Pulseq vs EchoSketch

Pulseq is a multi-stage MIDI sequencer built for techno, acid, and experimental electronic music. It drives your external synths and AUv3 plugins over MIDI. Made up of 1-16 "stages", each stage carries its own note, velocity, gate behavior, and length. Chain scenes together into full arrangements. Use Pulseq as a standalone app or as an Audio Unit MIDI effect inside your host. SEQUENCING Build patterns from 1 to 16 stages. Each stage sets its own note, velocity, gate mode, and length in pulses. Let a stages hold for two or three pulses, and hear the loop come alive. PITCH & SCALES Pitch comes from each stage's note, guided by root and scale. Seventeen scales are available. Snap Notes to Scale keeps emitted notes in key; turn it off and stored notes play exactly as entered. GATE MODES & RHYTHM Gate mode is the character of each stage: Off, Single (one trigger per stage), Multi (retriggers every pulse, or every 2nd, 3rd, or 4th), Prob (fires by chance), Long (holds to the end), and Prog (a pattern you draw across up to 16 steps). Add Swing from 0 to 100%, shape Gate Length from tight and clipped to legato, and turn on per-stage Glide with global Portamento. PLAY & SPLIT MODES Play mode sets direction: Forward, Ping-Pong, Random, and Fixed. Split mode changes form: run a single lane, alternate lanes A and B by repeat counts (Serial, to build AAAB patterns), or run both lanes at once on two MIDI channels (Parallel) with an independent B clock multiplier. CC MODULATION Up to eight CC lanes drive filter cutoffs, mod wheels, or any destination that accepts MIDI CC. Lane values are per-stage, and every new lane starts with Don't Send so adding one can never surprise attached hardware. CLOCK & TRANSPORT When hosted, Pulseq follows the host transport and clock. Standalone, an internal tempo from 20 to 300 BPM drives playback, with clock divisions from 1/1 down to 1/32 plus triplet and dotted options. Apply Changes controls when live edits take effect: Immediate, Next Pulse, or Next Bar, for deterministic performance. SCENES & CHAIN Sixteen scene slots capture the full musical setup: stages, root, scale, tempo, split, and CC lanes, while leaving your user configuration intact. String scenes into a complete track with the Chain editor: set per-step lengths, loop the whole chain, and hand scene changes to the timeline. STANDALONE & AUV3 Use Pulseq as a standalone app or as an AUv3 MIDI effect. It runs in AUv3 hosts such as AUM, Drambo, Logic, and Cubasis.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
