There are several instances where I design a sound in an instrument, but it loads differently in Lab V:
Most instruments with filter changes in the preset would load in a different filter state, while the macro would typically show a max value of 1. To solve this, I had to change and save the presets within Lab V with a brightness value of 0.980 or similar number less than 1...strange.
ARP2600: Some tempo-based sequences were eiher wrong timing, or didn't start the sequence. To solve this, I had to change the instrument sequence tempo to double time...weird.
To other users who play live or sell presets....remember to check your custom sounds in Analog Lab to ensure consistency
