Midi faders and encoders

Hello! I’m looking to add something like an akai apc40 to a pc rig for control over midi. To test some of this, I fired up my novation impulse 49 which has some faders and some infinite spin knobs I thought would be good for controlling the encoders. Well, I never got the faders to work at all and the knobs I could make talk to the hog encoder wheels, but only a small range. I did have to change the mode from7 bit absolute to 7 but relative but it was only changing part of the intensity encoders value range. 0 on the midi knob wasn’t 0% on hog and 127 on the knob wasn’t 100% on hog. What am I missing? Do I have to have something bomes midi translator or is there something I’m doing wrong? Thanks in advance!

    We've done extensive testing with the Akai ap40 mk2 with good results. Faders, knobs, buttons all work.

    Awesome! So I’m not missing anything? Just need the apc 40 and my laptop for what I described to work?

    That's correct just the APC 40 and Hog 4 PC on your laptop.

    Checkout manual section 21.2.1 MIDI Map Editor for more info

    Remember to put your encoders as MIDI Type: Controller in "relative" Mode
    Buttons like 1, 2, 3, full as MIDI Type: Note
    and faders as MIDI Type: Controller in "absolute" Mode

    Ok so when I bought the apc40 yesterday I didn’t have my pc with me. I was able to get everything working fine on my mac running hog on windows via bootcamp. Fired up my pc rig this afternoon and most everything is working except I can’t get the apc faders to control the hog faders. I can make the apc faders control an encoder wheel in hog so I know they are talking. Seems like it’s something weird with the faders on hog on this machine. Is there another setting within hog that I should check that may allow/disallow remote access to those? I also tried every mode in the midi map and none of them worked (relative, absolute, 7 but, 14 bit, etc)

    APC40 faders are 7 bit absolute. Make sure there is a playback item assigned to the master for the hog fader. For example, if trying to control fader 2, don't expect to see the Hog virtual fader widget 2 move on the virtual front panel unless there is a playback item on master 2.

    That was the issue. I didn’t have a playback assigned to that master. Thanks! All seems to be working now!

    are faders always 7 bit Absolute?
  • datadriverdatadriver Registered User, HES Staff
    @alsandy No, it depends on the MIDI hardware being used.

    Hi All, does the APC40 Mk 1 also work or is it just the Mk2 that has been tested? Cheers
