1-bit

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.

Joie et tristesse

Testing my latest 1-bit sound driver. Beepertoy is a meta-engine, which supports a range of different 1-bit synthesis types. It can emulate the sound of popular engines like Tritone and Octode, perform complex wavetable synthesis, and more. Sadly, the complexity of this engine means there won't be an XM converter for it.

Beepertoy v0.1 test

Composed in musescore and rendered with 1tracker using the pytha engine.
Made and recorded a few months ago on real ZX Spectrum hardware. 

I'm posting it here now to announce the release today of my #dungeonsynth album, which contains this composition, with a very different rendition (DX7 synth), here it is: https://garvalf.bandcamp.com/track/alb-iser-valdersta-waltz
