BuzzDK

Someone wrote a guide and some kind words for this device:

To venezoid:
Sorry mate, don't know how to answer this.
Max for Live is not easy for beginners, there is too much to learn, but keep learning!
Cheers

Addition to my last comment:
This device is distributed unfreezed, which causes dependencies to not be included.

This seems to be a clone of the Map8 audio effect from the pack "Max for Live Essentials". It is simply copied to a Midi effect.
It should work fine with Live 11, but you may need to make sure that the patch can find some necessary files like a bpatcher and some javascripts and svg files.
Suggestion:
Get the Max for Live Essentials pack.
Open the demo set Map8 DEMO.
Try edit the Map8 device.
set up your Max search path in "Options - File Preferences":
- add a path to C:\Users\USERNAME\Documents\Max 8\Max for Live Devices. Select "Subfolders" (Windows path)
Open this patch for editing. Check the console for hints of any errors

No - i doesn't say a thing on my Windows PC. Seems the problem is in the vb.mi.plts~ object. Maybe it's compiled for a MAC?

Thanks for sharing! I'll give it a try :-)
