If you plug them in together they will appear as 2 separate midi
devices, each using its own 16 midi channels from 1 to 16. If you set
up pd to use these 2 midi interfaces you will have channels 1 to 16 for
the first device and channel 17 to 32 for the second one. You can do
your merging inside pd then or if you favor to do so use software
outside pd.<br>

<div>Hi all.</div>
<div> </div>
<div>I would like to connect 2 Novation Launchpads to my computer (OS
X 10.4) to make a 128 out of two 64.</div>
<div> </div>
<div>The problem is: Launchpad sends midi info on channel 1 and
there's no way a user can change that (at least there's no info on
that in the programmer's reference manual). So, the two launchpads
would be indistinguishable.</div>
<div> </div>
<div>Does anyone know how to workaround the problem? I know that in
Max there's the [midiin] object that permits the user to select which
midi device to listen to. Is there anything similar in PD (even tho a
quick look at the Floss Midi Object list seems to suggest that there's
none) (btw, i got the [midiin] hint by the creator of the monopad,
which is a software useful to connect more than one launchpad in Max <a

</div>
<div> </div>
<div>Creating an aggregate device of the two launchpads in CoreMidi
could do the trick?</div>
<div> </div>
<div>I would try that myself but i own only one launchpad and I'm
scared of buying another and then discover there's no way to
distinguish between them. </div>

<div>Thanks for any help,</div>
