Sinusoid vs AB Mix Check

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. +++ 3 tone channels: sinusoid, square, triangle, saw, pulse (75%, 50%, 25% or 12.5%) +++ 1 drum/noise channel +++ Stereo pan +++ Amplitude envelope (attack, length and release) +++ 2nd oscillator for fm and ring modulation +++ Vibrato +++ Pitch glide +++ Resonant filter +++ Arpeggio/stutter +++ Tape delay +++ Bit/samplerate crush +++ Per note ability to override all channel audio parameters +++ Copy/paste between devices on the same network +++ Save and share projects using “open with” and files app drag’n drop +++ Export to songs to AIFF +++ Core MIDI, Bluetooth, IAA MIDI, AUv3 MIDI +++ Audiobus, IAA and AUv3
