to be honest i thought that was a pretty nice melody there. there's ways to shape the sound more, like using pxtone's weird-and-powerful portamento feature, but it didn't even need that, it's a solid tune with character
thanks for sending in samples! :D you'll see more of them later... perhaps...!!
I agree with you about PxTone melodies. The lack of outlining within the grid can make clicking in the right spaces a little bit too thought-intensive. The flipside is that the misclick chaos really lends itself to interesting grooves when you're not worrying about pitch.
