Connecting balanced S-out gear to balanced M-in gear (via patchbay) Virtual Instrument Plugins

Connecting balanced S-out gear to balanced M-in gear (via patchbay)

Hi, I wonder if anyone can help. Currently I have keyboards and synths etc running into a 1/4" patchbay, and also the Akai MPC which I record into.

Recently, the left balanced jack input on the MPC has gone dodgy. I'm planning on looking ito that - but in the meanwhile, I've realised I'm happier to record keyboards in mono anyway... I can just select "mono(right)" on the MPC when im recording.

I dont want to have to rewire the entire patchbay in mono. So I'm wondering how I would go about patching the left and right balanced outputs of the keyboards, to the balanced mono input on the MPC (via patchbay, or not).

I've seen Y cables that are 2 mono jacks>stereo jack. That might work in the patchbay to some extent, but it would lose the balanced connection. I want to take the seperate balanced left and right outputs of a keyboard, and have it go to a balanced mono input. I'm guessing a lead can't do that 'conversion'.

Thinking about it, this also goes for putting other instruments and mic preamps through the patchbay too?

I hope someone knows what I'm getting at, if so, can you clear this up for me? (heads gone in circles trying to figure it out).

Ideally you'd want the output signal of the keyboard to be buffered for the optimal impedance match/lowest noise. That would require dropping a mixer with balanced ins between the keyboard the the MPC. The y cable would work, might introduce a little noise.
