There's a sense in which this isn't the most practical choice -- general purpose synths (software or hardware) and libraries available for most runtimes give you all the power you need to create the bleeps and bloops.
But there's also something good about old things and limited things being put to good use, and finding ways for creativity to thrive in constraints.
Here is a gift to you, I found this on the Internet Archive. it's a cassette dramataziation of Asteroids and Yar's Revenge. I'm not sure how many other people on earth would care fellow Atari-knower, but it's a wonderful little time capsule.

I actually have a 2600 with the cartridge and a midi modification which allows it to act as a synth proper. It's a very distinct sound, and on the break I can play some space invaders
There is also the Mssiah cartridge, it even has a MIDI IN. Totally sick cartdrige. I integrated my C64 into my multi-instrumental MIDI setup driven by Cubase on an Atari ST with this. :-)
Thank you very much for the lordly recognition with ‘they’. You know, "sync" in the context of electronic music hardware is understood as "midi sync" or "pulsed sync signal". How should I should sync the arp of this Atari cartdrige to the tempo and pulse of a song that also includes other instruments? If I can't, it is only usable as a stand-alone instrument, which is of course totally legitimate.
