What's New in MIDI Wrench

1.4

May 5, 2020

This update adds the following new features: • Support for new iPhone models (e.g. iPhone 11 variants). • MIDI channel for virtual on-screen MIDI controls is now configurable. • MIDI events monitor may now be paused (either by new pause button or by long-tap context menu). • Added optional filter for MIDI RT Clock events. • Added support for sending MIDI Program Change commands. • Added support for sending MIDI Real-Time Messages (Start, Stop, Continue, Active Sensing, Reset all Receivers). • Added support for sending MIDI Note Pressure (Polyphonic Aftertouch). • Added support for sending MIDI Channel Pressure (Monophonic Aftertouch). • Added option for forcing the app to continue running in the background (i.e. to capture MIDI data on MIDI events monitor while working with another audio / MIDI app in foreground). • iPhone: MIDI events monitor may now be cleared by long-tap context menu. This update also fixes thes following issues: • Fixes issues with the graphical user interface (iOS 13). • Fixes graphical issues with some older iPhone models. • MIDI event monitor: MIDI channel numbers are now displayed starting by 1, as commonly expected in MIDI world (not by 0 as actually on technical level which was apparently confusing for many users). • Fixed some MIDI SysEx messages not being displayed correctly with certain Bluetooth LE MIDI connections. • Fixed issue with touch events on lower edge of screen (iOS 11 and higher). **NOTE**: The previous clear button had been replaced by a pause button. You can find the clear function now from the context menu (popup menu) by long tapping onto the MIDI events monitor. That's it for now, thanks for your feedback and take care!

Nice little app

Nice app, does exactly what it advertises. If I could magically make additional features appear, it would be the option to display the raw midi message in their hexadecimal form, and an option to manually construct and send midi messages, both in raw hex form and in a simplified version. Those would help with troubleshooting difficult equipment.

LISTEN UP, IT PLAYS NO SOUND I REPEAT NO SOUND AT ALL!!! 🤬🤬🤬🤬🤬🤬🤬😡😡😡😡😡😡

It's a bummer that the MIDI wrench had no sound. I tried so hard to get it working, but it just wouldn't cooperate. Seriously, take my advice and skip this nonsense! 💔

Good App

Good app but you can’t import .mid files. Otherwise, it does its job.
