Yamaha RX 17. New mods
« on: September 20, 2008, 05:42:21 PM »

Bent a few of these in the past and usually just create a patch bay on the big chip nest to the heat sink, job's a good un. So I decided to try and do something different, so far I've found a nice synth tone output array that will pay in time with the pattern, a meaty distortion, an ear piercing hi end distortion, Envelope follower LED and 10 stable bends on the next big chip along from the heat sink. These do strange rhythmic things to the pattern that's playing, a bit less destructive than the bends on the usual chip, most interestingly of all, you can do really fucked up things by shorting pins on the two chips with each other. Got a lot more digging to do yet before I start, butI'll try and get some pictures posted up as soon as.

Understood. I've got a stockpile of half finished bits and pieces lying around too. Some of them i'm too scared to power up because they've been lying around open for a decades, and i'm worried they've broken in protest...

Finally a picture. Still not got round to modding this sucker yet, but should be doing it soon.

Blue text is the Envelope follower LED

Purple is the synth tone mode

The chips circled in red and yellow can produce a meaty distortion and and ear bleeding hi gain distortion respectively

Sounds rad. In case you're interested, here's a site which has a few rx17 mods. I assume you've seen it already though?

I'm looking forward to patchbaying mine up Smiley

Peas.
