hardware that requires a 'handshake' before Sys Ex works?

Hi, i have a Zoom G9.2tt Guitar effects pedal and i have run into a problem.

the G9.2tt comes with a piece of software for PC and mac that lets you program the pedal easier and then send them across, you can also go ‘online’ and edit with changes being made to the pedal in real time.

my problem is, my G9.2tt will not send and receive midi SysEx data in its default on state. for it to send and receive SysEx data i have to pulg it into my computer via midi, open the software, and click ‘online’ then i close the software editor, and untill i  turn the pedal off it will send and receive mid sysex data, (monitored by midiox)

so i can send a message from midiox, and the pedal will change the settings to what i want.. but once i turn the pedal off, i have to repeat the conecting to PC before it will work again.

so the pedal requires a 'handhake message before it Sysex works, and im unable to monitor this message in midiox. when i route the softwares midi out through midiox, nothing is received in midi-ox, and also the pedal does not receive anthing. so maybe i am routing it incorectly. ive contacted zoom about what is required to get the pedal to work with Sysex, but after 5 emails they are of no help, as they do not understand what i am asking for (they are japanise)

in the ZOOM software i have the input port maple midi 2, and output maple midi 1

in midi ox:

      maple midi port 1—> SBlive Midi out

      SBlive midi IN–> Maple midi port 2

midi from the pedal is shown in the input winidow twice (so its being looped) but the output window once, and the software does not react to anything, and nothing sent from it will show in midi-ox

can anyone pick a fault in what im doing? anyone got some ideas?

thanks ,Levon

Maybe that handshake is sent via USB and not MIDI? Does their editor work OK without USB plugged in?

Edit: What’s Maple?

oh sorry, forgot to say.. it ONLY works via midi, USB is for asio audio only. so i dont have the USB plugged in.

Maple midi is the same as midiyoke, provides 4 virtual midi ports.

I dunno man… If you’ve got it routed correctly so that you can see for example midi notes being sent to the zoom, and you know a message is being sent… I figure maybe it’s sending some kind of non-standard bytes (0xF4, 0xF5, 0xF9, and 0xFD) so it is not recognised, or you are filtering it out, in your software.

i tried monitoring the output of TD drum studio, through midi-ox the same way, and it didnt work, so im thinking it is a problem with the way im routing in midi-ox, so i will have to have another play round with it.

or plug the midi out of my computer into another computer. grrr

sorry, long time since i posted, but i finally cracked it, had to get another midi interface and go out of my computer, and back in. so it sends a message that turns on midi sysex sending and receiving. :slight_smile: ill document it if anyone wants it who has a Zoom G9.2tt
