Bleeps and the like.

Sketches, experiments and examples.

MIDI song.

Fake POKEY acid.

POKEY has no low-pass filter. So no resonance, no cut-off, and no real acid sound. It’s just POKEY acid.

Recording: real hardware, a stock Atari 130 XE.
Tracker: Raster Music Tracker.
Visualization: Corroscope.

Wobbling POKEY.

This is not a cover of 'Moment of Stop’ by Dariusz 'Dhor’ Duma. Great tunes should be left as they are. But… It’s just my humble way to express my huge appreciation of Dhor’s innovative approach to POKEY sound design and composition. It has been inspiring me for years.

Prism [redux].

I’m just checking my brand new/old 130 XE. The tune 'Prism’ is pretty old (2016). However, it has been slightly rearranged and polished.
