Merge information from two midi channels together

If it's okay to run Max in parallel with Ableton Live then it's no problem whatsoever. Your Max patch can receive MIDI information from different channels via a [midiin] object (e.g. to Max 1). You can catch everything that comes into this [midiin] object via a [midiparse] object, ignore the input channels and route it all back into [midiformat] with one fixed channel of your choosing. This [midiformat] then transmits the merged information back into a [midiout] object (e.g. from Max 1) and on the receiving end you just listen to this merged information at the fixed channel.

Drum pads outputs short notes.

How do you want to link velocity and position in timeline of recorded pad

notes to different midi track ?

Have many ... notes listed and just progress, next , next etc ?

or trigger notes which exist in same location using velocity

from pad track ?

How about length of notes ?

Both could be done using 2 m4l devices...

Ah yes @HZ37, I'll check out this option too. Would be to have it run internally in Ableton but since Ableton's API it's not really possible apparently. Perhaps if I'd work with two seperate M4L devices. One which send and one which receives.

Either way, having Max run seperatly is indeed an option. Thanks!

Hi,

I just made a few M4L patches which do the trick. I made two send M4L devices with 'notein' objects that get routed to one receive M4L device which edits the midi. The one added in this post is the receive patch.

Everything "kind of works" but sometimes I get stuck notes. Always at the end of a note. I guess some of the note off's aren't translated really well.

Does anyone know how to fix this?

ps. The number box in there is intented to choose the note's length. So far no good results.

You don't need 3 devices, only 2.

put this into Drum Pad midi track. it sends only note on velocities

if you activate input monitor in Drum Pad track,

you play notes in other track in real time. Otherwise output recorded ones.

place this device into track with long notes.

The long notes track needs no midi input from drum pad.

Received velocities trigger notes.

you can adjust length as usual in makenote.

Hi Source Audio,

Amazing. This works really great. I'm gonna look into attributes and how I can use them. Thanks!

Do you perhaps now of a way to implement a way to edit the drum pad's note length? In the version you made I think it doesn't translate 'note off' information and makes for longer notes than initially played.

Could you maybe explain me how I'm able to implement note off values into this version and alternatively explain me how I can adjust the midi's note lenght? Would be nice to be able to change midi length information from the pad's channel with a knob.

Thanks!

ps. I rebuilt the second patch you sent but I am mostly getting random notes. Must've done something wrong.

martin, I think you'd need a [zl rev] before the [makenote] there.

also, I believe you can skip the [> 0]

last screen shot was only idea how to block drum notes when no long notes are sustaining.

I did not test it at all. one also have to take care of timing between 2 tracks.

idea is to open the gate while note in long notes clip are on, and close it

when they are off.

but as Wetterberg spotted, one mistake was to list in wrong way.

better would be this. (with adjustable note length)

I am used to insert > 0, even that any number higher than 0 would turn gate on directly as well.

You did not explain in detail what you want to use from drum pad notes,

and also not from melody notes in initial post.

I did not expect that you want to use note off from drum pad (being so short),

only velocity and position, and also use last known long note pitch.

Like my first example.

Because that would allow all drum pad notes to produce

notes just as played.

Only note length would be set fixed/adjustable in makenote,

which could also be randomised ?

In case you want both note on and off from drum pad,

simplest is to use makenote again with repeatmode 1 set,

because that would allow to use drum rolls, or better say shorter notes

that note lengths that you might set with that knob you mention.

I think main decision here is to use long notes On/ Off status

or to play last known pitch ?
