Midi feedback with Logic 9

[Trailerman]

Bammer - sorry, can't help you with your meta query, but your Logic feedback routing works great!

Thank you

Glad it's working Trailerman.
If we could figure out the Bang command, we might be able to put a button in Lemur to retrieve all the current parameter settings of the channel strip and soft synths so they would show in Lemur. (unless there is an easier way)

Now that would be cool!! Good luck!

I found a link that sort of describes how to do it. It's pretty deep environment stuff,

http://www.logicprohelp.com/forum/viewtopic.php?t=715

page 2 of that thread has some pretty good info. Might be over my head for now though. lol

You can't bang parameters of a plugin. But what you can do is have a bunch of faders connected from the output of a channel strip. Each fader would be programmed to respond to -- and mirror -- the value of specific parameters that you tweaked. You could then bang those faders and send the values back to the channel strip.

A more elegant (and complicated) way would be to use the mapset functions to set various map values within a transformer in response to the parameters you tweaked in a given plugin. You could then read out the map values at a later time and send them back to the channel strip.

So, in essence, each fader would kind of be a closed-loop system mutually exclusive unto itself. Each fader would feed/bang its respective plugin parameter back through the channel strip which, of course, would send the aggregate of all the fader bangs straight out to Lemur. Looks like a worthy weekend project.

And then here is an S.O.S article by Len Sasso explaining it in some detail --- near the bottom.

The Bang message (#99) is a particularly useful Meta message. When received by any Fader object (except one that's sending Meta messages, for reasons we won't go into here), it causes the object to resend its value. You might use that to send all values from a bank of Faders in a mixer or synth editor you've created. The Bang message value affects the outcome in various ways. If the value is an even number, the Bang message will be passed through the target object — useful when you want to Bang a whole chain of Faders. Values of 121 and 125 cause the Fader value to increment — with and without roll-over — before being sent (120 and 124 do the same with pass-through). Similarly, values of 123 and 127 cause the value to decrement.

I have just set up Bammer's Environment to get the feedback, and it works very well- thanks.

The only problem is that I now have a feedback loop of CC data that is crashing Logic.

Any ideas/strategies, anyone?

I am using:
Daemon Input 0 Receives from iPad Lemur Out 0
Daemon Output 0 Sends to iPad Lemur In 0
...in case that is what is doing it.

HOW CAN I DO IT? THERE IS NO WAY TO SELECT a MIDI INPUT as in other DAWs like cubase. I need your help for LogicX - this is unclear for me here.

I need setup for my Lemur App Composer Tool, I need to to create 2 tracks in Logic
one to send MIDI and one to receive midi
On the first track I need to set the output to Lemur
On the second track I need to send input to receive from Lemur and point it to virtual instrument

I need to recall presets from my Logic DAW from Lemur.
When I press Recall in my Lemur App - Lemur sends out CC127 at max value of 127
All I have to do is to send back to Lemur CC127 but values between 1-126 and by this Logic will recall corresponding preset

I need to be able to modify this what Logic receives - value 127 of CC#127 so Logic when receives such value sends back CC#127 value f.ex 53 on the first track
On my second track I I need to be able to modify this what Logic receives - value 127 of CC#127 so Logic when receives such value sends back CC#127 value f.ex 54


In Cubase I would need MIDI send and midi transformer to this

I need to create track and set its output to Lemur and then tell the transformer to convert CC127 value 127 to value 53. Now when I press Recall button in my LemurApp preset 53 is loaded

Please help how can I do it with ENVIROMENT

I am one step forward, BUT I am not sure how to do it using Transformer
