MIDI expression i/o compatibility with usb controller

[theredbull]

Hi.

Great product and website.

I have a USB midi controller that connects to my laptop (Windows, running reaper). It is a six channel monophonic controller, each channel carrying different "parts" at any one time (channel 1-6).

I am wondering if I can use the "MIDI expression I/O" to connect two sustain pedals and one expression pedal to my DAW in order to control the routing of the six different midi channels to a vst.

Specifically, I would like to use the pedal(s) to select which of the controller channels (1-6) plays through a VST at any one time. i.e in a "live" situation.


This looks possible from the "Global channel tutorial" but in my case there are two distinct differences in the set up:

1) My midi controller is USB into the DAW (you are using a 5 pin input from a controller keyboard into the DAW)

also

2) I require to send the MIDI data from the USB controller (all six channels) to another midi hardware device (drum synth) at the same time via my DAW midi out port.

Would "Midi Expression i/o" allow MIDI thru or would I even need to use the MIDI ports at all on the "MIDI expression I/O" for the above scenario?

Thanks for any information.

Any chance you'll tell me the name of this controller?

The Global Channel feature changes all MIDI messages to use the same channel, but it sounds like you are actually looking for a way to only pass MIDI messages that are on a specific channel, so I'm not sure if the Global Channel will give you what you are after.

My midi controller is USB into the DAW (you are using a 5 pin input from a controller keyboard into the DAW)

All my devices support the Global Channel feature. On the original MIDI Expression and the Quattro, there is a 'MIDI Loopback' switch. The idea is that you can route any MIDI to the device, process the data with the Global Channel, and then 'loop' it back out the USB MIDI connection. So in Reaper, you could send the MIDI from your controller to a MIDI Expression as well as your hardware drum synth. And then on a separate track, you would send the MIDI data coming from the Expression to your VSTi. In this sort of setup there is going to be some latency, however.

The MIDI Expression iO is still in it's infancy. The processor in there is quite powerful and there's room for a lot of development. I have a very rough plan to support a whole filter section similar to Cubase's 'Transformer plugin, but it's still a long ways away.
