K-One is a classic, warm analog synth AUv3 app for iOS made in Audiokit.

Features:

Over 75 bespoke presets, made in consultation with some of the top music producers in the UK.
30 parameters for complete creative control. All mappable when used as an Auv3 audio unit.
K-One is based around four oscillators – a pulse wave, morphing sine-sawtooth wave, square sub and a noise oscillator.
A smooth, Moog-style resonant low pass filter, which can be modulated with its own envelope as well as via LFO.
5 different effects, including overdrive, delay, reverb and two custom made choruses, which give a deep, richness to the sound.
A non-resonant highpass filter.
Two ADSR envelopes for modulating the amp and filter.
Capable of an uncapped amount of polyphonic voices, or switch to the fat mono mode for basses and leads.
Pitch bend control.
A 127 note on-screen keyboard.
Compatible with Audiobus, Inter-App Audio, AUv3 and external midi control.
