   I have been working with my APC40 in preparation for Max4Live's release (whenever that will be). In the mean time I have stumbled up something that confused me. I plugged my APC40 in and fired up MidiOx, and noticed when going through the buttons/faders that the APC40 makes heavy use of both the Data1 and Data2 messages for each button combination. It does not seem like these are sysex/rtm/etc. messages, but multiple data inputs per CC/note on/note off events.

   My question is: How does max handle these types of data? Does midiin distinguish between the two? I have searched the forums/google/midi spec but have had no luck so far? Any help would be greatly appreciated.

   I myself just started using the APC40 in Max, I am starting to work with midi messages from simple midiin and ctlin objects. It is simple enough to figure out how to decode received messages from the APC in Max, but I am really curious how to send it messages as well, such as to access the clip launch buttons and be able to control them in a "Monome" type manner. Any suggestions as to how I could find out this sort of information?

   Ok, not a helpful response, but I can't contain myself:

   It's very easy to figure out how to control the LEDs. Max patches aplenty are provided.

   Where's the challenge in that!? haha.
   That Ohm looks quite impressive as well, I can't wait to test one out.

   This thing dominates. The faders and knobs are slightly weighted and feel superb. Each grid LED has 3 different colors with both solid and flashing modes. The messages were very easy to decode.

   Just to save some people a little time:

   Using the midiin/midiout objects:
   The top left button on the 5x8 clip control grid is 144 53 1, where 144-151 is the entire top horizontal row, 53-57 is the vertical row going down (the next row down in this case is 54), and 1 is the velocity. The bottom Clip Stop row is 52.

   The Velocities are as follows
   1 - Green
   2 - Green Flashing
   3 - Red
   4 - Red Flashing
   5 - Orange
   6 - Orange Flashing

   7-127 Are all green.

   If you got this far the rest should be simple to decode.
