can
be used to connect the other. For example set FX to {DLY} and
adjust the sound module (FX) knob to send from each sound
generator. Also use the sound output patched to ‘REV’ Input to
simultaneously use the reverb effect.
