About

Pipa Vocal Synthesizer

This virtual instrument generates unique vocal sounds by blending wavetable synthesis with granulated sample playback. It allows seamless morphing between vocal characteristics like pitch and formants, offering extensive control for musical composition.

Highlights
  • Wavetable synthesis and granulated sample player
  • Simulates male and female vocal sounds
  • Continuous morphing between pitch, formants, and dynamics
  • Dedicated envelopes and LFOs for various parameters
  • Legato mode with glide time control
  • Voice spatialization and room simulation
  • AUv3 plugin for compatible hosts

This virtual instrument is a crossover between a wavetable synthesizer and a granulating sample player specialized in generating vocal sounds. Pipa simulates the sound of human voices in a new way; instead of using ordinary samples or processing oscillators with formant filters, Pipa uses a large database of wavetables extracted from real vocal samples. The benefit of this technique is that it’s possible to seamlessly morph between those wavetables with proper phase alignment. This technique enables Pipa to continuously make transitions between pitch, formants and dynamics, which is very useful in a musical context. FEATURES * Features both male and female voices * Continuous morphing between formants, dynamics and pitch * Separate envelopes (with linked release time) and LFOs for formant, dynamics, gain and pitch * Plenty of factory presets * Two MIDI Assignable controllers (Ctrl1 and Ctrl2) for controlling formants, dynamics, pitch and gain * Legato mode with control over both pitch glide time and velocity glide time * Voice spatialization * Room simulation (5 different rooms to choose from) * Reverb (6 different algorithms to choose from) Full documentation, audio examples and video demos available at https://klevgrand.se/products/pipa Note that Pipa consumes quite some CPU - a modern iPad is highly recommended. Pipa is also only available as an AUv3 plugin to be used in an AUv3 compatible host application like Garageband, Cubasis, AUM or similar.

Cube Synth Pro brings you the power and complexity of additive synthesis to your iPad studio. This kind of synthesis is well known for its potential capability of creating virtually any sound you can think of. But it’s also well renown for its huge amount of parameters you have to control for reasonable results. Therefore only a few synthesisers exists which uses this mighty synthesis technology. With Cube Synth Pro this prejudice will no longer be true. Specific sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modelled after the inner workings of natural instruments. In addition to emulating natural instruments Cube Synth Pro gives you the ability to mimic the behaviour of the sound characteristic of vintage polyphonic synths by modelling the slight deviation from perfection which are inherent of analog systems. Cube Synth Pro gives you also a new method of getting randomly generated sound patches in a way you never experienced before: roll the dice! Every single try gives you a new unique sound patch, really every try, promised… Synthesis • Over 400 sound presets • Four morphing sound sources • Up to 512 partials per voice • Harmonic/Inharmonic spectra • User programmable noise spectra • Morphing filter banks • Unison mode with up to 8 oscillators per voice • Unique voice detuning scheme to simulate imperfections of poly analog synths. • 3 Envelopes with 64 time/level segments and tempo sync • Multi level random preset generator • 64 time/level segments per envelope Arpeggiator • Uses programmable sequences with up to 32 steps. • Can trigger single notes and chords. • Unique randomizer generates Arpeggios with 100% usability. • 32 Arpeggios included, unlimited useer arpeggios possible. • For each step you can program tie, accent, transposition and note order Effects • Chorus • Phaser • Overdrive • Ensemble • Echo/Delay • Reverb Global • Standalone App • AudioUnit AUv3 • Audiobus 3 compatible (Input slot) with state saving • Support for Ableton Link. • CoreMIDI / Virtual MIDI / Bluetooth MIDI • Audio recorder.

Verdict

The call

The clearest difference is rating: Pipa Vocal Synthesizer at 4.8 against Cube Synth Pro's 4.4. Pipa Vocal Synthesizer also leads on review sentiment (91% vs 80%). Cube Synth Pro's advantage is update cadence (every 2 months vs every 11 months) and price ($9.99 vs $12.99). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
