2-9  LFO

Two of the modulation sources – the filter envelope generator and oscillator B – are 

described above. The third source is the Low Frequency Oscillator (LFO):

CLOCK 

| 

RATE

  switch: When  set to CLOCK,  the  LFO follows the  Clock  setting (see 

Clock / Sequencer on page 21).  The RATE option here allows LFO speed to be freely 

adjustable via the RATE knob…

RATE 

knob: Adjusts LFO speed within a range of about 0.1Hz to 30Hz.

SHAPE 

switches: The same options as in OSC B except that the LFO’s pulse width is 

fixed at 50%. Remember that you can add the shapes here e.g. SAW + SQUARE.

2-10  MODULATION SIGNAL FLOW

Repro-1 offers three modulation sources which can be mixed and routed through two 

different paths to five modulation targets:

INTRO   SYNTH   SEQUENCER   KEYS-PERF   EFFECTS   TWEAKS   CONFIG   NKS
