Hi,
new to the octatrack and liking it a lot, only trouble is that the colours of the LED are hard to decipher for me even when I have two different colours underneath each other on the tracks…
I was wondering how other red-green colourblind users do find their way…
Also, I wonder if there could be a fix by adding some kind of tint to the leds?
Cannot believe how often music gear has given me trouble with this… 
thanks for posting this! I’ve felt the same way and have a hard time figuring out, which is the active track - not so much on the Octatrack, but more on the A4.
on the Octatrack, I look at the display to see which track number is highlighted.
it’d be nice if there could a firmware fix to change the color/contrast of the LEDs a bit more for each indication level.
This may sound ridiculous but I have found that those cheap paper, oldskool 3D glasses work great. The Red and Cyan work better than Red and Green for some reason.
It’s a similar idea to the blacklights suggested in the other thread. By closing one eye, the Red component of the light is accentuated. So, although they don’t fix your colour-blindness, they allow you to tell the difference between Red (or Amber) and Green with certainty.
They work for me anyway. I bought 10 for a couple of quid on eBay and use them whenever I need to distinguish between Red and Green, and don’t mind looking like an idiot while I do it!
Similar situation for me. The worst piece of gear I have for this is the Notron sequencer. The similar brightness levels kill me. For the OT, I found adjusting the ambient lighting in the studio to be a bit darker helps.
The better solution (only practical in a DIY situation) is using white, yellow, purple LEDs like I did on a Sequentix P3 years ago.
I don’t play live, so I can take the time to look closely to figure out the colors.
