Low-frequency Oscillators (LFOs)In addition to the main oscillators, the MicroWave II/XT/XTk is equipped with two low-frequency oscillators which can be used for modulation purposes. Each LFO generates aperiodic waveform with adjustable frequency and shape.LFO 1LFO 1 / 1LFO 1 / 2Rate0…127 (128 Bars…1/64)Determines the frequency of the generated signal. If Sync is set toClock, the value isshown in musical notation. The basis is a 4/4 beat. Triplets (e.g.1/8T) and dotted notes (e.g.1/16.) are available for some values.Shapesine / triangle / square / sawtooth / random / S & HDetermines the type of waveshape to be generated. Sample & Hold samples a randomvalue and holds it until the next LFO cycle begins. If Rate has a value of0, then a randomvalue is generated for each new incoming MIDI note. More variations can be achieved bymeans of the Symmetry parameter. Please read the corresponding paragraph later on inthis chapter.Delayoff / retrigger / 1…126Determines the start of the LFO cycle after an incoming MIDI note.• Ifoff is selected, the LFO runs completely free, which means its cycle is notsynchronised to the note start. Use this setting e.g. when modulating the filtercutoff of a sound that should be different each time you play it.• Ifretrigger is selected, the LFO starts its cycle after receiving a note. This is alsoknown as "key sync" feature. This setting is useful when the LFO must always startat a fixed value, e.g. when creating an alert sound.• If1…126 is selected, the LFO is works like inretrigger mode, but is delayed withthe specified amount. This setting is useful e.g. for solo sounds with a vibrato ortremolo that is only applied on long notes.Syncoff / on / ClockSelects if the LFO is synchronised. Ifoff is selected, the LFO runs completely independent.Ifon is selected, all LFOs of the MicroWave’s voices used by the sound program behave asone. IfClock is selected, the LFO is synchronised to an incoming MIDI Clock signal.Symmetry |Humanize+27 | 003Rate | Shape | Delay | Sync028 |triangle | 005 | off78 User’s Manual MicroWave II • MicroWave XT • XTk
