Re: The pitch of the sound is strange. (NextBASIC "PLAY" statement)

Perhaps, before you buy a cable or change your display, you could run your test PLAY program without a display at timing 0? You may write your program in C:/nextzxos/autoexec.bas, so that it runs automatically on boot.

Re: The pitch of the sound is strange. (NextBASIC "PLAY" statement)

The default is "7". If I change this, it may not be displayed on my HD TV. Yes, I'm afraid this is true. HDMI timing seven has a master clock frequency of 27MHz. This is almost certainly why your note frequencies are not at concert pitch. These are the master clock frequencies for all eight video t...
