Hey guys,

 

I'm going to start using hardware synth with Renoise and I am setting up my routing so I can record all synths together.

 

I own an RME Babyface and will add an ADA8200 in order to get 10 analog input (2 Analog + 8 ADAT). I would like to record each synth to it's own track (3 Stereo input and 4 mono input).

 

The "#Line input" device sees my RME Babyface input but only allows me to select 2 channels together.

So I can only select two channels at the time instead of, for example getting only Adat 7. Is this normal?

 

On Cubase, I can see all my channels and they are not paired in stereo.

I have tried changing all the setting I could in totalMix (RME routing software) but nothing changes in the Line-In tool, I cannot select a single channel.

 

Does anyone know if this is normal? Or am I doing something wrong?

 

Thanks a lot

 

Thomas

Renoise works stereo only. You need to work around it, but this is possible.

 

For stereo inputs, choose a pair that renoise can select as such.

 

For mono inputs, just use a single input on the sound card. Then, with the line in device, select the pair that has the channel of choice as either left or right channel. Put a stereo expander after the line in device. Set "Expand" all the way to the left so it reads "Mono". Then as "Mono Mix" option choose the channel that has the signal you want, either "L" (left) or "R" (right). Tadaa, you converted your mono input to stereo in renoise.

 

For outputting to a mono line you would need to use a send channel to output stereo on the 2 channels of choice, and hard-pan with send devices sending to there - left and right your mono signals.

I love the Stereo Expander device! It's a perfect solution to the OPs issue, and FWIW applies elsewhere as well -- meaning, whenever you want to take just one half of a stereo signal and thereby have a true mono channel, you can use the Stereo Expander as explained above (slider to "mono" and choose L or R, depending which you want) and then bam, you have a true mono signal in your channel. I find this is often more useful than "summing to mono" (done by dragging slider to Mono but *not* choosing L or R) becuase summing often results in a weird phase-y or muddy sound from the material in both channels being copied to the other.
