Try the following scheme for decoding the length and offsets. I think the results of your well-designed tests help explain pretty much everything. The string "TESTSTRING123" precedes the string "PREFIX.SUFFIX". Here is an example which should demonstrate how the lenght field is computed: Shannon entropy is 5.84154 for the data chunk which is somewhere in the middle between english text and encrypted. The string "TESTSTRING1" and "PREFIXTESTSTRING1SUFFIX" are contained in the uncompressed stream. Does anyone know about a similar format that has been successfully decoded?.What compression scheme could be applied here?.

The files do not seem to contain any dictionary for compression which makes me think the dictionary must be stored somewhere else or there might not be a dictionary at all.

If "THIS_IS_A_MACRO_NAME_ABC" is preceding "THIS_IS_A_MACRO_NAME_XYZ" in the stream the second string will be compressed to "_XYZ". Compression seems to reference previously encountered strings and reference these strings in later portions of the stream:

for user defined macros there seems to be some sort of compression applied to the raw data.

The main section of the preset file seems to be compressed, while synth parameters should be float values between 0 and 1 they don't seem to be written as floating points into the file - apart from unrecognizable binary values there are plaintext strings e.g.changing a single parameter in the synth changes some bytes at several places (3-4) in the file.The vst binary chunk returned by effGetChunk vst sdk api calls are 99% similar to the.File contains some fixed length sections introduced by "DSIN", "hsin" markers.

fxp format for automated loading and rendering of presets through the vst api.įrom experimenting with saving the files when changing synth parameters I've found out following facts about the format: Reason for this endeavour is to convert the above formats to general vst. The file format is binary with several sections. I'm trying to decode the file formats for Massive, FM8 and absynth VST synths.
