FR: Improvements to LEARN (SysEx)

Question

I was adding a lot of new controls to a layout that send SysEx with embedded V - variable....

It would be nice if there was a way to set the checksum default value so I don't have to always set Roland 3 Byte. So setting the checksum then clicking a button  called "SET DEFAULT" would mean the next control added would have the same DEFAULT checksum style.

The midi learn would then automatically know where the checksum was and after clicking LEARN and listening to a stream of messages could ...

1. See which bytes changed and assume they are the value (1 byte or 2 byte) and set that value automatically

2. Figure out what the min - max of the value was - as user would do a full deflection of the control from its min to max position then set the midi min max accordingly

3. If value was 2 byte it could also determine MSB LSB order based on which of two bytes changed most frequently in the message stream.

Comments

Thanks for this, Chris, so: would it be helpful to have #0 without the others, at least initially?

It would be kind of useful to have the default value, but that can be kind of worked around by doing a "make similar" which carries forward the checksum value. So that would be kinda useful.

What would be super cool would just have LEARN train as many aspects as possible, Sysex string, midi min max, display min max (default same as midi min max), number of bytes in value.

I think this is one of those all or nothing things, as it would be so cool when fully implemented. So well worth waiting for as a full feature.

I did a layout with 36 sysex control knobs on, and believe me, it took hours to tweak and perfect, when I recking this feature would have let me do it in about ten minutes...dump all the knobs on the page, then rename the labels, then just keep clicking LEARN. Also, not having to click APPLY after a LEARN would make it very slick to just move from one control to the next LEARN'ing each control...slick and efficient.

I *think* that if the box is sticky (top right corner red LED turned green) you don't have to hit apply. No?

When I do use the learn function with Sysex and I have the Roland checksum on, I always need to delete the last byte b/c that is the chceksum...... kind annoying if u have layout with 100+ controls. The same with using of  V. If I use V and I hit the learn button, I get response that it is 3 bytes long which puts  two extra bytes after the V that needs to be deleted
