Description
SpiceCore, formerly SpiceLab, is a generative synthesizer for iPad.
At its core is a polyphonic analog-style synth engine with dual oscillators, a resonant dual filter, two ADSR envelopes, and two LFOs. Exponential envelope curves, filter saturation, and oscillator drift give it vintage warmth and character.
What makes SpiceCore different is its generative engine. A 16-step sequencer with Euclidean rhythm generation, Markov-based melodic evolution, and a bounded mutation engine creates evolving patterns. Four macro controls — Mutation, Density, Chaos, and Memory — put the generative behaviour at your fingertips.
Motion Arp turns held chords into living musical motion. Five traversal modes, two rhythm engines, eight curated motifs, and six performance action pads give you immediate harmonic ideas without step programming. Hold a chord, choose a motion, and play.
A per-destination modulation matrix lets you route any source to any knob or fader — long-press a control to assign LFOs, envelopes, velocity, mod wheel, aftertouch, randomness, or ArpStep and ArpVelocity. Colored arcs animate in real-time showing exactly how each modulator shapes the sound.
SpiceCore works as a standalone app with its own on-screen keyboard, or as an AUv3 instrument plugin inside Logic Pro for iPad and other compatible hosts.
SYNTHESIS
• Dual oscillators (sine, saw, square, triangle) with octave, fine tune, and mix
• Sub oscillator and noise generator
• Dual filter (high-pass + low-pass) with configurable routing order
• Drive / saturation stage
• Filter keyboard tracking
• Two ADSR envelopes (amplitude + filter) with analog-style exponential curves
• Two LFOs (sine, triangle, random)
• Poly, mono, and unison play modes with glide
• Quietest-first voice stealing and note-on de-click for clean polyphonic playing
MODULATION MATRIX
• 2 mod slots per destination — assign via radial picker on long-press
• 10 sources: LFO1, LFO2, Filter Env, Amp Env, Mod Wheel, Velocity, Aftertouch, Random, ArpStep, ArpVelocity
• 21 destinations: filter cutoff, resonance, oscillator levels, drive, LFO rates, envelope times, and more
• Animated color-coded arcs on knobs and bars on faders show modulation range in real-time
GENERATIVE ENGINE
• 16-step sequencer with pitch, gate, velocity, probability, and repeat per step
• Euclidean rhythm generator (Bjorklund algorithm)
• Markov-based pitch transitions with configurable memory
• Bounded mutation engine with deterministic seeded randomness
• Motion Arp — playable chord-motion generator with 5 modes, 8 motifs, and 6 action pads
• Programmable internal tempo with tap tempo
• Long-press keyboard to set sequencer root note
• Host tempo sync, MIDI Clock sync, latch mode, swing
PERFORMANCE
• On-screen keyboard with pitch bend and mod wheel faders (standalone)
• Selectable keyboard range (25/32/37/49/61/88 keys) with octave shift
• MIDI Learn — long-press any control to assign a CC, with built-in default mappings for core controls
• MIDI Learn profiles — save and switch hardware mappings independently from presets
• Pitch bend, mod wheel, aftertouch (channel + poly), and sustain pedal support
• Sample-accurate MIDI rendering
• MIDI Clock sync for standalone mode
• 33 factory presets across 7 categories (Bass, Drone, Lead, Percussive, Sequence, Texture, Arp), with curated mod matrix routings and MIDI demos
• User preset save, load, rename, delete with categories
• Import `.slpreset` and `.slsndpack` files shared from Files
AUv3 PLUGIN
• Loads as an instrument in Logic Pro for iPad and other AUv3 hosts
• Full parameter automation
• Host transport and tempo sync
• Free/Sync transport modes — play sequencer or Motion Arp independently or locked to host
• Complete state save and restore (including modulation matrix and Motion Arp settings)
What's New in Version 1.1.0
Motion Arp is here. Hold a chord and hear it turn into living musical motion — no step pattern required.
SpiceCore now has three ways to generate notes. The existing 16-step Sequencer and evolving Mutation engine are joined by **Motion Arp**, a playable chord-motion generator that responds to what you actually play. Hold a triad, choose a motion mode, and the arp traverses your held notes with real musical intent. Change the chord and the arp voice-leads into the new pool smoothly, or restart on the next bar, or carry the contour over — you control the behaviour with the Memory macro.
Five motion modes cover different musical characters: Climb, Fall, Pendulum, Order, and Voice-lead. Two rhythm engines give you straight subdivisions with swing and gate, or switch to Motif mode and pick from eight curated musical gestures — from classical Alberti figures to cascading octave runs — each adapting to whatever chord you hold.
Six action pads turn the lower button grid into a performance surface: Freeze the current chord, send the pattern home, add a burst of ratchets, invert the chord, spread across octaves, or capture the last 16 arp events straight into the step sequencer for editing. Everything snaps to step boundaries so your gestures land musically, not glitchy.
The same four macro controls now retarget for Motion Arp: Mutation adds articulation variation, Density thins the phrase, Chaos opens the door to scale-passing tones, and Memory sets how chord changes behave. Two new modulation sources — ArpStep and ArpVelocity — let you route the arp's position and dynamics into any knob or fader.
Six new factory presets in a dedicated Arp category demonstrate the feature from clean utility to expressive pad textures. All Motion Arp settings save with presets and restore inside AUv3 hosts. Existing presets load unchanged — the arp is off by default and never touches your existing sounds.
