Re: [Hydrogen-devel] [PATCH] MIDI-out stubs for CoreMidi / PortMidi (Re: [PATCH] MIDI-out feature)
hi chris, 2 days ago i have wrote a mail about adapted variants of midi_out branch. this post was mostly addressed to michael keörner. but this was a ambiguity error from me! i thought the mido_out branch comes from him. also i wrote his name into the changeset 843 description. so i hope it's ok for you, and sorry about ambiguity error. greetings wolke -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H ___ Hydrogen-devel mailing list Hydrogen-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/hydrogen-devel

If I understand correctly, the sending of a note on event in your code starts in note_on() in sampler.cpp with the line that says Hydrogen::get_instance()->getMidiOutput()->handleQueueNote(note); In the process() function in that file, the notes are taken out of the queue around line 121 (if there are too many notes) and 135 (notes that have played for as long as they should). You could send the note off's from there I suppose? > > I'm thinking I need to maintain another queue of note off events, and > checking for those to trigger in hydrogen.cpp > audioEngine_process_playNotes(), or perhaps somewhere in > audioEngine_updateNoteQueue() and audioEngine_process().

I am working on an "evil scheme" here to reimplement most of the sequencing code in that file (in fact, last week I looked at the code for the first time in about a half year, and I'm going to code on it next week I hope). What I'm trying to say is that if you hack on that part of hydrogen.cpp it'll probably have to be worked over again if I get that thing to work that I'm working on. - Jakob Lund. > > As for setting up a branch, how do I go about it?

Hi Chris, i've invited you to our development platform and created the branch. You can checkout the branch with the following command: svn co http://svn.assembla.com/svn/hydrogen/midi_out hydrogen_midi_out - Sebastian Chris Mennie wrote: > I poked around for a few minutes and see more or less what needs to be > done to handle the note length.

Re: [Hydrogen-devel] [PATCH] MIDI-out stubs for CoreMidi / PortMidi (Re: [PATCH] MIDI-out feature)
I poked around for a few minutes and see more or less what needs to be done to handle the note length. Unfortunately it's not a five minute fix since from what I can tell notes are only queued up if they haven't reached the end of their sample (which makes perfect sense). I'm thinking I need to maintain another queue of note off events, and checking for those to trigger in hydrogen.cpp audioEngine_process_playNotes(), or perhaps somewhere in audioEngine_updateNoteQueue() and audioEngine_process(). I just need to find the time to explore a little more. As for setting up a branch, how do I go about it? I'm guessing there's a repository admin I need to get in touch with?

Re: [Hydrogen-devel] [PATCH] MIDI-out stubs for CoreMidi / PortMidi (Re: [PATCH] MIDI-out feature)
hey, take a look in note.h. and in DrumPatternEditor.cpp line 140 and 292. sampler.cpp at int Sampler::__render_note_no_resample and int Sampler::__render_note_resample will check notelenght for the note sample process. hope this will help you. in note.h you see also one for the moment more or less unused feature of hydrogen. the class NoteKey. this is a great feature i have used in my fx_and_sample_fun_branch. default current h2 set notekey to C. but sampler.cpp is ready to resample the sample with oter notekeys. i don't know if this features will used in 0.9.5 i hope that we implement my note_key notepropertiesruler from my branch which use the NoteKey class. but if we implement this notekey feature the midi note message change for each netekey. in my branch i have solve this problem by changing the keyboard layout. * classic layout plays the whole drumset and each key is an other instrument. * instrument layout plays only one instrument with other note_keys c d e f and so on. as gabriel i also think we create an extra branch for it, and you get write access to svn. greetings wolk > As for the note off messages, I wasn't aware of the note length feature > in Hydrogen.
