In Session Audio Fluid Strike is an instrument designed to create richly layered melodic percussive patterns with ease.

Why is it called Fluid Strike: Tuned Percussion?

“FLUID” because of the flowing sound created with the three arpeggiators.

“STRIKE” because the instruments have been struck with mallets, sticks, brushes & fingers.

“TUNED PERCUSSION” because the library features 30 melodic, percussive instruments (complemented by a selection of 120 synth sounds).

Why tuned percussion?

Because the instruments are timeless...
Wood, steel, stone, bamboo, glass and gourds combine to make a sound that is elemental. A sound that can harken to both the past and the future. With a slew of effects, sound shaping tools and autoplay rhythmic and melodic features at your fingertips, Fluid Strike allows tuned percussion to sound completely unique. 


In Session Audio didn’t stop at sampling each instrument just once. Where possible, each instrument has been recorded using a variety of sticks, mallets, fingers, brushes and bows.

For example, the vibraphone is offered played with soft mallets open and muted, rubber mallets open and muted and bowed! Choose what you need.

Between the 30 instruments recorded for Fluid Strike, there are 63 different sample sets!

You can find a complete list in the Contents tab.


Triple Play Engine

For years, In Session Audio had been wondering - "What if we could create an instrument that allowed the user to:

  • Select three sound sources to layer together
  • Arpeggiate the three sound sources with independent patterns, rates and playback modes
  • Shape and effect the three sound sources independent of one another
  • Select any effect directly from the interface (and swap their positions on the fly)
  • Humanize the three sound sources independent of one another?"

After nearly six months of development, they did it!



Native Kontrol Standard (NKS) is Native Instruments' extended plug-in format.

NKS allows for seamless interaction between FLUID STRIKE and KOMPLETE KONTROL and MASCHINE hardware.
