Are you hobbyst? Do you like to play with your good, bad or crazy ideas? Do you like to have your fun and pleasure spending your free time? Knowing, that possibilities are always far beyond your current skills - so there's always room to improve and use professional tools wherever you like?
Do this with Bitwig Studio.
Stable, fast, full of features to use and experiment with. My precious shiny toy :)
Also best choice for Linux.
Additionally i want to say on price. For Bitwig Studio you pay quite a price, but you have perpetual license for versions released in 1 year. There is always possibility to download and run that version! Taking into account how great and feature huge DAW it is - you should think about it as version which will be one of best between DAWs for years. Even when not upgraded. Then if you would like to buy upgrades for next period it's less than half of first price you paid.
