I've been trying to reverse engineer the system exclusive voice dump format of the DSR-2000 keyboard. It is powered by the 4-operator Yamaha YM2414 OPZ chip, similar to the DX11, TX81Z, and a few others. The DSR-2000 is probably the most powerful FM keyboard Yamaha produced with the Portasound label (i.e., marketed to non-musicians), and a sysex editor would bring it up to the fully-programmable level of the professional keyboards.
Portasound JS
This sysex breakdown was used to create the DSR-1000/2000 layout in the Portasound JS online editor. If you are one of the few people who actually own this keyboard, do let me know if it works!

I really dont understand the table, but I'm happy to see this!!
Keep good work!
Best regards!

/ May 4, 2022 QuoteThe Portasound JS sysex editor is overall responsive, but there are a few quirks.
I thought I could use it on a Mac notebook, but the editor for Mac won´t detect the interface (iRig MIDI2). It does get detected on an ASUS laptop running on Win 10. That´s pretty odd.
Also, any use of a sound parameter in the editor will cause the DSR2000 to always automatically redirect to User voice 01, which seems to be the default sound. Is it not possible to select one of the preset voices (presets 40 to 99) and work from there?
And what is supposed to be done with the parameter test bench? Any parameter use just mutes out the sound. It looks very versatile though.

Are you still actively working on this / using this and is there a potential download of the program we could get so we're future proofed?

Can I load my program from DSR to this editor?

It should be possible, but I didn't make the effort yet. The same goes for the 480/580 series presets.
> And what is supposed to be done with the parameter test bench?
It is just a flat layout of the entire 80 sysex bytes so that you can see individual bits. Helps to identify those one, two, and three-bit parameters. You have to set a few of the sliders just right or it will make a silent patch, but I forget now.

/ May 23, 2024 QuoteI just picked up a dsr 2000 and found this. I'm having some trouble getting this working in general. Running a MIDI from the keyboard to my volt 476 which I can select on the site but I haven't been able to make this work. Can anyone provide some help or information on setting this up?
