I love Arturia's V Collection 4 -- with the Sound Map!
I have the new V Collection 5, and love it too - but the V Collection 4 has the Sound Map, one of my FAVORITE FEATURES.
In case you don't know what that is, it's like a map showing all the different settings for your chosen instrument mapped out in different locations on a map.
You choose some of the settings, and then you can pick a spot on the map that "melds / bends" the setttings together - giving you new settings based on how close or far the other map settings are.
The best part about the SOUND MAP is that it is FUN!!!
The Sound Map lets you change and / or morph sounds that you really like into new sounds.
So, even though I LOVE the new V Arturia Collection 5, I will never unnstall my V Collection 4 instruments - the Sound Map just makes them TOO MUCH FUN!!!
