Hi!
I need 8in/8out MIDI patchbay/router to get my PC, Capybara, MotorMix, plus keyboards communicate with each other.

I've heard MOTU ones are good.
anybody disagreeing with this?
Can you please give me some advise?

Thanks in advance.

The Emagic amt8 is a great 8in/8out/router interface. http://www.emagic.de/english/products/hardware/amt8.html

I use a MOTU Midi Express XT. Works great. I bought mine used and haven't had any problems with it.

Also, if you're Windows based, MIDI-OX is a handy program regardless of your MIDI hub. http://www.midiox.com/index.htm

I use 3 MTP AV's currently, and am pretty
pleased with them.
FWIW, my experiences with Emagic, and
especially EmagicUSA, have been so very
very bad that I will not consider purchase
of their hardware. caveat emptor...
Also, rather than use the Motu to link the
MotorMix to the Capy, I've put the MM inline
with the Capy, using a couple of merge/split
boxes. The MM is between the Capy and
the Motu. Works fine.

cheers,
Bill

I use Motu Micro Express USB but with a MAC.Apart from getting Free Midi ,Oms and Cubase all configered together it now works well. It's only 4x6 but I can add extra Motu boxes as I need them. What is most important to me is that if I want to use Kyma and have it controlled by a Keyboard then I can do it by pressing the button on the front with out having to bootup Cubase or any other programme in the background.
Motu make great equipment but there customer services leave a lot to be desired. If you need help with setting up or trying something different, they will probaly tell you that there equipment can't do it, but if you try it yourself it normaly can.

First of all, many thanks all of you :)

I have this in mind:

connecting MIDI OUT of Capybara, computer, MotorMix and Keyboard, to IN ports of the MIDI Patchbay/router/merger,
connecting MIDI OUT of MIDI patchbay, to IN of the above equipment,

define setup from my computer (ex: Merged IN1 +IN2 -> to OUT4...)

Can I do this with MIDI Express xt :8-in/8-out MIDI/SMPTE interface/patchbay/merger?

(I assume it's called "interface" because it provides my pc a serie of MIDI IN/OUT ports. Am I wrong?)


Many thanks in advance

The computer itself connects to the Midi express via USB ,SERIAL dependant on which type you get, so it acts as an interface between the computer and other midi equipment, as well as being a patchbay for them and the computer.

If you have a program running in the computer, all of them can talk to the computer at the same time, and it can talk to them at the same time, so the computer can do the routing. But the midi Express can also do routing between midi devices even if the computer is switched off.

In the computer switched off state, the interface can route an input to all the outputs and can merge at least two of its inputs together.

Of cause with the computer on, the right software can route and merge what ever you want.

So the answer to your question is Yes and much more.

Hi Bill,

"Also, rather than use the Motu to link the

with the Capy, using a couple of merge/split
boxes. The MM is between the Capy and
the Motu. Works fine."

I am considering using merge/split boxes with my Motu Micro Express as you are describing. It seems that the motor mix is a bit sluggish sometimes and I am figuring that this is due to Motu. I have never directly connected the Motor mix to the Capy to verify this, tho. Also, it would seem nice to to keep the output of the Motor mix out of the the midi data stream seen by the computer especially when using a sequencing program. Does any body have comments or experience with this.

Thanks,

John

I have been using a MOTU MTP/AV for the past year here and I have the MotorMix going directly into it, and then software routed to Kyma, also connected to the MTP/AV in another channel.

I don't understand why you want to bypass the MM with your MIDI stream. My system works well here, and I have the added advantage of being able to use the MM from Logic/Audio and anything else I write to handle MIDI streams.

Hi Dave,

I am using Logic Audio, also. In Logic, do you have the midi thru turned off for the Motor Mix or Capy. I know at one time I got really sluggish fader action. I would move a fader then it would jump a bit after I let go. There are sysex messages as well as cc messages between the MM and Capybara so I figured they were congesting the midi stream either in Logic or the Micro Express. It has been awhile since I have used the motor mix in this way so I probably need to verify that this is a problem or not.

Hi John,

It has been a while since I actually used the MM in Logic/Audio. I think when I did that I patched the MM so that it no longer commanded the Kyma, but I'm not certain of it. At that time I was experimenting with using the MM for controlling mixes inside Logic, and the Kyma was not of concern to me.

Most of the time, I simply patch the MM to the Kyma inside the MPT/AV control panel, and everything works just fine for me that way. I might be patching the MM input to ground inside Logic then.

But I haven't experienced the sluggishness you describe except when I have a really busy VCP in Kyma. In that case the MM works just fine but the VCP is sluggish in updating its faders and readouts to match.

Dave,

I played around with my setup the other day. The best approach that I came up with at that time seemed to be not to cancel the midi thru function in logic. I set up the Capybara as an instrument. I found, though, that on playback the Motor mix did not respond so I put a patch cable from the Capybara to the Motor Mix in the Micro Express control panel. I could have played with routing in Logic, too. Everything recorded and played back fine including switching banks and randomizing settings. Since I was using the autodrum.kym I did not have note data in the the midi stream to clog things up.

Anyhow, this setup seemed satisfactory for what I was trying to accomplish. Is anybody doing this sort of thing in another way?

John

It is not! I aggree that it works very well together with Logic as far as you don't deal with sysex data from the outside. There is a serious buffer problem for larger sysex messages I found out the hard way. It was later confirmed by Emagic. I would sum it up as 'underpowered' ... longer sysex messages get chopped. The most reliable MIDI interfaces/routers IMO are the Opcode Studio 5lx - but as everybody knows Opcode is a thing of the past.
This is written based on first hand experience. Kyma is connected to a USB driven AMT8 but receives only note ons and controllers - no sysex.

Just a thought. I also have Logic and soetimes run it when Kyma is running but mostly not. I made a small app in MAX whish simply feeds both the inputs of a Midiman MidiSport2 to one output, and then I feed that output to the Capy. I also have the Capy out going to the MM. The I can play a keyboard and use the MM no problem. This could also be done in Logic. I could also do hannel filtering in the MAX patch, but haven't bothered.
