I tried Redux in Reaper, but there is still the issue, that the computer keyboard is not working in the editor.
@taktik mentioned once that it is a Ardour or Reaper problem. But it does not seem to have high priority, so I keep using Renoise (and maybe also would if Redux would work in Reaper)
I have the feeling that the community is very active. Many people participated on Mutant Breaks and there have been really many Renoise related youtube videos recently. I also like the community here. I took a look in the KVR Bitwig forum where people post their tracks. In contrast to here there are almost no people commenting on other tracks.
