Xpantastic!

You cannot detune the 6 voices of a Xpander separately, even not in "unison mode".
You don´t even can detune a patch, you loaded in each slot of a multipatch in a Xpander and like you can w/ a Matrix-12.
There´s no detune page in the Xpander.
As a workaround, you can store the same patch to 6 single patch memory locations, each version of this patch slightly detuned already,- then load in a multipatch and adjust volume and pan there and play all unison.
But this wastes 6 memory locations for each unison-detune sound.

That´s the benefit of a Matrix-12,- 6 more voices, the detune page and the modulation page for better visability of used modulation sources and destinations,- that´s all.

Matrix-1000 has a unison mode already and is cheap,- stack 4 and detune ´em globally against each other while each being in unison mode.

I don´t know if the Matrix-1000 has enough processing power for your planned hack.
It has the same processor than Matrix-12 and Xpander,- but the Xpander has 2 already.

In the Matrix-12, there are simply 2 voiceboards you stack.

You can put Matrix-1000 and Xpander in "guitar" mode,- so each voice receives pitch bend data separately on different MIDI channels.
With a sequencer, you can detune the voices that way, or if you own a MIDI processor w/ the ability storing and transmitting MIDI CC offset data to different MIDI channels, you can do it that way in realtime.
If the sequencer or MIDI processor is able to store sysex commands in addition and transmitting these, in strictly sequencial order and together w/ MIDI program change commands as well as MIDI CC offsets, to the Matrix-1000, you´d be able to remotely switch between operation modes like normal operation, unison mode and "guitar" mode.

Look at the MIDI specs in the manual.

Hi,

I thought if you could modify the M1000 ROM chip (with the OS on it),
you could make it detune across all 6 voices, play in unison!

This would be an amazing way to get a phatter sound from this synth, and
approach Xpander levels of sound.

Any thoughts?

Jeremy.

PeWe

I don't understand exactly what you're referring to.
If each single patch in a Multi patch is manually detuned - by going into the Osc Page and changing the Freq (??) value to - (insert random value), why won't that "detune each voice independently" ?
