Hi there, For some time now, I have my preset web editor not showing the response properly anymore. I made multiple tests to find a solution (creating some new presets, trying on some other presets from other people that I know that are working, etc.). I can still do the mapping via the JSON, but it’s way more tedious… Here’s the behaviour for the latest test I made with a new preset: **Request/Response settings:** ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/2X/b/b3a174fe1ffd8775f86b1951c265d714a75f26a4.png) **The corresponding JSON:** ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/2X/b/b67cbc6e8998610523f74c4969cf19c01c11421a.png) **Captured message:** ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/2X/4/4db11d384758c882187b3935a7a1645634dd24b3.png) **Sysex request and response:** ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/2X/a/ad183675d8d77710edb488ec9d4c627a68f5d5a0.png) I have no idea why there are only two bytes showing up after the header with the end of the sysex (F7H) appearing already in byte 2 when the captured response is actually 32 bytes long. Note that the first sysex start byte (F0h) also appears twice??!.. Or am I doing something wrong ? Many thanks for your help ! 🙂 ---

You are not supposed to put the start and end bytes yourself in the request nor in the response. Take away bytes F0h and F7h and try again. ---

Hi NewIgnis, First a big thank you for your insights and all the help you’re offering to newbies like me. Among other precious sources of information I read your [Adding patch parsing to a preset. Step by step](https://forum.electra.one/t/adding-patch-parsing-to-a-preset-step-by-step/2117) thread which was very valuable for getting started. However I guess I read it a bit too fast… 😃 I fixed it and it works obviously, and I don’t understand how I got it to work in the first place. But I’m still having a problem with the preset web editor response display. On another preset I’m currently working on (Cheetah MS6), I get the response displayed only with zeros, which doesn’t correspond to the sysex response I’m getting back. For example: ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/2X/9/93904eef282b893c26672b96ccc7680dac1f20ac.png) Whereas the sysex request/response are the following: ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/2X/a/af9841b5f0033a093e14f302177927ef7aec8429.png) It always stays all filled with zeros even when i change patches on my MS6 and trig another request, but the changes in the bits between the different requests/responses are still being marked in green. Very strange… What have I done wrong this time ? 😃 Again, many thanks for the help ! ---

Very good of you to provide screenshots, that helps to help 🙂 By the looks of it, the response header you ask the electra one to look out for is different from the one the MS6 is sending you. E1 expects 36,02,00,08, **01** Cheetah is sending 36,02,00,08, **00** ---

I assume you have the Maad Firmware on the MS6? Care to share its sysEx manual? If it is the buffer memory of a tone you want to read , I suggest you use the response header 36 02 00 08 00 01 ---

NewIgnis, you’re amazing ! But now I feel really bad for not having detected the error by myself… Lesson learned I hope: always quadruple check my work before searching for bugs… I don’t really like to publish non finalised work, but as I might ask for some help in the future, because of the weird sysex responses I get, here’s the preset: [https://app.electra.one/preset/rZlkwcS0p2wJ1RuejYJm](https://app.electra.one/preset/rZlkwcS0p2wJ1RuejYJm) Thank you again and I which you a pleasant week !
