sorry guys, but Spotify streaming integration is working really poor with DJ pro.
skipping beats while loading and fading resulting in poor sound quality (even on hig end MacBookPro), no spotify off-line feature (I know about missing database interface from spotify, but this is “no go” regarding your aim to provide a professional DJ tool), slow sound+beat analysis…
Your idea is quite good, could become revolutionary, but actually it is not working for serious performances and professional set-ups; so don‘t use that wording for selling preposition and we won’t be disappointed.
Keep on rocking!
cheers,
Max
