output routing
« on: July 07, 2019, 09:16:32 PM »
How can one  instrument play only at one mono output,
or how it can programmed to play all 4 instruments to 4 outputs individually?
I'm sure it works, but can't find it in Menu.
Thanks

Hi,

I am pretty new to the Preen, and I have the exact same question.
From what I can see on the schematics, the two DAC outputs on the MPC4922‘s, are summed to one op-amp each, so there would at least 2 more op-amps be needed.
I don‘t know if SPI_DAC1 and 2 can send stereo-Data, or if two more SPI_DAC‘s are needed.

Can anyone enlighten us?

Best,
Omnichordman

...I just saw, that the two 12-bit channels of the MPC4922 are combined for the 18 bit resolution of the output. So my educated guess is: the PreenFM2 is two channel audio out by design.
So I think it would be easier and even cheaper to put two Preens in one housing, for 4-channel FM.

Best,

Correct.

But you can redirect one instrumnent to one mono channel and a second one to the other.
Go to the mix engine menu, then turn right or left one of your op while holding down the mid left button. That will turn all mix* at the same time.
