Mainbow and Roland V-440hd problem (black and white)

Hey everyone, new to the forums and pretty new to video synthesis.

I have come with a problem I am racking my brain over.

I have a Roland Edirol v-440hd mixer.
I also recently aquired a mainbow.

I have been attempting to get my mainbow to go into the sd inputs on my mixer.

However, the video sync seems way off and most of the time I get no color, or a color signal that isn’t correct at all. It seems like a weak signal.

I have tried all manners of things at this point.
Composite to bnc
Composite to s-video
Composite to Sima pro edit 3 composite input > composite out to bnc, s-video.
Composite out into a composite splitter, then composite to bnc, s-video.
And all manners of combinations of these things.

However if I plug my mainbow directly into composite in on my tv… color! As it’s supposed to be!

So I am -baffled-. No settings on either unit seem to get this color sync problem fixed. I’m waiting for a composite to vga and a composite to hdmi adapters to come in the mail but I honestly don’t have my bets that in will work.

Does -anyone- have a solution or know of this issue with the mainbow and roland mixers?

Tearing my hair out on this problem :upside_down_face:

Thanks in advance for any help you may have for meeee.

Roland mixers are pretty picky about video signals, way pickier than CRT televisions. So the Edirol doesn’t accept the sync signal from the Mainbow, but the TV is fine with it. I hate for the solution to be more gear, but other mixers have much more accommodating TBCs (such as the Videonics brand), and will likely be fine with the Mainbow signal.

The datavideo se500 can be found for pretty cheap online and has a rock solid tbc

Also if you find one without a psu that’s ok, they can be sourced really easily

I have a Mainbow and a Videonics MX-1 and can tell you that the color is not as is should be. It seems like a weaker muted version of what it should be like when I connect it to my CRT. Do you think a video distribution amp would help this situation?

So my understanding would be that the way the mx-1 processes the signal leads to just… a loss of color depth.

I am not sure if an amp would solve this issue. I know that it possibly could, I used a kramer composite amp for awhile as a workaround with the v440hd, but never tried it with the mx-1. I have replaced that gear with a v4-ex, which took the mainbow signal perfectly well (though some minor “lag” I noticed in comparison to the v440hd, which I believe is due to the internal processing done on the v4, especially as it converts an analog input into digital and being a bit of an older model now. Didn’t try this with the composite out on the v4ex though, so maybe that isn’t the case there.

You -could- use something like a color corrector /video enhancer (such as a sima pro/edit 3 or a Videonics PP-1) to enhance the color, though that would be more of a supplement and wouldn’t provide you with the same sort of signal you’d get directly from the mainbow. Still, would beef up that color regardless!

On a totally different side note: I hate the mx-1. Glad I sold mine. Great functionality, not a bad mixer, just way too sluggish for my liking.

check the manual, there is a setting in the menue of mx1 to boost chroma if the signal coming in isn’t really up to spec. worth trying out
