The best thing to do right now is to email EHX customer service at poster@ehx.com. They can help you figure out the repair.

If you have the OVERDUB knob set to max and it is still erasing old audio as you overdub, this sounds like a broken OVERDUB potentiometer.

How new is your 1440?

Did it always have this problem or did it begin with a firmware update?

Loop progress mode is definitely on the list for a future 1440 firmware upgrade.

@romzin I understand what you’re looking for now. We’ll look into loop bank play/record transition on the external 3 button footswitch first chance we get. Thanks for the link to your other post.

@Gila_Crisis We’ll update the MIDI mapping in the manual as soon as we can.

Also I see that the MIDI mappings in the manual are not up to date as the manual does not include the three newest messages:

PC 71 (70) – Play function: always initiates the PLAY function unless the loop is empty. As long as audio is found in the currently selected loop bank, and no matter the current mode, sending PC71 will put the 1440 into play mode. PC71 does not start an overdub, record, or stop playback.

PC 72 (71) – Record/Dub function: always initiates the REC or OVERDUB function. 1440 will choose the correct function based on the current state. On an empty loop, PC 72 starts a recording. PC 72 starts an overdub on a playing loop, or immediately starts overdub/play on a stopped loop. During a new recording, PC 72 will close the loop and put the 1440 into overdub.

PC 128 (127) – Direct Loop Erase. Immediately erases the loop of the currently selected loop bank, with no extra confirmation. The loop must be stopped for PC 128 to work. Caution! Once the loop is erased, it is gone forever, this function cannot be undone.

Hi romzin, unfortunately the 1440 will not be able to do seamless transitions between loop banks. The hardware does not support this feature.

And one last thing, version 1.0 of the 1440 works fine on your MacBook?

Hi Gila_Crisis, please try the following on your Mac to establish the USB connection with the 1440. Let us know if it works for you:

1. Choose the Apple menu > System Settings.
2. Click Privacy & Security.
3. Scroll down and click the pop-up menu next to “Allow accessories to connect,” then choose “Always”.

We have version 0.62 firmware available for the 1440 now:

Electro-Harmonix 1440 Version 0.62 Release Notes
October 6, 2023

1. Changed the REVERSE, OCTAVE, and 1-SHOT buttons and the Fade time setting so that their states are stored on a per-loop basis. Each loop slot now stores their own effect button settings and its own Fade time. A loop must be played or recorded and then stopped in a specific loop slot for that slot’s button and Fade settings to be saved. Erasing a loop does NOT reset the button settings.

2. Fixed a bug where importing a loop via USB would sometimes cause its audio to briefly drop out when it started over from the beginning during playback.

Note: Performing this update will reset all three button’s settings to their default/disabled state, regardless of what they are set to globally on the previous firmware version.
