Switched-On Scarlatti On Casio CZ-101


Synthesist Dylan Pank shared this ‘switched on’ style Casio CZ-101 arrangement of Scarlatti’s Sonata in D minor K.1.

The arrangement highlights the multi-timbral capabilities of the CZ-101 – which are more capable on this synth from 1985 than most modern synths.

Technical details:

“Scarlatti Sonata in D minor K.1, arranged for 4 parts, controlled via midi from Musescore 3, recorded direct into Audacity, reverb and stereo conversion added in Audacity.”

Erica Synths Announces Graphic Resonant Filterbank + Expander Modules


Erica Synths has announced two new modules, the Graphic Resonant Filterbank and a companion module, the Graphic Resonant Filterbank Expander:

  • The Graphic Resonant Filterbank (FB) is a ten-band analog filter bank, with digital control over each bands’ boost or cut. Each band can be controlled individually via CV or manually, while complex control configurations turn the filter bank into an unconventional multimode filter and even an instrument in its own right, when played with various resonance settings.
  • The Expander module (works exclusively with the Graphic Resonant Filterbank and is available separately) provides hands-on adjustment of boost and cut for all bands.


Graphic Resonant Filterbank Features:

  • Analog 10 band filterbank
  • Saveable presets for filterbank, filter modes, dynamic EQ, and resonance settings
  • Main, even and odd outputs
  • Manual and voltage-controlled band boost/cut
  • Configurable resonance feedback loops
  • Manual and voltage-controlled resonance
  • Clock input for synchronization of events with a master clock source
  • Multimode filter mode
  • Spectral analyzer mode
  • Dynamic spectral compressor mode
  • Discrete and morphing pattern change
  • Configurable CV inputs
  • Expander module for immediate access to band levels
  • Skiff-friendly design


The Erica Synths Graphic Resonant Filterbank and Expander Modules are expected to be available Sept 9th, 2024, with the following pricing:

AM1013 Octave Fixed Filter Bank Recreates ‘Lost’ ARP 2500 Module


AMSynths shared this demo of the AM1013 Fixed Filter Bank – another in their series of 10 ‘lost’ ARP 2500 modules.

The AMSynths modules complement Behringer’s line of ARP 2500 Eurorack copies, and are inspired by ‘lost’ ARP 2500 designs from 1970.

The AM1013 Fixed Filter Bank features eight 12dB fixed band pass filters in parallel, each with “a nice gentle resonance”. It offers individual outputs, mix outputs and a bypass feature.

See the AMSynths website for details.
