Weird MIDI-problem with Cubsae SX: Only playing every other

petal · Post by **petal** » Mon Jul 19, 2004 9:42 am

I have hooked up a Roland Super JV-1080 (hardware synth) to a PC running Windows XP and Cubase SX 2, and when I try to send midi to the Roland synth through a Edirol USB-Midi box it is only playing every other note that I have programmed in Cubase!?
I can see that Cubase is sending the Midi-signal both in cubase, on the edirol midi-module and the Hardware-synth. So the signal is there but the synth is only playing half of the notes for some reason. Everything is working fine if I play the same midi-notes through a software synth.
And I have "installed" the midi port enabler in the Cubase Root directory.

Does anyone have any idea about what I might be doing wrong?

Ok - I have now tried to put another hardware-synth to the signal, and it is playing all the notes, so the problem lies with the ROland Super JV-synth.
Any ideas would still be appreciated.

Hmm - there was a "stack"-option that was set to 2 of 2 which I have now turned off, and everything is working as expected. All though I still don't know what that stack-option is for....!?

Anyways, sorry for taking up your time.

OK, but I can't say I've any particularly brilliant ones...

Are you using a 'proper' MIDI cable to connect to the external synth?

What happens if you go:

MIDI keyboard->MIDI cable->JV-1080 ?

When you play the notes on the keyboard, do they all sound?

Is there an issue with #voices/polyphony settings in the JV? (Is is in a monophonic mode and you're playing overlapping notes?)

Are all the notes on the same MIDI channel?

Is there an issue with keyboard range settings, or velocity settings on the JV? Any kind of MIDI filtering there at all?

(BTW - I used to own a JV-1080 myself - amazing box!)

edit: Damn! Simultaneous post!

(interrogates missing braincells...)
Hellfire - I've remembered something. Having that set means that you have two JV's stacked together - operating as a duble-sized JV-1080! I think that there might have been some proprietary cable needed to do this - three or four could be stcked together in this way.

Hi Royston

Thanks for helping me out, but I think I have managed to solve the problem, by fiddling with the JV-1080 settings. It was the stack-option which was set to 2 of 2 which I have now turned off and everything is working as expected now
