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.

I don't normally comment but this guy looks like an aspiring developer of synth apps which is what I want to do. I just wrote my first electronica tune with this app. Great job :D the interface is reminiscent of early trackers but it is deceptively powerful. Only things to add would be an export by email option, and my iPod touch 4G added a tad bit of static to the exported file, but amazing job. Buying shape synth on impulse due to the quality of this app. :)

Cool tracker but please add horizontal support!

I like this but could really use horizontal support for both iPad and iPhone. Superior to Nanoloop!

A Fun little app

This is a fun little app, and I like it.

For the most part it works great, but when recording with the play head, it doesn't matter what octave you're set to, it always snaps back to 0 when it plays through. The only way to get anything above or below is to toggle to "note at", (unless there's a setting I can't find). Because of this, it would be good if there were some way to change the octave of a note after it's been placed.

Also, when you flip it into arpeggio mode, tapping on the the options doesn't always work. It's a little wonkey, you have to be really fast and snappy with your selections. Other than these problems, it's a cool 8-bit music app.

I tried to contact the developer to let him know instead of writing a review, but this is the only way I could find that he may read it. Providing an email for stuff like this would be a helpful thing to do too. If you do read, this and work on changing it, thanks in advance, Erik! If this stuff does gets fixed, I'll change my review to 5 stars!
