Correction, Max for Live costs $200 extra. Ableton Suite costs more, as does owning both standalone Max and Max for Live, but you do not need the $400 Max to script Live with Max, you just need Max for Live. And given how much it brings to the table and how many community and built in devices you get for that, I would argue it's very reasonable compared to other pro audio software. (Mind you, not incredible like Reaper, Valhalla DSP or Klanghelm's prices, but very fair compared to many others)
They are high, I don't argue that. I don't think they are ridiculous, given the quality of the product and size of the market (it's not word processing...), the fact that they are independent, and they way they run their company (which, from what I've heard, is a very nice place to work). It is extremely stable with very very few bugs, and running an independent software company that way requires high margins. (I'm a software mergers and acquisitions consultant, so I get to talk to buyers about this all the time.) Personally, I'm happy to pay a premium to support the way the company is run, I don't think for a second they would be as hacker friendly if they got bought by one of the big PE fund owned media conglomerates.
But you're not wrong, they are pricy. If people are on a tight budget (and I spent many years being that musician 20 years ago) I would tell them to buy Reaper and either standalone Max ($8/mnth, cheaper for students) or use Pure Data (open source).
Can confirm. Quite a few pieces of expensive music software allow you to transfer ownership of licenses. I just bought a used Maschine+ hardware unit and the seller included a printout with confirmation of ownership for the software component along with the required serial numbers for the new owner (me).
