What's new
Version 6.0 · 15 Jul 2026 · 3 months ago
• Pattern playback can proceed automatically to the next pattern, to a specific pattern, or even to a random pattern • A pattern can be defined as the default pattern for each playback restart • The loop count for chaining to another pattern increments only after all the pattern's lines have been fully read at least once • Redesigned preset selector with support for In-App Purchase packs • Two new preset packs available as In-App Purchases: Analog Sequence and Dance Horizons. Each includes 6 free demo presets. • Reordering the lines no longer causes synchronization issues between the lines during playback • The pattern player has been revised to fix issues with automatic sequencing that could, in some cases, cause a step to be skipped • Minor bugs fixed
