oh well. td15 = very good. kahit td11.
td30 will still be lighter than bringing your acoustic kit
kung pang recording, td30 will offer you multitrack outputs.
td11 at td15 e stereo out lang pero ang workaround naman e gamitin yung midi output tapos use drum vst, mas flexible sa tunog yun pero syempre you need gear like a dedicated recording interface to minimize latency. suma total, mas mura pa rin tong option na to kesa td30.
if i can afford it, td30 talaga bibilin ko. its the closest feeling electronic drum to an acoustic kit. you'll never know what you're missing until you try it. go to tomlee hk, get the td30 there.
