Carlo

I'd like to ask Cycling74 if there's a way to see incoming 14bits (double resolution, up to 16383, instead of 0-127) midi values through "midiin" or some other external in Max.

I tried, but midiin sees only the "less significant byte", not both data bytes (MSB and LSB).

I tried "bcf2000" from Jasch, but it recognizes only Rnpn values, not Control Change values.

No object ever will see more then seven bits, as that is all that can be sent over a midi wire. MSB and LSB means that somewhere values greater then 7 bits are broken up and sent in chunks of seven bits. This decoding and encoding is done for instance with high precision pitch bend that indeed with xbendin can be encoded. You can also make your own scheme with multiple controller numbers. You would need to take a look at bitwise operators.

I got the fact that I can see only 7 bits with "midiin".

Anyway, since some developments to midi protocol were announced at the various ICMCs over the past years (14bits midi values sent trough usb; midi data speed increased 4 times) how is it possible that max msp doesn't have a dedicated external to handle 14bits Control Change values?

Moreover I can't "pack" together two consecutive bytes of data to obtain a 14 bit value, because midiin doesn't see the MSB, but only the LSB. I just can't get the MSB value in any way.

May I ask someone to deliver a little patch to show me how to see 14bits Control Change data in some way? (leaving apart jasch's "bcf2000", which only handles Rnpn data).

I haven't tried with xbendin yet.

Thank you very much.

the BCF2000 doesn't transmit high precision pitchbend, it's a pity.

I had the same problem like you. Here's my solution for receive and 

transmit cc 14 from/to BCF-2000. It works well for me.

Hi Lorenzo,
thank you very much for your patch!
I'll try it out immediately.
All my best,

Impossible?

This is not true, you must do something wrong if you come to that

conclusion. midiin sees all, maybe you didn't set the bfc to send them...

Search the archives, recently there was the same discussion with posted

solutions. Btw I would use ctlin instead of midiin, much easier to deal

You can also use my St.DblCtlin from the St.ools collection. Its a

patch, you can open it and see how its done...
