MidiFire is a free-form, modular AUv3 MIDI effect host, CoreMIDI router, processor, monitor and clock source from the makers of MidiBridge. Drop and arrange MIDI ports and modules onto the canvas however you like and connect them up to start routing and processing your MIDI events. Pan, zoom and scroll the canvas. Add as many ports and modules as you wish. Connect them in series or parallel. Cascade them together. Merge and split. You can create highly complex MIDI processing setups. Or keep it simple - the choice is yours. ▶ FEATURES Essential processing modules for channelising, filtering, transposing, 'monofying', remapping and monitoring - or create your own. All included with the standard app. A highly accurate remotely controllable MIDI clock source. Save your work into recallable/re-usable scenes. Share your scenes with other devices, computers and people. Switch between your scenes via configurable MIDI program change messages. Download even more functionality within the app for free using the 'Scenes Club' for useful and special-purpose scenes that you can incorporate into your workflow. Initiate and connect Bluetooth MIDI sessions within the application. Define multiple virtual CoreMIDI ports to segregate your MIDI streams. ▶ COMPATIBILITY MidiFire supports all CoreMIDI hardware interfaces, the network interface, virtual ports (self owned or other apps') and Bluetooth MIDI. Also available for mac on the Mac App Store. Scene files are interchangeable between iOS and macOS. ▶ STREAM BYTER (II) What sets MidiFire apart is the newly extended Stream Byter module first pioneered in MidiBridge. With this you can write your own processing modules using textual rules. Newly added constructs to the Stream Byter include: IF/THEN, local/global variables, mathematical functions, timing variables, 'onload' rules, setting of block labels and sending arbitrary MIDI data. The Stream Byter is backwards compatible with rulesets you already have from MidiBridge; just copy/paste them in. ▶ NICHE MODULES Also included are some specialised modules: • Tracking Clamp - reduce tracking miss-hits from MIDI guitars. • Robotic Knob - generate complementary CC messages to control synths and FX based on your playing. • OSC Exchange - send and receive OSC data across a MIDI channel (DIN, USB, wifi or Bluetooth) between MidiFire instances. ▶ FURTHER INFORMATION For tutorial videos, full manual and more, please visit the MidiFire website - http://midifi.re For assistance in writing Stream Byter rules please email us or join the 'Audeonic Soapbox' forum - http://soapbox.audeonic.com and post your requirements there. * Powered by the MidiBus library.

MusiKraken is a modular MIDI Controller Construction Kit, empowering you to fully harness the capabilities of your mobile device's hardware. Winner of a 2022 MIDI Innovation Award! Make music using device sensors like Touch, Motion Sensors, Camera (face, hand, body and color tracking, including TrueDepth and LiDAR support) and Microphone, or connected devices like Game Controllers, Apple Watch or AirPods. Choose from several types of modules in the editor and connect the ports to create your own personal MIDI controller setup. Route the MIDI signals through effect modules to control multiple instruments simultaneously or invent creative new MIDI controller combinations. MusiKraken supports sending and receiving MIDI data over Wi-Fi, Bluetooth or via Core MIDI (for example by using Inter-Device Audio and MIDI (IDAM)). And it can host Audio Unit (AUv3) instrument plugins. Or send the sensor data via OSC. MusiKraken is also one of the first apps to officially support MIDI 2.0! You already own a very powerful device with all kinds of sensors and connection possibilities. With this app you can use these sensors as inputs, combine them with all kinds of MIDI effects and send the resulting MIDI events to your computer, synthesizer, any other MIDI-capable app or Audio Unit to to create your own, expressive MIDI controller setup. Your device for example has a multitouch screen. Use this with the Keyboard module to slide on the keys to control multiple musical parameters simultaneously. Using MPE, MIDI 2.0 or the Chord Splitter also allows you to control these parameters separately per key. Newer devices also support tracking the finger radius (or pressure on older devices), which adds another dimension of control. Multitouch is also used by the Chords Pad to play the chords of a selected scale, or the Touchpad, which allows you control values via touch gestures. Another unique input sensor is the camera: MusiKraken supports tracking your hands in front of the camera, your body pose, your face or objects with specific colors. This way you can for example use your iOS device as a Theremin, jump or dance around in front of the camera to generate notes or control audio parameters, use your mouth to control the sound of a virtual trumpet, or any other combination. If your device has a TrueDepth or LiDAR sensor, you can also use the distances as input values. Your device also has motion sensors: Accelerometer, Gyroscope and Magnetometer. They can be either used separately, or combined to get the current rotation of the device in three dimensions. Use this to generate sounds or control parameters while shaking or tilting your device. Your device also has a microphone, and MusiKraken can detect the pitch or amplitude of the signal. Your iOS device also allows you to connect to external devices. MusiKraken for example supports Game Controllers (trigger events on button or thumbstick changes, motion sensors, haptics and light on supported Game Controllers), Apple Watch (motion sensors, digital crown, touch, heart rate) or the motion sensors within AirPods. The real power comes once you start combining the sensors with the effect modules. There are effects that can be used to change or filter the MIDI events. Some effects allow you to combine multiple input sources into new output values. Or splits chords into separate notes so that they can be sent to different channels. Important: Please note that some of the modules only work on iOS devices with specific hardware: ARKit Face Tracking and the TrueDepth module need a TrueDepth front camera, and Hand and Body Pose Tracking needs at least iOS 14, and might be too slow on older devices. HealthKit is used in the app to access Apple Watch data like heart beat or motion sensors. The app only uses sensor data to generate MIDI events.
