Solid App, Needs Some Polish

This is an incredibly useful app. It works great for designing templates and triggering MIDI commands from a custom layout. It needs some polish though. Lots of little annoyances are present, like screen rotation issues, a clunky app interface, and a companion layout design app that has been neglected for years. Overall, I would 100% recommend this app. I just wish the developers would put a little more time into cleaning up the user experience.

Bravo! This is the missing link

At least it was for me. Somewhat obsessed with midi controllers and had been tweaking a live loops set up and for some time just always had that 1 button or command that I didn’t want to have to press. I have had like 5-6 of the more well known midi to daw controllers (notation, Akai) and still use those plenty.

But this app magnificently does things that none of those controllers can do. This helped me creatively, technically and now I have a lot more flexibility to do more interesting thing in my sets and continue the exploration.

I have never written a review before - this app is a must have if you do anything with MIDI

Not giving up yet 😂

I’ve been at this TouchOSC for a few days now, created custom layouts with Toggles, Rotaries, Push Buttons , Faders, XY Pads and Multis to use for virtual instrument libraries within Logic Pro X, Kontakt and other plugins. I am getting the hang of it.
Though, it seems that, using TouchOSC over a network connection at times chokes up notes on MacBook Pro 2015 with 16 gigs of ram and SSD Drives. Need to do more trouble shooting with TouchOSC & Osculator. I am thinking maybe Osculator is the culprit here.
It would be nice if Hexler would make TOSC USB capable as well.
Other than that I like the TOSC. As mentioned in other previous reviews, it would be nice to also have more choice for colors and graphics.
