Frequently asked questions
How do I turn WAV samples into a playable instrument?
Drop up to 24 one-shots. Each gets a detected root note and a keyboard zone. Play the on-screen keyboard or QWERTY keys, correct any wrong note, then export the ZIP. Open its .sfz in an SFZ-compatible player such as sforzando, or its .dspreset in DecentSampler; keep the accompanying samples with the preset.
Which sampler can open an SFZ or DecentSampler preset?
SFZ is a text-based instrument definition used by compatible players such as sforzando. DecentSampler uses the .dspreset format. These are not native Kontakt .nki instruments; check your chosen sampler's format support. Exporting a preset does not remove copyright or licensing restrictions on its source samples.
What if a root note is detected wrong?
Noisy, percussive, or layered samples can produce unreliable pitch estimates, including octave errors. Check the note by ear; click the sample and choose the correct key to remap it. Treat the detected note as a starting point, not a guarantee.
How many samples make a good instrument?
One sample per octave is playable; one every major third sounds natural; every note is sampling royalty. Even 4–6 well-spread one-shots make a surprisingly musical instrument once zones fill the gaps.
