hi list,

let's say you have two Xpanders midied together (midi out from one to midi in of the second).
does the Xpander support a 'midi overflow' mode, so you could play two Xpanders as one 12-voice machine?

NO !!!


thanks in advance for your help!

There\ufffds no help possible except a firmware/OS hack or a ext. hardware device which doesn\ufffdt exist AFAIK.

The Xpander MIDI Out set to "MIDI ECHO" just echoes what comes in at it\ufffds MIDI Input.

A 2nd Xpander receiving MIDI info from the 1st Xpander\ufffds MIDI Out (in MIDI Echo Mode) receives the SAME notes, controller data and sysex.
That way, it will be 2 MIDI layered 6-voice Xpanders in general,- not discussing the common zoning features and combinations w/ 2 XPanders linked via MIDI here.

To make 2 6-voice Xpanders a 12-voice Xpander, in theory there would be 2 ways:

MIDI spill-over or recognition and MIDI filtering of odd and even MIDI note numbers.
Some 19" MIDI tone generators use the MIDI note numbers.

Recognition of odd and even MIDI note numbers would work on the same MIDI channel in single-path mode and on the same MIDI channels in multi-patch mode, the zones set up exactly the same.
That would be a functionality, we\ufffdd wish to have in the Xpander itself.

To be precise, Xpander #1 plays the even MIDI note numbers and Xpander #2 the odd MIDI note numbers.

IMO, it would be the more interesting method w/ 2 Xpanders because we also deal w/ the voice panning here which is not w/ a Matrix-1000.

If deviding odd and even MIDI note numbers would be a task for a masterkeyboard, the masterkeyboards features would be different,- p.ex. transmission of odd MIDI note numbers on MIDI channel X and even MIDI note numbers on MIDI channel Y (1 MIDI Out port),- and Xpander #1 set to MIDI Ch. X while Xpander #2 being set to MIDI channel Y, - the Xpanders daisy chained via MIDI Out Echo > MIDI In.

Or,- transmission of odd and even MIDI note numbers on 2 MIDI Out ports of the masterkeyboard (if it has 2 MIDI Out ports) but same MIDI channel,- each Xpander connected to one of these ports.

Or split of MIDI note numbers across 2 MIDI channels and 2 MIDI ports.

All is thinkable and would work.

Unfortunately, there\ufffds no masterkeyboard out there I know, splitting odd and even MIDI note numbers and transmitting these on different MIDI channels or different MIDI ports.
I hoped a Oberheim XK can but it doesn\ufffdt and none of my other keyboards does.
Also my MIDITEMP PMM88E can\ufffdt.

If anyone knows a hardware MIDI processor doing that,- let me know ...

I\ufffdd call it "Odd-Even MIDI Note Splitter" (MIDI Ch. or MIDI Port Split)

If someone has the skills and thinks about building such little box,- splitting note numbers into MIDI channels on 1 MIDI port would be the most compact and cost effective solution.

I wonder why it doesn\ufffdt exist made by Midisolutions,- they have the skills to realize that w/ ease.
Possibly it could be realized w/ this box,- just the processing function is missing:

They do modifications of their products on demand as also customized products.

If that is done,- you need a keyboard providing power over MIDI to their boxes,- in the FAQ is a long list which products don\ufffdt and I doubt it\ufffds complete.
