Understanding the LFO2 Module and MIDI Implementation

MIDI WAVEFORM TYPE
The LFO2 module has six waveforms available from the front panel as documented in the manual. These
waveforms can also be changed via MIDI CC95: LFO2 MASTER WAVEFORM. Please refer to the
manual page 79 for a reference to the actual CC definitions.
From MIDI CC95, one can select the six waveforms from the front panel and additionally a SINE
waveform. (The last waveform via MIDI is reserved for future use.)
Sending a MIDI CC95 to the LFO2 manual will change the waveform for both the LFO(+) and the LFO(-)
outputs of the module.
Additionally, one can control the waveforms of LFO(+) and LFO(-) separately via MIDI only. This gives
the LFO2 module a great degree of flexibility and deepens the types of signals you can generate with the
module. Please note that the phase relationship of the two LFO’s are always preserved. This means that
the rates of both LFO’s are always identical and that the time relationship between each LFO (phase) is
also preserved. Thus, even when you change the waveform type, the waveforms remain complementary
in phase.
Changing individual waveforms via MIDI is done using the following two MIDI CCs:
• MIDI CC105: LFO(+) WAVEFORM TYPE
• MIDI CC109: LFO(-) WAVEFORM TYPE
Changing the waveforms using the MIDI CC95 or the front panel switch, immediately resets the LFO(+)
and LFO(-) outputs to be the same waveforms and true complements of each other.
UNIMPLEMENTED MIDI CCs
As per the manual, page 79, there are a number of LFO2-related MIDI CC’s that are not implemented but
defined on the instrument so that these remain reserved for future use.
Currently these are CC102, CC103, CC104, CC106, CC107, and CC108.
DEFINING MIDI CHANNEL
The LFO2 module ALWAYS comes up defined as MIDI Channel 1 when you power-up your Voyager XL.
Care must be taken not to create MIDI CC conflicts with any other MIDI device that is attached to the
MIDI chain. It is best to set other devices to channels 2-16.
If you are in a situation where you need to use MIDI CHANNEL 1 for another device in the MIDI chain,
you can reassign the LFO2’s internal MIDI channel by sending a MIDI CC110: MIDI CHANNEL
NUMBER. (Note: you can change the Voyager XL’s main MIDI channel from the main user interface.)
MIDI CC110 is handled by the LFO2 module independent of which channel it is being sent on. So, for
example, to change the LFO2 MIDI CHANNEL from 1 (default) to 5 you would send a MIDI CC110 with a
value of 5. After sending this, the LFO2 module will only respond to MIDI that is sent to channel 5.
