Is this what all music forums are like?
Unfortunately, yes, quite often.
That partly explains why so few professional musicians use them. They're often able to stay out of things and get their information elsewhere, and many of them would rather avoid the day-to-day problem discussions that I and some others of us here get involved in. (Some of them have enough fights with their fellow band-members without going on-line for more.
)
It's a problem. I've wondered myself whether to get involved in things on this site, but I've tried to sort through one or two things I'd have ignored if they'd taken place elsewhere, because I've felt the battles were worth it here.
I think Ted Perlman may possibly have some genuine reasons for his grievances, but I really don't know. I think you're right to say his personal grievances aren't really relevant to this site, and he could say it once, maybe, but then let it drop.
Any of us may have genuine grievances. I do, in fact, with one of the world's largest record companies. But I'm not about to say which one, or why, and I don't visit company related forums and talk about it there, because it's neither relevant nor helpful to other people.
Ted, if you do have a genuine grievance then I can sympathise from my own experiences, and I'm sure many of us could. But I think you've got the message across as much as you can, and your comments are clearly becoming counter-productive, which tends to harm you rather than Arturia.
Speaking more generally, people can be a disappointment. I'm always especially pleased when a musician I admire turns out to be a nice person as well, or if an instrument-maker - individual or company - turns out to be decent and responsive. But I think it's a bonus when that happens. People are often problematic, and personal encounters are always a risk because of that. A long-time musician once said to me that he'd realised he'd wasted far too much time and energy nursing hurts and grievances instead of just getting on with making music. I think that's an experience all of us can learn from.
