Dual oscillator in same chain?

Hi, I have been using the sine oscillator together with a linear VCA and an ADSR, to make a coomon voice chain ( I still don’t have VCO, VCA or ADSR on my system )

Is there a way to create a dual oscillator voice on the same chain ? I just noticed that when I add a second oscillator, the first stops working. Any input appreciated, thank you !

Super easy - just put each oscillator within a channel mixer unit

Ok thanks … I am shocked by the versatility of the ER-301 !
