Two years ago I started my music path by getting into (e)drums (currently I have the Roland TD-17KVX). I love playing them, but of course drums are not the most versatile instrument and I want to complement that with something else... obviously keyboard/synth are most versatile choice and this is why I am here.
I've never played a keyboard before so I would like to learn how to do that a bit, but I never really liked the piano/keyboard sound as much. I always really liked the synth sound more. Generally I listen to a lot of music. I really like more modern indie (pop/rock) stuff and modern retro sound.
At the end of the day I am looking at something a bit versatile, but more synth than a keyboard. If it can emulate a digital piano decently well or can be used with software as a MIDI controller that should be all that I need for my keyboard/piano learning. So that should pretty much cover any synth. It does however maybe mean that I would rather go with a full sized keys first. I've beet watching and reading reviews and opinions for the past four days and I still can't make a decision. Budget is around 500€.
I think I have narrowed my choices to these three in the following order:
- Behringer DeepMind 6 (probably currently at the top of my list. The sounds aren't flooring me, but the full size keyboard is a plus and I have heard it sound awesome as well - just not always)
- Modal Argon8 (this is a bit of an unknown. Full size keyboard is nice, but not as many reviews out there. Not sure how it is for a beginner. It's a digital synth though, which I seem to prefer)
- Korg Minilogue XD (everyone's favourite first synth. Not really liking the smaller keyboard, but it does sound pretty good even for an analog synth

Notable other choices:
- Korg Wavestate (as people suggested it's probably a terrible choice for a beginner, but ultimately of all these I like the sounds of this the most. It really sounds superb)
- Yamaha MX49 V2 (It's the most hybrid of them all since it's more of a keyboard with some synth functionality. But this is also why I don't like it as much)
- ASM Hydrasynth Explorer (I can't really decide on this one. Smaller keys are not to my liking and the sound didn't really floor me)
What would be the best choice here?
