I just wanted to give you my feedback of testing out the Prime Go and Prime Engine over the last 20 days. I really like the idea of having an all incl. device so I had to try the Prime Go. Especially as I am more or less an ambitious hobby DJ.
So my conclusion: I will return the Prime Go and stay with Serato instead. Here is why:
No Auto-Gain Feature/No Cue-Gain feature on Prime Go. I have a several year old music library with a lot of different audio levels where MP3s came from all over the place (friends, internet, bought etc.). No Auto-Gain feature in combination with no adjusting on a cue level is just too much.
Prime Engine working (not working) with iTunes workflow. This is just horrible. If I added lets say 100 new songs in my library which led to 20 changed intelligent playlists the workflow from sorting it in iTunes over importing it to Prime Engine and than bringing it to the stick is sooooo frustrating. I simply do not have the time for it.
The time it takes to sync my music to a USB stick.
The beatgrid analysis is not as good as on Serato. 5 out of 10 song get analyzed wrong.
The hardware feels really good and the touch UX is great. But with those huge downsides I simply cannot switch from Serato to Prime.
Hope this will change in the future.
