This is also true when adjusting the parameter from your controller.To change the base key of the selected pad(s) / Sound slot(s) on your controller:1. Hold the PAD MODE button to enter Pad Mode.On the right display, the key indicated for pad 1 (in the bottom left corner) is the currentbase key.2. Press Button 5 (OCT-) / 6 (OCT+) to adjust the base key by octaves, or Button 7 (SEMI-) /8 (SEMI+) to adjust the base key by semitones.The new values are indicated for all pads on the right display.3. Release PAD MODE (or press it again if you pinned the mode).5.1.4 Using Choke GroupsWhen your pads are in Group mode, Choke groups allow you to build sets of “mutually exclu-sive” pads: A Choke group lets you force each newly triggered Sound to cancel out all otherSounds still playing — in other terms, these Sounds would never play together, the newerSound automatically “killing” the audio of the older one. This is a behavior you can find in vin-tage drum machines (typically used to “choke” the open hi-hat with the closed one), but alsoin monophonic synthesizers that are only capable of playing one note at a time.Within a Group, each pad can be assigned to one of eight Choke groups. When you assign apad to a Choke group, the pad may be set as a Master or Slave in the Choke group:▪ If the pad is set to Master (default setting) it will kill the Sounds of other pads in the sameChoke group.▪ If the pad is set to Slave it won’t kill any other pad of the Choke group — but be killed bypads set to Master within the same group.You may set more than one pad as Master or Slave within the same group.Choke groups affect not only the notes you play on the pads and the notes triggered bythe Patterns, but also the MIDI notes controlling your Sounds.You can select multiple Sounds and quickly assign them all to a particular Choke groupat once!Playing on the ControllerAdjusting the PadsMASCHINE - Manual - 233
