Okay, let me repeat back to you what I understand to be the
issue. Correct me if I'm wrong:

When you select a Variation Effect in the Logic Environment the
AN1x expereinces a midi buffer overrun error and does not
automatically change to the new Effect. However, you CAN alter
Effect parameters from the Logic Vari Environment layer channel
strip(s) ∗if∗ you've pre-selected the Effect on the AN1x. Correct?

Since this specific environment layer relies almost entirely on
SysEx it's not surprising that you would experience an error at
some point. Using SysEx for real time adjustments is a dodgy
proposition on ANY synth as SysEx consumes much more of the
MIDI bandwidth then simple MIDI CC messages. The fact that
AN1x SysEx packets are large (by design) to begin with does not
help matters. I would strongly recommend you disable FAST
Mode on the Unitor. This may be USB related issue but
considering the track record of success, in general, AN1x users
have experienced with Emagic MIDI Interfaces this is the best
place to start.

I've been running an Opcode Studio 128x in MTP emulation
mode for months and have had minimal problems with SysEx,
Logic and the AN1x. If I find the time this week I'll try to switch the
Studio 128x into FAST mode instead and see if I can recreate the
failure you report. I suspect I may have to fall back to using OMS
w/ Logic Audio for FAST Mode support.

Jon
