REAKTOR SPARK – 36MC1 has as its modulation destination in addition to the aMplituDe and DriVe paraMeterS twoparameters which can be chosen from the two drop-down menus. The modulation amountfor these modulation controls can be set by the corresponding faders. Sliding the fader to theright causes positive, sliding it to the left, negative modulation amounts. This means that forpositive modulation amounts the destination parameter is increased as the Macro Controlleris increased in value. For negative modulation amounts the destination parameter would bereduced as the Macro controller is increased in value.As with Mc1, the MoDulation controller 2 has two preset modulation destinations: the filtercutoff frequency and the filter resonance parameters of the Ringmod/Filter section. Two ad-ditional parameters can be chosen as the modulation destination for Mc2 from the drop-downmenus. The preset modulation destinations of the MoDulation controller 3 are the amountof the feedback signal at the input of the Ringmod/Filter section and the Cabinet Mix, as arethe two parameters that can be selected from the drop-down menus.4.14 LFO SectionWith these controls you can adjust the main LFO parameters.SPARK also has an LFO with a triangle waveform with adjustable symmetry and clipping asan internal source of periodic controller movements. It can replace the automation of the hostsequencer or the pedal movements and lets you get your hands free for sound modifications.The LFO can have four destinations: the MoDulation controllerS 1, 2, and 3, and the Velocitycontroller. The routing of the modulation signal to each destination can be switched on oroff with the to Vel, to Mc1, to Mc2, and to Mc3 buttonS for the Velocity Controller, MC1,MC2, and MC3, respectively. These buttons are located on the left of the correspondingcontroller’s fader.
