GridStep vs ARC

GridStep is a professional MIDI step sequencer designed for clarity, control, and predictable results. It works as a standalone app as well as an AUv3 plugin. GridStep provides a focused grid-based workflow with explicit edit modes, per-step inspection, and one-shot generation tools. Every interaction is intentional, allowing patterns to evolve without ambiguity. Core Features Explicit Edit Modes - Dedicated modes for Notes, Velocity, Slides, and Mutes - Clear, consistent interactions across the grid Precision Grid Editing - Step-based grid with visible playhead and pattern length - Per-step inspector for detailed control - Efficient editing without leaving the main view Trigger-Based Step Advance - Advance the sequence using incoming MIDI triggers instead of the host clock - Enables irregular rhythms, external control, and non-linear playback - Fully compatible with standard clocked playback Controlled Generation - Pattern generation for notes, velocity, slides, and mutes - Apply generation globally, per lane, or per selection - Designed to support musical intent Performance-Focused Design - Deterministic, repeatable sequencing behaviour - Stage-safe interface optimized for quick adjustments - Predictable timing within AUv3 hosts AUv3 MIDI Effect - Works in AUv3 hosts such as AUM, Drambo, Logic, and Cubasis - MIDI-only design compatible with any synth or sampler Built for both live performance and composition, GridStep emphasizes stability, readability, and repeatable behaviour.

Eight tracks. Synths, samplers, drums. Play it like an instrument. ARC-24 is a groovebox for iPhone and iPad. Pads, loops, and a mixer in one place. Everything stays in key. Pick a key and a scale and the pads follow, so you can play fast without landing on a wrong note. Record a loop, keep overdubbing while it runs, and fix whatever you fumbled on the grid afterwards. Once you've got a few loops going, chain them into a song. Or leave the transport running and fire them off by hand from the mixer. • Eight tracks that sort themselves out. Synth, sampler, or drums, decided by what you play first. Overdub while the loop cycles. • Note and chord pads locked to your key and scale. Hold latches notes so they sustain. Pulse retriggers them on the beat. • A sixteen pad sampler. Import WAV, AIFF, MP3, M4A, AAC, or FLAC, pull audio from a video, or record through the mic. Chop it into slices across the grid, or map one sample over every pad and play it pitched, in scale or chromatic, at the original length or at tape speed. • Ten drum kits, from 909 and trap to lo-fi, boom bap, and hand percussion. Tune, pan, and level every pad. • Synth editing that goes deep enough to matter. 21 presets to start from, two oscillators, filter, envelope, and LFO when you want to build your own. Save the keepers. • 25 arpeggiator patterns, all of them in your key, from slow drifting phrases to sixteenth note runs. • A piano roll editor. Move, stretch, and delete notes while the loop keeps playing. • A real mixer. Faders, pan, mute, solo, and three band EQ on every channel. • Every track gets its own effects rack, not a shared send. Resonant low and high pass with cutoff and resonance. Compressor and gate. Distortion, bit crusher, ring mod, flanger. Tempo synced delay in digital, analog, or tape. Reverb with chorus and tape wow. Character for texture, air, width, and warmth. • Motion, so synth parts never sit still. Slow LFOs drift the filter as the loop runs, and Bloom opens the cutoff every time you play a note. • Song mode. Arrange loops into sections, or switch between them live from the mixer without ever stopping. • MIDI in from a USB or Bluetooth controller. • Export to WAV or AAC. • iCloud. Start something on the iPad, pick it up on the phone. Seven days free, the whole app. After that one purchase unlocks it for good. No subscription, no renewal, nothing to cancel.
