Interesting... but takes a great deal of time to learn

I spent over ten hours trying to wrap my head around how this app works. It has a strange help system that is context specific, so you cannot read the help information outside of the context of the various modal environments. Additionally, due to a bug in the help system, it took me a while to discover that some help pages spanned beyond what was shown. The developer insisted it wasn't a bug... which contributed to me giving up and requesting a refund (which was immediately granted). I suspect the program is quite useful… if you can figure out how to use it.

As he has not released a version since I reported the bug: To get around the help system bug, click on another help topic and then click back to the topic you want to view - the ability to scroll will then be available. The developer insisted that I didn’t know how iPads/Macs work instead of investigating my detailed description of the bug, which I found off putting as I worked with Apple prior to the Mac release in 1984 (including pre-release hardware) and have used Macs etc ever since then.

Interfacing to LED Matrix panels

Any suggestions on how to interface with LED Matrix panels that use the HUB75 interface?

I’m currently using both a Teensy microcontroller with SmartMatrix and a Raspberry Pi with an Adafruit LED matrix shield and would like to drive it from the LED Lab app.

Not for the faint of heart

This is NOT a simple program - it will take no small amount of trial and error to get things set up the way you want them - but once you've got it set up, it's an AMAZINGLY rich and flexible resource. I've used it with a Fadecandy-based Neopixel matrix as well as with RasPi-based HU75 matrices (both emulating PixelPushers), and it's been great with both.
(And in addition to that, the author was very helpful via email in working out specific settings tweaks to get me up and running.)

Anyone know how i am supposed to add my own artnet controller?

Tried to figure it out but can’t. My artnet controller is working fine with other software but for the life of me I cannot work out how to add the controller to this software. Each time I click new is says I need to un-sync from my last controller (I didn’t have one). Purchased the software thinking that was the problem, turns out no. Cannot see anywhere manuals, instructions or any step by step guides. Totally lost.

A number of questions about music and Tracks

Hello. I just bought the Music add on and am unclear on a few things:

1) I can see how I can export Scenes as a way to back them up/transfer between devices. Is there a way to do the same with Track listings and the Scenes synced to them?

2) I can set up Tracks and Scenes, but when I play, I never get audio. How do you enable audio to play?

I’m using an iPad Pro 11” on iOS 12.3.1

Is there a better way to get product support? I couldn’t find one on the website.

Thanks!
