So I'm trying to set up an all in one home studio/workstation. I am wondering what device I need for my situation, be it a DAC (Digital Audio Converter) or a ADC (Audio Digital Converter) or an Audio Interface. Currently, I plug my MIDI piano into my MacBook Pro via USB to monitor (via the headphone jack) using ATH-M50 headphones and record in GarageBand (using GarageBand as a MIDI controller). I am going to be doing MIDI recording with my MIDI piano and then also I am going to be doing some podcast work (voice recording), but also I will be doing some listening to music. I want a device that I can do all of this with (monitor the recording + just listen to tracks). I am wanting to upgrade my listening experience with studio monitoring headphones and a DAC, but I also want to be able to record. I am pretty sure there is one device that can do all of this but after 50+ hours of research, I can't find what I'm looking for. Also if someone knows anything about Thunderbolt docks, I am trying to find one to use with this set up. I've done so much research that I'm at a loss. Please help!
