Ops is a modular synthesiser designed to make it easy to create and explore sound interactively with a touch screen. Ops does away with patch cords, instead using a system of connected blocks with a clear signal flow.

The blocks, called ops, are joined together into structures by dragging and dropping them on screen. Structures can easily be copied and varied to build-up rich, interesting results.

There are ops to perform a wide range of functions, including interaction, signal generation, effects processing, control, audio input, sample playback and record, MIDI input, and pitch and rhythm manipulation.

What’s New

Version 1.1.1

- sample record and playback ops

Modular made easy

Ops makes modular synth/sound design fairly easy - even for novice sound designers. The modules snap in place and are really easy to understand. It doesn’t take long at all to have something on there screen that not only sounds cool, but is also easy to see what is happening.

I would give 4.5 stars if I could right now. There are a couple little things that I’ve contacted Jonathan about and he has been very quick to respond.

Long words ,

Overall very promising!

A couple of minor things I have found so far. The oscilloscope- great tool, but I would like it at the top right corner if possible. It's mostly because I depend on it so much. The second thing is the menu. It keeps picking up objects when I try to scroll. Other than that full speed ahead!

Very cool

I wish there was a desktop version. An interesting paradigm shift in the UI. Easier to wrap your head around than PureData because each unit already 'works'. Check it out.

@dev: perhaps a freeware version with no save?
