FL Studio

Lifetime upgrades. No other DAW has that. Pay once, get awesome new features as they're released for years to come. It's worth the price even for those who use other DAWs because of the sheer number of tools included from the vocoder and seriously overpowered audio editor with top notch noise removal, to the variety of highly configurable delays and distortions. Plus you get excellent MIDI and outboard gear support and this best-in-class music visualizer called ZGameEditor that easily compares with high quality After Effects templates while being far simpler and able to export any resolution at 60fps.

That all stands apart from the fact that FLStudio is a world class DAW. With its vector-based interface, it looks beautiful on massive displays or even tiny ones. And it still works across multiple monitors too. The mixer is gorgeous and can be stretched to fit full-screen for getting those levels just right. And that piano roll, I've never used a more responsive, accessible and capable one. It's probably the biggest reason I always return to FLStudio, everything about that piano roll is just fast.

On a personal note, I would prefer the channel section didn't exist at all. The song editor is now fully capable for arranging patterns and configuring the respective sound sources. The channel section seems out of place and in the way. This is just a personal qualm though.

Altogether, this is just an amazing piece of software at an unbelievable price. I purchased a license years ago and continue to get stunning new tools without fail.
