Just a few clarifications:
There are no "effect slots" in our nomenclature. The term "Slot" is used in Performance Mode: each Performance has five Slots. We have eight effect modules A-D and X-REV.
Presets are completely independent from Rigs. There is no link between any Rig and any preset in our data model. Presets are not stored/exported/imported as part of any Rig and vice versa. You could even delete all presets on your PROFILER and still load Rigs as today, select effect types, and dial in their settings - so basically work with the PROFILER as you do with other devices, which don't offer anything like effect presets.
Effect presets are already linked to exactly one effect type today. When you scroll through the list of presets, that effect type gets displayed in the right column and after loading a preset its associated type gets displayed in the box on the left hand side.
Presets are just a way to rationalize the data entry by storing type and all parameter settings in one independent file. You could for example store the type and settings associated with "TS808" under this name. But as soon as you load this preset TS808 and tweak the parameters within the algorithm towards a TS9, the information, that "this module is originally based on preset TS808" is completely misleading. The only item in common between that preset and your current setting is the effect type displayed on the left hand side.
The new software revision shown at NAMM won't change those principles. It "just" integrates the two lists of effect types and effect presets into one list. Already today each effect preset is associated with exactly one effect type. In the new software revision the effect presets get sorted and listed beside their associated effect type. Based on feedback we received from our beta testers and during the show I'm confident, that this goes a long way towards a better understanding and more effective use of effect types and presets.
My impression is that you are trying to redesign presets into something completely different. What you really seem to be looking for are more specific/less versatile effect types. I suggest we wait for the new effect selection screen and see how that goes. From my perspective offering versatile effect types plus presets as shortcuts to specific settings is a great combination.
