For once, I have to stick up for Ralf. Simply put, it doesn't imply anything.
Just because there is an option for something on another OS doesn't mean that I think that feature should be in every piece of software on Linux. This isn't comparing Guitarix or Rakkarak to specific pieces of software, this is comparing the choices of software for a usage and variety of tools on Linux to those on Windows or Mac. Guitarix or Rakarrak are just examples of what exists on Linux, and while I don't use them, just because they can't do everything that hundreds of pieces of software on Mac or Windows do, doesn't mean they are incomplete. This is ESPECIALLY true given your own view of the product goals which you stated...
I like to let you know that we never have the goal to make a competition
to windows or other OS's. We just like to provide a OpenSource Tube
Your software only provides one specific piece to the selection of guitar FX software.
Just because I have an option of using a socket driver and socket sets doesn't mean that there is anything wrong with my combination wrenches. In the audio world this translates into, just because I have the option of using EQ-A instead of EQ-B it doesn't necessarily mean I think either is wrong. I can use LinuxDSP's Pultec EQ, instead of or with Harrison Console's built in EQ on Mixbus, or I could use one of a half dozen different other EQs instead of either, and depending on the material I will use multiple. But this level of choice still doesn't compare to the literally hundreds of EQs available on Windows or Mac, but they do what I need them to and I am perfectly happy with them.
You got really defensive against something that wasn't an attack on you or your software in my opinion. Personally I don't even use either pieces of software so I can't speak for how good or bad they are, but I read nothing in Ralf's responses that said they were bad at all. Just that they don't equate to the much larger selection of tools on other OSes.
