Precision Analogue Filter vs. Valve Timbre Sculpting // Swell from Bartola Instruments

video upload by DivKid and Bartola Instruments

"Here we have Swell the new filter and valve (tube for those in the US) sculpting Eurorack module from Bartola Instruments. This is the first commercially released Eurorack module from Bartola and follows many years of valve hi fi work and hundreds of Eurorack prototypes made in super small runs for musicians and friends. Swell offers masses of customisable sound sculpting marrying its precision low pass filtering with high flexible valve control. Whether it's cleaner, yet warm and gently compressed waves or all out untamed chaos there's a lot to explore as you'll see in the patches."

Patching Exciting Modulation for Filters // FIRST PATCH with Swell from Bartola Instruments

video upload by DivKid

"Here we have the new Swell Eurorack filter and valve gain stage from Bartola Instruments. We'll be exploring this in the usual in depth DivKid demo style in the future but wanted to share our literal first patch playing around with saturating, character oozing valve distortion and filtering ... and in doing so, share some modulation tips about how we like to patch modulation, mixing sources and making things feel exciting and dynamic. I hope the patch notes below are useful and let us know what you'd like to see more of with Swell."

"*PATCH NOTES*

The simple bit first - AUDIO PATH - two saw wave oscillators, changing the octaves between them at points, mixed into 'Swell' and then output into some stereo FX for background ambience.

The modulation is where this gets exciting going into the FM input (which modules filter cut off frequency) is my main envelope, a simple decay envelope. Resonance is modulated by a step sequence (external attenuation is the key here). Then the v/oct input is used as a place to input a mix of modulation. The first is an accent envelope, patching a less dense gate rhythm into a second envelope and patching that into a mixer. Then outputting the mixer into the v/oct input of the filter. The second is then the same step sequence as the resonance.

So with the mixer into the v/oct and the FM input I have 3 modulation sources modulating the filter frequency - main envelope, accent envelope & step sequence.

Modules used - Thonk Synth VCO, Joranalogue Cycle 5, TINRS Next Tuesday, Making Sound Machines Multiplikand, Bartola Instruments Swell, WMD + Infrasonic Audio Cosmis Debris, Vostok Instruments Fuji, Apollo View IOU, Thonk Synth dual VCA.
