I have a question regarding certain sysex messages .
I have notices that for the roland integra , the last two values are defining the parameter value change ( anaysed from unpack sysex ).
For example , here's the filter envelope depth for partial , the value (rectangle red )increases , while the value (rectangle green ) decreases

I then copy paste the array into a template module and make the next to last value a variable , and magically it works perfectly when sending out sysex , while the last value stays at 1( I could set the last digit to any other value , it keeps working )

So I wonder why is that last value changing (when receiving sysex ) , has this to with msb,lsb

It could be, but without seeing the SYSEX specs for the Integra, I'd be guessing, and a quick Google search turned up nothing. If you have the docs to hand, I could take a look.

If it isn't an msb/lsb pair, it may be that the final value is a checksum. Each value is unique in your output so I can't confirm this, but if you record more input and always get the same pairs (2, 116), (5, 113), etc, I'd wager that's what it'll be.

hmm this is weird
When I change the filter type (or anything other) , I get a totally different sysex message in renoise
All done on cannel 1
Of course renoise shows hex values , but it also shows stuf that architect doesn't
Renoise

architect

and renoise

I am pleasantly surprised with the sysex handling , it works wonderfully for the roland integra
I know I am sort off re-inventing the wheel since there already is a full blown editor that works as a vst3 ( but crashes architect ..for the moment )
As long as the hardware device is able to send sysex (which architect captures ) it's just a matter of copy paste the data in a template and replace the parameter with a variable , and of course some deciphering

, lot's of copy pasting since 'set midi channel 'module will not magically route the sysex data to a new midi channel , midi channels have to be inserted in the sysex data string
Next one the list is the yamaha tg77
