epicMIDI

iOS / iPadOS · 0.2.18 · standalone + AUv3

A MIDI studio that fits in a pocket
and talks to everything else.

Sequencer, clip bank, piano roll, dual-manual performance surface, circle-of-fifths instrument, and a mixer that hosts third-party AUv3 generators and effects. External MIDI is first-class. iPhone and iPad. TestFlight beta now.

epicMIDI SEQ page
SEQ — pad grid, for live performance.

Six pages, one session

SEQ

A pad grid that launches patterns. Loop, one-shot, or hold. Drag tiles, individualize clips, intuitively.

BANK

MIDI clip library with folders for easy access to your favorite sequences. Drag a clip onto the pattern bar to use it in you project.

ROLL

Piano roll with draw / box / drag, snap, velocity and per-note probability, CC1 / pitch-bend lanes. Song loop is bars × time signature; clip length is STEPS.

PERF

Upper and lower surfaces, each independently keys, XY, knobs, or faders — dest, channel (Ø = off), scale, and a PM / VV left rail.

HARM

One or two circles of fifths. Each circle has its own dest, channel, layout, rings, and held notes.

MIX

Standalone only, w/ Audio Engine On. Load App Store AUv3 generators and effects. UI expands under the mixer row (no floating window). Mix keys, pitch, and mod go only to the expanded plug-in.

What it actually does

Pattern bar

Always on. Play / stop, SEQ vs PAT (grid vs selected clip — also drives the roll). One empty pattern on a new project. Clock cluster: time signature, song loop in bars, metronome.

MIDI, not a toy

Input port + In CH (Ø / Omni / 1–16), thru, internal or external clock, panic. Dest and channel are per surface — no master Out CH. Console shows the surface that spoke. Background audio keeps sending when you leave.

AUv3 both ways

Standalone hosts third-party AUv3 generators and effects (MIX). Inside AUM / Logic, epicMIDI is a MIDI processor only (aumi) — it sequences, it does not nest-host or render a synth. MIDI leaves through the host’s event block.

Files

Project, bank (clips + folders), clip SMF, and Type 1 project SMF (one track per pattern). Type 1 import splits to clips. Export bakes transpose.

Engine Off / Dummy / On

Off = pure MIDI (dummy synth does not run). Dummy = onboard sine. On = AUv3 host + MIX — standalone only. Inside another host, On is refused; you stay Off / Dummy.

Built for fingers

Pinch-zoom the roll, paint velocity, hold chords on the circle, gliss the manuals. No mouse required.
