Arpzite is a 49-key synth arpeggiator.
Choose your notes, select a pattern (up, down, up-down, random), set the BPM, and transpose up to ±24 semitones.
Hit play and it loops seamlessly.
Switch waveforms on the fly (sine, square, saw and more), tweak tempo, change notes, shift patterns in real time.
Press record and Arpzite captures everything exactly as it happens, exporting a .wav file with all your changes preserved.
