Not seeing 56 inputs on new 1221 firmware, Atmega1284

[plasticbrain]

Hi,

I have an Atmega 1284 MD board with 56 inputs, (Minimal Kit)

I updated to new firmware:
megadrum1284_56_20171221

Now, in the LCD menu, it is saying 48 max inputs, and I can reduce, but not set any higher (to 56).

When I Get All from MDMfx, it shows the firmware version expected, but it reports CPU as the "644".
I examined the board, and it does physically have a Atmega1284 chip as expected.

I have tried using MDMfx to set inputs to 56; Send All; Save to slot; but if I reset the board, it comes up with max inputs = 18.

I double checked and reloaded the firmware bin file again, making sure to pick the 1284 file, in case I had chosen the wrong one.

In case somehow files were not labeled right, I tried the "644" bin file, but this fails immediately and doesn't perform the load. that's probably expected.
Note: I was using the CMD window mdfwupdate.exe to load. The first time I loaded, I couldn't get MDMfx to work, but the command line EXE did.

So - is there an issue with this firmware version? Should I try another older version perhaps?
I upgraded from a very old 2014 version.

If it is stuck at 48 max inputs, which inputs get disabled? is it the highest numbered Aux inputs ?

Technically, I only need 37 inputs - we're setting up a 3-octave xylophone.
But I did my wiring expecting to have access to all the inputs... So I would have to move something if I can't get all 56 working.

Getting excited about our build.. finally just got all keys wired up, and ready to start configuring the notes.

I'll check and fix it if needed.

Please upgrade to the latest firmware version - 20180121.

Yes!
your firmware update today did the trick!
It's back to 56 inputs now.

Thanks for your amazing support.
We now have all 37 xylo keys firing, for the full 3 octaves, and they are all making noises of the right pitch.

Now, to tune the settings for sensitivity and crosstalk!

I would like to build up a xylophone-like MIDI controller.
Would you please tell us how to set up the midi map via "megadrum manager" or others?
