Hi everone, I’m creating a preset for the Korg 01RW. It is very similar to the Korg 03R/W which I already made. But there are 3 types of mass changes to perform. See below in the Topic. I can change this of course in the json of the preset, and upload this into the E1, but then I can no longer use the editor for maintaining that preset. **=\> Is there a way I can perform the necessary mass changes, outside the editor and then load them back again into the editor ?** The necessary changes are: 1 There is a bit sequence ```auto "42", { "type": "function", "name": "getChannelByte" }, "30", "41", ``` I need to replace with ```auto "42", { "type": "function", "name": "getChannelByte" }, "2B", "41", "00", ``` in hundreds of places. 1. I also need to reshuffle the multisound list, and provide other names for each sound in the list ```auto "value": 86, "label": "hardflute 2", "index": 86 }, { "value": 87, "label": "pan flute", "index": 87 }, { "value": 88, "label": "pan flute lp", "index": 88 }, { "value": 89, "label": "shakuhashi", "index": 89 }, { "value": 90, "label": "bottle", "index": 90 }, { "value": 91, "label": "bassoon", "index": 91 }, { "value": 92, "label": "oboe", "index": 92 }, ``` 1. Last but not least, I need to offset certain parsing bytes with 4 to 8 bytes in the json like in the code below where 149 must become 153, 150 =\> 154 etc… ```auto "parameterBitPosition": 2 }, { "parameterNumber": 1208, "type": "virtual", "byte": 149, "bitWidth": 1, "byteBitPosition": 1, "parameterBitPosition": 3 }, { "parameterNumber": 1208, "type": "virtual", "byte": 149, "bitWidth": 1, "byteBitPosition": 6, "parameterBitPosition": 4 }, { "parameterNumber": 1208, "type": "virtual", "byte": 149, "bitWidth": 1, "byteBitPosition": 2, "parameterBitPosition": 5 }, { "parameterNumber": 1208, "type": "virtual", "byte": 144, "bitWidth": 1, "byteBitPosition": 4, "parameterBitPosition": 6 }, { "parameterNumber": 1208, "type": "virtual", "byte": 149, "bitWidth": 1, "byteBitPosition": 3, "parameterBitPosition": 7 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 4, "parameterBitPosition": 0 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 0, "parameterBitPosition": 1 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 5, "parameterBitPosition": 2 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 1, "parameterBitPosition": 3 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 6, "parameterBitPosition": 4 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 2, "parameterBitPosition": 5 }, { "parameterNumber": 1237, "type": "virtual", "byte": 144, "bitWidth": 1, "byteBitPosition": 5, "parameterBitPosition": 6 }, { "parameterNumber": 1237, "type": "virtual", "byte": 150, "bitWidth": 1, "byteBitPosition": 3, "parameterBitPosition": 7 }, { "parameterNumber": 1229, "type": "virtual", "byte": 151, "bitWidth": 1, "byteBitPosition": 4, "parameterBitPosition": 0 }, { "parameterNumber": 1229, "type": "virtual", "byte": 151, "bitWidth": 1, "byteBitPosition": 0, "parameterBitPosition": 1 ``` ---

You can import the edits json back into the editor, no? At least that’s what I’ve done in the past. ---

That would be nice, how do you do that? ---

The import project button button on the main page of the web editor 😉 ---

it works, just don’t forget to upload the lua again afterwards in a separate step. ---

Ah yes, forgot to mention that.
