Kurzweil to PropellerHeads Reason NN-XT Translation

Translator takes each Kurzweil file (.krz, .k25, .k26), creates a folder for it, then takes each Program and creates a Reason NN-XT file for each one, putting it into that folder.

Kurzweil envelopes can have up to 6 rates and levels to them; Reason NN-XT only supports a single ADSR-type of envelope. Translator uses complex transfer functions to best approximate these envelopes.
