Using Track to Sequence/Filter External Gear

Noob Question.

I know there’s a way to sequence external gear, but run the audio input to one of the 4 tracks, so that you can still use the A4’s filter on the input. (Dataline does this in a couple of his videos, i know the MS-20 Mini video for sure. And i know i’ve seen it mentioned in other posts here, i just can’t recall which).

Can someone talk me through how to do this? I thought it would be as straightforward as setting the wave type for the oscillator on a given track to Input R/L, but this doesn’t actually seem do do anything. Is there a menu i need to explore further?

Thanks for the help.

Just put a trig into the sequencer and choose long envelopes so that you can hear a sound. External audio is treated like an oscillator.

this is something I really cant get my head around! … on occasions it seems to work, on other occasions I really dont know what I do and i cannot tell if anything happens at all … so if you get lucky with your experiments drop a tutorial , (for me) :slight_smile:
good luck !

Also a combination of TRIG LENGTH and ENVELOPE would lead to nice and more complex situations!

Envelope, of course, reacts to the length of the trig
