MIDI Wrench

Just wanted to see the plain midi signals. Midi keyboard was recognized at once (M audio keystation 61) Thanks- great app

Hey there is no audio when pressing the piano keys Can you please fix it

Sometimes just opening this tool can resolve MIDI connections. If you use MIDI, you should keep this app handy. Anytime I have MIDI connection problems or I want to know what data is being sent and from where—this is the tool I use. You can stop and restart MIDI message flow and lots more with this tool. If MIDI activity is a mystery to you, this is the tool that reveals what’s going on “under the hood.”

It simply does what it’s supposed to do. Not a bunch of junk needed like some other apps. THANK YOU!

This app is so fantastic at what it does that I wish it was designed to do just a tad more because then it could really be the MIDI ‘Swiss army knife’ so to speak, not just a “wrench.” If you use your iOS device with any MIDI I/O especially multiple types simultaneously like hardware MIDI I/O via USB or bluetooth/Wi-Fi MIDI, virtual MIDI, various apps simultaneously that use MIDI this app is incredibly valuable because when something isn’t behaving the way you’re expect, getting to see in realtime line-by-line each MIDI command you can quickly figure out what’s actually going on and adjust that to meet goals. There’s a a few knobs (4) which have plenty of versatility in that you can configure them to any MIDI channel or CC desired , its a bit weird to me to see just a bit of that type of functionality - but in a way it makes total sense and I wouldnt’ wish them gone. I was hoping maybe it could work as a MIDI patchbay - it has this one feature which will “echo” all inputs to outputs but it says that’s meant for measuring latency (very cool) but it would only work for MIDI routing in the very specific cases. Great free app.

Is it possible to add options like (1) change the range of keys and (2) set the keys to different scales. It will be nice to control a vst on the desktop from the GarageBand with this app or similar set as an auv3 instrument. I am trying to use an iPad as a midi controller for the vst on a pc using Bluetooth midi. Thanks for creating a great simple app but maybe additional options can be sold as in app purchase.

This is exactly the tool I needed to diagnose the problems I’ve been having getting MIDI data transmitting properly between my iPad Pro and my Windows computer over rtpMIDI. Thanks so much!

Everything is quick, lightweight. Looks like 4 midi controller ‘knobs’ which (normally I hate on screens but) each knob graphic expands to full screen & it feels so smooth like butter… I dunno, if something goes wrong I’ll change my rating but off the bat, this is like “wow what a nice tool” & it’s free? Thanks so much

sound would help with testing. i see signls but hear nothing.

My go to midi app. Just work
