I had a CDN-90 for several years, and I'm not mcontent of selling! I did essey several DJs that machine live in their clubs instead of a Denon, Stanton, Pioneer, and all have incredible dtest Instability, he spends his time has changed BPM.

The CDN-88 (his little brother) is much more stable, but the instability of their BPM is a critical point of these machines. I personally use NDCs for-88 with three cots cratifs Hot Cues and effects. But the NSC-90 despite the updates is a failure.
