Looking at what is available for editing midi clips on the launchpad, i could not find exactly what i was after.
So i put some energy in improving the existing Python scripts for the launchpad and added a step sequencer in the mix !
As this wasn't enough I also added a Device Controller. I also Recently added an Instrument Controller aiming at replacing the user mode 1 (plain old user mode 1 is still available as sub mode of the user mode 1 button).
You can download the package there : http://motscousus.com/stuff/2011-07_Nov ... hpad95.zip
(Launchpad, S and Mini. MK2 RGB supported)http://motscousus.com/stuff/2015-12_Nov ... _Pro95.zip
The documentation is available at : http://motscousus.com/stuff/2011-07_Nov ... e_Scripts/
and here for the Pro : http://motscousus.com/stuff/2015-12_Nov ... e_Scripts/
for the coders out there, i try to maintain an up to date version of the code on github : https://github.com/hdavid/Launchpad95 https://github.com/hdavid/Launchpad_Pro95
