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.

Audiobus is the app that makes the rest of your setup better.

    Is there a hack involving sending CCs from another app with a more precise UI ?

    Midi CC (7-bit(Values 0-127)) would not give enough resolution for precise editing.

    Doh .... you're right ... I should have figured that out for myself,

    The MIDI CC values are hard coded in the app. Tom has them up on this website, thankfully, but the app does not have MIDI learn or variable MIDI CC assignment.

    The parameters are all shared in the AUs, so you can use whatever MIDI learn capability your host (AB3, AUM) has to configure them as desired.

    My host of choice, Cubasis, doesn't offer that. 😬

    @burns_audio I understand from preceding posts that my concern (below) has been discussed with you before (slightly different context). If you have any news about changes coming up that might address the problem I'm having I'd love to hear about it.

    BTW, really loving what your app gives me. Knowing what it does, I would have paid for it. Maybe you should think of a way of monetising it for yourself, (e.g. perhaps free for 10 days, followed by limited controls until in-app purchase ?) assuming the mutable licence doesn't prevent you from doing so.

    I'm finding it hard to set exact values e.g. when the harmonics knob controls a frequency ratio, it's quite important to be able to hit 0.5 or 0.33 for harmonies.

    I always find that even if I can get the knob to the value I want, when I lift my finger the knob jumps by enough to mess things up and produce a beating effect.

    Has anyone found a way round that ?

    I tried long press, double-click etc to see if there was another UI to set the value, but no luck so far.

    This sounds similar to something I found a few days ago (and never got around to mentioning) so the details are now a bit hazy. But I did find something going on where two notes (close together) on the keyboard behaved differently WRT the release part of the envelope. Almost like note-off was being ignored for those two notes, or being ignored for all the other notes, all I know was the release effect was markedly different on those two notes.

    EDIT: See post below, I've done some more investigation.

    The effect was observed both on the AB3 on-screen keyboard and via an external keyboard (midi-routed by AB3).

    The Release setting on the Amp Envelope doesn't seem to function when using the String model. I'm also inconsistently getting some weird behavior from it where notes sound wrong, some differently so:

  • Alright ... I've re-created the problem. Within spectrum, on the modal algorithm, I find there's a difference between E2 and F2 and B2 and the other notes within the octave C2-C3

    For both E2, F2 and B2 when the notes are released on the keyboard (either internal AB3 one or external one) then the notes ring on as if nothing had happened. For all the other notes in the octave C2-C3, on lifting my finger from the note, there is an abrupt stop to the sound. For all these notes, the release setting on the ADSR does nothing, which I presume is by design.

    Any thoughts on this @burns_audio ?

    However ... I've just discovered the problem notes keep moving, now it's F#2, G2, G#2 ... and the more I play, the more chance that the problem notes move again.

    Internally, Spectrum allocates 8 instances of Plaits and then assigns them to whatever notes you play. If you play the same note multiple times, it'll re-use the same instance instead of assigning all the notes to the same instance. So it sounds to me like somehow the voice state of some voices is somewhat corrupted and not sounding correctly. The hard part is, how do you reproduce corrupting those voices from a fresh instance of the AU? That's what I haven't been able to nail down.

    Okay ... understood. I did find that if I moved away to another algorithm and came back to modal, that the problem cleared and I could not reproduce it. If I discover a way to do that in the course of playing I will let you know. Thanks.
