PlayArp

PlayArp is an expressive MIDI arpeggiator designed for musicians who want to play patterns, not just start them. Instead of behaving like a static utility, PlayArp turns your phone into a performance surface for external synths, hardware setups, and software instruments. Touch, movement, XY position, pressure, and multi-touch interaction can become part of your sound and performance. Whether you are jamming with a hardware synth, controlling plugins, or exploring new melodic ideas, PlayArp gives you a more direct and playful way to shape arpeggios in real time. Why PlayArp feels different: • Playable arpeggios instead of static playback • Real-time expressive MIDI control • Designed for performance, jamming, and experimentation • Built for synth enthusiasts, electronic musicians, and curious producers • Works well in hardware, hybrid, and studio setups Features include: • Expressive MIDI arpeggiation • Touch-based performance control • XY interaction • Pressure-based modulation where supported by the device • Adjustable pressure response inside the app • Multi-touch logic • External synth and plugin control • Adjustable timing and speed • Creative random functions for variation • Gate and velocity variation • Chord-based arpeggios • Custom note sequences • A fast and immediate workflow for live use PlayArp is made for musicians who enjoy movement, gesture, timing, and feel — not just menus and programming. It can be used for techno, ambient, house, experimental music, melodic jams, and many other styles where motion and expression matter. Use it to: • create evolving arp performances • play chord-based arpeggios • build your own note sequences • add life to external synth lines • explore rhythmic and melodic variation • use randomization for unexpected musical results • jam with a more physical connection to sound • find new ideas quickly PlayArp is especially suited for: • synth enthusiasts • hardware jammers • dawless performers • producers looking for a fresh interface • musicians who want more expression from MIDI Pressure response depends on the touch hardware and display capabilities of each device. PlayArp lets you adjust and control how pressure modulation behaves, so you can adapt it to your setup. The focus is not on overwhelming feature lists. The focus is on musical interaction. Play the arp. Show your sound. Built by an independent synth enthusiast for people who love expressive electronic music tools.
