Hexter is a DX7 synth emulator developed by Sean Bolton. It is a realtime, polyphonic/monophonic, synthesizer that can import the SysEx sound files directly from the classic Yamaha DX7 synthesizer. Output is mono. This lastest version shown below is version 1.0.2, which allows an entire patch edit interface, which can be displayed in two styles: "Widgy" or "Retro."
Hexter can run within most DAW hosts as well as standalone, using jack-dssi-host (
jack-dssi-host /usr/lib/dssi/hexter.so) or Ghostess (
ghostess hexter.so), which are both available in most repositories.
A whole slew of patches have been collected for Hexter, and can be found HERE. --In particular, download the "DX7EXTRA.zip" "all-syx.zip" and "deckard.zip" packages, and "dx7.zip" which is found by clicking the "zicweb" link.
