I would really like to do everything with my Nord Stage 4 without the need to use the Motif Rack, but it is the same problem as before. Samples are still not velocity sensitive in the NS4 and I don't know any commercial Preset Seller who really offers High Quality Programms for the Nord Stage.
I have to say that I am not convinced of the quality of for example certain websites who seem to be selling partly old NS3 Samples as "new" NS4 Samples. I don't want to offend nobody. So I don't want to name any concrete website. I just get a strange feeling if I see a demo video for some "brand new" NS4 sounds and the guy is using a Nord Stage 3...

There might be websites who offer High Quality. After a lot of searching until now I have only found one website with sounds which are without doubt High Quality which is narfsounds. His 80s sound set is very nice!

Maybe I am wrong and one has to spend more time to optimize the raw samples with the effects and the EQ of the NS4. On the other hand I remember a statement of the My Keys to Music Guy who said that a lot of the NS4 Synth Sounds are lacking High End and maybe also the right amount of Delay and or Reverb...
Here in the forum I have found some Diamonds like for example the "KurzPiano" an amazing EPiano Sound. Because I was looking for an EPiano Sound which can be used with Pitch Bend. But as I said EPianos are not the problem. The problem are convincing Lead Sounds (a really Kick Ass distorted Electric Guitar Sound would be also nice) and I guess that the NS4 would be capable to do them. I am not such a big tweaker. I can maybe add a little bit of delay are EQ to a sample, but that's it. And it is nice that Nord offers Signature NS4 Sound Banks of great artists, but a lot of those sounds seem to be rather exotic and psychedelic. It is just not what I am looking for. In other words: I don't need another Neo Soul EPiano or nice atmospheric string sounds or whatever. There is already more than enough amazing Epiano Sounds and let's say cinematic sounds. That is not the problem.
So is there maybe somewhere a collection of Lead Samples or NS4 Programm which I have overlooked? Thank you in advance. And just one more question. For people who really want to tweak and deep dive into Programm Parameters: Why is there no Desktop Editor for editing the various Parameters of Nord Stage Programms?
