However, looking back, it was as though I learned Lilypond more for the challenge than the ease of notation. For the latter, I switched to MuseScore, which has developed dramatically and energetically over the years into what is now a mature and very capable notation app.

Recently I decided to try the newer notation app Dorico, because I love it's design principles, including keeping the fundamental nature of music (pitches and their durations over time) separate from the representation of music using glyphs and symbols on the computer or printed page.

This (video below) is my first finished project using Dorico, notating Seascape 1, a simple and brief piano piece, performed in the video using the Vidal MIDI controller keyboard and Pianoteq 9. The reverb used for the customized preset is the "St Nicolaes Church" impulse response from a Voxengo IR collection (free to download and use) from here-- https://www.voxengo.com/impulses/ -- The impulse response was imported into Pianoteq:
