Ocean Swift Sample Tester is a FREE Kontakt Player NKS, compact, zero-friction tool for anyone working with oscillator-style samples.

Drop a file in, play it polyphonically, and know immediately how it behaves in context. The instrument detects (or lets you set) the root note, reports MIR-derived metrics at a glance, and lets you hear the sample either streamed directly or stretched with Time Machine Pro – so you can decide what belongs in your kit, SD card, or Eurorack module.

Sample Tester is designed as the perfect companion to our Spectral Oscillator Toolkits – and equally useful for any tonal or looped material – Sample Tester speeds up curation, tuning checks, and quick musical auditioning with a simple envelope and tactile NKS/NKS2 control.
