Ooooh, duh! I get it now... :-P

You are literally changing the Delay Time parameter while
recording aren't you? Okay. Then the AN1x is indeed transmitting
a SysEx stream to Cubase - and Cubase is dutifully recording
the information and playing it back. If you go into Event List edit
mode for that track in Cubase you'll see the SysEx stream. I
created a simple AN1x and Drum Loop sequence in Logic Audio
and recorded changes to the Dly time parameters to confirm this
behavior.

Here's the deal - - SysEx messages for ANY synth are
considerably larger in size then MIDI CC events consequently
they eat up ∗much more∗ bandwidth. When transmitting SysEx
streams to any synth it stands a much better chance of success
at slower tempos - the AN1x chokes easily on SysEx streams to
begin with so it's no surprise to me that your AN1x is being
overrun. (This is why I find it preferable to use MDI CC, RPNs,
and NRPNs over SysEx.)

I'm not certain why you feel it necessary to alter the Delay Time
settings in real time but no doubt you have a reason. I would
offer two suggestions as an alternative towards achieving
similar results: 1) Stick with altering thr Delay Depth setting as
mentioned - you can create wicked dub type effects - or - 2) Use
the TempoDly instead which will allow you to sync to MIDI Clock -
the delay time will then follow tempo changes in your Sequence
(I assume this is what you are after?)


I'll repeat myslef - IMO the performance you experience with your
set-up will benefit immeasurably with a proper, multi-port MIDI
Interface. Since you're already using Cubase I'd suggest you
scope out their current product line. Unless I'm mistaken, their
MIDIEX 8 model offesr some type of proprietary time stamp
technology similar to those offered by Emagic (AMT) and MOTU
(MTS). This would be beneficial in a kit with multiple hardware
devices. Otherwsie, you'll probably get by just fine with their little
2x2 model...
