This is a feature I would love to have! I was just thinking about the Vixen plug in and converting the files, but looks like I was beat to the punch. MIDI is perfect in my mind for sequencing. I wanted to ask for this feature in HLS, but I know Joe is a busy guy; the guilt would be too much…but now that the cat is out of the bag…. I would like to be able to “record” the MIDI input while listening to the song and viewing my preview channels light up in real time. Kind of a touchy-feely interface. FYI I have no interest in using MIDI for pixels, just the dimmable incandescent channels.  Too much?
