The Korg M1 is probably the first Workstation. (4Mo Ram memory)
The Atari 1040St (green screen) was a poor computer with a floppy disk and 4Mo of ram memory.
1000 Mo = 1Go (octets)
Impossible to make an entire and complete song with just the internal memory of one or the other.
So I had to deal with a short memory. Each additional event can compromise the achievement until its completion.
For example, it may be necessary to play certain sounds or instruments directly live, while the cassette recorder does its job.
You have a certain possibility of saving your instruments ans songs in the Korg memory or in the Atari floppy disks,
but all is : just Midi events !

For greater ease of listening, the audio was recorded on cassette tape.
The editing possibilities were wide but limited, very limited.
We only load one song at a time, 8 tracks and memory remaining limited to 4MB for midi events.
Whatever we do!

I will try to tell you more on this subject, at your request.
A small example however. I found this track from 1998 and it's an opportunity for us to talk about these old techniques where everything wasn't as simple as it is today.
Analyze it knowing that the piece reflects how difficult playing piano live is for me.
Note that the quantize possibilities were otherworldly ! (Joke)

Personally, I find it amusing to see the number of events that I managed to make eat to these old things in this one song.
I also remember that I heavily abused the reverb.
Have fun.
