I have the SE-02 editor from Studio Electronics, so I thought it might be worthwhile monitoring the traffic going on between the two of them. The editor only finds the SE-02 via USB, **any one has an idea how to intercept USB MIDI data from editor into SE-02** (MIDI thru won’t work, I tried that, but the editor won’t connect with the SE-02 if midi thru or MIDI echo is on)? I’m pretty sure it is MIDI ! The other way round is easier, by monitoring what came out of the DIN MIDI OUT of the SE-02. Here’s what I found: if the editor requests a patch from the SE-2 , the SE-2 responds in 4 chunks: 3 times 78 Bytes, and one time 62. ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/1X/8b51aeac1cd5834c997c77b40b36e003a54bb007.png) The header starts as follows `F0` `41` = Roland `10` = Device ID (if the SE-02 follows Roland standards) `00 00 00 44` will be the Model ID SE-02 (Roland typically adds one or more 00H’s in front of the Model ID to ‘differentiate various things’ (found in D-05 MIDI manual) `12` is usually a Roland command ID (DT1) for transfer while `11`= RQ1 is the counterpartner for Request. So my guess is where are indeed looking at a data transfer where shortly after `12` is the body , consisting of an address then data and it ends with a checksum. When the SE02 editor is finding the SE-02 for the first time, this is what the SE-02 responds : ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/1X/ec4a275d15b888743bcc0de6dae6e21226d46400.png) Last check: retrieving the first patch of the first bank, for which I know it is called INBOUND . I believe the names to be 16 digits long. The name is in the second to last row: `49 6E 62 6F 75 6E 64` and a bunch of zero’s stand for “Inbound” ![image](https://europe1.discourse-cdn.com/flex017/uploads/electraone/original/1X/6d07ef49e08c300af8427abf22710716cc7af006.png) Hope this has some value for someone somewhere 🙂 --- _[View the full topic](https://forum.electra.one/t/preset-roland-se-02-v2/1180)._
