I'm sorry if I said something bad

My apologies......I had no such intentions ....
Sokratis,
there is nothing to apologize for; you are not only a musician, but also a sound engineer with first hand experience on the field and thus much more entitled and qualified to express your opinion compared with many others, self proclaimed experts.
I actually wish that you could post more, both here and on the Ketron Forum, because I, for one, value greatly your input.
