There are following channel amount limits (in Cubase Pro version):
- VCA - 32
- FX - 64
- Group - 256
It would be cool, if these limits could be lifted to unlimited or something ridiculously high. Group channel limit (256) is not really an issue for me personally at the moment (which could change in the future as my project template grows), but VCA and FX channel amount limits could definitely be lifted. Especially the VCA channel amount limit.
I know, that there is a workaround of using them sparingly or not at all , but it tends to be quite frustrating to be handicapped by these limitations. Not very pro for a version of Cubase Pro
P.S. - A related suggestion: FX and Group channels could be combined into an Aux channel, as their capabilities are nearly identical these days, but I guess that’s a topic for another Feature Request.
