Dario,
While I would never discourage anyone from using Lilypond, what you want has been done by Hal Leonard Publications in its Music Minus One series. https://www.halleonard.com/series/MMONE?dt=item#products Mark From: lilypond-user-bounces+carsonmark=ca.rr....@gnu.org [mailto:lilypond-user-bounces+carsonmark=ca.rr....@gnu.org] On Behalf Of Dario Marrini Sent: Thursday, March 16, 2023 3:09 AM To: lilypond-user <lilypond-user@gnu.org> Subject: [OT] help about some questions Hi lilypond friends, I'd like to create an orchestral midi collection, for playing piano concertos with a MIDI accompaniment. The first difficulty is transcribing orchestral scores, then, I wonder if someone could suggest me a pdf2midi or pdf2score app or online service that could help; at this moment I'd be interested in Prokofiev Piano Concerto n. 1 and Beethoven Piano Concerto n. 3; I tried the online service of MuseScore but I got a 'score not compatible' message (I'm using the imslp.org <http://imslp.org> score) Second difficulty will be getting an interactive mode about playing midi orchestral score, even without thinking to a 'follow me' mode, listening to audio solo part (I think it'd be very difficult to implement), I thought I could create and additional track, with just a few notes to play, and then finding a way to concatenate other midi events to those special notes, to get a synchronous mode with solo part (played by human) and midi orchestral part; even in this case (I'm not a such good code programmer) I have no idea if it could be possible and how. I'm a pianist and piano teacher, this kind of solution could improve very much the teaching level and the final piano and orchestra exam; indeed, it could be a development idea, creating a web site to offer this service Hoping this idea could be interesting for someone, I wait for your help or even thoughts regards dario m.
