What’s new
Version 1.0.6 · Updated July 7, 2026
What's new: • Unified pads — all 16 pads are interchangeable sample or MIDI slots. Convert any pad with a long-press; your sound and MIDI settings are both kept, so switching back restores exactly what was there. • New onboard drum kit — 16 fresh, original sounds (kick, snare, toms, hats, clap, cowbell, shaker, cymbals, percussion, and an acid-style FX bass note) fill every pad on a new project. • First-launch demo groove — open the app for the first time and press Play to hear a full pattern built from the new kit, showing off locks, conditions, micro-timing, and effects sends. • Step recording — arm STEP mode and the pads stay live: every tap writes into the current step and automatically advances to the next one. Use the on-screen REST and CLR controls to skip or clear a step without missing a beat. • Export your patterns — bounce the current pattern straight to a WAV file and share it, with every parameter lock, micro-timing nudge, and effect baked in exactly as it sounds live. • KEYS voicing — MONO, POLY, and LEGATO modes for playing samples chromatically. Play full chords in POLY, or glide smoothly between notes in LEGATO, right from the same key grid. • Master compressor, finished — a smoother glue compressor with a new makeup-gain dial and a live gain-reduction meter so you can see and hear exactly how much it's working. • True stereo filtering — stereo samples now filter with independent left and right channels for a cleaner, wider sound. • Filter and effects cleanup — the filter type selector now matches what you actually hear, dead knobs were removed, and the delay gained a ping-pong on/off switch. Fixes: • Fixed a bug where missing sample files could silently break a project; pads now clearly show what's missing and recover automatically once the file is back. • Fixed playback sometimes not starting on the very first tap after opening or reloading a project. • Fixed early-timed hits and retriggers occasionally landing a step late. • Fixed the delay effect not staying in sync when tempo changes. • Fixed KEYS presses that could occasionally register a touch without triggering sound — key playing is now noticeably more responsive and reliable. Thanks for playing — keep the feedback coming.
