Thanks to Julien Bayle, we've had early access to customizing Push via the Python scripts. I've looked online to see if people are exchanging information about any changes they're making but have only found the thread here about the custom pad colors.
I recently got my Push in the mail and have currently been using Maschine for about two years. Needless to say I'm used to the way Maschine lays out scales: One pad up is a 5th, one pad down is a 4th.
I've set out to try and modify the InstrumentComponent.py to add this missing scale layout to the Push. I haven't had much success and am looking for collaborators.
