About
Groove Train is a chord-groove practice tool by PartyKeys. Pick a progression (1-6-4-5, 2-5-1…), edit independent left/right-hand rhythm patterns, and play along with the drum machine — right-hand chords, left-hand roots, advance only when you play it right.
• Dual-track step sequencer: attacks, holds and accents per hand, with 4/8/16-step cycles
• Three practice modes: Strict (waits until you're right), Flow (never stops), Adaptive (limited wait)
• Nearest-voicing chords keep your hand in one position — focus on the groove
• Hi-fi multi-velocity grand piano samples plus a built-in drum machine
• Connect the PartyKeys Bluetooth MIDI keyboard for real-time two-color key lighting: orange guides your left hand, blue your right
• No instrument? Practice the full flow with the on-screen keyboard
• Save custom grooves on your device, import/export as files, bilingual UI (中文 / English)
