[DSP-10] Audio filters question

Sat, 15 Mar 2003 18:30:22 +0100

Lyle,

Thanks a lot for the explanation. I'll try that tonight.

I'm using stereo connector with my K1 so that will not be a problem.

I also had a problem with UHFA reporting error. At that time I was using
EZFAST for loading  UHF3.EXE to Ezkit (I had to use the L parameter to lower
the comm speed). Another problem was that Scrl-Alt-F4 didn't work so I had
to turn off the PC when I wanted to exit UHFA.

Now I'm using EZLD and UHFA doesn't report any errors (and Scrl-Alt-F4 now
works).
