Hello everyone,

I am wondering if anyone knows of any hardware (preferably small) that will take incoming polyphonic midi note data from a midi controller and will separate it into three channels. The first channel would be a straight passthrough of the polyphonic note data, the other two channels output would be monophonic, one being the lowest note played, and the other being the highest note played. Basically one would behave like a monosynth that is low note priority, and the other being high note priority. I would like to be able to control 3 voices (two mono, and one poly) from a single keyboard without having to rely on keyboard splits. I have an Elka OMB-5 that has a separate bass voice that is low note priority and it makes for some really interesting playing possibilities but I would like to be able to do this with different instruments (such as a yamaha TX802, which is multi-timberal) and with the addition of a higher voice. I could probably figure out how to implement this using something like max/msp, but I don't want to have to deal with a laptop in my live setup.

Thanks for any info!
-Matt

Did you find anything?

Sorry for this late reply but I've had such a device in my arsenal for years, I've used it both live and in the studio.

It was custom built for me, but I've recently re-written the software for Arduino and have been contemplating releasing a commercial version this year. I did also look into the MIDI Solutions box to do this, but I couldn't get a satisfactory result with it.

There are, by the way, several enhancements that can be added to the simple 'lowest note' algorithm that make it much more playable, but I'll wait to hear if you're still on the look out before filling in the details.

The BomeBox will do that, too, in conjunction with a MIDI Translator Pro script...

Hi,
Sorry if I misunderstand, but would I be able to use this to split out my incoming midi from an ekit? I mean, take midi note 36.. Send to buss 2 channel 2?

That's an interesting use case! We will add a note to include such a capability to our new device called Midihub!

Btw, we're looking for beta testers now!
