Midiflow Motion (Audiobus)

Control effect parameters in other music apps by moving your device. Fine-tune MIDI commands like volume or modulation to your desired motion range for expressive control. Supports multiple parameters and apps simultaneously through Audiobus 3.

Highlights
  • 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

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.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
