Technical Support is superb. First, I asked a pre-sales question. I received a reply in one hour. Pretty good!
Then, I purchased the player. I asked if they could add a feature I needed (play one item in the playlist and stop). They said they would add this in a future release. Wow.
Then, I noticed a problem. The player has the ability to read the ID3 tags from all files in a folder, and save them in the back end. This lets the player load instantly on the web page. But, I noticed it was not saving the download path for each file it imported. Entering them manually would be a big chore.
I asked the author for help on this. Within the hour they not only fixed the problem, but they sent me new plugin files which worked perfectly. This is outstanding customer support!
I used this player to replace another one I purchased on Envato called the Royal Audio Player. It was poorly documented and three attempts to contact the authors failed. It could read ID3 tags, but only in real time. So, the player would load tracks at the rate of one track/second. That was unbearably slow and resulted in a lot of visitor complaints.
In contrast, this player is well documented and blazingly fast. The work flow is logical: Create a player with whatever customizations you desire. Next, create playlists which can come from a variety of sources. Then, pick a player and a playlist and it gives you a shortcode. Embed this anywhere you want and you get a player.
If you are looking for an MP3 player for your site, I highly recommend this one. It has a long list of features and the support is top notch.
