Using multiple MIDI-in sources - can you now select the incoming MIDI port?

I think you're right, this thread has had over 200 views in a short time - Clearly an issue people are interested in!

Be really interesting to have a play, **** work!! 😟

mate i have another quick question

When i record in Logic X , recorded waveform shows L/R sepatate like in Protools , while it is showing single waveform during recording .

is it possible to change it ?

Hi mate, If you hold down Alt and scroll your mouse wheel it should close the track heights down, at a certain point it will stop displaying seperate L/R's.

Does that help at all? Can't remember seeing an option on how the waveform displays other than that.

yeloop, yes you are correct, i have a midi drum controller which i cannot set the output channel - so i've always used it in this way.

If you want to go direct to the instruments on a device level then would doing the following achieve what you want?:

1. Make sure the tracks you want to control exist (In this case i've created a bass and piano track):

2. Go to the environment window

3. Mixer view should be displayed by default within the environment window, if it's not selected, then select it from the layer pull down menu:

4. From the NEW menu, select 'physical input' this will display the midi ports for you to connect to in mixer view.

5. Now, first thing is to remove the sum of all ports being transmitted to the sequencer. So either right click and select 'Eraser Tool', or press 3. Then use the eraser to break the cable coming from 'Sum'.

6. Go back to the pointer tool (or press 1) so you can connect your ports directly to the instruments in the mixer view.

7. Now connect your ports to the instrument strips that you wish to control, and bingo!

I hope that gives you what you want? Just connect the cables to each instrument as you work through your session.

Once again, it looks a long process written down, but it truly isn't.

Just to add to the above, you can bypass removing the Sum cable (5) and go straight to 7.

If left connected any unassigned ports will control all record enabled tracks as before, meaning that you can break connections you make, and when joining new connections they will be specific to that port.

Top of the waveform is L, bottom of the waveform is R. Beyond a certain vertical zoom level they snap to double lanes (new in LPX).

(The same audio file on both tracks, both tracks stereo. Audio 1 is slightly more vertically zoomed in (=higher) than Audio 2.)

Hi Mate,

There's probably multiple ways of achieving this, the simplest (And what i would use) would be to select 'Use External Instrument Plugin' in the details section when creating a new track, and from within that plugin you can set the outputs (i.e. which midi instrument you're controlling and the port).

It will appear just as a soft instrument in the environment too so you can plug in to it as discussed.

Just Note that the Input selection within the External Instrument Plugin corresponds to an audio In on your audio interface, this is if you wanted to bring your external midi instrument in on a spare input and have it's signal processed like a soft synth - It's not relating to Midi Input, so don't get them confused.

i.e. you don't need to select anything here if you're not running things that way, if you are it's a handy little option to have as it prevents having to create an additional Audio track to monitor.

Hey mate

So now we made the connection , it is working . When i select another instrument on my sequencer , selected channel plays the selected instrument . That works

But now, there is another problem .

How can i record the midi data coming from external sequencer into logic on different channels ?

As we took the cable from transformer right into the channels , we have to go back to the sequencer input back to make logic record the midi data .

But now, different datas getting recorded on all instruments , not separately .

res4, i had all sorts of problems at the weekend when recording, i'm not sure if there's not bugs there you know?

For example, i set my midi devices to transmit on seperate channels and set those channels on the tracks - But it was really random, sometimes all the instruments would play from one keyboard, other times only one would play, and somtimes none of them played.

It got me really frustrated - As i got my keyboards on a 2 tier stand i like to play bass notes and lead at the same time from different keyboards.

I really need to spend some time sorting this out, i've decided i'm going to put it up on a website with a list of other issues that i've noticed get repeated here a lot - That way a definitive guide will be available for everyone.

Please look at the photo .

Physical input represents my external analog sequencer .

So 6 channel of the sequencer is able to play 6 different software instruments without getting mixed up.

So until here we achived what we wanted.

What i need know is Logic should record midi data to each instruments individually .

Means if my sequencer playing Software Instrument 1, i want to record incoming midi data to the instrument's channel on the arrange window.

To be able to record incoming midi data, we need to cable also to the Sequencer Input of Logic

(at this photo, physical input directly connected to the channels and not to Sequencer Input of Logic)

What i thought was to take again cables this time from instrument channel and cable all of them into Sequencer Input

When i do that, it doesnt work .

It records, but lets say, recorded midi on Software Instrument 1, playing all of the rest at the same time again.

Now, there must be a trick, which if a software instrument is armed for recording, it should only record midi data from what it comes to this channel from external hardware sequencer .

Analog Sequncer channel 1 should record midi data to Software instrument 1

Analog Sequncer channel 2 should record midi data to Software instrument 2

In another words, if analog sequencer channel 1 is playing , but in ,logic lets say Instrument 2 is armed for record, it shouldn't record the midi data of Analog Sequencer channel 1

We have to cable to Sequencer Input this is for sure to grab the incoming midi data , BUT there must be something in between to route incoming midi data to Sequencer Input so in recording, midi datas should not be mixed up .

You understand what i mean ?

I don't think you will not be able to record this way. (Do you have "Auto-Demix by Channel" selected in Logic's Settings/Recording tab.) At least that's the name in Logic 9.

You have to use the Environment Channel Splitter method where the Port is run into the channel splitter and output channels are run directly into Instrument Objects then into the Sequencer Input.. at least I think that's the order. It's been a long time.

Selecting individual MIDI ports was something I thought Logic X would have... it's very much the same program at it's base but with a lot of nice additions and re-worked areas.
