SQ4² is described as the ultimate "Scratchpad/Inspiration" tool. The idea is to extract the main parts of music into 4 different entities - TIME / PITCH / DYNAMICS / DURATION.
It has 5 main panels, MIDI, Audio, Inspire, Mix and Controller and each panel has 4 pages. Each page has four channels (sometimes called blocks). So there are 16 channels (blocks) per panel.
Features:
- Complete automation of VSTi parameters, through parameter changes / MIDI CC.
- Complete control over Timing/Pitch/Velocity/Duration in a independent way of each other (ideal for multi-rhythms/ever evolving melodies).
- Control over LoopEnd-points.
- Creation of Seamless loops / Performance recording.
- SampleLoop mangling.
- An inspiration panel to generate sequences in a few seconds.
- A transposer.
SQ4² comes in 2 flavours:
- SQ4²-I : controls your external gear through MIDI.
- SQ4²-II : controls VST Instruments.
SQ4 costs 29 EUR for the MIDI only version, 49 EUR for the VSTi control version or 59 EUR for both. A demo version is available for download.
