Seaquence is a beautiful and lush sounding synthesizer with vast potential for creativity and exploration.

Its uniquely designed interface allows you to create music with swimming creatures in a stereo mixing dish. Multiple voices are heard simultaneously, resulting in layered, dynamic compositions. Seaquence's wide sonic template allows you to create everything from ambient drones to intricately layered rhythms and transients.

With its playful and colorful interface, even composers who are brand new to music will be able to unlock their synesthetic creativity. You can save your sessions, post and share them, and explore the Seaquence Galaxy to listen what others have shared and get inspired!

Upgrading to Seaquence Complete unlocks more tools, effects, and Midi i/o support.

Was a website years ago!!

I found these guys on a old site called stumble upon. I loved it now its a app good for them

Eriptron ,

Amazing little discovery!

What good is the Midi when DAWs like AUM does not recognize Seaquence. Anyway, it’s ‘almost’ a complete instrument. What is there is a lot of ‘sound’ fun with Seaquence synth. I wish that you could zoom in/out for the larger Creature populations. This really needs to be a Audio Unit to be used properly. Easy to use. Manual actually in the app (and a PDF version for download) would aid device ‘mobility’. I ‘especially’ like that the developer had the the insight to give Seaquence it’s own master volume control separate from the device’s! Performs solidly in background allowing using other apps while listening. Some of these sound patterns/textures are sick! lol

Needs some things.

Needs some things.
It needs to be able to make the voices play music after a certain amount of time that you can set up. Or play a certain amount of times when it reaches a certain time of day. Maybe even a thing where it can be random like if I set it up to play 3 times every 30-60 seconds. That would be cool. Also there needs to be an option where the voices wander around or at least set up a path for them. I would like to make them go where I want them to. I have paid 10 dollars for premium and I still wasn’t able to do any of those things.
