sysex question #412 (DX7 Editor)

[v8media]

I can see that there are many sysex questions so far. I don't know if mine can be combined into another thread, or if it's slightly different.

Anyhoo, got the nice Lemur on the iPad and I would love to use it to control all of the various settings on my old Yamaha TX7, which should be exactly the same to control as a DX7. I found the TouchOSC template from Missing Link (they sell a wireless midi device that speaks osc over wifi), and was starting to convert it to send straight midi sysex, but TouchOSC doesn't appear to do sysex yet.

So on to Lemur. Here are a couple example sysex strings from the TouchOSC template.
Envelope Generator Rate R1: 0xF0 0x43 0x10 0x00 105 x(99..0) 0xF7
Envelope Generator Rate R2: 0xF0 0x43 0x10 0x00 106 x(99..0) 0xF7

I've been attempting to paste various forms of this into the data field of a slider set to sysex, but it gets colored red and when I click away and click back, the pasted content isn't there any longer.

Could it be near that simple, or is this something that will be more complex than a straight duplication of the TouchOSC template?

Thanks, Ian

Been waiting so long for something like this, and finally have an iPad to run Lemur and TouchOSC on. Here's a glimpse from the far past of what I was contemplating creating for the Nintendo DS (with no programming skills): http://v8media.com/ds-idea. An obviously Lemur inspired idea. Can that really have been 6 years ago?

Hi
Sysex often generates lots of questions . . .

A few people have used TO patches for the sysex info needed, only minor edits are usually needed.

Unfortunately there is a bug/feature re Sysex in the standard MIDI Mapping panel and it does not work currently
You can however use Custom MIDI Mapping. It is not bidirectional but standard mapping could not be either

Create a Custom MIDI under your Fader and then use its Mapping panel for sysex.
Also the variable data format is different -instead of TO's x(0..127) Lemur would be x*127 for 0-127 range
Search the forum for some of the posts regarding TO and sysex - for additional discussions

Cheers

Figured a bit out for this. Added Custom MIDI to the faders, and the editor accepted this format: {0xF0, 0x43, 0x10, 0x00, 105, 99*x, 0xF7}

I'm using a physical midi merge box in order to have a keyboard and the iPad hooked up at the same time. I just tried the iPad Keyboard template, as well as the hardware keyboard, and both are able to control the DX7 (technically a TX7, but I think they're the same as far as midi control goes).

I don't know if I've done everything to be getting midi output working. It's an iRig MIDI, so in MIDI Targets I selected the iRig in the To: section. Is there anything else I should set up in the editor?

I might have to set up some more obvious stuff in my template to see if it's working or not. Maybe the first operator isn't used by the current sound I'm trying to control?

hi

im on search for an touch dx7 editor also. but i have no ipad. if so i would take this osc-patch:

for me (win7 on tablet-pc) i think about building a patch in reaktor to send osc. but i need a program that can translate osc to sysex.
