Swingmaster is a device with one task, control the swing amount in the whole Live set.
Load up an instance of the device on any midi tracks where you want swing. Dial in the desired swing amount on any of the units and it will change on every device in your set. Add a new instance and it will immediately synchronize with the other instances in the set.
Sure, we can use the groove pool for midi clips playing in Live, but now we can control the swing for any midi coming through. External midi, sequencers, arpeggiators and clips.
