Still fantastic

I remember using this app nearly a decade ago. I downloaded it recently to use my iPhone to control buried parameters on my HX Stomp and Boss VE-500 vocal processor. I use it when setting up for a gig (to adapt to the venue). It works flawlessly with the Apple Camera Connector. The editor on Mac also works flawlessly, and transferring layouts from Mac to the iPad/iPhone takes 5 seconds over WiFi, no hassle at all, no cable needed, always works. Super customizable too. Thank you for this! Hopefully my review will help others like me who were unsure if this actually still works. If you need to control MIDI using your iPhone/iPad, it doesn’t get any simpler than this!

I have a lot planned between this, my modular and installations with Renoise among others.. Renoise has that OSC / Midi internal server. Which is great. Easy to really connect. My ONLY PROBLEM as I can’t review the other release.. was thinking eh.. separate programs? Common. I mean, sure, BUT give us supporters and previous owners (& lovers) of the app a little break and I would buy it 100%.

Difficulty connecting to Mac/Mainstage

I found the process getting Touch OSC to work with my Mac running Mainstage very challenging and took many steps including downloading 2 other apps on my Mac to make it work.

Even then it only worked 1/2 of the time and was always quite the process to get Touch OSC to connect with Mainstage on my Mac.
