Yes. Itās fantastic. The initial learning curve is rough, but the IDE and built-in help have improved a lot since I started a few years back. The nice thing is that it scales very quickly. Say you have a simple sine wave:
{SinOsc.ar(220)}.play;
So, that looks like a ton of syntax to create a single-channel sine wave. Now, my favorite aspect of SuperCollider is āmultichannel expansion,ā or a quick way to create numerous objects. If you modify the line with the [] multichannel syntax:
{SinOsc.ar([220, 330])}.play;
This will put a 220 Hz sine on the left channel and a 330 Hz sine on the right. You can load this up with as many channels as you please. Panning that may seem like a nightmare, but the Splay uGen will help situate each generator in the stereo field:
{Splay.ar(SinOsc.ar([220, 330, 440, 660, 880, 110]))}.play
That will give you a rich, wide additive wave. For reference, we are spawning six oscillators in one line of code. Once you learn more, you can use faster methods for populating all of the channel arguments, adding MIDI inputs, turning that one line into a reusable SynthDef, etc. Start simple 
Speaking of which, cmd+. is perhaps the most important key combo to learn while learning SuperCollider. It immediately kills all active synths. When learning SC, itās super easy to write something jarringly loud, so keep that key combo handy. When I start experimenting, I start with a
{WhiteNoise.ar()}.play
to test how loud things could be expected to get. This can save you from a traumatic headphone accident when changing uGens.
cmd+D is also great. It opens the help document for whatever uGen your cursor is currently on. If you have your cursor on āSinOscā, it will bring up the SinOsc docs. The help documents are interactive. You can modify and execute the examples as though they were in the main editor window.
I just bumped the SC tips thread: Supercollider tips, Q/A
Hereās an interactive homework assignment that I turned in early in grad school when learning how to generate patterns in SC: Supercollider tips, Q/A
Iām definitely buying a Norns once the page goes live.
Oh, one weird tip: Donāt buy The SuperCollider Book as your first stop. It was written a few SC versions ago, so a lot of the code is out-of-date. In particular, I had a lot of āfunā when trying to execute the Microsound chapter examples a few months back. One of the uGens used in every example was no longer in SC 3.8. Itās a great book to have eventually as you get more comfortable, but it will cause a lot of headaches for beginners.
