So, I've built myself a wonderful little wavetable synth which I've hooked into Ardour using Jack. I built it originally as a standalone and so didn't really think to include any syncronisation stuff. However, now that I'm using Ardour as a MIDI playback device, I'm finding that my patch doesn't receive a MIDI-off when I stop playback. I've since added a little panic button, but it would really be preferable to not have to switch to the patch every time I hit stop. I'm at a bit of a loss as to where to start, so I'm wondering if anyone has any experience with this or similar issues regarding pd-Ardour interaction.
