Read full description

Chameleon is an AUv3 compatible sampler instrument plugin for your favourite DAW. The program can run as a standalone app in order to record audio samples from the internal microphone or professional audio interface. It also supports incoming Inter-App Audio connections for sampling directly from other iOS applications, however it is primarily intended to be used as an AUv3 Instrument plugin for applications such as Cubasis, AUM, Auria, Meteor, Gargeband etc. The plugin can additionally be loaded as an AUv3 effect in order to record audio passing through it from other AUv3 Instrument sources, which makes it a very versatile and useful tool. So what is a sampler? A sampler is a device that allows you to imitate other instruments with just a few short audio snippits. Although it comes with a library of presets it also allows you to create your own. You do this by recording multiple audio clips and mapping them to the notes on a MIDI keyboard and Chameleon does the rest using a sophisticated pitch shifting algorithm to fill in the blanks. Recorded samples can either be layered or mapped freely over a 7 octave range and saved as individual presets. Presets are then organised into custom categorised banks which can be exported and shared with others. Just think, you can sample all your favourite synth sounds and carry them around on your iPhone/iPad without the inconvenience of lugging heavy gear around with you. Sample anything from musical instruments to vocal snippits, drum machines or ambient noises. The possibilities are endless. Recording is incredible easy. Just create a New Patch and press record. Chameleon will wait for you to play a note before recording begins. Once recorded press the LEARN button and tap the note range on the virtual or MIDI keyboard to map the sample. Repeat this as many times as required, tweak the settings and save your patch. Additionally you can setup loop points with the ability to apply crossfade. If all that sounds too complicated, just press auto sample and let Chameleon do all the sampling for you. Chameleon also has a quite sophisticated arpeggiator which allows you to create complex mixtures of notes and chords with glide, hold and re-triggering options. On board reverb, digital delay and chorus effects are available to give your samples a more polished touch. We also include 4 touch pads for quickly dialing in on a sound or for easy effect automation. Configurable touch ADSR and modulation options are available too. Chameleon can also import audio samples using iOS Files integration or you can make use of Copy / Paste to quickly drop one of more samples into a patch. You can also freely edit samples using the built in tools such as normalise, fade in, fade out, crop, clear options etc. You can run Cameleon as a standalone app and map external MIDI keyboards (Bluetooth MIDI support also included) and perform audio sampling outside of your DAW. This is provided for convenience since you can't record input when hosted as an AUv3 Instrument plugin. Yes some DAW's have built in samplers which only have the ability to playback libraries provided with the software. Chameleon allows you to built your own libraries of sounds and share them with others. There's a budding rapper in you dying to get out and we have just the tool!

About

Attack Softener

This audio effect plugin removes the initial attack transient of notes, allowing for synth-like sounds from various instruments. It functions like a transient shaper but can silence pick sounds for fast music, enabling clean solo tones without distortion.

Highlights
  • Removes note attack transients
  • Creates synth-like instrument sounds
  • Functions like a transient shaper
  • Silences pick sounds for fast music
  • Enables clean solo tones without distortion
  • Preserves original instrument tone

Attack Softener is an effect that fades the beginning of each note you play to remove the attack transient. This allows you to make synth-like sounds with almost any instrument (guitar, bass, piano, etc.) HOW DOES IT WORK? It functions similarly to a transient shaper. Unlike a transient shaper though, it can bring the volume of attack sounds down to near zero quickly enough to silence the pick sound of an electric guitar in very fast music. WHAT IS IT USED FOR? It works with any instrument but we really like to use it with electric guitar. We recommend the following effect chain: Guitar -> Attack Softener -> Compressor -> Reverb. The combination of the attack softener and compressor is especially nice because the compressor keeps the volume balanced when playing clean solos but heavy compression intensifies the pick click noise, making it inappropriate for many styles of music. With the Attack Softener placed before the compressor you can get a nice, even clean solo tone that doesn't have punchy hard pick sounds. This allows you to play solos with a clean tone, where normally you would have to use distortion or overdrive to get sustain, now you can get that distorted "light touch" feel without the harshness of distortion. MORE TECHNICAL EXPLANATION OF HOW IT WORKS A transient shaper creates two volume envelopes. One rises immediately and falls slowly; the other rises slowly and falls slowly. The difference between these two envelopes indicates how far the volume should be reduced to silence the attack. However, changing the volume very quickly usually causes noise in the sound because of volume changes that happen naturally during the sustain part of the notes. This plugin is different from ordinary transient shapers because it combines several new methods to help it differentiate between real attack transients and other volume changes, and it uses dynamic filters that adjust the response time to ensure that it can respond quickly without introducing audible clicking sounds when the volume changes. IS THERE ANY OTHER EFFECT LIKE THIS OR IS IT SOMETHING NEW? EHX makes a pedal called Attack / Decay that does something similar. There are several other pedals that also do swell effects. All of them are designed for long fades and slow playing except the EHX one, which can operate faster by separating each new note onto its own audio channel using spectral processing. That spectral note separation distorts the tone signficiantly. This Attack Softener plugin is the only effect we are aware of that handles fast picking while preserving the original tone of the instrument.
