If you want ultimate fine control over how everything ‘sounds’, Cubase Pro is a great tool for the job. You get excellent tools for precision control over all things ‘audio engineering’.
Cubase can help you get really involved in VSTi plugin management (as well as external instruments/effects), and manipulate how they are played down to the micro-second. You can even hone in on very specific frequencies on a single sample and manipulate the data, and thus the ‘output’.
In contrast, Dorico just does his best to give you a ‘general interpretation’ of what a score says to play. It’s quick and easy to punch in a composition, and get some kind of fairly instant audio feedback.
Cubase is inherently DUMB. It can do almost anything to the sound of your project with amazing precision. It’s packed with tools to monitor and manipulate details. It has a pretty powerful ‘logical editor’ system that makes it fairly easy to ‘batch process’ otherwise monotonous and repetitive tasks in one simple blow.
The catch is…you have to ‘specifically’ tell it EXACTLY what you want it to do. You often must leave ‘musician mode’ and put your mind in ‘audio engineer’ gear. It’s extremely powerful, but Cubase can’t ‘think for you’. To get much use out of it, you have to be the BRAINS, analyze all of the possibilities, and ‘construct’ your own work flows, problems, and solutions.
While the Score editing aspects of Cubase do provide some ‘translation rules/logic’ capability, they are a bit different from those in Dorico. In several ways, Dorico’s ‘automatic score translating’ abilities are a little more ‘advanced/powerful’, with a great deal of thought in having it ‘just work’ without as much ‘direct user input’. The Cubase Score Editor hasn’t had much love/attention/development done to it in years. It still works, and is quite ‘flexible’, but in many ways Dorico has far surpassed it now.
Teaching Cubase to ‘translate’ traditional notation is more of an ‘open frame’ process. Cubase doesn’t ship with many ready made templates to get you started, so you have to invest time in crafting them yourself as you go. I.E. What do you want Cubase to do if it comes across a note with a dot over it? What should it do for a hair-pin drawn on the score? What should it do for an accent (>) over a note? You’ll get a nice ‘empty frame’ to provide the instructions, but YOU will have to fill it in. This can sometimes be the case for Dorico as well (through similar expression maps), but Dorico tends to come with a few more ‘ready made’ options available to just ‘plug and play’.
If you need to work with pure audio (recording/tracking) obviously Cubase is more than handy to have in your tool box. At present Dorcio can’t even host a simple stereo audio track without ‘hacking’ it in as a video attachment of some sort.
If you enjoy playing instruments and/or singing in realtime, recording this, and later worrying about arranging this stuff into Scores…then you will probably LOVE working in Cubase. It also has quite a few ‘song writing’ tools…theory helpers, chording and arp systems, and so much more.
People who craft music by simply DOING IT (rather than through composing it first) tend to get a LOT out of a tracking DAW. It’s an immersive and interacted approach to crafting music…in real time.
You just pick up an instrument and/or a mic, hit record, and pour your heart out. Later you can go back and ‘refine’ things into the presentation or performance format(s) you desire. It can be a refreshing and inspiring way to make music. Crap on the page doesn’t matter. Rules don’t matter. Theory doesn’t matter (at least not in the moment). If you want to vary the tempo just do it, it doesn’t matter. If you want to play in slight variations of an otherwise boring baseline or ostinato passage over many bars, just DO IT without worrying about how it might look on a printed page. If you get a bit off the click track (or don’t want a click track at all…just play it like you feel it), forget it and ‘move on’…keep playing, you can always go back and fix mistakes. You can ‘punch in/out’ on recording and fix things by just playing it again over the ‘mistake space’, or you can use tools to ‘edit the existing take’. For the most part…you just feel it, and DO IT in real time, then ‘play it back, think about it, and maybe fix/change it’ later. You can get in some really ‘creative modes’ where things ‘loop’ and build another part/track on each ‘cycle’. Have fun with it, and just ‘play in’ the different harmony or counter point parts as the thing cycles.
It can be a LOT of fun!
Cubase has plenty of tools to take all those ‘real time performance snippets’, and ‘tame them’ into the proper constraints for making ‘written notation’. I.E. Force things to a fixed tempo and time signature so it makes sense in written notation. Get rid of the real time ‘groove’ so it might notate things in straight 8ths, instead of a crazy variety of doted and flagged notes with weird rests everywhere. Translate hard playing to show ‘accents/dots/etc’ over the notes. Etc…
It does take TIME and practice to learn what they are, and how to use them though.
So, if you wish to get into the realms of very high-quality performance mock-ups, then go for it.
If you enjoy improv composition. Playing and recording yourself, jam sessions with friends, or piecing together songs from huge collections of ‘licks/ideas’, then a DAW like Cubase will bring hours of joy, and meaningful finished projects.
If you want to deep edit pure audio, or do any kind of recording/tracking, then go for it.
If you arrange to film, video, or games…you’ll adore Cubase. It’ll allow you to set cue points, and automatically stretch/shink passages tempos so you hit a cue right on time. You’ll be able to do things like ‘adjust the beat grid’ so that Cubase ‘adjusts the grid and changes values in the tempo track’ accordingly. I.E. Play something in that gradually slows down and speeds up over time. Later adjust the ‘grid’ so things will line up with the beat properly in ‘written notation’.
If you think you might want to get into stuff like pod-casting and having a lot of powerful tools at hand to mix and make that kind of content, it’ll become a very valuable tool in your arsenal.
If you’d like the tools to better polish and master your Dorico audio renderings for distribution/sharing, again, it can come in handy (and you might even like WaveLab instead, or in combination with Cubase).
If you don’t play or sing much (enjoy real time performing), don’t need any of that ‘audio engineering’ capability, and don’t anticipate devoting much time to working on your ‘audio engineering’ or ‘real time composer/song-writing’ chops, I dunno. It just depends. It might come in handy since it would potentially open your world to more ‘collaborative’ opportunities (swapping files and ideas with other Cubase users). Then again, it might just end up wasting space on your system until you eventually uninstall it to ‘make room’ for something else.
