You have the presets. There is only 50 of them. There are no other soundsets from that author in the shop. I wonder if KV331 gaurds you against making a duplicate purchase of soundsets.
I'd say so. FL is one of the most popular DAWs out there. There is n insane amount of demos downloaded weekly. It is a very deep DAW. They are far from ever going broke and wont be bought by another company. Unlike Reason they stopped developing instruments and decided to work on the DAW. I've seen people create stuff other than the usual EDM stuff.
As for Reason they've done very little improving the workflow but they crank out proprietary instruments. Some of their business decisions seem like desperation or managed by a group that is clueless about the market, Look at the direction they've taken from offering a suite for $250 to now a sub model and a significant price increase on upgrades.
Sweetwater was not about lower prices but service after the sale. A people get older they start selling for less responsibility. I wouldn't worry. If it regresses then those who made changes should be taken outside the city gate and stoned. (not with weed)
