Thanks for pointing to this tulamide. How do you get to find out about the new stuff you sometimes recommend?

It's magic! And just like every other magician I won't spoil the trick :P :mrgreen:

Sorry if this is too fundamental a question but I do like to understand stuff. At least where I think there's a chance for me!


Initially the wavetable reader code should only have one frequency input, but as I mentioned, to save cpu, I stripped out the ramp counter from all of them, and used a global one controlling all. Since the ramp is separate the wavetable reader still needs to know which frequency we are playing at, because it needs that information for the anti aliasing. So we have a freq input for the wavetable reader as well.

Ok thanks Adam I get it now; the Ramp Prim for the pitch and the ASM freq input for the anti-aliasing.

Many thanks for taking the time to explain what I was seeing! You didn't have to do that, so I really appreciate it.

Cheers
