Multieffect Audioprocessor Seven studio quality effect modules for live usage and to enrich your iTunes music library. All effect modules can be used together chained in any order you like. The Chorus effect is a modulation effect used used to create a richer, thicker sound and add subtle movement. The effect roughly simulates the slight variations in pitch and timing that occur when multiple performers sing or play the same part. The Delay effect provides you with two different types of delay effects using two delay lines. With Sync mode the delay times can be set by note lengths and are then relative to the currently set tempo. The delayed signal can be feed back to the input for echo effects. You can select between a stereo delay and a ping-pong delay where the echoes bounces across the stereo field. The Drive effect provides you with different types of distortion from hard clipping to soft distortion simulating analog tube amplifiers and tape machines. The sound balance can be adjusted using a combined High/Lowpass filter. The distortion algorithm uses oversampling to reduce aliasing artefacts. The ParaEQ effect is a parametric equalizer with optional graphic editing of Lowpass/Highpass and Bandpass equalizer stage. The Flanger is composed of two independent delay lines with feedback for the left and the right channel respectively. The delay time of both delays is modulated by one LFO with adjustable frequency. For typical flanging effects the delay time should be below 5 milliseconds. The Phaser is built from an 8-pole allpass filter, which gives you a very short and frequency dependent delay time. This delay time is modulated by an LFO. The Reverb effect is used to simulate the sound reflections off walls in different kind of rooms. This reflections disperse the sound, enriching it by overlapping the sound with its reflection. This reverb parameter are accessible by the user: • Tail delay - Sets the amount of time that elapses between the direct sound and the reverberation tail. This time correlates with the perceived size of the simulated room. The adjustable range is from 0 ms to 300 ms. • Reverb time - The time the reverb takes to die away by 60dB after the end of the initial sound. This parameter correlates with the perceived size of the simulated room. The adjustable range is from 50 ms to 100 seconds. • Room size - The room size parameter sets the average distance between the reflecting walls. • Diffusion - The Diffusion parameter controls the echo density of the resulting reverberant sound. A higher value corresponds to a higher echo density which is in most cases more natural sounding. • Absorption - The Absorption parameter simulates the surface and air absorption of high frequencies. Due to absorption the reverberation time is shorter for high frequencies than for low frequencies. With higher absorption high frequencies will decay much faster. • Tail stereo - Adjusts the stereo image width of the reverberation tail. • Tail cutoff / tone - Lowpass and Highpass filter for the reverb tail. Summary of features: • Seven studio quality audio effects • AudioUnit for AUv3 compatible hosts. • AudioUnit full parameter automation. • Inter-app audio compatible effect. • Audiobus 3 compatible with state saving. • Apply multi effect to any song in your iTunes library. • Low latency live usage with mic and headphones. • Audio recorder • Ableton Link compatible.

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!
