"Brave attempt at the Sanxion loader music from the C64 by Rob Hubbard.

Chip used - YM2149F.....

Lots of modulator abuse and tracking to get it where it is. I even almost managed to nail the DJ record scratch just before the chill melodic part kicks in 🤣

YM 300, a 4XVCF and a 4XVCA set up for amplitude control, additional filtering and mixing of the three sound channels. The filters give the AY/YM an almost SID character. Especially when you sweep them on a channel with the on chip modulator active.

Very tricky one to cover on the YM due to the limited sound palette of the chip. It's incredibly hard to do anything with a long melodic structure without it sounding square wave basic, as is the vanilla nature of the chip. With the filters and some creative use of the modulator tracking things you can work around this. Without the additional filters this would have been impossible to do without it sounding too cute or like a dogs dinner.

The set up with filters is basically how an Atari ST or ZX spectrum might have sounded back in the day if their sound chips had filters.

Not a bad attempt. Not as neat as the C64 original. As close as i could get for a bit of fun with what i'm using. If only the AY and YM could do PWM 🙂"
