## What is Midiflow Motion (Audiobus)?

This MIDI sender app for Audiobus 3 lets you control effect parameters of other apps – in a way that no touch screen can replace – by moving the device. Set any kind of MIDI command like volume or modulation as output and fine-tune it to the exact motion range you want to perform with. You can even control multiple effects simultaneously.

+ Use device rotation around the X or Y axis
+ Adjust the range of motion for controlling a parameter
+ Adjust the range of output values
+ Send virtually any MIDI command (e.g. pitch-bend, any Control Change like modulation or expression, and even custom MIDI messages)
+ Control multiple parameters and/or multiple apps at the same time by inserting this app multiple times in Audiobus

NOTE: This app requires Audiobus 3. Insert it into one or more MIDI sender ports to control the synth apps in the MIDI output ports of the respective pipelines.

THE IPAD IS YOUR CONTROLLER
Without a doubt, the iPad's touch screen is a revolutionary tool for musicians. However, it also comes with sensors that can track how you move your device around two axes. Using those sensors to control effect parameters allows you to perform with a huge amount of expression.

CONTROL ALL KINDS OF PARAMETERS
Many synth apps allow you to "remotely" control their parameters via MIDI messages. For that purpose, Midiflow Motion can send virtually any MIDI command to those apps, through Audiobus. Just select from the list of available parameters and the app starts sending messages when you move the device. Not only can you use basic Control Changes for "volume" or "modulation", you can also use double-precision commands (LSB + MSB), RPN/NRPN commands or custom MIDI messages. If you want to play notes, you might want to add Midiflow Scales behind this app in the Audiobus MIDI routing in order to map the notes to a scale.

ADJUST MOTION RANGE
The range selector at the bottom allows you to narrow down the motion range in which you want to control the parameter. The maximum range goes from -90 to +90 degrees. Use either the slider or the learn buttons to adjust the range according to your needs.

CONTROL MULTIPLE PARAMETERS
You can insert Midiflow Motion in Audiobus multiple times. That way, you can send multiple MIDI commands simultaneously. Each of them can be configured independently. For example, you can control the cutoff of a synth by rotation around the x-axis, and use the y-axis for the resonance parameter. It is like an x/y-pad, but with the whole iPad as the controller. You can also control parameters of different synths at the same time.

## Key features

- Control effect parameters with device motion
- Use device rotation (X/Y axis)
- Adjust motion and output value ranges
- Send any MIDI command (pitch-bend, CC, custom)
- Control multiple parameters/apps simultaneously
- Integrates with Audiobus 3

### 4/5 — Revolutionärer MIDI-Controller mit Kinderkrankheiten

*2019-11-27*

Die App zusammen mit der Midiflow Scales App als MIDI-Controller für Töne zu nutzen, ähnlich einem Theremin, ist eine geniale Sache und revolutioniert meiner Meinung nach die Art, Musik mit dem iPad zu machen. Leider stürzt sie bei mir in Kombination mit der Midiflow Scales App andauernd ab (iPad 7. Generation) und lässt sich daher live nicht einsetzen, was sehr effektvoll wäre. Daher nur 4 Sterne, ich hoffe auf ein Update, da diese App eigentlich eine wirklich geniale Arbeit ist!

### 3/5 — Audiobus

*2019-03-14*

Brauche ich Audiobus 3 oder reicht auch 2

**Developer response:** Ich verstehe die Bewertung leider nicht. Schade...

### 2/5 — Seems great, but no documentation and responds to random midi messages

*2018-06-24*

Seemed like a really cool app, a little unintuitive at first but after watching the videos it’s clear how you have to set up multiple instances of the app to control multiple different parameters. Which is silly, the ape series of apps has extensive motion control mapping without being hosted several times.

Furthermore, the app kept responding to random midi ghost LFOs even though it wasn’t set as a destination. Very confusing series of apps with little documentation for how long Midiflow has been around.

### 1/5 — 1 Star

*2018-06-16*

Developer has capitulated to the scourge of the GDPR without explanation of update. Sad.

### 5/5 — So awesome!!!

*2017-04-07*

It's so awesome, that I can't write a long review, because I NEED to get back controlling the Animoog with the and Fugue Machine, hook up and test more Midiflow tool! 100% recommended, best buy the pack!
