Here's a great trick that was found by Matt Lee:
You can enjoy the same memory saving benefits as the Max Tune Up feature from the 2box DrumIt on the Alesis Strike!
The new SDSE version allows to use the Max Tune Up option with the Strike profile. It saves a lot of space for a small loss in sound quality. You can try different values to find what you prefer, increasing max tune will lower the sound quality and save more space.
