Floor pod plus midi interfaces
by Motters on 2012-10-31 12:51:09.6750


It would seem there are some midi interfaces that do not work to well with the Vyzex editor.  Is there any knowledge base of interfaces that do or dont work??

I am looking to buy a chord usb interface is there any info about te compatability of this kit.

Thanks Motters

Hi Motters,

We've covered this quite a bit on other threads, but here are the basics:

  1. All software editors (all of them, not just the Vyzex and Vyzor editors by Psicraft Designs) use two-way SysEx messaging to communicate with hardware instruments.
  2. Unlike note and CC event messages, SysEx messages are more than 2 or 3 bytes long. They can be hundreds or even thousands of bytes in length depending on what information they are carrying.
  3. Budget MIDI interfaces are often only good at relaying messages up to a certain length before they start failing. Really cheap ones can't handle messages longer than 32 bytes long for example.
  4. Because notes and CCs are so short, such budget interfaces appear to be completely reliable for normal sequence data, but exhibit all kinds of problems when required to relay messages between a software editor and a hardware instrument.
  5. At the time of this post (Oct 31, 2012 *happy halloween, everyone*), the USB MIDI interface market has been flooded with cheap USB MIDI cables - Not many of them can handle SysEx reliably.
  6. A number of very high quality USB Audio interfaces have an add-on MIDI port. Surprisingly, these can be comparatively low quality to the audio side of the product and may have the same limitation as a cheap USB to MIDI cable interface. You'll need to check first.

So in answer to your question, here are MIDI interfaces we know to be 100% reliable with our editors:

  1. Roland/Cakewalk/Edirol USB MIDI interfaces with the letters UM in their name.
  2. M-Audio MIDISport and UNO USB-MIDI Interfaces.

Beyond this, it is up to you to use your best judgement and be ready to return any interface that fails to meet the editor's requirements. I will say however do not try using any of the EMU/Creative USB MIDI interfaces with the editor because they simply do not work well with SysEx. Given EMU and Creative's history this is very surprising to hear, but unfortunately it is the truth.

Good Luck,

Hi Tony

Many thanks for your comprhensive and helpful reply.  The sensible thing to do would be to buy one that is known to work.

Thanks again

No problem Motters.

It's been brought to my attention in another thread that the M-Audio UNO does not have drivers available more recent than those for OS 10.6.8 - This is unfortunate, but probably only a momentary disconnect as M-Audio transitions between being owned by Avid and being owned by InMusic, who are the parent company of Numark, Akai Professional and Alesis (to name a few).

If anyone is looking for an interface with the latest Mac OS support, my advice is to go with the ones made by Roland.

The specific driver info and download page is currently here if you want to check any model out:


The information above may not be current, and you should direct questions to the current forum or review the manual.
