I have my setup configured where I use a Launchpad (the original large one) to control the St. Anne organ stops, pistons and other controls. I also have one of the Launchpad buttons set up as a general cancel. I recently made some changes to my win 7 setup. I replaced my HDD with an SSD and then did a clean install of win 10. Since then, at times, when I use a piston that changes many stops or hit the general cancel, some of the Launchpad lights do not go out. I have it setup so that the Launchpad lights are full on or full off. The stops cancel on the computer but the lights don't go out. In order to get the lights to shut off I have to hit the button that's lit twice. The first press turns the stop back on and the second shuts off the stop and the light on the Lauchpad for that stop. I then have to repeat the procedure for any other stop lights that stayed on. I have my Launchpad connected directly a USB port directly on the PC. Everything is directly connected to the PC. Keyboard, Mouse, MIDI interface, Hauptwerk Key and touchscreen are all connected directly to the PC. Any ideas? Thanks.
I, and I think others, have found that the Launchpad needs to be connected to the computer via a powered USB hub rather than being connected directly to the computer. If you have one available, you might like to try this.
Good luck,
Peter
