Sorry to be so slow to reply. I chose the digest delivery option, and I have only seen it now, Friday about 1 am.

It seems that it effects all the virtual instruments, so that you select the sound and effects that you wish to hear,
Midi info is sounded as the requested tuning.
It works live as you play a midi keyboard: without the slides, glitches, and delays that I have found with pitchbend systems.
The midifile in the sequencer contains no pitchbend info. as far as I can see.
Many someone with better tuning measuring gear than I have (Peterson - VS-1), can give us a report on the accuracy of the audio output.

For me, as a Logic user, it make my life much easier, as I can now get microtuned output without the tedium of having to tweak every note of every instrument using their sample player (EXS24)

In the perfect work I would have liked it to have MIDI tuning dump resolution with any frequency assignable for any midi note.

Since the controls are in the song preferences, it seems that you are stuck with the twelve note tuning of your choice for the complete song.
Maybe for tuning changes, or more than 12 notes, you need to start another song, and then edit the audio files together after you have bounced them, as you do your audio mix.
As it is set up it seems that you cannot play both EMajor and F minor in the same song; as the tuning for the Ab/G# is set by your choice in the song preferences.

I have added some thoughts on this and more details at:

http://www.lucytune.com/midi_and_keyboard/pitch_bend.html

The HMT system seems to be a "fudge" which analyses notes in a chord and then retunes in repeated attempts to produce (JI-type) integer ratio "pure?" intervals, i.e. naively aiming at zero beating.
Maybe they could extend their application to aim for tunings other than JI?

Their site is amazing.
It claims that their system can work well, and to adjustable levels of change, with other instruments playing in 12tET.

see http://www.hermode.de/

Their perspective seems to be pretty backward-looking.

They appear to be aiming to reproduce baroque tuning;
rather than exploring new possibilities and offering opportunities for adventurous musical experimentation.

My guess is that the HMT function will become a tweak toy for the "blockheads" for a season or two, and eventually fall out of fashion, as listeners hear the mishmash of beatings that result.

It might serve well to open new ears to the importance of appropriate beating in tunings; which would be a move in the right direction.

The microtuning capabilities of Logic 7 may be fairly primitive at present, but Apple seem to be making good progress with their recent multimedia (music and video) applications.

Logic 7 is a good (although slightly muddled) start; at least someone in the Logic team has heard of microtuning and is beginning to understand it.

Let's hope later versions of Logic will provide even better microtuning capabilities.

No problem. Take as long as you need.

Too bad, but much better than nothing!

Again not ideal, but it could be worse.

Interesting. . . I'd love to know how this works.

Another "gotcha", fortunately with a workaround.

Yes, their site and their system are both amazing.

>Their perspective seems to be pretty backward-looking.

Your opinion.

I don't know how "baroque" 5-limit adaptive JI is. Certainly
HMT is enabling the first glitch-free realtime keyboard instruments
that manage comma shift in a reasonable way. Meanwhile, 12-notes
of LucyTuning is decidedly pre-baroque.

It doesn't seem to be a problem playing guitar with piano, ensemble
with piano, etc. etc.

Indeed.

What do you mean by a mishmash of beatings, and why do you think
people would object?
