ZBMOD is probably the most complex ZX Spectrum 1-bit music routine I've written so far.  It mixes 3 channels of arbitrary-length PCM samples. So it's like the notorious SampleTracker used in some tracks by Mister Beep, but arguably with much improved sound.

Hey all! this account mostly serves as a secondary way of listening to my music, just in case you prefer this site over YouTube. uploads might be scarce though, since I don't have premium.
