my bad i thought it could as it can do the other conversion i assumed it did it both ways tho i never tried just tried the 4op to 6op from my tx81z sysex banks great app tho

DXconvert can do a lot of things, but converting dx7 to 4-op is NOT one of them. It can only convert 4-op to dx7 (6-op) -- MT

Hello! I'm curious what EPROM Burner you use for this line of work. I've been tempted to buy one myself but am not sure which make and model would be well suited for these old synths. Thank

Thanks for the follow-up. For those interested, IC14 is the ROM, while IC20 & IC21 are Static RAM chips.

Fixed! Had to replace IC 14, IC 20, and IC 21 Chips. Works great now.

You only need a USB Midi port. There are some that are not very expensive. There models from E-MU and M-Audio for under 40$ brand new. You can probably also find one used at good price on local adds

i use a midisport 4x4 usb interface that works with my dx7ii and my sy99 i use dx manager and it allows me to read and dump sysex to all my dx instruments and allows me to convert to sy77/99

Thanks guys. ?I guess I need to do some shopping (and a bit of learning). ?I've been telling myself that every so often, ever since I got the first DX over ten years ago. I know the files are

Hi David, Whatever cardtridge you have must be available in sysex somewhere on the net. Then do a MIDI dump from your PC, if you have a MIDI port. I don't see how else you are going to do that,

Hi david, Looking at my TX802 manual which is a DX7II in a rack you can read (but not write) original DX7 carts with the addition of an adaptor called the ADP1 ,so might be worth trying to find one

Oh, oh, one more thing... Did you try spraying them with cleaner. I use Radio Shack's cleaner & lubricant spray to revive noisy pots. For $10 US it's the best deal I've found yet for restoring

Hi Dave, I uploaded a photoshopped picture to the photos area of the group detailing the engineering specs for these Panasonic EWANF style slide pots. The album name is DX7 and DX27 Volume and Data

Hi, Do you have a card ? I don't have one inserted, so somebody sugested that I should get one , insert it and play with the protect switch. You can try this, maybe it will work, I have no access to

Just a long overdue follow-up here. My DX-7 works great with the Grey Matter E installed. The trick was getting the right screws to clamp down on the board tight enough. Once secure, everything

What operating system do you use? In my case I use Linux and ?Simple Sysexxer program to send ?.syx files ?by computer to ?DX7FD ?through ?the midi

As I posted in another thread, my original DX is flaking out on me. BUT our sax player is selling me his DX-7IIFD for $300. The onboard voice library has been changed. I need some good Hammond-ish

My old trusty DX-7 is showing signs of wear. I'm in need of new volume and data entry faders. Does anyone know of a source for those parts? The volume I can deal with using an external control, but

I know this is an old post, but I'm now experiencing this same problem. Any updates or ideas here? Thank you very much. Jim
