Audiobus: Use your music apps together.

What is Audiobus?Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

  • cool. any video demos out there?

  • Does it send midi ?

  • edited June 20

    So it’s like KB-1, plus a harmonizer and an arpeggiator? Wouldn’t this be better built in to its own synth? Maybe someone could give me some examples of where this could be used ideally.

  • Video?

    Yes, its a MIDI plugin.

    Happy to weigh in here. Originally it was supposed to offer similar functionality than KB-1 but designed for use with an external keyboard, since people kept asking for it. Over time it grew to cover a lot of use cases tho.
    Here are a few:

    • Use it with a traditional keyboard either soft or hardware to play/learn scales or single note chords/arpeggios
    • Use it to come up with chord progressions and musical ideas in general
    • Use it as a performance tool e.g. play and manipulate a sequence in real time
    • Use it to generate a basic song structure w chords, bass and melody
    • Use it with multiple instruments to create a backing track then improvise over it (my favorite of all)
    • Use it to explore different scales and harmonies

    I'd also like to see this in use. Thanks.

    working on it.

    I got it and it seems potentially good and useful but I've found some problems:

    Biggest one so far is that if I change any of the quantizer settings, root or scale, while it receives notes, it often stops functioning. No longer hear anything or getting an output. Reloading it is the only way to get it going again. This happens so frequently that it makes it unusable.

    In AUM, looking at the midi routing, there are 62 ! midi inputs going to Harmonicer. That must be a mistake.

    When sending midi notes to Harmonicer it uses the velocity of the notes, which is good. But when I use the ARP, I can't control the velocity output. It always sounds too loud and must be fixed at a high velocity. I think it needs a velocity setting for the arp.

    So it looks promising but that's my bug report.

  • @ka010 Any chance for an iPhone port? I'd love to buy to use it.

    Sorry about this, I've had other reports but are still trying to reproduce it here. Expect a fix soon tho.

    It is... you can safely ignore them, they'll be gone with 1.0.1

    When sending midi notes to Harmonicer it uses the velocity of the notes, which is good. But when I use the ARP, I can't control the velocity output. It always sounds too loud and must be fixed at a high velocity. I think it needs a velocity setting for the arp.

    this too is fixed in 1.0.1

    So it looks promising but that's my bug report.

    Thank you, I appreciate it!

    It'll most likely go universal at some point.

    I thought it was a Harmonica virtual instrument from the thread title. 😂

    Looks handy though ...

    Sounds good. Thank you for the speedy reply mate.

    Great to hear. As a phone only user, MIDI tools get heavy use from me.

    Got 66 inputs in AUM. Looking out for 1.01.

    But I wanted to use 66 note chords! It’s a feature ;)
    Great app @ka010

  • Just bought it, looks intriguing.

  • Anyone know how to move the keyboard under the controls instead of to the right as shown? I’ve seen it in the manual, but can’t find how to move it.

    Didn't see any way to do that. I'm guessing maybe what is shown in the manual is an older version of the app but I'm sure @ka010 could comment.

  • @ka010, Congratulations on the new app, it looks promising.🤩 I can’t wait to watch the demonstrations.

    One question? Is there a dark version of the UI?

    The keyboard is under the controls in the standalone version but in the AU it's on the right...

    Currently its on the bottom for standalone and on the right for AUv3. Starting with 1.0.2 it'll move to the bottom when resizing the AUv3

  • 1.0.1 is live https://apps.apple.com/us/app/harmonicer/id6468485333

    • Fixed an issue where changing scales while receiving MIDI input would stop the plugin from generating MIDI in some cases
    • Fixed an issue where changing scale or root while receiving MIDI input would create hanging notes in some cases
    • Fixed an issue where the arpeggiator would use fixed velocity regardless of the input
    • Fixed an issue where the plugin would expose additional MIDI in ports
    • Fixed an issue where using the arp variation would cause hanging notes in some cases
    • Fixed an issue where +/- octave intervals were incorrect for some scales
  • Definitely curious to see this in action! Looks fun

    Thanks for the update, it certainly has helped a lot. I don’t know whether it’s me but I seem to be having problems when using the keyboard in AUM, I’ve even tried your KB1 and I still have problems. When I play a note on the keyboard it sometimes doesn’t produce any sound or the sound is latched and won’t stop. I’ve kept the setup simple with KB1 going into Harmonicer and Harmonicer into an instrument (I tried various). I would be grateful for any help or advice.

    This should be fixed in 1.0.2 which is out now.

    • AUv3 will now move the keyboard to the bottom when resized
    • Fixed an issue where the progression recorder would not sync properly with the host timeline
    • Fixed an issue where the progression recorder would improperly react to AUM transport controls
    • Fixed several edge cases where hanging notes might have occurred
