1. I'm using Isadora 4.1.3. I entered the wrong version in my original post.
2. I checked it with Legacy, and Izzy is not crashing with that version.
3. I'm working with the SmartSuit Pro II. The crash happens when I stream from the suit or from a mocap recording (e.g., no suit). Not sure if that matters.

It's a known cosmetic issue on newer versions of macOS with Isadora 4.1.3 and older.

This is fixed already for the release that's coming very soon.

In the meantime, you'll see that those areas are only blank when you do not have MIDI, OSC, Serial, or TCP/IP data going to or from Isadora. As soon as data is going in or out, the relevant section of the UI will update.

In its simplest form, you can do this to see what I mean:

Here's a slightly more complex example that demonstrates the same thing, but cycles through each of those four data types: DOWNLOAD

(NOTE: The MIDI won't work unless you use the settings shown in the screenshot for Communications > MIDI Setup > Port 1 > (Input and Output set to "Isadora Virtual Out")

hi

i’m toying around with behringer xtouch mappings between different software. Utilising the sys ex send actor i can remap the text of the channel strips on the control surface. The problem is there are only 9 parameters max on that plugin but I want 15 or so. I was going to look at javascripting it somehow. Any solve?

thanks
