Sending several parts to one reverb return places them in a single shared acoustic space

Instead of a separate reverb per element, sending multiple parts to one shared reverb return blends them into a common room while leaving their dry transients intact. In the Armando build the drum bus is sent (~-19 dB) to a return running Reverb at 100% wet, ~2.50 s decay, with an EQ on the return cutting lows so kicks don’t echo into rumble; the two 303 basslines are then sent to the same return to place all instruments in a uniform space. Keeping the send well below 0 dB and cutting lows on the return adds ambience without muddying attack or bass. Historically this is why many 1980s electronic productions have wet drums - the shared reverb made drum machines sound more live.

Examples

Create a reverb return (Dry/Wet 100%, decay 2.5 s, EQ low-cut on the return). Send the drum bus at ~-19 dB and send the bass to the same return. Compare a dry kick vs the sent kick: the tail gains room, the attack stays.

Assessment

State why the reverb send is kept near -19 dB and the return low-cut, and explain how a shared send unifies drums and bass better than per-track reverbs.
