Now I was pretty sure that it was bossible to map the midi keyboard with specimen, like having the bassdrum patch going to the C1 key only, for example. But in fact I can't remind how to do this. for the moment all the patchs of the four instances of specimen are playing from the same key C4. wierd... > Both seq24 and specimen have good LASH support as well, so you can save > the whole thing as one if it's complicated. I use the qjacktl patchbay, it is a wonderful tool, but there is something odd with it; it cannot distinguish the midi input of several instances of both specimen and zynaddsubfx. any help would be very kind.
