LSDJ covers

covering Alice Deejay in LSDJ makes a lot of sense when you say both of their names out loud.

the '40' chain is still a placeholder but pretty much everything else is in place now

very happy with it now! thanks to artemis for teaching me how to use the wav synthesizer

another one: Stardust Speedway Bad Future!

i could've used the patcher tool to put the real vocal samples in, but the goofy little speech synthesis engine in stock LSDJ makes me feel like it's Metal Sonic itself telling you to 'get down' / 'hit it'

covered a song that's traditionally performed in the key of S with a neat trick to squeeze an extra not-quite-channel out of the PSG

the sneaky math in question: manually summing adjacent notes from the harmonic series, such that i could have something that approximated triads on a piano in the intro and guitar chords in the chorus without sacrificing the vocal melody or noise-channel percussion.

i did this by drawing a sin(2x)+sin(3x) into channel 3's wave data register for a perfect 5th, and sin(3x)+sin(4x) for a perfect 4th. (you can do sin(4x)+sin(5x) for a major 3rd, but it starts sounding too buzzy due to the low-resolution aliasing)



a technique like this was demonstrated a dozen years ago and called "the ghost channel" - this video shows someone adding square-waves to sine-waves by hand, but only at octave intervals
