My first baby boy also used to say "heart beep" 40-some years ago!
I agree with zozee about the machine signals, but on my Ellisimo there is an option to turn the sounds off. The Janome might also have this as a setting. I haven't done it because although they're annoying, I need the "reminders".
I just wish I'd realized much sooner how much I would love to use an embroidery machine for quilting. This is a high end Baby Lock machine that I bought used from a dealer who had upgraded it with a couple of bonus packs. It has an on-board camera and the designs can be rotated in tiny increments to position them just right.
I also wish I'd known how much I'd love the Baby Lock before I bought the first (low-end) Brother embroidery machine and outgrew it in 2 months. I thought all I wanted it for was to make labels for my quilts, and maybe embellish an occasional t-shirt. It would be great if that's all I wanted it for. It does wonderful embroidery, but the Baby Lock does everything.
