Op 133 Studios

As of Spring of 2015, Op 133 Studios is please to host apps by Nick Collins on our account. Op 133 plans to continue to make these popular applications available on iOS, and will update for new versions of iOS as best we can. Currently available:

TOPLAPapp - TOPLAPapp is a sonic puzzle based around a virtual machine for sound synthesis. This machine accepts a few valid instructions represented by the letters T, O, P, L, A, and p, and you control it by placing each command letter within a grid, along with setting some associated parameter sliders. The machine rushes through the instruction set to create output sounds, which are usually of a somewhat noisy character, hopefully interestingly so. The historical antecedents include instruction synthesis as pioneered at the Institute of Sonology in the 1970s, and the live coding movement, of modifying a running program as it acts. This app is intended for those interested in more experimental sonic art: don't download unless you are open to stranger computer music sounds ((http://www.toplap.org).

RISCy - RISCy is a drag and drop synthesizer puzzle full of sonic perturbation. You live code via the limited instruction set in the lower part of the interface; drag out tokens to the top area to build your synth graph, drag a token back off the top area to remove it. Each token has an aural consequence, and some special tokens also change the nature of the hidden graph connecting active tokens; puzzling out these relationships is part of the fun. You'll be able to make lots of noisy sounds as well as generative sequenced patterns. Press ! to clear the graph and reset; press ? to get a random starting point. Download RISCy if you are open to stranger computer music sounds, and avoid it if you just want diatonic melodies and piano sounds!

Cryptoclash - Cryptoclash is a strange generative synthesizer, which translates letters into sound. By typing in a string of up to 20 letters (a-z), you set up the states of the sound engine, which are represented as roaming particles. Every time they collide, things can change! Use the accelerometers to change gravity, and tap on a ball to give it a velocity boost. Each time you choose the source string, you create a new sounding patch. Some sounds are noisier, and others more meditative; keep exploring and you'll hear interesting new tuning systems (such as 26 notes per octave), and different amounts of synthesizer feedback.

BBCut - Create remixes of anything in your Music Library with the help of BBCut. This app uses live beat tracking to automatically attempt to align itself to the structure of your music (it will work best with strongly rhythmic music in 4/4, but can also have interesting consequences on other sources...). You can have automatic or manually triggered cut-ups, and bring in a comb filter effect as well for additional havoc. Lots of fun will ensue.

Concat - Concat is a 'concatenative synthesizer' operating on live audio streams. The current sound input is matched to the best fitting stored audio in recorded buffers; for example, you can control playback of other sounds via your voice. The matching is based on four timbral features, and you can choose the size of the matched segment played back, from immediate small grains to larger segments. Concatenation comes from choosing lots of these grains one after another to make novel output sounds. This feature-based granulator lets you create up to five buffers of around 20 seconds each; try capturing your friends' voices, the sounds of your environment, and more...
