Harmonica

I use this quite frequently, the Midnight Cowboy preset in particular. It goes well with a slippery approach to bends, and a refusal to acknowledge the missing notes, a la Howard Levy (Béla Fleck). It can get a bit strident, but nothing that can't be tamed with a filter downstream. It seems to have a limited palette of really good sounds, and even after noodling with the knobs myself, I only like and use three of them, but those three are great. Here's a track: https://mal-2.bandcamp.com/track/cactus-is-our-friend

Why only the left speaker sounds? Is this happening only to me?

Very Difficult but if you take your time you could get a "once upon a time in the west" sound with the cowboy preset, the right wah and vibrato automatation and a bit of blending und gliding, and some attac, release, reverb etc. adjustments and of course some extra fx ...its hard, i tried some hours but it worked very good at the end...

This sounds like a dancing monkey not a harmonica lol. Cool synth, would be better rebranded.
