XPianoRoll is a pure midi-editor and written as the gui part of a sequencer. A sequencer is not part of XPianoRoll and the communication between a sequencer and XPianoRoll has to be created on your own.
-
XPianoRoll uses nw.js for the editor. It's preferable to use the sdk version to see the commands exchanged between max and nw. Console can be opened by F12. nw.js can be downloaded from here: https://nwjs.io/
-
To open nwjs the [shell] object is needed: https://github.com/jeremybernstein/shell/releases/tag/1.0b3
-
For the tcp connection the saddam library is needed. Install it inside of Max.
Download the XPianoRoll folder to your Max library folder.
Open xpianoroll.maxpat and adjust the path to nw.js inside [p open_gui]
Tested with Max 8.2.0 on win10.
For a description and a list of available shortcuts click on the faces in the upper left corner of the editor.
