RKR
Convert Korg Kronos sample libraries to SoundFont — iPhone, iPad & Mac
RKR imports Korg Kronos sample libraries (.PCG, .KSC, .KMP and .KSF), converts them once into an internal SoundFont — with the Programs, multisamples and velocity layers — and lets you play, organize and edit them. A Kronos → SoundFont bridge that did not exist on mobile. It exports .sf2, runs as an AUv3 plug-in and never touches your original files.

FAQ
Which files does RKR read?
Korg Kronos sample libraries: .PCG (Programs), .KSC (the collection list), .KMP (multisamples) and .KSF (the samples). RKR bundles them into a SoundFont.
Does it play the Kronos Programs?
Yes. HD-1 Programs become presets in the SoundFont, with velocity layers and key mapping preserved.
Does it convert to SoundFont?
Yes — the output is an internal .sf2 that you play in the app and can export to other samplers.
Does it work as an AUv3 plug-in?
Yes — play inside AUM, Logic, GarageBand, Cubasis and other hosts.
Is RKR affiliated with Korg?
No. RKR is an independent product. "Korg" and "Kronos" are trademarks of Korg, used only to describe compatibility.
