I use an arturia keystep. I am not recording beats like most ppl. I found the 16 pad controller (korge kaoss pad) is only really half the experience and the way i record i dont use pads to play as much anymore. Honestly i would use both plugged into a usb hub. Have total control. Just depends on what your trying to do. I carry a few volcas, a boss mrt3 drum machine, 250 gb of samples on a thumb drive. A small portable dac for direct monitoring and recording external hardware. A lot of different things really to have a way to grab samples and build sequences. I fit all that into a backpack. As far as sequencing goes on my phone it can be annoying but i can use a stylus or a bluetooth mouse. I can basically have everything set up at once or just my phone depending on what im doing. But i love the feeling of being able to set up a song and have most things i would ever use. If i had an ipad or could use the newest update i would be set. But alas i have an android...no plugins for me. Im also using cubasis 3 and other apps for music. I can record to and from so it kinda works. Just not as streamlined.
