New clip library now live

Although the old clip browser was fun, and massive! it wasn't practical finding and auditioning the clips you want.
[h2]
The new clip browser adds:[/h2]

• Keyword based searching (Snare/Kick/Bass Music etc..) Genre is combined with Instrument (So Snare AND Bass Music will display only clips that have both categories, Snare AND Kicks will give you both instruments)
  
• Type in a search term, this applies on top of the keyword based filters
  
• Filter by user audio and internal library
  
• Filter by Loops and One-Shots
  
• Click on the open icon to open a clip (if the browser is opened inside an existing clip, this will set the existing clip to the selected new clip)
  
• Click on play icon to play clip, Loops will cue on the beat, One-shots play immediately.
  
• Click 'Browse' in the properties to open the clip library on any existing clip. You can then preview/audition and load the sound directly into the current clip. Great for changing drum sounds already programmed up for example.
  
• 
• User audio is now categorised as one shots vs loops on load
  
• User audio folder can be changed from the clip browser
