    1440 firmware update 0.57 is available now through the 1440 Loop Manager app, which can be downloaded from this link: 1440 Loop Manager app.

    Version 0.57 includes bug fixes for improved MIDI Clock sync stability, better MIDI Continue message support, and saves loop fade settings for each loop, through loop fade settings and power cycles. The update also adds MIDI control over nearly all 1440 functions, controls, and parameters through MIDI Program Change (PC) and Control Change (CC) messages and adds a MIDI mode menu where you can set the receive MIDI channel for PC and CC messages.

    Electro-Harmonix 1440 Version 0.57 Release Notes
    December 16, 2021

    1. Bug fix: MIDI SYNC: Improved stability when syncing to external MIDI clock. Tempo and pitch wavering are substantially reduced for most MIDI clock sources. When changing to a new MIDI tempo, the 1440 will take more time to stabilize at the new tempo. This is by design.

    2. Bug fix: MIDI CONTINUE SUPPORT: MIDI Continue messages are now treated the same as MIDI Start messages. Some DAWs will only send a Continue message instead of a Start message when pressing play in the middle of a track. This change introduces compatibility for these DAWs and any other source of MIDI messages that might exhibit such behavior.

    3. Bug fix: FADE TIME SAVED: The 1440 now remembers each loop bank’s fade setting through loop erases and power cycles and until you change the fade setting again or reset the 1440. A loop bank’s fade setting is saved to memory upon stopping a loop. To save a Fade setting, you must either playback or record a loop for the given loop bank, then stop the loop. Once you stop the loop, the setting is saved. Here are the steps to set the Fade setting for any given loop:

    a. Press the MODE knob so that the current menu label blinks.

    b. Turn the MODE knob so that FADE is displayed and blinking.

    c. Press the MODE knob.

    d. Set the FD setting. For example, FD.03.

    e. If the loop bank already contains a loop, press the LOOP footswitch to play the loop. If no loop is in memory, press
    the LOOP footswitch to record a loop.

    f. Stop loop playback by either pressing the STOP/FX footswitch or double-tapping the LOOP footswitch.

    g. The fade setting is now saved for the loop bank. You may exit the FADE menu if you wish.

    4. Added Features: MIDI FUNCTIONAL CONTROL: The 1440 now supports MIDI Program Change (PC) and Control Change (CC) messages to remotely control most functions and parameters on the 1440. Additionally, a new MODE menu has been added called MIDI, which allows the user to set the 1440’s receive MIDI channel from 1-16, Off (ignores MIDI PC and CC messages) or Omni (receive all MIDI channels). See item 5 below for more on MIDI channel. The following is a list of supported PC and CC messages and the functions they control on the 1440:

    CC 117 / SWFX setting / 0 to 4 (0 = Stop, 1 = Oct, 2 = Rev, etc.)

    5. Added Feature: MIDI RECEIVE CHANNEL: A new mode menu called MIDI has been added to the MODE knob. The MIDI menu allows you to set the MIDI receive channel for PC and CC messages. The channel range is 1-16, Off – where the 1440 ignores MIDI PC and CC messages but still can receive MIDI Clock messages — and Omni – where the 1440 accepts MIDI messages on all channels. By default, MIDI receive is set to channel 1. How to change the MIDI channel:

    a. Press and release the MODE knob so that a menu heading is blinking.

    b. Rotate the MODE knob until MIDI is displayed, and blinking, on the display.

    c. Press and release MODE. The display should now show MD.xx.

    d. Rotate MODE to clockwise to progress upward through the MIDI channels. Rotate MODE counterclockwise to progress
    downward through the MIDI channels. OFF is represented as MD.OF and is located below channel 1. OMNI is represented as
    MD.OM and is located above channel 16.

    e. Once the desired MIDI channel setting is shown on the display, press MODE to exit the MIDI channel menu. The MIDI channel is
    now saved and will be remembered through power cycles and until you change it again or reset the 1440.


    Thank you for the update! May I have your attention here?

    1440 Looper Octave/Reverse Sad Limitations


    Thank you for the update!

    Note that the PC messages starts from 0 not 1!
    For example:
    Right PC Number / Function / Wrong OLD PC (as stated by EHX)
    PC 0 / Select Loop 1 / PC1
    PC 1 / Select Loop 2 / PC2
    PC 3 / Select Loop 3 / PC3

    So if you follow the EHX chart, just remove 1 from the PC number.
    The Midi CCs do match.


    First experiments with EHX1440 controlled by a MorningStar MC3 were quite successful!

    What I’ve successfully programmed so far:
    – switch A: Reverse on/off
    – switch B: on release Octave on/off, long press release sends midi CC for Overdub knob to set it full/127 or lower/88 for loop decay on/off when in Overdub.
    – switch C: on release Undo/Redo, long press release Loop Erase (as 1440 will erase the loop only after having received 3 times erase PC messages in a row… why EHX? it took me a while to figure out how to make this work properly…. on MorningStar the best solution was to use the long press scroll option to send a ricochet of track erase PCs combined with a llong press to send out Stop track PC, but it’s still not working every time.)
    – switch E: midi CC for Tempo knob for full (120BPM) or half speed (60BPM), a long press release sets the CC to 127 to have 1 octave higher (240BPM).
    – switch F: momentary replace by sending PC for Loop Fw and CC for Overdub knob (works very well with long replaces, but short replaces are a bit tricky due to the way the 1440 works, since a fast dual press of the loop fw triggers a loop stop command)

    What I still have to figure is why the midi CCs are not reacting to the MC3’s waveform generators (here the idea would be to control the Tempo knob to create wow/flutter tape style modulation effects).


    Here’s a demo & review of the midi mapping and a tiny guide how I control 1440 with an external midi controller:

    Gila_Crisis, thanks for the great video review. It was great to see the new MIDI features in action.

    You are correct that the reason we require three consecutive PC erase messages before a loop is actually erased is to act as a fail-safe so users don’t accidentally erase their loops while scrolling through PC messages. We understand this is annoying to deal with. Maybe something we could consider in a future firmware update is to add a second loop erase PC message which will erase the loop immediately with just one received message. We would probably make it the highest or second highest PC number: 126/127 or 127/128) so that it will be difficult to accidentally send the PC message while scrolling through all the PC numbers.

    Are the MIDI CCs now reacting to the MC3’s waveform generator? It seems like in the video that is now working?

    Thanks again!


    Hey Flick, thank you so much for the great update! The midi mapping is just amazing.
    Yes, 1440 is reacting very well to MC3′ waveform generators (and you can do wonderful crazy stuff with these, as I told in the video, there I was just scratching the surface what you can possibly do)!

    The Wave-generators not working was my mistake… I forgot that when you edit the MC3 by connecting it to Editor App, the generators will start work only after MC3 is disconnected from the Editor.


    Awesome! Glad the wave generator is working with the 1440’s CC mapping.


    Also, it would be very handy to have PC messages for these specific functions: REC, DUB and Play.
    Like PC30 for the Stop.


    I found a bug on 0.57:
    – The Midi PC Nr. 31 (32 in the list above) RV.OC function doesn’t work properly: when I send this one to 1440, it’ll engage both Reverse and Octave as expected, but it also changes the function of the Stop FX switch to Reverse and Octave, no matter how it was set before!

    Otherwise all the the other PCs and CCs are working fine.

    Thanks for finding this bug. We’ll probably fix this bug and add the requested PC messages (if possible) in February or March.


    Great, looking forward to the upcoming update!


    I have been trying to set up my 1440 with my DMC-3XL by Disaster Area Designs. Program changes are working nicely so I can scroll through the loops. The MIDI clock also seems to be working. However, i have not figured out how to program the CC changes. I have tried adjusting the value as Gila suggested, but it doesn’t seem to respond. Any thoughts?

    All in all loving the pedal even before these extra features. Thanks EHX for your great work!


    Can you explain what you would like to control with Midi CC?
    Stupid question: does your DMC3XL send out the Midi CC in the same midi channel as 1440?

    Here few reference points for Overdub and Tempo:
    CC 26 OVERDUB knob: 0 = knob fully CCW/MIN, 127 = knob fully CW/MAX
    CC 27 TEMPO knob: 0 = Knob at zero (60BPM), 63 = middle position (120BPM), and 127 = max (240BPM)

    Anyhow, Midi CC 3: it works but only on values which correspond to buttons/switches as in the PC section (like a value of 21 will trigger the Loops FSW), but since all these functions are already covered by MIDI PCs, I ask myself how much does it make sense to have this CC.


    Gila, thanks for responding!

    Unlike the morningstar,the DMC will scroll through PC messages but when programming a footswitch it only sends a CC message. (*it might make sense to have 21 be a blank message so a PC code for the loop swtitch isn’t accidentally sent.)
    Here are my options:
    1. DEVICE # – set to “3” as is the MIDI # ON the 1440.
    2. CC # – Also set to “3.”
    3. MESSAGE TYPE – set to “ONE” which only sends the high value. Other options include toggle (switches between high and low values), return (sends the high value followed by the low), note (sends a midi note with the high value being the velocity).
    4. LOW VALUE – currently set to “0.”
    5. HIGH VALUE – I have tried “31” for RV.OC and “32” for retrigger but have gotten no response.

    I will take whatever thoughts you have – it would be great to get even more out of my set-up!
