PhidSlot pattern that polls values from a human device interface, based on an indexed slot

superclass: Pattern

*new(slot, type, device, repeats)

slot index pointing to a slot like a button or an axis

type index pointing to the type of slot (see GeneralHID for a description of this)

device a GeneralHIDDevice, or an element from the GeneralHID.deviceList, which will then be opened by the pattern

repeats number of values to return (defaults to inf)

// example
// build the device list and start the event loop:
GeneralHID.buildDeviceList;
GeneralHID.startEventLoop;

// find an Impact game device and open it:
a = GeneralHID.open( GeneralHID.findBy( 1973 ) );
// inspect the capabilities of this device:
a.caps;
// boot the server
s.boot;
// simple example:
p = Pbind(
\degree, ( PhidSlot( 0, 3, a, inf )*12 ).round(1),
\dur, 0.25
).play;
p.stop;
// more complex example, showing multichannel expansion and sequences of slots:
p = Pbind(
\degree, ( PhidSlot( Pseq([[0,1],2,5],inf), 3, a, inf )*12 ).round(1),
\dur, 0.25
).play;
// the type argument can also be replaced by an Array or pattern.
p.stop;
// clean up: close the device and stop the eventloop
a.close;
GeneralHID.stopEventLoop;
