Hi,
You connect the nord via USB to a computer and use the "Nord Sound Manager" software, that is available as a download on Nord's webiste.
Then you upload the program, using that software, from your keyboard to the computer.
You'll get a file, named after your program's name, and ending with the "ns2p" extension.
This file you upload here on the forum, using the "Full Editor" button that is next to the "Submit" button when you post a message, it gives you access to file upload.
Let's face it ... NS2 vs Jupiter80 :
NS2
1 program has 2 synth section
each synth section has 1 oscillator, unison modes (multi is nice) and knobs on the panel.
Jupiter 80
1 Program (is called a LiveSet) can have 4 sounds (including percussion, called "Tones"), a synth tone has 3 oscillators (called partials).
Effects have to be considered as well.
The "fight"
is more balanced than specs may suggest 'coz of Nord's ability to summurize things.
Jupiter 80 can selection PCM (samples) waveforms for each oscillator.
NS2, we can use samples (form Nord Sample Library), an layer organ / piano (with effects and "uncommon" settings).
You're right, this sound is sweet.
Also Cory Henry is a great board player imho.
Cheers,
F.
