Midi Buffer Lenght?

After 1 hour puzzeling and reading I finaly got my MIDI device working :)
(see my Wiki Page for the one I am using)

Was prety easy once you know I how…

I am only using MidiNote (devices) node, I connect the output to a stalone, so I can use a note as a seperate press off a button.

But I wondered what Buffer lenght means, standard it was set at 10, the Demo tonfilm made was also set at 10, so I keep it at 10, but I wonder what would happen if it would change it. (not that I will, because it works, but still)

Another Q:

Am I correct that I can only connect 64 buttons (notes) to 1 device, and than have to get another controller, and set that to a different channel?

Thnx already for the reply!! (and you should see the smile on my face!!)

no, midi is able to have 128 notes on each of the 16 channels. your keyboard might have less.

via “buffer length” you set the maximum number of incomming midi-messages that get queued for output in the patch. only one message per vvvv-frame will be output in the patch while within a frames timespan more than one message could arrive.

therefore:
set it to a high value (ie. 999) if you want to make sure that you receive every single midi-message arriving on your midi-interface. you will notice the patch still receiving messages after your stopped chaning values on your midi-device.

set it to a lower value if you want fast responses in the patch and don’t care about receiving all of the messages.

a value of 10 may be a good default for most situations where you don’t have to many midi-messages floating around but still want to make sure to receive all of them.

Thnx for both replies :)

I found in the manual of my midi-divice that I can get an extra for 64 more notes, but in my case every note equals a button, and I am not going to use more than 64, for now.

I am using midi only for on/off switches, so I doubt that I will have more than 10 input changes every frame.

@ Jorig, you explain everything so well, are you a teacher? ;)

oh. thanks for the flowers…
