i'm happy i made the buy decision... i see the DM48 as a complement, the same as a lot of people playing the acoustic and the midi version of an instrument, when i saw that i never think the player has to play one of them, i'm enjoying the player taking both. Practice in the night was the 1st thing i think before buy it, and i was right, that's a great advantage. Trying new tunings let you a real try, not an only in your mind try, also let you think (create) tunings for only one song, for example you play a song in C that also have two #, you can change the other 3 # in C next notes that give you the possibility of slide(s) ornament notes. You want to accompany a song that has 6 chords, you can make a tuning (bass-chord) that let you do the difficult parts combining the bass note chords with the three slides, so you haven't to do big precise jumps in the mouthpiece... you can write the tuning in musescore and introduce through a midi editing program in the DM48, so you haven't to stay tuning hole by hole in the digital chrome.
Change octaves, key transpose lets you for example accompaning a song that you are hearing in a different key that the one you know, till you learn the new key. Makes a practice understand of changes keys, that thing when we read in SlideMeister, if you play a Bb chrome like you play a C chrome in F, sounds in Eb.
Also that thing that are sounding adjacent holes let you know that your embouchure wasn't as watertight as you think, so DM48 is helping your chrome technique...
Also the DM48 take you out of your comfort zone, you have to start to learning the midi thing, and that thing really costs me a lot and more with the linux thing, going slowly but in the learning state, position that i always like a lot.
good health
