Topic: please help with defining and mapping mpk mini

This topic is old and might contain outdated or incorrect information.

I have made a def and mapper for the akai mpk mini, but I am having one issue in regards to the velocity sensitivity of both the pads and keys.

The mpk has two settings for the pads, CC and Note on/off. The CC I have been able to make work perfectly, but the pads and keys both use a note on/off with another value for velocity which is recorded in chackl's definer tool

<button note="0x20" channel="1" name="pad 1 bank 1" />
<led note="0x20" channel="1" name="led pad 1 bank 1" />
<slider cc="0x05" channel="1" name="cc pad 1 bank 1" />

<button note="0x30" channel="0" name="key C" />

I have tried changing the "button note" to "sider cc" however this stops the control from being recognised.

this is the raw midi data for the same pad pressed 4 times (soft --> firm)

99 20 0D 00
89 20 7F 00
99 20 21 00
89 20 7F 00
99 20 36 00
89 20 7F 00
99 20 43 00
89 20 7F 00

Is there any way I can map or define the velocity sensitivity of the mpk when using <button/> ?


Also, there is a "program change" setting on the pads that only has a note on message, Is it possible to include this. The raw midi data is

button 1 --> C9 04 00 00
button 2 --> C9 05 00 00
button 3 --> C9 06 00 00
button 4 --> C9 07 00 00

This is from the wiki wrote :
If the button sends CC MIDI codes instead of note-on/note-off, you can use a <button> element with the following properties:
- cc: the MIDI cc
- value: the value of the MIDI cc


If the button does not send messages on pushed/released, but on on/off, you can use a <toggle> element with the following properties:
- note: the MIDI note
- inverted: (optional) set to "true" if the device sends note-off when activated and note-on when deactivated


raw data, pressed 4 times with increasing pressure

93 01 0A 00
83 01 7F 00
93 01 2B 00
83 01 7F 00
93 01 2D 00
83 01 7F 00
93 01 29 00
83 01 7F 00

this is what I have tried in the definition, all the same button

<button note="0x01" channel="3" name="P3 pad 1 bank 1" />
<button note="0x01" value="127" channel="3" name="P3 pad 1 bank 1" />
<button note="0x01" value="0x7F" channel="3" name="P3 pad 1 bank 1" />
<button cc="0x01" channel="3" name="P3 pad 1 bank 1" />
<button cc="0x01" value="127" channel="3" name="P3 pad 1 bank 1" />
<button cc="0x01" value="0x7F" channel="3" name="P3 pad 1 bank 1" />

can you please provide specific examples in the wiki of every element used
