No, most cult synth from Dave Smith I know and one of my friends has got
a lot of them, are analog, I guess even the samplers have analog
filters, so perhaps all synth I know are analog synth.

Many musicians just use a keyboard amp, they don't use computers or do
recordings at home.
Should they pay for professional converters that convert the analog
sound to digital, while they don't need them?

If you ever would have used a mixing console, such as the Neve, you
would be aware that they can make the sound better.

ADAT can do 48KHz, 96KHz and 192KHz. Nobody will use 44.1KHz for
pro-audio, so that wouldn't cause an issue.

This could be solved, but OTOH the ADA8000 I own doesn't cost much, but
it only can do 48KHz and perhaps the sound quality is limited, I can't
hear this at home. OTOH even if the sound quality of the ADA8000 should
be bad, you can start with this device and replace it as soon as you get
the money. For a synth you need to pay for good converters directly.

Regarding to the needs of the OP. He starts a professional carrier, I
finished my some time ago ;). So I'll add another thing to reconsider.
He needs just on Microphone input, but it never can harm to have
additional inputs, in case one should get broken during a production.
