Your program/ web app is really cool! I don't actually own a dx7 nor a dx7II, however, I am trying to edit performance carts I want split keyboard patches, for use on the dexed vst AND Behringer Brains euro rack module. I tried making a performance cart but it looks like it references patches that are already on a physical dx7/dx7II. Is there a way to have it communicate with dexed? Or maybe reference a cart that is open in the librarian? Then ... hmm... I don't know. I'm new to these performance patches, I just want to make my own split patches.

I know that both dexed and brains will load carts that have split presets, works great! I would love to be able to make my own for those devices. Thanks for reading I found another that is similar that will play a note on the preset, that makes it easy to audition when you are creating custom carts, but not performance carts...

You're right that performance carts just reference voices/patches on the synth. I'm not aware that Dexed could play multiple patches at the same time, I suppose you could use multiple instances and some MIDI splitting trickery in your DAW to achieve that. However, performance carts are DX7II-only feature along with some extended patch parameters.

Thanks for reply Wait, dexed can't play two patches at the same time. However it can play a patch that has a split keyboard in it. Hmmm... From this site http://dxsysex.com/ I downloaded http://dxsysex.com/SYSEX_DX7/Guest/!Instruments.zip In there is !Instruments\Keyboard\Splits There are two .syx (cart) files that have split patches in them. Here they are. Splits.zip I load those into dexed they play and are split patches. I'm trying to be able to create my own. I may not be using the correct terminology here. What I do know is that I can load a one patch from one of those carts and it has two different sounds based on the notes played. For example from the split2dx.syx cart - Split #40 C3 and D3 are very different.

Your patches use key scaling as a hack to achieve a keyboard split effect. Split #40 uses OPs 1-3 for the left side and OPs 4-6 for the right side of the keyboard, set up in such way they overlap as little as possible (L depth cranked up to max for 1-3 and R depth cranked up to max for 4-6).

DX7II can actually play two full distinct 6 OP patches at the same time. So unfortunately, DX7II performances won't be of much use to you. You could of course manually create split patches, but you'd have to limit yourself to fewer OPs per split. Or you could just use two (or more) Dexeds.
