For a MIDI Controller:
The first thing you have to do when you want to use a MIDI controller to toggle between kits in Sensory Percussion is enable your MIDI controller in Sensory Percussion's I/O panel. To do this, first plugin your MIDI device, and open the I/O window .
Next select your device's name in the Active MIDI inputs list. If you can't see your device in the I/O window, then you probably need to enable it on your computer. Follow these steps to get your machine to recognize your device.
Next select the controllers tab and then click on Ext.Auto and choose MIDI Input from the drop down menu after you have clicked the "+".
In the controller that appears click "learn" and manipulate a parameter on your physical device. You will notice that the number box labeled "note value" now displays a number value that corresponds to that parameter of your MIDI device.
It is a good idea to use a button for kit switching rather than a knob or fader because buttons allow you to toggle one-by-one or jump to an exact kit, rather than continuously scrolling through values, which risks over or under shooting your destination kit.
Now you can drag that controller's assignment to the kit manager's left or right arrows, or to a specific kit number.
Here is a template Set for using a MIDI controller for switching kits (all you have to do is enable your controller in the I/O panel, and then learn the parameters of the device)
For your computer keyboard:
Select the controllers tab and then click on Ext.Auto and choose Keyboard Input. Select learn and then press any alpha-numeric on your keyboard. Now drag that controller's assignment to the kit manager's left or right arrows, or to a precise kit number.
Here's a template where the "j" and "k" keys toggle left and right in the set.
