Something I have been meaning to do for a while was convert the MaxMSP instrument that I titled the Wavetable Glitch Machine (WTGM) into a Max for Live patch. The WTGM uses a TouchOSC interface running on an iPhone, iPod Touch, or iPad to explore samples using granular techniques as well as a virtual scrub dial with friction modeling. Visit the WTGM tag to read more and view a video of it in operation. I have renamed the instrument Grain Machine for the M4L version.

First I prepared the patch for transfer to M4L. This involved making sure that all of the interface objects were in the main patching window, reorganizing the sub-patchers, and cleaning up a variety of other things that I imagined might interfere with the process. Following that, all that was left was copying and pasting the patch into a Max Instrument, replacing some of the standard Max objects with M4L objects, and building a tidy little presentation mode.

Although I had to rework some of the logic and patch cords, the conversion went surprisingly fast. I expected to be working on this for weeks, but it only took me a matter of hours to get it into working order. There is still some fine tuning to be done, but all the necessary functionality is in place. Here’s an audio example I made with a simple breakbeat loaded into the Grain Machine.
