Some footnotes:
(1) Re: the Extension Interval bug
---- After extensive testing, I concluded (at least until I discover otherwise):
-------> The Extension Interval is correctly saved when a preset is saves.
-------> The Extension Interval is not correctly restored when a preset dialed up.
-------> The actual Extension Interval is inherited from the previously loaded preset.
---- This issues has been discussed in the P2K group.
-------> If you want to real all the threads and posts, search for "Extension Interval"
-------> Or, read this: https://groups.yahoo.com/neo/groups/p2k/conversations/messages/14998
---------- I basically confirmed what Bruno discovered--inheritance problem and one work around.
-------> A variant of Bruno's work around:
Bruno suggests having preset pairs and switching from one Ext Int preset with the desired value (= 12 for example) to another. Evidently this work around also works by recalling the one preset via midi twice (based on tests with a keyboard that can send Program Changes.
---- One of the Command Station Addendums says this bug was fixed on the CS/P2500. I will test that.
(2) Re: The missing FEnvTrig patchcord destination
---- Its missing in the display of both the 1 ru E-mu and the P2500
---- As a followup to the "maybe it can be done via sysex parameter change" comment:
------> At some point, I would like to test for that as well as other destination numbers.
