Digital RGB (TTL) to VGA or HDMI

Former Member
Former Member over 11 years ago

Hi Ben! Great stuff I've seen you do in your videos. So maybe you can help with this.  I have a Roland S-550 Digital Sampler. I works great, via the monochrome output on the back of the unit. Yet, it is in grayscale. Is there a way to create a converter for the Digital RGB output so the sampler can be used with a VGA or HDMI video output?  The most important feature I would gain is being able to edit my data via a color interface, This would make it easy. Yet, I've found out that the Digital RGB output is using TTL. This is an old standard. Here's a link to an older schematic of a cable Roland made years ago.  http://www.chezrossi.net/s760/images/rgb25i.gifhttp://www.chezrossi.net/s760/images/rgb25i.gif   Here is another link to a newer model made by Roland, but still have the same video outputs.  
http://myweb.tiscali.co.uk/clouzeau/s760/monitor.htm All of the links show what would have been used.But, this stuff is discontinued. I don't want to throw it out because it's a great machine.  Thank you in advance for your help.

    Lloyd,

            I also found out that the TTL refresh rate is slower than VGA. I

    think its about 15.35 khz, though not sure.  Will the schematic you send me

    allow the TTL to be viewed on a VGA screen?  Please advise, thanks.

    From what I gathered it takes the TTL and converts it.

    That being said there are adapters available from china

    if you enter a search into www.amazon.com AND

    ebay too...  Truthfully I have never done this myself

    just relaying what I'd found in a quick search on the web.
