Hello, I have 3 other devices (Novation Bass Station II, Yamaha PSR E-443 and Yamaha DJX-II) which I would like to connect to my Motif XF’s A/D input.
Normally I wanted to buy a real audio interface, but due to different reasons,
I was thinking about some kind of audio splitter where I can connect my 3 other keyboards/synths.
Sure it’s not professional, but it might be enough for an “advanced beginner” like me.
All other devices are/will be connected to the PC via USB as well.
So in theory it should be possible that the XF controls the other 3 devices
What do you say?
Thanks for any help! Image Attachments

A splitter is, not surprisingly, meant to accept a single input and split it into two or more outputs. While in some cases a splitter can be used in reverse as a combiner, there are usually several reasons not to do that. What you want is a mixer. Yamaha and other companies make some reasonably priced ones that should do the job. Be aware that the XF’s A/D Inputs are unbalanced, and require the connections to be made with TS plugs. For your purposes, you might consider a passive (unpowered) line mixer. |

ART makes an inexpensive passive mixer with four stereo inputs. About $50 online. |

Hello and thank you for your replies!
I already ordered this audio mixer: Rolls MX 41b, a 4 channel stereo mixer.
Some guys write that they opened its case and removed the 8 resistors
Regarding the current cable which is plugged in the XF’s A/D input:
I noticed that when I haven’t plugged my cable in the A/D input,

The purpose of the resistors in a passive mixer is to isolate the inputs from each other, and it protects the output stages of each source (the synths being connected). Removing the resistors defeats that - it would effectively make the mixer, when its level controls are turned fully up, like a splitter used in reverse. If the level isn’t sufficient with the mixer’s input controls turned all the way up, the output levels maximized on the synths, and the XF’s A/D Input Gain control at maximum, then the XF’s Utility mode mic/line setting can be changed from “line” to “mic”. If you do that, start with all the controls turned down and bring them up only as needed..

The “mono” 6.3 mm (1/4") plugs are TS type, which is correct. |

Hello,
I made the first tests.
When two devices are connected to the 4 channel mixer,
But what still bothers me a bit are the idle frequencies coming from the A/D.
I just want to avoid that when I make a complete song louder,
An alternative solution (no idea if this is handable):
