I have been keeping an eye on Keith McMillen's Smart Fabric Tech and midi over the past 2-3 years.He has gone through a number of kickstarter campaigns and most recently released a drum pad.https://www.keithmcmillen.com/products/boppad/Pearl Drums has also gotten into this and is releasing a Mallet station using the Smart Fabric sensorshttp://pearldrum.com/products/kits/electronics/malletstation/So maybe in the next couple years or so we'll start seeing a wider range of sizes or maybe even kits
