An Amiga Sampler 30 Years Later

There was a magic moment for a few years around the end of the 1980s, when home computers were better than professional ones. That’s a mighty grand pronouncement, but it refers to the crop of 16-bit home computers that genuinely were far better than nearly all PCs at the time for multimedia tasks. You could plug a sampler cartridge into your Amiga and be in the dance charts in no time, something which sparked a boom in electronic music creativity. As retrocomputing interest has soared so have the prices of old hardware, and for those still making Amiga music that cart can now be outrageously expensive. it’s something [echolevel] has addressed, with an open-source recreation of an Amiga sampler.

As anyone who peered inside one back int he day will tell you, an Amiga sampler was a very simple device consisting of a commonly-available 8-bit A to D converter, a CMOS switch for right and left samples, and maybe an op-amp preamplifier. This is exactly what he’s produced, save fpr the CMOS switch as he points out that Amiga musicians use mono samples anyway. At its heart is an ADC0820 half-flash ADC chip, and the whole thing is realised on a very retro-looking through-hole PCB.

For a Hackaday scribe with a Technosound Turbo still sitting in a box somewhere it’s a real trip down memory lane. It was a moment of magic to for the first time be able to edit and manipulate audio on a computer, and we’re glad to see that something of those days still lives on. See it in action in the video below the break.
