Recent firmware update?

It's been a couple months since I checked for one with my amp but I cannot find anything online about a recent one. - 14 Jun 2017 at 05:54 PM

Hello Mario,

There is no procedure to roll back the recent firmware. Why would you need to? are you having any issues with the new firmware?

We haven't received any details of anything specific. If you can give us any information on potential issues with the firmware we can investigate? - 13 Jun 2017 at 09:38 AM

do you actually read your own forum????
- 13 Jun 2017 at 09:42 AM

Yes, we keep a regular check on the forum. The last issue regarding firmware reported was a problem with the Chrome WebMidi, this was solved by updating the advanced settings in Chrome, which we gave instructions.
If there is anything else Firmware related that you feel we have not addressed then please do let us know. - 13 Jun 2017 at 09:51 AM

as i have stated previously my code 25 is straight out of the box as sold. no updates. works fine with the new gateway app though with my hand me down Samsung galaxy 5 and I have no issues with connectivity or the amp at all. so I'm a very happy code owner. unfortunately though it seems reading through the many threads, I may be in the minority, or, perhaps a silent majority :-)

I enjoyed my new CODE 50, it sounded awesome, every preset was good. Then... i decided to give it a firmware update end something happen that made the AMP sound horrible. After the update all i have been doing is try to figure out how to make it sound good, no guitar practice time.

Someting in the update made a change to that amp where it makes it sound horrible

I have requested details from our tech team of what changes were included in the last update and if any of these could have had an effect on the sound quality of the CODE. When you say it sounds horrible, can you be a little more specific? what sound is making it horrible? are you able to send any kind of soundclip to our helpdesk team?

sorta like trashy sounds, it is not clear when playing more than half of the presets. as if the guitar was so badly out of tune which is not. I found many other users having the same issues by doing searches in this forum and the internet only no one has an answer about how to fix. - 13 Jun 2017 at 11:44 AM

any updates? - 13 Jun 2017 at 06:45 PM

Not as yet, i am waiting on the tech team to get back to me. I will update you as soon as i can. Thank you for your patience. - 14 Jun 2017 at 08:49 AM

I have experienced a recent issue with that as well. The DSL OD and British pre-amps developed a very digital tone to them which is very noticeable when playing an E or F# power chord. It sounded fine when I first got it but developed the issue after the last firmware update. - 19 Jun 2017 at 07:55 PM

The following changes were made in the last updated firmware -

2-way footswitch support
When a 2-Way momentary is connected to CODE, current preset can be incremented or decremented.

USB audio
In some circumstances USB audio playback and record would lose synchronisation causing cyclic patterns of distortion.

Storing Presets
In some circumstances CODE would freeze when storing a preset.

Bluetooth pairing
CODE remains permanently muted while in paring mode, BT discovery time increased.

Gateway Presets
In certain cases preset data from Gateway library was not received correctly by CODE.

4-way foot controller
Increasing delay time over 2000ms causes second 7-segment display to flash.

These changes should in no way affect the sound in the presets. We will carry out testing on units pre firmware and after firmware update to see if there are any issues regarding the sound quality. Any change in sound may be related to an unconnected event that happened around the time of the update. We will investigate this further. - 20 Jun 2017 at 08:06 AM

Let us know the outcome because there is very little chance more than one person, including myself, experience the same issue.
Something definitely chances in the sound of more than one preset.
can they just let us have the old firmware and we can load, it should work if we have it. - 21 Jun 2017 at 02:09 AM

any updates
can the firmware update people post the original firmware so that we can roll back?
can the firmware update people post a new update?
I need to know before i have to return my CODE 50 as it now, after the firmware update, seems defective. - 24 Jun 2017 at 05:50 PM

any updates?

We have tested CODES pre and after firmware and we are not receiving any change in the sound quality that you have reported. As we are unable to replicate the problem you are experiencing we can only assume that your CODE may be defective. We would suggest returning your CODE to where you purchased it from and request it be looked at by an engineer. - 29 Aug 2017 at 08:45 AM

can it be replaced by Marshall warranty? - 29 Aug 2017 at 12:04 PM

btw, i did read the questions from others and many others seem to have the same issues after firmware update.
