New ZX Beeper Engine: Squeeker Plus

Making an engine based on zilogat0r’s wonderful Squeeker engine (written in 2000, when the ZX beeper scene had almost died completely) has been on my to-do list for a long time. Now I’ve finally gotten around to it, adding per-tick channel-independant duty cycle control, a noise generator, and some percussion to the classic. Very pleased with this one! Demo tune + source code + download (includes an XM converter).
