Until recently most music software only allowed working with the same 12 notes, equally divided over an octave. Whilst microtuning additions have broadened this considerably, it can still be cumbersome to get all plugins and external synths in tune, until now...
The MTS-ESP Suite equips composers with tools to get everything tuned quickly and accurately, as well as presenting entirely new compositional methods.
Change notes or chords whilst they’re being played, transpose all instruments at once or morph into an entirely different tuning system - the possibilities are endless. Discover more about tuning and get detailed visual representations in real-time, or simply get everything tuned correctly in record time.
The MTS-ESP Suite provides the computer musician with an intuitive toolset for rapidly composing and finessing microtonal pieces. Existing MIDI compositions can be easily converted to a different tuning system and given an entirely different emotional context. Working on new compositions is made nearly effortless.
