Eurorack Modular Workshop: String Filter experiments

In this eurorack modular workshop video I explain the usage of the EFFEXX string filter algorithm. If you already have an EFFEXX module you probably also have the three additional modules I used for this workshop. For my sound examples I added one Noise generator, one ADSR envelope generator and one VCA. The workshop explains the cabling and gives a lot of tips how to tweak the parameters for different sonic results.

If you just would like listening to the string filter sounds, you can skip the first 4 minutes of the video.

RT-1701 Multi-FX EFFEXX demonstration

I created a little video demonstrating the tempo delay, flanger, reverb and lowpass filter of the RT-1701 EFFEXX module. At the last third I create some snapshots and crossfade/interpolate through them. The drum groove comes from the Spectralis 2. I created the drumsounds with my eurorack system and imported the samples into the Spectralis 2 sample engine. The kick drum doesn’t run through the EFFEXX in this example.

EFFEXX RT-1701: New Audio Demo Vintage Delay


One of the most popular FX algorithms nowadays is a vintage style tape delay emulation. The modification of the delay time caused a pitch change because you moved the head directly at some devices or/and switched to another motor speed what involved acceleration effects. The EFFEXX sports up to two of these vintage delays simultaneously plus reverb, post EQ and pre overdrive. With other words – you can create really spectacular SFXs with the module. As a sound source I used the RT-311 Swarm Oscillator and the RT-451 Dual Multimode Filter. Furthermore I added three Doepfer modules to this setup – the A-155 Analog Trigger Sequencer, the A-132 Dual VCA and one A-140 envelope generator.
