The Korg NTS-2 is way more than an Oscilloscope - it’s a Tuner, FFT Spectrum Analyzer and even a Wave Generator! On my modular eurorack system I take my oscilloscope / tuner for granted - and on my desktop synths I really needed a similar solution. I always need a tuner, I often want to see the shape of the audio or LFO modulation waves I'm using, I also often want to check the voltage outputs of certain CV signals - and with my semi-modulars - like the Moog Mother-32 or Grandmother synth, I could really use a secondary LFO for modulation - and I'm not always near my eurorack system for that.
The Korg NTS-2 Oscilloscope has become my perfect answer. It was a $229 kit (including a beautiful $45 hardcover book...) and does all of the above with loads of options.
In this video I'm just giving an overview of most of the features in case you're considering it and want a walkthrough before you buy.
Here's what's in the video:
0:00 - intro
1:07 - inputs/outputs
2:15 - controls
2:45 - modes
3:05 - Scope
6:00 - Wave Generator
9:20 - FFT / Spectrum
10:25 - Tuner
11:38 - Global Settings
12:10 - surprise.

Using an #oscillator is a great learning tool and a sound design tool - and the Korg NTS-2 not only gives you that, but so much more.
