Analog Night is a refill full of analog modeling sounds, "extracted" from a Yamaha AN1X.
Review: The AN1X is the best synth from Yamaha since the DX7 in my opinion. It can sound warm and fat but can sound digital at the same time. This Refill covers these aspects a lot. In fact Eric of ReasonFan decided to sell his original AN1X since he now has his very own Refill covering all these sounds!!! In short: these patches are very useful and have a very unique timbre. With this Refill you'll be able to use the AN1X's sounds in Reason.
