This is one of those things we see from time to time, a massive price drop on hardware! The Novation Launchpad series is well known for being the link between you and Ableton Live. These controllers work exceptionally well with Live, though we suspect you could easily make use of them for any number of things.
Honestly, at this price, it doesn’t matter what you need it for. The benefits of having a controller like this around are enormous. You could set it up to trigger anything that can run via MIDI from lighting effects to you DAW. The special pricing is only good through August 31st, 2020.
If you are wondering why they price drop, we can assume that they are getting ready to release a new generation of this product line. That typically means huge savings on the current line. But it can also mean you might be investing in a product that is about to be replaced. And if you’re the type of person who always wants the latest, you should wait. There may be a new controller right around the corner.
