Element DescriptionGrind Adjusts the grittiness of the “aero” component of the sound, measured as apercentage. Available values range from 0.0 to 100.0% (default: 45.0%). Lowvalues produce a boomy reverberation. High values result in a crushed, digital“air” squashed into the drum sound. Note that this parameter will only have aneffect if Amount is set to a non‐zero value (see below).Amount Controls the amount of air or grit in the kick sound, measured as a percent‐age. Available values range from 0.0 to 100.0% (default: 20.0%).Advanced PageFor this engine the Advanced page does not contain any parameters.Modulation PageLike with all other engines and Drumsynths, the Modulation page contains one parameter: Veloci‐ty.Element DescriptionSCALE SectionVelocity Adjusts the velocity response of the drum. Available values range from‐100.0% to 100.0% (default value). At zero (mid course), the drum is played atfull velocity, no matter how hard you hit the keys (or pads). From that mid po‐sition, by turning the knob to the right you increase the positive velocity re‐sponse and make the drum more sensitive to the velocity at which you hit thekeys/pads. From the mid position, turning the knob to the left as the inverseeffect: the harder you hit the key/pad, the softer the resulting drum sound willbe.8.2.5 Kick – RasperThe Rasper kick is an acoustic bass drum emulation providing a unique and organic sound thatcan be easily adapted into Drum’n’Bass or Dubstep productions. Its two crispness modes allowfor a wide range of bass drums.Using the DrumsynthsThe KicksMASCHINE ‐ オペレーション マニュアル ‐ 311
