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.

[NS2] Control audio-unit parameter via midiLFOs

LFOs are fun to use as input for quick modulations/automations, onto specific synth parameters or fx.

In Nanostudio 2 I want to use midiLFO to drive the filter-cutoff knob inside an instrument (e.g. Obsidian) or AUv3?

I tried adding midiLFO as MIDI-Fx on a "no instrument" track (or an "external MIDI" track), configured midiLFO to output midi on channel 16.
Although I am not sure where midiLFO signal actually goes (back to global Nanostudio? Or into sends?).
I'd expect that the signal pipeline will end up in "Sends", so I added a MIDI-Send toward the second track (with the instrument/AUv3) that has the Filter-cutoff that should be mapped to the midi signal from midiLFO.

I had no success.

Can somebody guide me through the steps/logic to make this work, or let me know if this type of routing is even possible.

    Sorry, but it’s not possible in NS2 and there’s no workaround.

    Some things can be done by routing the midi out to another app like Streambyter and then back in. Unfortunately this won’t help with what you want to do because NS2 doesn’t support any kind of cc in or out of AUv3 plugins.

    If you’re interested in how to “bounce” MIDI out of and back into NS2 for other purposes, see here: https://wiki.audiob.us/doku.php?id=auv3_midi_recording_workarounds#nanostudio_2

    But unfortunately it won’t help in this situation.

    You should be able to run midiLFOs standalone outside of ns2, then map that to one of the macro knobs to control some things.

    It’s been so long since I’ve tried that I forget how to midi learn those macro knobs though. 😬

    Ah nice! I tried with Audiobus loading midiLFO ans that works good on Obsidian!
    Although I usually try to not rely on a mix of multiple DAWs for a single project, using another host is a bit uncomfortable.

    Actually I am now wondering why is not possible to route midiLFO output; wondering whether the midi routing works at all (maybe supports sending notes only? 😢).

    Wait, I do this all the time if I'm understanding this correctly:

    If you put your LFO on the midiFX slot, CCs 1 through 12 will control the pitch bend, mod wheel, 8 macro pots and the XY pad. So as long as you map one of the pots or the XY to the filter cutoff of the instrument, it will control it for you.

    Here's a little video demo: https://streamable.com/m84ofg

    edit: That's a completely blank new project so there's no special midi routing being done, just popped in mLFO and told it which CC to send.
