Well, thanks so much @NewIgnis. Indeed I’m not an engineer but just working as a freelance product specialist for Yamaha Music Europe. Believe it or not, I’m the one you had been talking to. 🤣 I just got your first question about SysEx wrong for a reason I don’t remember and thought that I corrected my answer afterwards. But obviously I didn’t make myself clear enough on this. Sorry about that. The SysEx documentation is probably offering everything you need. If you like to download the MONTAGE Data List as an example to take a look, here is the link… > **[montage\_en\_dl\_c0.pdf](https://europe.yamaha.com/files/download/other_assets/5/812525/montage_en_dl_c0.pdf)** > > 4.85 MB But unfortunately my scripting knowledge is about zero and I also never worked with this advanced things like bulk requests and stuff like this. At least I managed to work with SysEx for regular controllers and buttons after going the hard way of try and error because the documentation IMHO leaves “some” room for improvements in this area. My questions about that also stayed unanswered… > [@SysEx | MIDI Learn & Visual Editor](https://forum.electra.one/t/sysex-midi-learn-visual-editor/1570): > > Hi, apologies but again I can’t find something about the topic in the subject in the documentation nor searching this forum. Can MIDI Learn be used for SysEx messages? The manual somewhere says: Always try to twist the knob all the way to the left and then to the right. … I tried using it this way but as a result it just stores the last recognized parameter, not a range. If this visual editor would have been part of the manual I’d maybe able to work with that but I can’t by far get the id… I didn’t even think of concepts for more advanced editing because these would just make sense if I were able to at least get some parameter settings requested that updates the controllers on the E1. Just catching every value from its initial setting is not the ideal workflow. --- _[View the full topic](https://forum.electra.one/t/very-complex-sysex-yamaha-sy-tg77-patch-parsing/1627)._
