Well, that's the HW. As with video, the 16-bits went on further than just mere hardware limits.

When we talk software mixing, STE maxed out CPU at 8 channels 50kHz, here's an example: http://yerzmyey.i-demo.pl/YERZMYEY-Octopush_ATARI_STe.mp3

Even plain 520 ST can do a lot on this YM chip.

Amiga 500 on the other had could a bit of this but only with 12kHz samples, and no volume control per channel, also those pesky filters.

Amiga 1200/4000 could do same - as per much faster CPU, but... they still left the old audio 8-bit chip in it :/

There's a package EPSS for the STE which allows using its 8 channel DMA as a software synth, at the same time as running other midi channels in Cubase. Makes for a very tidy DAW:

Other packages (DBE tracker?) allow the STE to play 32channel mods albeit not at 50Khz

All Amigas had a 6-bit volume control for each individual sound channel.

All Amigas except the A1000 could turn the high-pass filter off, and pretty much everything tended to do this.
