Hello ! I’ve been refining a preset on the E1 for use with Ableton Live. It’s for a specific Ableton file I use in every live gig. It’s been updated over the years and I’ve combined it with a variety of different midi controllers. It was great fun to start creating the preset even before the E1 arrived in the mail ! I’ve had the E1 for a month, and it’s been great. But yesterday I did a minor tweak to the preset and got a glitch. I duplicated a fader (pan style, -63 to 63, unsigned 7bit) and the new fader never sent any midi data. I tested the midi output with midi monitor on a mac. I went into a dig to understand the bug and this is what conclusions I got to : - Only happens with pan style faders unsigned (I suppose they have a name !) - Normal faders work just fine - Sign bit and “two complement” work perfectly too I also created a fader from scratch (not only a copy). Tried various CC values. What I don’t understand is that I have many of these types of faders working fine in my preset. Any ideas, something I should test or check ? E1 is running firmware 1.5 Thanks, Jesse ---

I have had a similar problem, and was told it may be a defect in the web editor. I am sure Martin is working on it and will chime in regarding a solution. ---

Thanks Marzzz ! I did suspect it might be a problem with the web editor. I’ll just have to stick with regular faders until Martin offers a fix. No big deal 😃 ---

I can confirm I am seeing the same error with the unsigned 7 bit faders. ---

I downloaded the .epr files for a fader that has each of the sign modes. The only difference i saw was that the twos complement and signed bit had the following key/value pairs: “signMode”: “signBit” “signMode”: “twosComplement” The unsigned fader did not include a corresponding signMode key/value pair. The missing key/value pair may not be the issue, as one could just check for the absence of it to make a determination in the codebase. ---

Nice idea, I also downloaded the code and had a look. I compared the script for my “old” working faders and a newly created one and found a difference in the formatting : A working fader looks like this : “values”:[{“message”:{“type”:“cc7”,“deviceId”:9,“parameterNumber”:0,“min”:0,“max”:127},“min”:-63,“max”:63,“defaultValue”:0,“id”:“value”}]} And a new non working one like this “values”:[{“message”:{“type”:“cc7”,“deviceId”:1,“parameterNumber”:2,“bitWidth”:7},“min”:-63,“max”:63,“defaultValue”:0,“id”:“value”}]} Not really a solution, but it might be part of the problem 😁 ---

There is a link somewhere on the forum that allows you to manually push up .epr files to the Electra.one. Its possible that if you alter the non-working faders manually with the min max values that you have verified are working, it might be a nice work around. I am going to see if I can try that(first by finding the manual pushing software), as I recently created some new presets and my electra now has a whole bunch of parameters that dont work anymore. ---

So here is a way to get around it, based on Jesse’s and my research: Create your preset on the electra editor. Download the preset as a .epr file. Open the .epr file in a code editor, such as [Atom.io](http://Atom.io) (on Windows notepad will probably work) In that .epr file, each fader that uses display values that are positive & negative and of the unsigned type show up thus: ```auto { "id": 3, "type": "fader", "name": "TRANSPOSE", "color": "FFFFFF", "bounds": [ 340, 40, 146, 56 ], "pageId": 1, "controlSetId": 1, "inputs": [ { "potId": 3, "valueId": "value" } ], "values": [ { "message": { "type": "cc7", "deviceId": 14, "parameterNumber": 6, "bitWidth": 7 }, "min": -48, "max": 48, "defaultValue": 0, "id": "value" } ] } ``` In the message section of each fader, you will need to add the following: ```auto "min":0,"max":127, ``` So that it looks like this [you will see it right below the parameterNumber]: ```auto { "id": 3, "type": "fader", "name": "TRANSPOSE", "color": "FFFFFF", "bounds": [ 340, 40, 146, 56 ], "pageId": 1, "controlSetId": 1, "inputs": [ { "potId": 3, "valueId": "value" } ], "values": [ { "message": { "type": "cc7", "deviceId": 14, "parameterNumber": 6, "min":0,"max":127, "bitWidth": 7 }, "min": -48, "max": 48, "defaultValue": 0, "id": "value" } ] } ``` Once you are done adding those Min/Max values to your .epr file, copy the text of the .epr file [using CTRL-C or CMD-C] and paste them into the following sandbox: [Electra One App Sandbox](https://app.electra.one/sandbox/) Make sure your Electra One is connected to your PC and upload. Voila. I tested it, and it worked on mine. This is just a work around for now. I am unsure when we are going to get a fix for this, but it seems like it should be a quick fix on the editor. @martin Thoughts on when we might get a fix for this? ---

I didn’t know about the manual upload option. Thanks for looking into it and I’m glad my little research proved useful in the end. I’ll probably make a manual edit for the time being. ---

Umm, I think I’ll just wait for Martin to update it…! ---

hi, I am preparing a release that includes the fix of this issue. The firmware is ready. I need to coordinate release of new web editor and electra console app. sorry for being silent, I had troubles with typing on the keyboard recently. It is better now. Yes, the problem is caused by the fact that the unsigned ranges require `min` and `max` parameters. The fixed version of the editor provides input fields for these when `unsigned` type is chosen. The other sign types still require bitWidth only. I hope it is sufficient and makes sense. Regarding the release, we are aiming at this afternoon (Europe). The release will be quite big - firmware version 2 goes out of beta - I will be available for any assistance and issue fixing during the weekend. And big thanks to all who worked on finding the solution of the issue! ---

The new firmware is out. Will make an annoucement in a separate thread.
