Pumping bass sounds on the XW-synths
Very common in electronic dance music is to have a bass sound that “pumps” on the off beat and doesn’t clash with the frequencies of the kick drum. The common way to do this is to “duck” the volume of the bass sound down using a compressor so that when the kick drum hits, the volume of the bass sound is reduced, then the bass sound returns to normal volume as the kick disappears.
The XW’s can recreate that effect a number of ways but I created a sound that utilizes a very powerful feature of the XW’s Solo Synth engine. The envelopes have a “Clock” feature that will cause the envelope to repeat to the tempo and division of the beat that is chosen. In this case it repeats each beat and with a slow attack time you get a nice swell into the off beat.
This sound can be heard in this demo which also uses the PX-5S for some other sounds.
