Sinusoid4.2.8 - App Store

Sinusoid is a tracker/sequencer sound machine inspired by retro 8 bit game consoles. It has 4 sound channels where 3 play tones and 1 plays drums and noise. It has audio parameters like pan, amplitude envelope, vibrato, pitch glide, a resonant filter and second oscillator for ring modulation and fm. Further sculpt the sound with an arpeggiator, delay and bit crusher. Export songs to AIFF and listen to them in the in app music player or share them with other apps. MIDI can be used to control parameters, play and input notes. MIDI out makes it possible to play other synths with sinusoid using Core MIDI, Bluetooth, IAA MIDI or AUv3 MIDI. Connect to other sound apps using Audiobus, Inter App Audio or AUv3.
