Additional programs I'll need?

I’m just wondering, If I wanted to professionally produce techno, how many other programs will I need besides ableton? I’ve noticed that a few tutorials use “sylenth1”, and I’m wondering how many other programs I’ll require to get the full range of sounds?

You can do quite a lot with just ableton. But a decent synth will help a lot.

Have you tried the ANA demo? Its designed for techno.

no, I haven’t. I will have to try that out! thanks!
