Called tech support. According to one person GS4 support Gigastudio was dropped in July, phone support goes till December.
So a press release was dated May 19th, 08 on KVR that it's for sale.
July 21 announced it will cease further development of Gigastudio while sale and support will continue through the end of the year. I guess support doesn't define bug fixes.
The phone tech support was lame at best. Very obnoxious as well. He could not verify when GS4 was released.
I'm going to assume they didn't sell very many units of GS4 so they can screw the few unfortunate. If I am not reimbursed I will write a letter to the attorney general of the state of the corporate headquarters.
I will only have nothing but criticism for anything bearing the Tascam name.
