Works with Roland UM-One MK II
But it was on a laptop computer with no other USB Devices (important)
Fascinating! I had not considered that possibility. I can confirm that it also did not work with my iConnect MIDI4+.
I am currently using four different midi interfaces and the only one that works with the ATG-1 settings manager is the RME UFX midi ports. The other interfaces are iconnectivity midi 4+, Roland/cakewalk UM3, and the Midisport 8x8.
The big issue is Antares philosophy is the ATG Manager software on the PC/ Mac should be able to auto identify and connect with Antares Auto Tune hardware platform ( ATG-1, ATG Luthier kit or Peavey AT-200 w/ AT-200B Breakout box connected to the Computer's 5 pin MIDI interface hardware.
Upon application launch the ATG Manager in the background will begin to poll every possible MIDI connection on the host computer and establish a handshake with the Antares hardware.
However the ATG manager application typically "times out", never locating the correct 5 pin hardware MIDI interface which the ATG hardware is connected.
But the fundamental Problem is a misunderstanding by Antares regarding the number of possible MIDI devices (either real or virtual) that can be found on the typical musician's Computer today.
Forget using one of these
Multichannel MIDI interface hardware and Virtual MIDI Cables (MIDI -Yoke, LoopBe30 ) yield problems with the ATG Manager http://www.soundonsound.com/sound-advice/pc-notes-0
The solution is to disable any virtual MIDI port apps, close all other apps that use MIDI, and use a simple one port high quality MIDI to USB cable (like the Roland UM-One MK II ) to make the ATG hardware MIDI connection.
and read the ATG Manager Manual http://www.autotuneforguitar.com/mediafiles/online_help_records/77_ATG_Software_Manager_v1.1.0.pdf
