One more thing doctorawesomesauce , about those tablety-thingies... actually bought a surface Pro 3 a semester ago, for working and ofcause drawing n´ stuff. Ok I think its a real alternativ to the Ugee´s ur listet... (Ok the surface might be way kostier after all, but now am able to draw on the move as well). And gimp... yeah it´s like the real old photoshop. (Without mods) there are like no filters which are worth using. And no dynamic drawing what so ever , (so no use for a drawing-tablet). But still for things like shading and and image manipulation it´s totaly.... ok, I gues..
I've got the Surface Book with 16GB of RAM. It's....mehhhhh overall and costs too much. The portability is fantastic, however. I do like the 1080p camera.
Since my somewhat recent forays into being more serious about learning music (theory) and whatnot, here a few things that are pretty cool, in my opinion.
Ear training, singing training and all that good stuff : GNU Solfege It comes with a truckload of exercises and making your own isn't that hard, either. I use this mainly for ear training and I think I have made pretty good strides thanks to this thing.
Music notation: MuseScore If you don't wanna shell out a bunch of money-units for sibelius and co and want something that isn't totally clunktastic, this is a really good choice. It both functions as a notation device and as a player, but it has some minor weaknesses in the latter field. Crescendos and so forth are a bit weird to use and grace notes, too (Edit: for playback, they enter just fine). Note entry can also be a little bit awkward at first, but once the controls are in your muscles, this thing is really, really good. It has pretty much replaced Rosegarden for me, and I really enjoyed that one, too.
Digital Audio Workstation: LMMS Pretty much Fruity Loops, only for freeeeee. It is quite good, some of the prepackaged VSTs are a bit weird, though. I like it more than Ardour but probably because I'm the scrubbiest scrublord regarding music, ever. It seems like a really powerful package, and my lack of instruments is probably the biggest reason why I can't do much with this. It might even be better than LMMS, but I wouldn't know at this point in time.
Tracker: Milkytracker A honorable mention. It's an editor for a kind-of MIDI format, only it's sample based, you use your own samples and don't use a soundfont/midi set. This is what they made music with for computers like the Amiga 500 or PC games in the 90s/00s. Fun if you want a challenge and limit yourself to 4 or so channels, like back in the days to squeeze as much as you can out of it. Great for chiptunes, but not restricted to it.
Sight reading/piano practice: Pianobooster The reason why I felt compelled to post in this thread again right now. I just found this tool and I'm already loving it. It's a midi player that lets you play along any instrument/channel, generating the notes on the staff on the fly. It's like playing a vidyagaaaame. Fun, and useful...if you want to improve sight reading and piano playing, of course ^^
