I have converted a Max patch I build into a Max for Live device as an exercise for learning M4L. The original patch is a monophonic step sequencer that I wrote about in Step Sequencer Built in MaxMSP. I ran into some difficulties converting the patch along the way. Although it worked perfectly in Live, for some reason it was causing Live to crash after saving. It was also not storing the values in the Live number boxes, drop-downs, and sliders. The problem went away when I went through the tedious process of recreating the patch rather than copying and pasting my original work. This is a little worrisome since the next conversion will not be so simple (Multitouch Rotary Dial and X-Y Granular Exploration). Here’s an audio example with a little reverb to give you an idea of what it does.
