As it stands, there are effects in Renoise that I wish had wet/dry controls but don’t (the filter and compressor in particular), and there are certainly VSTs with which I have the same issue. I’m proposing that all effects should have a way to control the balance of wet/dry coming from them that’s independent from the effect itself.
I’ve been wanting this for a while, but recently had an idea about a handy way to implement part of it, namely, how it could be controlled. As it stands, effects have the XF00 and XF01 commands to turn them off and on, respectively, and that leaves a whole 253 places for additional control. I propose that XF80-XFFF be used for such a wet/dry balance control as I’m describing (and automation for it would be fantastic as well), and that solution leaves XF00 and XF01 alone so as to not break backward-compatibility.
