P930 Lunar Lander goes beyond a delay and beyond a plate reverb. It is a space-shaping instrument built to create depth, motion, and musical emotion with a level of control rarely found on iOS. Its reverb engine draws from the character and behavior of classic studio plates such as the EMT-140, and the spacious diffusion style heard in units like the Lexicon 224, while adding modern bandwidth shaping, harmonic excitation, and advanced routing. The BBD delay brings analog-style movement, widening, slapback, and rhythmic echoes with modulation, filtering, and optional noise. Push the plate for bright metallic shimmer or ease the input for warm, vintage smoothness. Blend delay and reverb in series or parallel, enhance the wet path with P42-style saturation, and use mix laws, ducking, and stereo tools to place your sound exactly where it belongs. Highlights • Plate engine inspired by classic EMT-140 behavior • Diffusion and tonal shaping reminiscent of early digital classics like the 224 • Analog-style BBD delay with modulation, regen, and filtering • Triple saturation (Plate, Delay, Output) • Series or parallel routing • Advanced ducking for vocal and mix clarity • Multiple wet/dry blend laws • Ping-pong, stereo offsets, and phase tools • AUv3 support Lunar Lander is not another effect. It is a new way to shape the space around your sound.

ChordMapMidi holds the better App Store score, 5.0 against 4.3.

Written reviews complicate that: 53% of ChordMapMidi's written reviews are positive against 74% of P930 Lunar Lander's, so the app with the better star average is not the one people write more warmly about.
ChordMapMidi ships an update every 8 months, P930 Lunar Lander every 5 days. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
