Light issue (hardware-pads)

[thebiz]

when i play a sequence on the spark (as standalone),
the lights on the hardware dont blink correctly
to the sequenzer.

sometimes the lights dont blink, sometimes they stay on
until the note plays again.

I'm not 100% sure but it might be a power issue it is recommended to use a plug as even if your usb is powered other things connected might be drawing power that the spark needs , if you are using a plug with spark then not sure
