Receiving MIDI from Alesis electronic drum kit

Eli, I am quite certain that the Alesis DM5 doesn't know which software it's sending midi to. Everything is fine. What does happen with midi triggers is that the note-on velocity appears for a very short time, and then goes back to zero - I reckon you have hooked a numberbox up directly to the input and are monitoring with your eyes?

Try it with print, and you should see the on-velocity for a very short time followed by the off-velocity of 0.

When looking at the midi implementation chart in the manual you'll also see that things that are supported are marked with a "0", while things that are NOT supported are marked with an X. This may have been the confusing bit reg. the note-on/off thing?

I haven't played with this model of drum kit. If it's hooked up via MIDI, however, it shouldn't be difficult to get it working with Max. If the manual isn't giving you the necessary information, I think you'd be best off to do a little investigating on your own, either via Max or other software. The first thing I'd do in Max would be to use something like this simple patch to see what's coming in:

As you hit a pad, you should see some messages show up in the Max window, preceded by labels. It's usually pretty easy from there to figure out what info is coming in from the physical MIDI controller.

Hope that helps, EH

I've got it working.

Hey man, I tried your patch, but i am getting no effect. I hooked a print up to the second output of notein and keep receiving number 127. The electronic pads are home made, piezo triggers inside of practice pads. Do you have any idea why they wouldn't have any velocity?

thanks
