- Basic Operation

Left side /// SMOOTH mode

In 

CYCLE mode 

(switch down or CYCLE OUT connected to IN), the OUT produces a nice triangle wave . The 

RATE knob controls an enormous 

frequency range of appr. 26s/CYCLE to appr. 20(!) kHz

 . Turning the CYCLE 

mode on via the switch disables the IN .

In 

INPUT mode

 (CYCLE mode is off), the OUT follows the IN as quickly as the RATE parameter allows . A high at 

the HOLD input will freeze the OUTPUT .

Right side /// STEPPED mode (and more)

The right side also has a 

CYCLE mode 

(switch down or CYCLE OUT connected to IN) . However, the OUT 

depends on the Sample (SMPL) input and the corresponding MODE switch as well as on the RUN input:

• 

Smooth Mode

: Set the SMPL switch to center to let the right side run freely - both the SMPL input and 

the RUN input are ignored . The Stepped side now pretends to be “smooth”, producing a triangle wave at 
the OUT . The RATE knob controls a 

frequency range of >1min/CYCLE to 8 kHz

 .
