"I’m using everything really. The thing about FL Studio is the workflow in it is so open ended. I love that people think of it like a toy. There are a bunch of professional producers that look at it as some kid’s toy, my first DAW. But, when you say to them, ‘Hey, have you ever seen this additive synth, Harmor?’ And they say, ‘Oh, I can do that in Massive.’ ‘Oh really?’ So I’ll show them drawing your own filters and spectral waiting of a phaser, mono gliding inside a monophonic chord, note data that’s not a note... It actually makes people that work in Logic and Ableton angry because you can do so much stuff in FL Studio that you can’t do in those two programs. It’s actually crazy! For example, in FL Studio you can take a kick drum or LFO and modulate the master clock. I mean, why you would want to, I don’t know. It’s so open ended that it’s like working with a modular synthesizer but in DAW form.

Honestly, in my humble opinion, FL Studio is the most open-ended, incredible DAW that has ever been made. I don’t know how you can top that. Those guys pay me nothing. In fact, I’m constantly giving them feature suggestions to tame it if you will. FL Studio is mind boggling awesome. I love what Image Line are doing and really believe in it!"

In this Instagram photo we can see bt using logic on his new temporary setup.

In an interview with MusicTech titled "Show Off Your Studio: BT's multi-rig synth utopia," BT mentions using Reason, stating:

"I use Reason for its incredible patchability and excellent virtual instruments, and Bitwig also gets a work out for some of my MPE instruments."
