Notes:

Regarding encrypted files: It is a recent development over the last 15 years or so to data-encrypt audio samples to enforce a copy-protection scheme. Since developers started making their own samplers, they use this connection to allow only licensed users to play their sounds. If it was possible to translate these samples to other formats, it would defeat their copy-protection schemes. Thus, the Chicken Systems Conversion Engine cannot and will not be able to convert out of these formats, as we respect the developer's intent.

Keep in mind that a useable workaround is to use your product's AutoSampler function (if it has one, many Chicken Systems products have it or will have it) or a third-party autosampler. Of course this will require the sampler that can load your source formats, but it's still an acceptable way of getting things into your destination.

Kontakt 6/7: These exist with the same extensions NKI NKM NKB etc. but cannot be read.
Kontakt 5 and lower: Non-encrypted only. Kontakt .nki's that read .nks or .nkx files are classified as encrypted. NKI/NKM that reference NCW files must be resaved as uncompressed in Kontakt to be supported. Can read all information from Kontakt 5 and 4.2 files EXCEPT modulators, filters, and slice information. Kontakt 5/4.2 Banks (.nkb) are not supported yet. NOTE: the .NKB and modulators/filters/slices restriction is NI's restriction, they chose to not let users read these parameters. We have asked them repeatedly for over a decades to change their policy but so far to no avail. We do not expect them to change.
SFZ: Non-encrypted only. As of this writing, the only SFZ files that use encrypted samples are the Garritan Aria-Player libraries. Any SFZ file that references an ".audio" file is encrypted.
Structure: Non-encrypted only; as of this writing AFAIK only the factory library is encrypted. Any Structure file that references a .big file is encrypted.
Giga: Read-only, non-encrypted only; as far as we know only GVI Virtual Instruments are encrypted.
HALion: Non-encrypted only; as of this writing HALion 3/4/5/6 are ALL encrypted. ALL HALion 3/4/5/6 are completely encrypted.
MachFive/Falcon: Non-encrypted only. The MachFive 2, 3, and UVI Workstation factory libraries (usually large UFS files) are encrypted and thus are not supported. All user-written MachFive 2, 3, and Falcon files are supported.
Emulator X: All .exb banks that reference .ebl files are supported. Any sample files that are not .ebl are encrypted and cannot be converted.
Independence: All Independence .ytil files are encrypted and cannot be read, but the Chicken Systems Conversion Engine can create them and show their mappings and audition their samples. The exception is .ytil files that reference samples in the large .ytif images.
SampleTank: Cannot read 2-Pak compressed samples, and; cannot read v3 or v4 Instrument files. Fully reads and writes .pak files (sample data containers). Only writes v1, v2 Instrument files. Note: SampleTank v3 and v4 cannot read SampleTank v1 or v2 files, but SampleTank 3 Free (now called Custom Shop, it free to anyone) has a function that can convert v1/v2 files to v3, for use in SampleTank 3 and 4. However, even though it is a 64-bit app, it does not install on MacOS Catalina and up, it requires MacOS 10.14 and below, or Win7 - Win11.
TALSampler: Non-encrypted only. .talwav files are encrypted, so any .talsmpl instrument that references .talwav cannot be converted.
Reason Refills (.rfl files): Not supported. Any Reason .sxt file that references anything in a Refill cannot be translated.
Recycle: Read-only, Recycle 2 files cannot be written by anything other than Recycle itself.
Stylus RMX: Only includes User Libraries; any Core Library or XPander files are encrypted and thus are not supported.
CAF: On Windows, the Chicken Systems Conversion Engine can only read or write uncompressed types of CAF files.
Hybrid formats: A hybrid format is one that can reference RAM samples and samples indexed in ROM (e.g. a Kurzweil file that loads samples as well as uses the ROM banks.) The Chicken Systems Conversion Engine will convert the RAM sections but not the ROM sections.
Yamaha Motif/Montage/MODX: Often a Yamaha-created Motif Bank will contain LPC/XPC-compressed samples, which cannot be decompressed or converted. The purpose for this is apparantly so no other sound engine can play back the samples except a Motif/Montage/MODX itself.
Alesis Fusion: Often a Hollow Sun-created Fusion Bank will contain compressed samples, which cannot be decompressed or converted. The purpose for this is apparantly so no other sound engine can play back the samples except the Fusion itself.
Proprietary formats on computer: All proprietary formats, such as Akai Programs, E4 banks, etc., have counterpart files that can exist on computer-type drives. These extensions are shown in the list above. A counterpart file may or may not be able to be written or read by the native hardware sampler. The Chicken Systems Conversion Engine can convert into or out of these formats.
