RAVEN – Wavetable Morphing Synth

Dual-oscillator drawable synth – A deep, drawable synth built for evolving textures and sculpted sound. Now available — launch price for a limited time.

RAVEN is a deep, expressive wavetable-morphing synthesizer designed for evolving textures and sculpted sound on iOS.

Built for musicians, producers, and sound designers, Raven delivers drawable waveforms, real-time morphing, and a full effects chain in a clean, performance-ready interface — whether you’re crafting pads, designing sounds, or playing live.

Key Features:

  • Dual drawable oscillators with wavetable morphing
  • Utility oscillator (sub, ring mod, FM, noise, harmonics)
  • Classic ladder filter with 12/24dB slope
  • Dual ADSR envelopes (Filter + Amp)
  • LFO for pitch, filter, PWM, morph, and amplitude
  • 12-band parametric EQ
  • Delay, reverb, chorus, and distortion FX
  • 56 factory presets with QR code sharing
  • Touch-optimized performance controls
  • AUv3 instrument support
  • CoreMIDI & Bluetooth MIDI
  • Designed for iPhone and iPad

An iPad synth like Raven sits in a pretty unique sweet spot between desktop power and hands-on playability. The touchscreen changes how you interact with synthesis in a big way:

  • Drawable waveforms → way more intuitive with your finger than a mouse
  • Real-time morphing → you can literally “play” timbre by dragging
  • Performance controls → gestures = expression (kind of like an instrument, not just software)

It puts it closer to apps like Moog Model D, KORG Gadget, or Animoog Z—but Raven leans more into custom waveform design, which is more like desktop wavetable synths (think Serum/Vital style, but touch-first).

Where iPad synths shine:

  • Sketching ideas quickly without a full DAW
  • Sound design that feels tactile
  • Playing live with MIDI controllers or just the screen
  • AUv3 support → you can load it inside apps like AUM or GarageBand

Raven specifically looks like it’s aiming for that “Serum-style sound design but playable like an instrument” niche on iOS.

ButterSynth iPad Synth

ButterSynth is a hybrid 6-oscillator synthesizer with a vast sonic range, from gentle pads to screaming leads and basslines. It’s like Serum for the iPad and iPhone.

ButterSynth is a hybrid 6-oscillator wavetable/FM/sample-based AUV3 and standalone synthesizer with a vast sonic range, from gentle pads to screaming leads and basslines.

Mix any combination of wavetable, FM, sample and other synthesis engines for one truly massive sound.

For the more advanced users, you’ll love using ButterSynth’s thoughtfully designed interface, incredibly powerful modulation matrix, fully-featured internal FX rack, factory waveform and sample libraries, and almost limitless scope for fun, experimentation and sound design.

For less experienced synth programmers, ButterSynth includes a library of hundreds of ready-to-use presets, sparking your creativity to start making music right away.

Headline features include

– Mix and match any combination of 6 synthesis engines to either emulate your favourite synths of yester-year or build a synth ready for the future.

– Dual-wavetable engines also feature 9 phase modes, wave folding, and deep unison controls modelled on vintage hardware synths.

– Built-in wavetable editor gives you the ability to tweak, morph, and hand-draw your own custom wavetables, with each wavetable supporting up to 256 frames.

– FM engine offers 4 operators with a selection of 12 modulation paths. Each operator can be loaded with any waveform from the factory or user library, and can also self-modulate via the feedback dial.

– Sample and Granulator engines both let you load samples (either imported or from the factory library) and control precisely how they are chopped, triggered and layered. Both also feature the same powerful unison modes available in the WT engine.

– Highly configurable 32-slot modulation matrix featuring precise mix/max ranges, self-modulation (via the amount target), plus configurable response curves and layer modes. Simply long-tap any parameter to set it as a Mod destination!

– Full suite of versatile control sources which includes: 4x MSEG-style looping curve envelopes, 4x LFOs, 4x step sequencers, X/Y pad with motion recording, 8x Macro dials and a powerful arpeggiator inspired by Kirnu Interactive’s Cream.

– The EFX rack lets you build your own insert effects chain using any combination of the 16 built-in FX modules. Modules available at launch include delay, reverb, distortion, chorus, OTT compression etc. Note – FX parameters can also be targeted by the mod matrix, unlocking the possibility to program ‘per voice’ modulated effects.

– All presets, wavetables, samples and other settings are stored in the Files app, making bulk import/export, backup and community sharing quick and easy.

– All of this is housed in an irresistibly designed 4-tab UI that makes synth programming quick and fun.
