About

Virtual ANS 3

This app simulates a unique photoelectronic musical instrument, allowing users to draw music as spectrograms. It functions as a graphics editor to convert sound to images and vice versa, enabling the creation of atmospheric sounds and microtonal music.

Highlights
  • Unlimited pure tone generators
  • Sonogram editor for drawing and playing spectra
  • Convert sound to image and vice versa
  • MIDI device support
  • Polyphonic synth mode with MIDI mapping
  • Audio Unit Extension (AUv3) and Audiobus support

Read full description

Virtual ANS is a software simulator of the unique Russian synthesizer ANS - photoelectronic musical instrument created by Evgeny Murzin from 1938 to 1958. The ANS made it possible to draw music in the form of a spectrogram (sonogram), without live instruments and performers. It was used by Stanislav Kreichi, Alfred Schnittke, Edward Artemiev and other Soviet composers in their experimental works. You can also hear the sound of the ANS in Andrei Tarkovsky's movies Solaris, The Mirror, Stalker. The simulator extends the capabilities of the original instrument. Now it's a full-featured graphics editor where you can convert sound into an image, load and play pictures, draw microtonal/spectral music and create some unusual deep atmospheric sounds. This app is for everyone who loves experiments and is looking for something new. Key features: * unlimited number of pure tone generators; * powerful sonogram editor - you can draw the spectrum and play it at the same time; * any sound (from a WAV file or a Microphone/Line-in) can be converted to image (sonogram) and vice versa; * support for MIDI devices; * polyphonic synth mode with MIDI mapping; * supported file formats: WAV (only uncompressed PCM), PNG, JPEG, GIF; * Audio Unit Extension (AUv3), Audiobus; * many new features compared to version 2.3; see the full list: https://warmplace.ru/soft/ans/changelog.txt Homepage, user manual and versions for other systems: https://warmplace.ru/soft/ans

Tera Pro brings together all major sound synthesis methods on one table. No matter if you want to recreate sounds from analogue legends or explore modern digital sounds with FM, Waveshaping or Wavetable synthesis. More can be added by In-App Purchases of new modules. Add some flavour of physical modelling and modules for additive synthesis. Combine them altogether for new sound experiences far beyond your wildest dreams. Tame this overwhelming amount of possibilities with Tera Pros intelligent user interface showing you only exactly what you need, paired with realtime oscilloscopes and level indicators helping you seeing what’s going on. Connect the modules with a flexible routing method without the visual cluttering of real wire cables needed in conventional modular synthesisers FAQ What does Tera Pro have that Tera Synth doesn't have ? 1) Additional Sound Modules - Spectrum oscillator ( borrowed from the heart of Addictive Synth ) - Wave shaper / folder opens the west coast synthesis - Vocal Morphing filter - KARPLUS (aka WaveGuide ) with new "Swarm" mode ( 3 detuned delays ) 2) Revised engine - Analog Polysynth Voice Modelling with characteristic subtle voice variations of timbre, pitch and temporal behaviour to get you "The" Analog Sound. - 128 vs 32 voices polyphony - Seamless Sound Switching: change presets during play without cutting off the sound. - 8 times unison for really heavy ambients - Envelope generators with Buchla style "end of cycle" trigger for generative music - Stack/Split Sounds - New effect section 3) Redesigned User Interface - Collapsible modules for clear view of modular structure - No more nasty popups for LFOs/Envelope generators - Realtime oscilloscopes added to selected modules 4) New Presets - About 1000 additional presets in there.

Verdict

The call

The clearest difference is in-app purchases: Virtual ANS 3 at none against Tera Pro's 6. Virtual ANS 3 also leads on review sentiment (88% vs 69%) and rating (4.8 vs 4.6). Tera Pro's advantage is update cadence (every 5 days vs every 3 months). On ratings volume, ads, device support and iOS requirement there is nothing between them.
