Building DX7 patches without RAM cartridge

Unread postby synthElik » Fri May 19, 2017 5:12 pm

Hi,

I just picked up a DX7 mark 1 from a friend who wasn't using it. I wanted to take a stab at FM synthesis to build some harsher sounds (a la Juno 106), but I don't own a RAM cartridge. All I have is the physical DX7 and the ROM cartridge with the manufacturer patches on the A side and some additional sounds on the B side. Do I need a RAM cartridge to make patches, or can I simply do so on the internal storage and reload the manufacturer patches from the ROM cartridge onto the internal storage later? Or is there some other solution?

Also, I know DX7 mk 1 has MIDI, is it possible to load libraries that others have built onto it from a PC?

Thanks

Hi synthElik,

welcome to the Yamaha forums - glad you've found us here :D

No, you don't need a RAM cartridge - you can 'create' sounds and store them to the DX's internal memory 0-)

As you supposed - yes, you can reload the factory sounds from the ROM cartridge back into the internal memory.

And yes, it is possible to load libraries (that other peolpe have created/collected) via MIDI into your DX7. What you need is an appropiate program (DX Manager, MIDI-Ox, DXFactory - just to name a few) and - most important - a RELIABLE MIDI interface! Beware of those 'El Cheapos' - they mostly have only a small buffer and cannot dependably handle larger sysex files 8O

If you haven't still got an interface - those midisport 2x2 or 4x4 USB to MIDI are known good - amongst several other brands of course :wink:

Hope this helps

Best regards,
Miks

Hi Miks,

Wow thanks for the quick reply!

I assume that if I can pull libraries in from a PC, I can also build my patches on the internal memory, push the internal memory off to a library on my PC, and then reload the ROM data, right? That way I can save my patches for later. Is there any documentation on the upload/download processes?
Also, Is there anything that I should beware of when reloading the ROM cartridge data and uploading/downloading libraries - anything that can go wrong?

As for a MIDI interface:
I have a Focusrite Scarlett 2i2 Audio Interface which I use for recording guitar etc, and it supports MIDI. Is this sufficient?

Thanks again!

Yes.

See DX7 user manual and the manual/help file for the program you want to use for MIDI transmission.

Well - delete your patches on your DX AFTER having saved them SUCCESSFULLY to your PC. Downloaded Libraries CAN be corrupt and cause several errors when sending them to a synth. So it's not always the synth causing loading issues... 8O

Are you sure the 2i2 has MIDI? I did a short Google search and found the 2i4 being equipped with MIDI In & Out jack... 8O

Ok yeah makes sense. I don't have to worry about corrupted libraries damaging the actual DX7 software though right? I'd rather not do anything irreversible haha.

Oh, you're totally right, I don't know why I thought it did... Ok I'll figure something else out then. I have a simple MIDI to USB converter that I use for triggering electric drums, but that was fairly cheap (~$35) and I feel like that could be iffy.

No, corrupted libraries are not able to damage the synth's software (aka firmware). But they may be able to damage the sounds stored to the internal memory - nothing that can't be 'repaired' :wink:

You can try this for your DX - it may work well. But if not you have to fathom where the problem lies... could be the MIDI interface, the program you're using etc...
