Thanks Troy! I actually emailed Karen last night with some of the same questions! She pasted her answer to you in her response. It will be great if she gets a couple of her old tracks online!
I had tunes the other night with a fiddler friend and played the Rakes for him. He immediately noted the nice breath pulse. It’s funny I hadn’t consciously wroked on that effect, since I use something similar playing PA and flute. I’m more a flute that an accordion player, though I’ve been taking video lessons with Mirella Murray and see some improvement. Would love to see/hear any recordings of your approach to ITM on melodica! Too bad about the volume issue with the clavietta,
