You’ll get access to a granular engine with the option to load your samples and combine them with traditional oscillator sources.

  1. A word of caution:

    The Humble team are scammers. They sell expiring software licenses and unavailable keys. I am going through a situation where they denied me access to every item in a bundle I purchased after they said my keys expired without any warning and the software vendor (Magix) refused to do anything about it.

    Humble also refused a refund, and are now looking like they are reneging on a store credit.

    The price may be good so I can see buying it, but if you do, make sure you check and claim your licenses as soon as possible. And back them up too, just in case.

    • They are not scammers, and they don’t sell expiring software and unavailable keys. They partner with the companies providing the software in the bundles. They provide an expiration date/redeem by date on each and every item you purchase.

      Everything that happened is your fault, and yet here they are kindly offering you a refund in the form of store credit outside of their refund policy, and here you are telling the internet that they are scammers.

      The only take away from your comment is how good their customer support is, those filthy scammers.

      • Without being too long winded, this is not the first time this happened with them, just the worst. They have had game keys unavailable just as soon as I placed my order before, which is somewhat understandable with Steam, but not Magix. Also they did NOT have anything saying there was a key deadline in the case I mentioned and they have NOT provided credit as of yet, instead they have cut off communications.

        Do you work for them by chance?

        To Numanoid’s point: I somewhat agree, hence a word of caution rather than a total denouncement.

    • I am sorry for your experience. But I am 100% satisfied with their service, have bought from them many times now.

      One has to take into account that many Humble Bundles are for charity, and as such we must take a stance of “live and let live”

    Krotos Studio 3-month subscription is also available for free. IIRC the code in the check out is “unlock” (got it from some YT video, it worked), but you stil have to give them your credit card, so I passed on this one. Looks cool, but I’m not getting a subscription.

  3. I’m very happy with getting Concept 2 for just an Euro! Have been playing with it a couple days in FL Studio, and is100% stable. It is CPU hungry, but I expected that for a synth relying on samples.

    I have little interest in the other stuff, that costs more money. Who wants to download 51GB of SFX samples? Just getting the free 700 MB pack from the Krotos webpage will last me a long time.

    Can someone confirm that a single instance of Concept 2 can use as much as 60 % of the available CPU power? For example even the default patch is really CPU hungry.
