right, i got it going in max7.
firstly mlrv is written in max 5. so it should really be used in max5.
you need to install xsample in max7. to do this you:
find max7 in your applications folder, right click and show package contents.
modified xgroove installing instructions.
Installing [xgroove~]
Copy ‘xsample.mxo’ to:
Max5/Cycling '74/msp-externals/
now:
/Applications/Max.app/Contents/Resources/C74/extensions/msp
Copy ‘xsample-objectmappings.txt’ to:
Max5/Cycling '74/init/
now:
/Applications/Max.app/Contents/Resources/C74/init
Copy ‘xsample.help’ to:
Max5/Cycling '74/msp-help/
now:
/Applications/Max.app/Contents/Resources/C74/help
Restart Max5 (Max7)
also the setup file needed to be modified to fix for the new serialosc.maxpat which does not have an offset (for some reason the original serialosc.maxpat had an offset).
here my modified version:
modified_setup_mlrv
this link probably wont be up forever.
all I did was find the bpatcher with serialosc loaded and change the offsets to 0. 0.
if theres a serialosc.maxpat in the mlrv folder delete it. it’s now part of the max7 package.
i tested mlrv for all of about 30 seconds. it appears to work as it should.
