I have a HP Studio workstation and a portable Thinkpad workstation that I used for Cubase setup exactly the same way. A Samsung USB SSD T1 is where the actual data (projects and audio tracks) is recorded/stored so I can go between the two systems seamlessly. About a year and a half to two years ago prior to buying the Lenovo W540 Thinkpad I bought and tried to use a Surface Pro 3 i5 but it couldn’t quite cut it processor power wise (big projects with lots of plugins had stutter and dropouts. Win 8.1 and I believe this was Cubase 8. The SP3 fan noise was fairly loud when it kicked in and distracting. Needless to say I returned it a few days later and bought the Lenovo and it has been perfect. two SSDs, dock station with lots of ports, two monitors available, fast powerful Intel. That is the history.
Today I tried this: This is my “business” computer.
I have a Surface Pro 4 i5, 256GB, 8GB Ram and I added 128GB to the microSD slot Win10 Anniversary 64b and a Surface Docking station (little rectangle box). I decided to JUST install Cubase 8.5.2 on it and set up my RME UCX so I could playback mix and master wave files to analyze through headphones while traveling. I also installed Sonarworks VST Reference 3 headphone software for my Sennheiser headphones. Worked perfect. I should have stopped there but it worked so effortlessly that I decided to install and recreate my entire studio machine on the Surface and see if it could fair better than the Surface Pro 3, Windows 8.1, Cubase 8 system I’d tested earlier.
I installed iLok2/Lexicon Native Bundle Reverbs; Halion 5; Steve Slate Drums; DMG Equilibrium, Compassion, Limitless; Steinberg/Neve 5033 & 5034; Neosoul Rhodes; and more.
The Surface docking device adds four more USB3 ports to the one on the Surface itself so five which was just enough for eLicense, iLok, Wireless Mouse; Samsung SSD T1 and the RME UCX. The Dock also supplies powerto the Surface, Network port and two mini display port outputs. Also, the Surface comes with/supports Pen too. I forgot to try it with Cubase.
I loaded a 48k 32bfp project with about 40 audio tracks; SSD4 w/Blackbird loaded; Halion5 w/five instruments; NeoSoul EPiano; 7 Lexicon reverbs loaded but only two used; Steinberg reverb (forgot the name but French Church was loaded); twenty or so DMG Equilibrium (IIR/64/On mode) and fifteen or so Compassions; a Limitless and Sonarworks Ref3 in Linear mode. There was more there including mute and volume automation but you can get an idea as to the project size etc. I plugged in my 600 phones and pressed PLAY and it PLAYED. It amazed me.
This system in total is so small and light you could fit it in a coat with a few big pockets. The headphones you’d have to wear.
Almost forgot, you can wirelessly project Cubase (or anything) from the Surface to a HDMI monitor/TV with the “wireless display adaptor” ($50.US) accessory plugged into the TV.
Just thought I share this information.
Edit: Question - Can an Apple iPad “Pro” do this?
