[ACCOLADES] - Featured in Apple's staff favorites! - Reviewed in Computer Music magazine and received a 9/10! [DESCRIPTION] Jasuto is the worlds first (and most powerful) modular synthesizer for the iDevices. Jasuto allows you to visually construct your own synths/effects, and use them to make sequences all on your device! With the addition of a fully-featured sampler you can now record/resample/edit, and even create entirely new samples by drawing right in the app. Jasuto uses the relative position of nodes and their connections to control the sound. So the scene not only represents the synthesis structure, but also a custom multi-touch control surface. Motion can be recorded per node giving you rich, flexible automation. Connections can be created automatically by simply dragging nodes around, or manually. Each wire can be double-tapped to allow even more control of each connection. Jasuto comes installed with 75+ modules as well as 200+ pre-loaded scenes and samples. Each of the modules have been hand-optimized for your device's CPU, allowing you to create extremely complex scenes. [NOTABLE FEATURES] - Anti-aliased oscillators with hard-sync, FM, PWM, PM - Analog style filters (ap, lp, hp, bp, ladder emulation) - Signal control (compressor, limiter, gate, follower) - Zoomable sampler editor with several loop modes (normal, 1 shot, ping, granular) - ADSR envelope editor - Multipage/octave sequencer - Tape style analog delay - Reverb, phaser, several waveshapers - Resample/record the current playback - Audio copy via the pasteboard - Incoming OSC and MIDI for notes and CC's - Audiobus support (input, effect & output source) - Completely compatible with iOS7 - Updated UI graphics - Universal device and Retina support - A shiny new manual - Added background audio support - Low latency audio (256 samples) - Sample sharing through SoundCloud - Dropbox syncing of samples/scenes - High Fidelity (Hi-Fi) Audio [WEBSITE] http://www.jasuto.com

Introducing the queuing synthesizer for iPad. SynthQ has been designed from the ground up with the touchscreen interface in mind. SynthQ is a subtractive synthesizer with a customizable interface. A unique module queuing system, resizable multi-octave keyboard, and intuitive cable-based modulation controls offer a truly dynamic music-making experience for iOS. Each part of the synth is separated into units called modules. Each module snaps into place along a scrollable surface above the keyboard. Control the number of modules shown on the screen at any time. Control which modules appear for each sound. Tap a button on the module menu to launch a module and add it to the queue. Drag a module up and release to remove it from the queue. Drag a module down to move it within the queue. Add variability to your sound by connecting different modules using virtual cables. Alter the sound with synthQ's movable keys. SynthQ provides an intuitive and engaging way to get started creating your own sounds, and is ideal for production, performance and music education environments. Full feature list: MODULES: —three oscillators — sine, triangle, saw, square, pulse and resonant noise waves —three adsrs — amp, filter and modulation envelopes —filter with lowpass, hipass, bandpass, band-reject and peak filter modes —glide —frequency modulation oscillator —ring modulation oscillator —eight modulation bays with virtual cables enable interactions between modules —three tempo-syncable LFOs with sine, triangle, saw, reverse saw, square, random curve and random step waves —two XY matrix pads —XY keys module turns the keyboard's movable keys into modulation sources —sequencer module with Ableton Link support and built-in arpeggiator mode —vocoder using microphone or Inter-App Audio Effect input —two FX slots with chorus, flanger, phaser, reverb, tremolo, distortion, delay and bitcrush —analog simulation with soft clipping and random pitch wavering —midi module with pitch bender, modwheel and velocity —master volume control INTERFACE: —multi-octave resizable keyboard with 10-voice polyphonic, monophonic and legato modes —optional "sticky keys" mode locks each key to your finger after being pressed —when used as a modulation source, sound can be altered by moving the keys in different directions —unique rearrangeable module queuing area defines which controls are present per preset —fully featured preset menu system with options to share and import via e-mail or iTunes File Sharing —import presets directly from iOS mail by tapping and holding the attachment and pressing "Open in synthQ" —functional graphic design and layout eliminates screen switching by keeping the control modules and keyboard in constant view OTHER FEATURES: —Audiobus 3 support with Inter-App Audio —A=432Hz, A=440Hz and A=444Hz tuning modes —44100k Hz, 32000 Hz and 22050 Hz sampling rate modes —MIDI input and output per channel —basic recording feature to save, play, loop, and share recordings —import .WAV files from iTunes File Sharing for playback —parallax motion effects Follow @synthQ on Twitter for latest announcements and free preset packs, updated regularly!
