SpiceCore

SpiceCore is a generative synthesizer for iPad.

A polyphonic analogue-style engine — dual morphing oscillators, a dual filter with four modes and parallel routing, OSC-FM and ring modulation — with the warmth, drift, and character of the real thing.

What makes SpiceCore different is its generative engine, with three ways to play: a 32-step sequencer with Euclidean rhythms, Markov evolution, and bounded mutation; a Motion Arp; and Harmonic Mode. Four macros — Mutation, Density, Chaos, Memory — put generative behaviour at your fingertips, with their own values per generator.

MIXER & EFFECTS
Every part gets its own channel: a level knob for the sequencer, arp, Harmonic, and your keys, with a delay send and a reverb send beneath each — feeding a tempo-synced delay and a plate-style reverb. DLY Age turns the echo towards worn tape; RVB Grain gives the plate its metal and shimmer. At zero, both are exactly clean.

THE CONDUCTOR
Switch it on and the performance breathes — macros lean, parts swell and recede, the space opens and closes over minutes. It wanders from the pattern seed, so the same performance returns every time.

SOUND PALETTE
Load up to four sounds and one pattern plays them all. The instrument spreads the notes across the palette along a tempo-synced morph — stepped to a pure sound per note, blended between sounds, or stacked — while the ribbon shows you what is playing.

HARMONIC MODE
Turn the keyboard into a chord surface. One key picks a chord and SpiceCore voices it for you, with three layouts, six chord colours, four voicing styles, and a motion engine for strum, pulse, arp, and evolving figures. It plays over the sequencer or arp — and the chord you hold leads them, so the pattern follows your hands.

SOUND LAYERS AND SOURCE MIX
Each generator can carry its own sound and its own level. Give the sequencer, arp, or Harmonic part a voice of its own while the pattern stays shared, then balance each part against the others.
