what is it:

a software application that lets you program your Oberheim DSX sequencer with MIDI files from your computer! Turn your DSX into an 8 track CV/Gate sequencing monster!

New version 1.1 available! (see Version History in Documentation for info). Free upgrade for existing users!

what are its features:
• remove constraint of requiring an Oberheim synth to program the DSX
• convert
a MIDI file to any of DSX's 10 sequences
• easily program each of DSX's 10 merges using your computer
• send sequence info to any/all of the DSX's CV/Gate outputs to control your analog synths
• save DSX sequences and/or merges on your computer as audio files for easy re-use later

"The Oberheim DSX has a special place in my heart since it was the very first commercial product I developed. It is quite amazing to see it able to be put to practical use again 35 years after its introduction, thanks to DSX Hack!"

"Congratulations on your accomplishment! This sounds like a great way to revitalize an old DSX for use in a modular synth system."
