Tranzilon is a tool to create transwaves for use on the Ensoniq EPS 16+ or Ensoniq ASR-10 sampler. The program is freeware and can be downloaded here.
The transwave that is generated by Tranzilon will consist of 100 waveforms, starting with the upper-waveform, and slowely transforming into the lower-waveform. When Epsilon uploads this wavesample it will tell your EPS/ASR that it is a transwave. This way, when you play your keyboard, only one of the 100 waveforms will be heard, but by using the modulation wheel you can select each of the 100 waveforms. This is the default transwave setting done by Epsilon, but you can manually override this. You can let the selection of the waveform be based on key-velocity, envelopes, random etc. See your EPS/ASR manual for more information about this.
