PCM90 and sysex
Now I need to send data requests to the PCM to display the loaded program’s state.
Despite many efforts, I can’t do this, I always got ‘sysex data error…” on the PCM LCD.
If anyone succeed in such a task, please give me a hand, I really can’t figure what”s wrong in the messages I send to the PCM.
I know it is quite off topic for a max’s forum, but I think some people smarter than me already tried to master this PCM.
Thanks a lot

Although I probably can’t offer any more expertise than you have already, this would be useful for me and my clients, I’m interested in the process, and happy to help test or whatever else an end-user could do.
Best of luck pushing ahead,

thanks for your concern, it will help me to keep searching.

Post a patch, and a reference to the sysex documentation of the PCM…
A midi monitor, which would allow you to verify which bytes you sent
F0 You need to know the basics of Midi and Sysex… FE

thanks for your help
attached is a patcher with everything I tried until now, what works and what doesn’t.
BTW, yes I did understood your joke, but why do you set a F0 at the end of sysex instead of F7 ?

Ok, I finaly found the “rosetta stone” and now I can send data requests to my PCM.
“let’s make it so cryptic that no one will ever make a midi editor”
now I come back to you dear friends to ask for a wise advice:
What is the best format to handle complex sysex
The Lexicon’s document uses Hexa, L.Objects uses Hexa,
Experienced Max user advice needed :-)
Thanks a lot

> But I have to say that the guys who wrote the PCM’s sysex
I had a look at the sysex for the Lexicon LXP-1 and LXP-5 many years
> What is the best format to handle complex sysex
I don’t understand the question. Integers are integers; the values are

Hex is the way to deal with single bits. And it is shorter than decimal and synth-people are used to it. I personally avoid Hex whenever I can (I am not used to it). If you talk to electronic devices via messages it is really only a question of number formatting.
Nice to meet you here!

Thanks for intake, I guess I will go the decimal way.

Don’t forget the max “number” object supports displaying hexadecimal.
Sprintf should be able to convert integers to hex: [sprintf %x]
Good luck with your interface building and do share some patches.

What looks closer in to Max is the Environment in Logic since day one.

The project is going well, I can request and compute all the datas I need from my PCM.
Now I have to make up my mind about the way to display datas on the computer.There are two options:
b) using the datas from the GUI then scale them for every type of parameter to fit with the context
a) is very easy but leads to a quite slow display because of sysex transfert in realtime
b) will provide a light speed GUI response but I have to transfrom the values for every single parameters and the PCM has a lot !
Maybe I should try to optimize the sysex transfert speed first then decide to gon or use option b.
About the PCM 70,
So I would says that I will have a lookt at the 70 after the others.
