Arpist arrives this morning. Looks useful, handy, fun (free) …
Arpist is an arpeggiator designed for MIDI hardware, iOS instrument apps and use with DAWs. Arpist processes MIDI input from an external MIDI controller, iOS instrument app or from chords that you build in the Keyboard View, and generates musical arpeggios and rhythms based on your settings.
You can create rhythmic dynamics using the variable-step Rhythm Grid, in which you can create loud and soft steps, play chords for emphasis and skip steps altogether.
Arpist stores settings in snapshots, called Song Blocks. You can organize your settings across multiple Song Blocks to sequence through various patterns and rhythms while you play.
Key Signature and Transpose controls allow you to diatonically transpose your patterns, in any key, in real-time.
Advanced features include MIDI Remote Control and MIDI Clock Send and Sync. With MIDI Remote Control, you can manipulate Arpist’s controls from your keyboard, even when Arpist is in the background.
Note that Arpist is a MIDI generator, not a synthesizer. Enjoy Arpist with your favorite keyboard or iOS synth app!
