MESA+ - ADD v1.2 (Pc)

ADD vs 1.2 available for download

ADD 1.2 Update Highlights:

Add has now a powerful Arpeggiator. It automatically creates new sequences in real-time by combining MIDI input (preferably chords) and a midi clip.

LFO waveform can now be stored into a specific folder for a easy re-loading.

Scale graph can now be saved and loaded.

The clip key-range is now stored in a clipset file for all clips, clip file now contains only midi data informations.

Bug solved: changing Vst presets caused crashes in certain hosts.

ADD is a new and innovative multi purpose phrase-sampler VST2.0 compatible, which combines a powerful sampler (Sound Engine) with a real-time phrase sequencer (RPS). ADD has been equally designed for use in a live performance or as a creative compositional tool; it enables you to quickly create original sequences while improvising with your midi-keyboard. ADD is 8-part multitimbral, each part containing its own RPS and Sound Engine. Add comes with its own unique sound library, which provides sequences and sound-patches. These are constantly being updated and can be accessed on our website.

The RPS has been designed to enhance and inspire musical composition. Amongst other functions, it can be used to harmonize or re-arrange music directly using your midi keyboard. An easy and intuitive editor maps sequences within midi notes ranges, ready to be triggered via midi in several different modes. Midi effects such as Quantize-swing or Humanization have been deeply studied in order to match midi sequences in any type of musical style. The RPS allows you to setup phrases for each patch. These phrases can be short clips, arpeggios, drumloops or complete tracks. The RPS is actually a set of eight independent polyphonic sequencers. The output of each sequencer is sent directly to the according patch-sampler. The phrases are triggered across an adjustable key-range and support many runtime features such as transposing.

The Sound Engine works like a PCM tone generator and it is composed of 4 Keygroups, each of them with a separate synth engine. This allows you to easily combine and layer sounds in order to rapidly create new and sophisticated timbres. An integrated Keygroup editor makes it a simple task to load and map your samples.
