I have often tested Nord keyboards of all kinds in my local music store or on trade fares, but something always held me back, primarily the keyboard and the connection to the sound, especially with acoustic pianos. The reviews of the Nord Stage 4 sounded very positive, with physical drawbars and a keyboard that is easy to play. I thought now was the time to purchase the easily transportable 73 HA version. However, after four days, I decided to send the Stage back. The main reasons for me are:
1. The effect routing: It is not possible to control the volume of the piano or synth section before the effects; it is always post-FX, which means that you would also control the level of reverb or delay. This is a significant design flaw. What is needed is the standard signal flow Instrument -> Volume control -> FX. For example take an OB-6 with the expression pedal you can control the volume prior to the effect section, so that you can achieve nice fade in and out effects with the pedal, while still hearing the reverb or delay. Or a real Rhodes running through a volume pedal and then into the Amp. I wrote Nord tech support if they are planning to fix this anytime soon, but got no response yet.
2. The sound: I am sound purist, and being also researcher in the field of music and audio analysis, processing and synthesis, I have a trained and rather critical ear. I was first rehearsing the Stage through my RCF HD-10A to get a feel of how it sounds live. And then in my studio running it through a RME UCX and Focal Shape 65 Studio monitors. I compared it side by side with my other gear such as Roland HP 507, Roland RD-800, Rhodes Mk II, Crumar Mojo Classic, Crumar Mojo 61, Prophet 10, OB-6, Subsequent 37, and was pretty disappointed with the Nord Stage's sound quality, it falls short in terms of dynamics and warmth. The acoustic pianos sound rather static.
3. No song mode anymore.
4. Section volume fader replacing the encoder of Stage 3 are not practical since you'll have value jumps.
For some it might be the perfect keyboard, since it is portable and you have everything in the box, I think particularly for cover bands.
I am afraid I still have to carry more than one board :) Since I cannot handle the RD-800 alone, I would probably opt for a Crumar 7.
Danke an Thomann, dass ich den Nord Stage 4 ausprobieren durfte!
