I´m thinking about...
First: One of my work is Cover Band for Wedding too... I used to take my Working horse - the Yamaha PSR-SX900 - with me,
because it has ALL the requested sounds for everything.
No premium Clone Wheel? No Piano Hammer Touch feeling under my hands? No cool red key to show? - Well - no problem!
This is a Job and it’s not me to be satisfied, but the newlyweds and their guests. Don´t ask for, what you want...
(maybe not once again this"Il ragazzo della Via Gluck"- but to be honest - I like it...)
To the Nord Samples:
You can find hundreds of good (Synth and other) Sounds on the Nord Library. You can even find (charged) Sound-Packs in addition.
If you want a special Sound, you´ll surely find it anywhere. (i.e. patchfoundry.com, synthonia.com or narfsounds.com a.s.o.)
The very special thing on the Nord Key is the Sampling Option, that let you get every Sound YOU like,
as far as you have the original Instrument to be sampled on hand - I APPRECIATE THIS...
...BUT a Sound is a very personal thing and you need to tweak it to get it your way.
For sure you can find a ready-to-use Patch somehow, but on a Nord Electro are always some settings to do:
Attack, Release and the Effects need to be set to YOUR way and there is the EQ in addition, what shapes the Sound too.
I would say, that it is necessary to put yourself in front of the board and program YOUR patches.
But this must not be a bad thing! The Sample Editor, Program Manager (free of charge) and the simple interface at the Nord Electro makes fun.
In summary:
I think the Nord Electro is everything but not a Rompler with all Sounds ready to go inside.
If you want most of the popular Sounds onhand, I would take a MODX or FANTOM.
For the Nord Electro, there is some work to do. But I love the Nord Concept
that let me change the Sounds in my key and form my own Instrument-Database.
It gives my Nord a very personal Note and let me have only MY requested Sounds on Stage.
My Nord with my Samples inside is like no other...
So I´m not sure, if you can get lucky with the Electro instead of the Juno.
If you have been happy with the Juno-Di, you could thing also about a Juno-D or even a FANTOM-06.
These keys will surely offer lots of uptodate Top100-Sounds ready out of the box.
the Electro will surely nedd some "love&understandings"...
