Hilda, New iOS Synth features The Most Interesting Aspects Of ‘West Coast’ And ‘East Coast’ Synthesis

Developer Bram Bos has introduced Hilda Synthesizer for iOS, a synth that inspired by the most interesting aspects of both West Coast and East Coast synthesis.

It features a wave folder, lowpass gate, and audio-rate modulations, but also a 12-mode filter and traditional VCA circuit.

Bos says that all parts of the instrument are carefully circuit-modeled to sound as analog (or digital, where applicable) as possible.

Video intro, via Gavinski’s Tutorials:


  • Full Audio Unit compatibility (AUv3 instrument, audio effect and MIDI processor modes supported)
  • Universal design (iPhone and iPad; iPad Air 2 or higher recommended)
  • Built-in analog style 16 Step MIDI Sequencer with custom scale
  • 12 mode filter, based on the Oberheim Xpander design
  • Drone mode lets you [partially] bypass the VCA/LPG and just go with the flow
  • DIY Lo-Fi delay circuit emulation
  • Live pads with effects that can be triggered via the UI (or via exposed AU Parameters)
  • All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice)
  • MIDI Processor plugin mode disables synth to save CPU

Hilda Synthesizer is available now for $12.99.
