Hi,
I’m trying to configure little setup with Zynthian, old Yamaha QY70 sequencer and midi keyboards.
I’v got midi keyboard with midi in and midi out sockets (no midi thru). It is connected to yamaha midi in and yamaha midi out is connected to Zynthians midi in to play sounds.
I’m building an arduino controler (with simple midi out) to send sysex to yamaha (to muting and unmuting sequencers patern parts). It is running fine and everything is working as I’v planed. But I cannot connect both - my controler and my keyboard to sequencer.
Is there any simple way to connect two midi devices to one sequencer in this situation (a daisy chain or any midi throu cable modification - I do not know)? Please, if someone know the way I will by greatfull. 
Regards,
Adam
