Midi In Filtering

Jan 25 2010 | 3:05 am

Hello All,

I’m fairly new at this so…please be gentle. ;)

I would like to separate a stream of incoming midi data by channel number. I would then be able to tell messages on ch. 1 to take a different action then messages on ch. 2.

Here is what I have so far:

Midiin connected to midiparse. Would my next step be to create a conditional if / then / else statement? I have searched the help tutorials, but with little luck.

I assume if / then / else statements are written into objects. Is this correct?

Any help is greatly appreciated.

Use the last outlet of [midiparse] to control the routing of a [gate 2] and you’ll get one channel from each outlet.

midiselect might be useful as well, maybe not in your case, but as it’s new since 5.1 it’s worth mentioning it.

Bonjour ej,

while we’re on this topic, I’m actually playing with 14bits pichbend and discovered that midiselect only send the 7 MSB bits. No @xben attribute?

I solved this issue by connecting midiparse outlet 4 to a number field, then using the select object to filter. Kind of like a simple if, then, else…but without the if, then, else.

@Patrick midiselect is based on midiparse which is the reason why it doesn’t support 14 bits bending. I can add that too my list, but there’s no promise if/when this would happen.
