Launchpad midi causes disconnect


#1

Hi All,

I am working with a Launchpad mini. I'm trying to send it simple midi notes to light up the pads. I've used 'rbrt/launchpad/matrix disp' for testing and it works great! I can light pads on the grid just fine.

I'd prefer to just send the device midi messages manually, so I can have a little more flexibility.

The trouble is - Whenever I start a patch that sends midi messages to the launchpad, the launchpad does not respond to any midi input. When I take the patch offline, the axoloti console reports 'disconnect request' and I have to restart everything manually. It will not reconnect until I pull the USB cord out, re-insert and restart the patcher.

Is there a secret to sending midi to the launchpad that doesn't lock everything up? rbrt's custom objects are communicating with it just fine. The midi implementation for the launchpad specifies "Launchpad uses a low-speed version of USB. A limitation of this is that it accepts a maximum of 400 messages per second."
Do I need to speedlimit the outgoing midi?

Thanks kindly
