Control Kontakt, Reaktor, and NI Synths w/your computer keyboard
When using Kontakt, Reaktor, or the synths from Native Instruments (Massive, FM8, etc…) you don’t necessarily have to have a MIDI keyboard.
You can actually use your computer keyboard to play MIDI into these instruments. This is a great solution for quick auditioning or when using a small setup with a laptop.

Take a look at these 3 videos to see how. This option must be enabled in some of the plugins.
