Settings don't stay set in python 2: PortMidi call failed... PortMidi: `Bad pointer'

When I follow the example in the README, the lights flash on the K-board (both when I import kboard, and when I change a setting), and the settings appear to change, but when I exit python after making a change, I get an error, and the next time I open python and import kboard, I get the default settings - nothing is changed.

Is there some "save settings" call that's required or something?

Example:

In [1]: import kboard

Current KBoard Configuration:
...
 Velocity Curve:                lin
...

In [2]: kboard.setVelocityCurve('log')

Current KBoard Configuration:
...
 Velocity Curve:                log
...

In [3]: kboard.midi.quit()

In [4]: exit()
PortMidi call failed...
  PortMidi: `Bad pointer'
type ENTER...

$ ipython                

In [1]: import kboard

Current KBoard Configuration:

 Pressure Sensitivity:          100
 Tilt Sensitivity:              77

 Velocity Curve:                lin
 Return a Value...
   when Pressure Disabled:      No
    Disabled Pressure Value:    127
   when Tilt Disabled:          No

This kind of looks like a problem with pygame, really, because it works fine in python2, and I can't see how your code is different between versions, but I figured you may have hit this, and might know what's causing it.

question leds?

cool, how did you find the sysex?
Have you managed to light the leds programmatically? Different note/velocity values perhaps as for the qunexus keyboard?

thx.
