This is probably a shugart floppy disk drive (as many others keyboard/samplers)

What is the sgroup page's file images format ?

You have to change the .out file extension to .img. After this you can convert them with the hxc floppy emulator software.

That's all.

ok i copied the image files and cfg on the drive, but it does not seem to load the OS. it beeps once but then it stays quiet,
the best shot was when i used jumper 1.

could you tell me which jumper setting could work ?

right now i have the default settings...

here is a pic on the setting that are on the factory floppy :

Change the setting to Shugart and reconvert the files.

hi hossegor or someone else,

could you describe, what exactly you did, to make the hxc work on the S750.

I couldn´t get it to work. :(

I tried shugart mode, pc 1.4 mb....., but no result.

the 750 here is just kind of reading track 0 and 1 repeatedly


thanks :)

OK, this is how you get the HxC working with the Roland S750/S770 (Thanks Jeff for the research and the effort)

To get a working image for the HxC , you can dump a Roland Floppydisk with the HxC software on a PC.

Important, when you export the dumped disk are the emulator settings. but instead of "shugart" it you need to choose IBM PC 1.44MB or IBM PC 720KB, dependent on the desity of the dumped floppydisk.

You can also use the Images from the S-Group Site linked before. Change the extensions (.OUT, .SDK) to ".IMG" and batch convert the files into .HFE

Here it´s also important to choose the right settings when you convert the .IMG files to .HFE .

Switch on your Sampler.

Go to the HxC hardware and check if "Interface CFG" is set to "From HFE File" (to get there hold middle button)

Insert the SD card and select a Roland S750/S770 Systemdisk.

If the Systemdisk is loaded, you´re fine. Then it works already.

If it still doesn´t work, you will need to add two resistors to line 2 and 32. This can be done on the board of the HxC .

Add two resistors to R11 and R16.

Resistors between 1kΩ to 2,2kΩ should be fine (Jeff said) .

If you still don´t get it to work try again and check all steps again.
