Euclidean Sequencer
Euclidean Sequencer is an alternative incarnation of the classic step sequencer that has become very popular in the modular realm. It is based on Euclidean rhythms developed by computer scientist Godfried Toussaint in 2004. Euclidean rhythms have their roots in Greek mathematician Euclid’s algorithm, which involves using the greatest common divisor of two numbers to place hits in a sequence as evenly as possible across a set timing divisions.
In practice this is actually simpler than you might think, and Euclidean Sequencer is a great way to auto generate complex musical sequences with no prior knowledge of how it actually works.
Euclidean Sequencer is an AUv3 plugin that can be loaded inside any popular host application that has flexible MIDI routing.
You can define up to 4 Euclidean rhythm parts, each part is referred to as a band. The bands are labelled A-D and colour coded RED, ORANGE, GREEN and CYAN. Together these 4 bands create a pattern, and you can create up to 16 separate patterns per song patch.
Since each band can specify its own note sequence and output MIDI channel, you can create some quite sophisticated rhythms patterns, driving 4 separate instruments at once. Even better you can seamlessly switch patterns to create even longer evolving sequences. Patterns follow a specified key, scale, or defined chord.
You can even use MIDI input to automatically make note sequences conform to the currently playing chords.
Euclidean Sequencer now supports 4 different modes, traditional Euclidean, PolyRhythm, PolyMeter and PolyTempo. We have many great ways to automatically generate complex rhythms making it an invaluable tool for experimental music creation.
Audio Shredder
This is a AUv3 compatible audio effect which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels.
This audio shredder does just what is says, it shreds incoming audio (usually strings or lengthy sustained chords) into bite size pieces, adds an envelope and passes through a filter of choice. The result is a gated staccato effect which you can shape into patterns or runs of quarter notes. These kinds of patterns can be heard in Trance / Dubstep / Hip Hop or other modern electronic music genres. You can control both left and right stereo channels independently, with control over pulse width, attack and release.
There are 4 difference filter types (Low Pass, High Pass, Band Pass and Notch) which can be enabled, with independent control over cutoff frequency and resonance. You can even randomise new settings each step for some incredibly complex and pleasing textures.
Each quarter note can be independently triggered or you can join them together to create longer runs.
This plugin allows complete parameter automation and auto sync to master tempo.
Copperhead Synth
Copperhead is an AUv3 digital subtractive synthesizer plugin which draws its influence from the vintage synthesizers of the early 80’s. Only now we have multi-note polyphony, a build in arpeggiator, and a host of integrated audio effects. Copperhead features a custom String Machine, the ability to design your own custom waveforms, as well as supporting oscillator sync and various cross modulation effects. Cross modulation is a type of FM synthesis which can be used to morph simplistic waveforms into something far more aggressive and interesting.
At the heart of Copperhead are its two oscillators, which support all your traditional waveforms (SINE,SQR,SAW,TRI), as well as SuperSaw, Trapezium, and other user definable types. The app features pulse width modulation and supersaw, as well as a customisable string engine and the ability to create your own oscillator types.
The Voltage Controller Filter supports the usual LP, HP, BP and Notch filters in series or parallel configuration, as well as a couple of unusual ones like Formant which allows you to sweep your cutoff to create interesting vowel sounds.
Copperhead also features twin LFO’s with random and one shot functionality. It also supports Cross, Ring and FM modulators, in addition to low and high shelf filters.
One of the great features is the integrated audio gate, which allows you to generate stuttering audio right out of the box. Combined with effects such as Chorus, Overdrive, Delay, Reverb and Auto Pan / Tremelo, and the ability to specify effect order, you have a lot of control over your sound.
If that wasn’t enough, we also include a 32 step sequencer, with various mono and poly modes with direct control control of various synth elements.
We have a built in Preset Manager which groups presets into banks and groups, which supports drag and drop for easy import/export of presets. You can also access your favourites from a special popup menu, or via the built in quick search facility. Copperhead now ships with over 550 presets which cover just about every instrument category you would ever need.
Helium Editor
Helium is a lightweight AUv3 MIDI sequencer plugin designed specifically for AUM. It supports up to 16 tracks of unlimited length with the ability to direct output to 16 channels on up to 16 MIDI output ports.
One of the great features is the ability to import and maintain libraries of MIDI clips using Helium’s ‘Media Bay’. These clips are freely available all over the internet and may contain individual chord sets, chord progressions or drum tracks. You can quickly build a song by dragging and dropping your MIDI clips from the media bay onto your timeline. You can also save your own clips directly to the media bay to create your own personal MIDI clips libraries. Long press on a clip to preview its contents using the currently selected MIDI device.
Helium now ships with a library of over 7000 MIDI clips, consisting of every chord and chord progression you could ever need.
Helium allows many different ways to import additional MIDI clip libraries. Simply drag and drop your ZIP collections directly to your PC/MAC web browser and they are automatically unpacked into the clips library folder. You can also drag and drop files between the Media Bay and the iOS Files app.
Helium supports a sync mode called ‘Remote Looping’. This was something we recently introduced into our MultiTrack Recorder plugin and is very useful for breaking down the timeline into sections. You can define up to 12 loops which can be used to specify the locations of say the intro, verse, chorus, and outro within your song, then trigger these loops seemlessly in sync with the host tempo. Once captured, these loops can then be triggered by incoming MIDI notes.
A new addition to Helium is the ability to piece together loops into songs, so you just concentrate on creating a single verse, chorus, bridge etc. and piece everything together without the headache of having to re-arrange your timeline.
