It’s an interesting talking point.
If the Volcas were around when I first started showing in an interest in electronic music, I probably would have went with/been gifted one. In my local store, the only available synths around the £200-mark (aka a very reasonable limiting factor, what a parent/guardian would happily spend on an off-shoot of a pre-existing hobby) were a MicroKorg and a Novation K-Station and I went with the one that to me felt nicest in use and had more tangible controls.
There are quite a lot of influencing factors on what’s good for a beginner: there’s an obvious intersection between small size and reasonable cost that makes sense for a beginner. For many of us that have been in the hobby a long time, the budget/marketed-to-beginners gear was very different in the 90’s and early 00’s, so I understand the disconnect. It’s easy for us, with experience and hindsight to turn our noses up at low-cost, simple gear but it’s the travelled path for a reason.
Would reiterate that if we’re talking about electronic music gear for kids, then yeah, depending on age, parents dictate/influence the start of the journey, many have suggested that the wee Roland boxes would be fun for them for good reason. When it’s come to friends showing an interest (i.e. adults, disposable income, other musical experience, technical aptitude) then the beginner gear I’ve recommended when asked does differ slightly…but not by that much. A drummer friend is currently quite excited by my wee Volca Drum as a starting point to drum machines, electronic sounds…basically going to leave it with him for a spell but have also recommended that he at least considers the Model:Samples/Cycles, because knowing him and understanding him, I know he’ll love the relative knob-per-function and sequencer once he understands what a sequencer even is! Just saying there’s some truth in what you say too: although there isn’t one true perfect device for each beginner, nor is there a one-size-fits-all go-to, the best starting point can be any number of things depending on the beginner.
I think we can probably agree that it’s quite a good/exciting time to be a learner: lots of options and resources (even YouTube on it’s own, learning resources like Ableton’s browser-based tool, legal routes to sampling etc etc).
A ramble soz.
