After several lengthy emails with Helicon support over the past 2 weeks, I have found out the problem with the update posted.

It seems the issue is with "modern" MIDI interfaces in that they are too fast for the Harmony M interface to properly load the data.

I have today obtained the Harmony M build 18 update and applied it to my Harmony M and so far so good.

I am using the Edirol UM-SX1 interface with MIDI-Ox, but Helicon techs also recommended a couple of adjustments in Midi-Ox as well.

These are to:

Set Low Level Output Buffer to something very small like 32 bytes...

Set 100 MilliSeconds Between buffers and F7s.

Be prepared, using this method it takes about 12 minutes to do the upgrade.

In my case I didn't really care about the other stuff in the upgrade, but I DID want the near 60% increase in chord recognition when driving the harmonies from a keyboard. Very important I felt.

I have asked if it is okay to pass the build 18 file along to others, and I am awaiting their response.

Although as I have advised Helicon it works, they may very well post it to their website.

Just a heads up for you guys.

Cheers

Dennis

PS: Midi-Ox is reasonably user friendly, but if anyone wants a "step by step" on making the adjustments, let me know.

I had another email from Nicholas at Helicon.

He has advised it is okay to pass on to other users the new update patch build 18, which will take your harmony M to version 1.8

In fact he is hoping owners will, so they can get more feedback on the patch working on other systems.

I ahve applied it to mine and it works fine, AND the chord recognition IS much quicker.

Anyway just thought I would let M users know.

Thanks Dennis--Good post.

Adimatis, that is not the latest release.

It is now build 18. Helicon have not yet posted it to the website

So that link does not point to that file.

Miden, will you please send the version 1.8 to me?
Thanks,
DonM

Send it to me as well. Additionally, is there any way to do the update of the OS without having to purchase an expensive interface device?

Gary

Dennis - if you please, send the build 18 update to me also. Thanks,

Cass

Hi guys, yep I sure will...

But please refer to the original post for the settings advise by TC Helicon for Midi-Ox.

Dennis

Gary, ANY bog standard interface will do.

Also it IS important to set Midi-Ox (free download) to the settings I mentioned in the OP.

And be prepared, it WILL take around 12 - 15 minutes to complete.

Dennis

PS.... All you guys now have mail
