Don't forget the octave shifter!

The octave shifter is way cool too!

With the second slider in use for transpositions, though, it's unavailable for this.

I guess we need another slider...?!?!

Brendan is working on something like that... or maybe Erik will include it in a future update.

Of course, as it stands now, a footpedal could be easily set up to do a 2-octave transposition making my puny 24 notes 48!

With 4 fully chromatic octaves on 1 hole, though, why would we need any more...?

I just posted another video demonstrating just that: 24 notes on a single hole. This is simply a proof of concept/demo video, but I hope it will inspire creative thinking about possible uses of this exciting new instrument.

The Lekholm DM48 MIDI harmonica's two "slider" buttons let users play up to 8 notes on a single hole. When you include bends, you can easily increase that to 16... or 24+ with some practice and programming.


My last video demonstrated how the DM48 can be used to play multiple instrument sounds on a single song, but it also utilized the sliders to increase note availability for the walking bass lines squeezing them all into convenient symmetrical patterns on the first 3 holes. Furthermore, by taking advantage of synthesizer logic algorithms, the five different keyboard chords were all triggered on a single hole! That left 8 holes free to solo in a Richter style tuning.
