I unzipped it and then imported it. I'll try importing the zip file as you did.
That worked OK - I cleaned the project and rebuilt it without any problems. I can't see why I was getting those errors previously, though.
Thanks for the help. I'll try it with my SD card tomorrow.

Glad we got that sorted.
So for the rest of you, don't extract these archived projects use the method described in my last comment!

I must say, I love the video, it is descriptive and fun to watch. Great effort!

I tried the C64 - software synth example, and thought about if the largest error came from jitter in the time-base or ripple in the rail. Check the rail with a Scope and you see!
I guess that you could improve the SNR+D alot in the Audio, just by buffering the PWM signal - feeding the buffer with it´s own low noise LDO. (16 bit ~ 96 dB ~ (1 / 100 000) V => 30uV maximum ripple on a 3.3 V rail )

Probably not the most confused programmer anymore on the XCORE forum.

I actually imitated the PWM code from the C64 project.
Well i am suspecting both. Altho i wont work on improving this method as it was never meant to be a way to get great quality audio from it. I need to etch me breakout board for a proper audio DAC chip that will get me audio up to 192Khz 24bit if i need it, as a bonus it also includes a audio ADC in it so i can input audio to my XC-2 then too. So i can try doing some real time audio effects (hmm an XC-2 autotune would be awsome!)
