Thanks for clarifying the 1 MiB limit. Reducing our SDK working-buffer request to 240,000 floats resolved the original loading problem, and we’ve since developed several functioning custom effects.

One follow-up: is that 1 MiB allocation independent for each Endless effect, or does it share memory resources with other effects running on the MESS?

I’m asking because I’ve experienced repeated freezes when saving presets containing a custom Endless effect alongside factory effects. The custom effect alone saves successfully, but adding another effect has sometimes caused the MESS to freeze during saving.

I’m using firmware 1.3 Beta 1. Could this be related to memory management, or would you prefer a separate bug report with reproduction steps?

> Mess Firmware 1.3 Beta #2 Here is the second beta for Mess 1.3, with fixes for saving and loading presets containing Endless effects. CHANGES FROM BETA #1 Fixed freezing when saving presets containing Endless effects. Fixed the selected Endless patch not being reloaded when switching presets. The patch selection is saved per preset and restored when that preset is loaded. When an Endless patch fails to load, “Not loaded” is now displayed instead of the patch name. ENDLESS EFFECTS IN…

Thanks to everyone who tested Beta #1 and shared feedback!
