Re: [Hydrogen-devel] [PATCH] MIDI-out feature

[<m.w...@gm...>]

hiho,
wow... great!!!
that sounds very good. i am not sure if we can implement this great feature into the 0.9.4 h2 version. it would be helpful to add an compiler option to activate/deactivate this feature in the sconstruct file. some people try to build binaries for windows and osx. and maybe other people under linux don't use alsa.
 
if i understand your patch right you can send
* note on messages from each instrument with the given instrument "midi in" note number
(eg. kick = midi note number 65) and you can also change this number with the new
combobox in instrument properties.
* note on velocity is the same than the velocity you have edit in the NotePropertiesRuler.
* midi channel can customised for each instrument with the second new combobox in instrument properties?

what is with note off msgs? in moment h2 allows to edit the note length using the right mouse button + move mouse by clicking on an existing note.

greetings wolke
