Arturia’s FX Collection features 15 premium effects created using the same True Analog Emulation physical and circuit modelling employed in their V Collection synths. Processors include channel strips, delays, filters, compressors and reverbs but, until now, no modulation effects. Thankfully their three new plugins resolve that situation. Chorus Dimension D, Phaser Bi-Tron and Flanger BL-20 (VST, VST3, AU, AAX) are circuit-accurate emulations of three modulation classics, and are now available as the 3 Modulation FX You’ll Actually Use bundle (€199) or individually (€100).
The original hardware versions of all three processors have quite interesting design features. The Dimension D is valued for its subtle sound and stereo effect and its black box design has always created a real air of mystery. Under the hood are two BBD (Bucket Brigade Device)-based delay lines modulated by a triangle-shaped LFO. The LFO to one delay is inverted and careful cross mixing of the two signals coupled with pre and post filtering and the stereo in and stereo out signal all contribute to its sound.
