I should talk more about the SeqTrak and do a write up on it, as a way of helping me fathom it out a bit more. Pairing it up with a keyboard is worth while too.
Behringer are interesting, in how they mimic so many legendary machines, so cheaply, it’s often asked; how do they avoid being sued? I guess it’s all down to patten etc.
I'd be interested to know more about the SeqTrak. Maybe you could show how you put a tune together from scratch.
I'm sure Behringer are very careful and have good lawyers. My friend in the industry is not too impressed by them, but they will sell stuff if it's cheap and does the job. It may not be as robust as other brands. I saw they copied the Linndrum and Roger Linn says they didn't ask him for permission. The vintage kit can be crazy money, but people want those sounds.
The only thing I have from Behringer is a small mixer that was 2nd hand.
I shall rise to the challenge :-)
