Some Yamaha DX100 / DX27 Synth Patches

I’ve owned a Yamaha DX100 synthesizer for decades and never really had a strong grasp as to how the heck you build sounds with it. The last few months I have been immersing myself in FM synthesis and I think I finally have a handle on the concept now. Here is set of twenty-four patches that I created:

They all sound better and less brittle with a little reverb and chorus, but you get the idea. I especially like “Astro Pong” and “LoocySynth”. If you like what you hear, you can download a .WAV file of the cassette dump and load these patches on to your DX100/27 via the cassette port hooked to your PC. Just make sure your PC’s volume is turned way up or the DX won’t hear the data stream.

UPDATE: I have finally saved these patches as sysex files (see below). Here is information on loading sysex on to a DX100 (also contains separate sysex files for each of the individual patches).

  1. Thank you very much!
    But do you mind to send me the SOLID BASS .syx or .sysx. please?
    I’m looking for a genuine data from a genuine Yamaha DX100 device for years.

  2. Hi, I too have recently gone back to my DX27 after a couple of decades. Having connected to my PC using MIDI I have been downloading SysEx files. However I am interested in bulk uploading from an archive of voices I have created in Excel. Only thing is I cannot find anything explaining how to calculate the check-sum for the DX27. Is this something you have come across at all.
    Thanks for the voices you have created.
