    Hi @TasTax - I don't think Octachron is feeding back AUv3 parameter values to the host. That limits its effectiveness in hosts that can display parameter values, or record parameter changes from interface actions. Tested with the update that dropped today in Loopy Pro, Drambo, and AUM.

  • What an incredible update!!!!

    @egobeats and @wim , thank you!

    we will check this. Does anybody else have these issues?

    100% - Including preset export and import! Been waiting for that one - now I can share my presets out for other apps like BeatHawk and OneShot.

  • I haven't used Octochron in quite a while because it previously wasn't possible to change patterns using MIDI notes when used as AuV3 (only standalone). Has this been implemented now?

    You can midi-learn the AUv3 parameters for activating patterns. I don't know if there's a way to do it with direct midi to octachron, but the Uv3 parameter route works. (With the exception that no feedback is provided to the host.)

    OK thanks. TBH I find it a baffling exclusion, and means it is unusable for my purposes - live drum sequencing. For that I need the precision of MIDI notes, not MIDI CC values. It's a common feature of almost every other plugin sequencer I've used, and is available in the standalone version. Perhaps I just don't understand the philosophy behind the design.

    How are other users switching between patterns i.e. how are you 'sequencing the sequencer'?

    yes, this is a feature of our latest update 🙂

    Hi. In AUM you can MIDI learn notes to switch between Octachron patterns (turn Cycle OFF). You should be able to do it with buttons sending on/off CCs as well. It's not about CC values, just off/on.

  • @stim said:

    Notes will work with the AUv3 parameter.

  • @stim, I can confirm that you can trigger patterns with midi notes direct to the plugin.

  • Hey @wim,
    thank you very much for reporting the issue "I don't think Octachron is feeding back AUv3 parameter values to the host". I did not realize I'm missing this part. It's working for active and mute parameters. But I was not properly updating it for the pattern change parameters. I'm uploading a new beta right now will release it as well soon. :)
    Cheers

    Hot diggity!

  • Nice! Thanks @TasTax. That’ll make using Octachron even nicer in Loopy Pro and Drambo, among other hosts. 👍

  • When I use Octachron in Aum to control Oneshot I use the oneshot preset.

    But it doesnt work.

    Only the kickbass is makes a sound

    The rest of the sounds like sd make no sound while I do have made an sd in oneshot.

    But octachron doesnt trigger it.

    Anyone got an idea why?

    Look in Onshot to see which note is triggering along the bottom of the screen as Octachron plays the snare. Make sure the sd that you set up is mapped to that note. If not, change it either in Octachron or in Oneshot.

    Yes thanks,
    I was hoping it would do that automaticly since it is a specific preset in Octachron

    Octachron doesn't have any way of knowing the actual assignments in OneShot, since those are customizable. The Octachron preset is just a guess at a typical setup. You may have more luck using the General Midi 16 or General Midi 8 Octachron presets. Many of the OneShot kits are set up for the General Midi drum map.

    Heyhey @Meek3 and everybody!

    Thx for reaching out. And sorry that our preset does not work accurate with the current version of OneShot.

    Could someone maybe share his working preset here with our share function? Then we will integrate it in our next update.

    Thx a lot and best greetings from Munich 🙂

  • Hi @TasTax - the compatibility isn't version dependent with OneShot. Kits don't have a fixed mapping and they can be altered as well. I'm not sure how you could have a general OneShot preset. Most OneShot factory preset kits are General Midi mapped, I think.

    A shame that not all drumcomputer apps are general midi. Would be easier I think.

    There are a number of problems with that. There are 46 notes defined in the GM Drum map. Most drum apps don't have nearly that many sounds. For example, there are six possible toms. What do you map to when an app only has three? What do you do about apps such as Ruismaker, that can define any sound on any pad? How about Ruismaker FM that has only six when Ruismaker has eight?

    There's no simple answer to drum mapping that works in every case. The best you can hope for is apps like Oneshot and Octachron that make it possible to customize maps.

  • OCTACHRON has stopped working with Audio Evolution Mobile The sequencer won’t run. But other MIDI sequencer AUVs work as normal.

    It still works with my other DAWs (NanoStudio 2, Drambo, BAM). Neither OCTACHRON or AEMS have been updated since it was last working. I’ve not updated my iOS (16.7.14) either. I’ve restarted my iPad.

    Anyone have any clues? I’m going to post on the AEMS thread as well.

  • Reinstalled OCTACHRON, which didn't fix the problem. Reinstalled AEMS, which did. Thanks, anickt!

    Ok, I see, thank you! 😊

  • I’ve been trying to lay out drum tracks using OCTACHRON in AEMS, exporting sections as midi clips for visual arrangement. But midi clips exported from OCTACHRON always play back at the wrong tempo, like 4x faster, as if there’s a clock divider mismatch between both apps. Any clues as to what I may be missing?

  • Is anyone exporting midi clips from OCTACHRON and laying them out in a DAW timeline to build drum parts? Interested to know about others’ results and workflows using OCTACHRON.
