Hi

I'm trying to get started using lv2 synths inside ardour. I have calf monosynth and reasonable sort of working. I use a2jmidid to get input from my usbkeyboard showing up in as jack midi. I then connected the usb keyboard to midi through in alsa tab in qjackctrl and midi through is bridged to jack midi. So I selected a2j as midi in put for the two synts. However they are both playing (makes sense, since they're both connected to the keyboard), but how can I handle them, for instance so that one only plays when I sit on the corresponding track?
