Evolver is a performance tool for creating multi-layered evolving sequences of sound. At its most basic think of evolver as a 4 lane sequencer which creates automatic accompaniment from notes and chords as you play on your MIDI keyboard, but it can also be used to create elastic evolving soundscapes where audio samples seamlessly merge into one another to create highly complex and original sounds.

At the heart of evolver is a sophisticated wave synthesizer and sequencing engine which can create dramatic hard hitting transitions of sounds or merge sounds to create seamless transitions that evolve in time to the beat. It has 4 sequencer lanes which can run independently and mixed together using the real-time controls or over MIDI. When you play a chord on your MIDI keyboard for instance, each of the 4 sequencer lanes will take those MIDI notes and translate them into a musical sequence of sounds which are combined together and synced to create a form of automatic accompaniment.

Evolver can load its own multi-layer patches or import them directly from Chameleon. These patches can be layered using the 4 sequencer lanes or split over a virtual keyboard. You can assign key zones, transpose them, assigned MIDI channels and velocity levels, set latch options etc. You can also load in your own one shot samples and lay them end on end to create evolving atmospheres or backing soundscapes. These samples can be looped or be free running with definable start/end and loop points using our non destructive editor.

We also included a third sound source which lets you build sounds on the fly by overlaying harmonics to create anything from traditional sine, square, triangle, saw waves to complex detuned oscilators. These can be used in conjunction with multi-samples or one-shot-samples within the same sequencer lane. You can even randomize a complete sequence of harmonic sounds which when pieced together create some very unique and dynamic voices.

Each sequencer lane can be up to 64 steps in length, each step has independent timing, pitch, volume, gate, probability, sample source etc. so the scope of what is achievable is vast. Each sequencer lane has its own ADSR, VCF and LFO which operates on all sounds within its lane, as well as being able to change the underlying settings for each sound source.

Evolver also includes an ARP function which can be run in one of the default modes or you can define your own fingering patterns to be used to enhance your playing style.

Create your own sequences, lay down your MIDI notes in your DAW and have Evolver automatically play along to your chord sequences, automatically locking to the host tempo. Sequencer events can be fixed or transposed allowing you to create percussive and drum backing using a single lane.

What’s New

Version 1.18

1.18 B41

Long pressing on the Load and Save buttons now performs a RESTORE and BACKUP of Performance and Sample banks.

If you have a Performance bank that relies on external samples, place the samples in a group of the same name and back those up too using the above procedure. This means that distributing a performance bank will also require a sample bank be provided IF you have used your own samples.

Long pressing on the New button opens the Sample Pool to allow imports via drag and drop.

You can now drag and drop sample folders from the Sample Pool window to the Files App. This is useful if a Performance bank uses custom samples. Make sure the Performance bank name and Samples bank folder name are the same to avoid confusion to end users.

Great update to an awesome app!

Stellar customer service from this developer: I had noted in my first review that the app was deep, flexible, and creative--but that it lacked a mode that allowed the musician to play Evolver like a true keyboard instrument. Less than a week later, the developer released this update with the free sync option! Now we get both an option to sync to the host tempo for latching perfectly synced sequences AND the free sync mode to play Evolver like a traditional keyboard Instrument. Simply an amazing value for the money. Just buy it already!

Developer Response ,

Thanks for the feedback. Since this is an AUv3 intended to work inside a DAW the ability to sync to tempo is the most important aspect of the program. Lanes running none sequences or triggering samples do start immediately, but each lane that is linked to a sequence have to be queued and played locked to the host tempo as it stands. I will look into adding an option for those not wanting this. During delveopment I tried both methods, and decided this was the best choice, but I guess it doesn't best suite those not wanting to run it hosted inside a DAW.

Korg wavestate in software?

This thing is better than having a new korg wavestate it is way more flexable and easier to program. It excels at creation of sequences with way more options than any sequencer offers change samples change timing this thing is a masterpiece an absolute must have. Developers have already added new awesome features buy it now it’s unlike any other.

I want to love it.

But notes get stuck and won’t stop playing. Using progressions with it but then it’s seems to find a midi note that never ends till you hit panic and then that note always plays when you try to play something else. Very noticeable on the default strings that load into AUM. I LOVE SO MUCH ABOUT THIS APP. But this bug makes it unusable at times. It seems to happen when other apps are sending chords, like chordbud2, and it happens when using other host, like sands or Audiobus.
