Double the Speed of a Rex Loop in Reason
Thursday, February 15th, 2007
For those times when your loops in Dr. Rex are twice as slow or twice as fast as your song, there is an easy way to slow down the loop or speed it up. In the sequencer view, select a group of notes and right click on one of them. Then select “Change events”. You will see an input that is labeled “Scale tempo”. If you want to double the speed, type 200% and then press ok. Otherwise, type 50%. You can experiment with this for interesting loop speed variations


If you don’t want your hi-hat track to sound mechanical and lifeless, then you need to vary your patterns. This can be done with a few different tricks. First, alter the note velocities to create accents as seen in the left image. A good starting point is accenting the first of every three or four hits. Make the velocity on these hits higher than all the other hits. Second, set the hi-hat’s volume envelope to the following settings (and as seen in the right image). Attack = 0, Decay = just above 0, Sustain = 0, Release = 0. Now you can automate the decay time to make the hi-hat hit shorter or longer. This emulates the sound of a hi-hat being closed tighter or looser.
