Set the 16 linear potentiometers
3.4.2 The LFO
On the original ARP 2600, oscillator2 could be set to low frequency position (“LF” position in the
range) for use in LFO mode. Although practical, this solution prevented us from using 3 oscillators
simultaneously and a slow modulation on the filter cut-off frequency for example.
Thanks to the LFO module situated on the “Keyboard control” module of the “All” mode, you can
keep the third oscillator as base sound and obtain an additional source of modulation for one of the
13 available destinations. It is also possible to synchronize the clock speed of the LFO to that of the
MIDI sequencer by clicking on the “MIDI sync” interrupter.
Apply two additional types of modulation to the preset “1_Osc”:
For example: the LFO is “pre-cabled” to obtain a vibrato (simultaneous frequency modulation)
of the two oscillators. Simply raise the linear potentiometer “Vibrato Depth”, situated on the
LFO module, to create this effect.
Raise the “Vibrato Depth” potentiometer
Another example would be to click on the LFO triangle output and direct the cable to the “VCO2
sin” modulation input of the filter module. Raise the potentiometer above it. Lower the cut-off
frequency to hear the result more clearly. The brightness of the sound will vary in a cyclic fash-
ion, to the rhythm of the LFO.
