Instant Scratch Tempo on DDJ REV 7 needs to be 8, 16, and 50 percent change

Please update the tempo range to go up to 50 percent.  This is a feature that's important to scratch culture.  Scratch DJ's love the 'ultrapitch' feature from the 50 percent tempo range.  This would put the REV7 controller over the top for turntablists/portablists!
