[LAD] [LAU][ANN][MOD] mod-host supports MIDI controllers

Hello LAD, LAU. I've pushed a new branch of the mod-host<https://github.com/portalmod/mod-host>(midi-control)ntrol), the code in this branch makes possible assign MIDI controllers to control any input parameter of the lv2 plugins. This is in development yet, but anyway I'm inviting you to try it as is and, if possible, help us reporting bugs or suggestions of improvements. Two new commands were added: map and unmap. The sintaxes are: map <effect_instance> <parameter_symbol> unmap <effect_instance> <parameter_symbol> After run the map command, just acts in the control that you wanna assign to (MIDI Learn). The feedback to user is very poor yet, so you won't receive a message saying if the mapping was well done. I hope you enjoy it. Regards, Crudo
