Title: Can't suppress default Voice for Melody (neophyte question) Post by: smrz on December 31, 2023, 07:12:07 AM I'm having a problem changing the Voice of a Melody. I'm probably making a trivial mistake but I can't figure it out.
I've defined a Melody Quote Melody Define M0 \ 4 c- 80; \ 4 d- 80; \ 4 e- 80; \ 4 f- 80; If I play it with the notes Quote 1 C 2 C 3 C 4 C it plays with a default voice. I tried changing the voice using Quote Begin Melody Sequence M0 Voice Cello End (entered before the notes). However, when I run this, I get the notes played with a cello and with the default voice. I can't figure out how to suppress the default voice. Any advice would be appreciated. Thanks PS The full mma file is Quote SetMIDIPlayer fluidsynth -a alsa -m alsa_seq -i /usr/share/sounds/sf2/FluidR3_GM.sf2 Tempo 60 Melody Define M0 \ 4 c- 80; \ 4 d- 80; \ 4 e- 80; \ 4 f- 80; Begin Melody Sequence M0 Voice Cello End 1 C 2 C 3 C 4 C Title: Re: Can't suppress default Voice for Melody (neophyte question) Post by: bvdp on December 31, 2023, 05:29:43 PM Not sure exactly what you are trying to do here (other than confuse me on the last day of '23 ... which you succeeded at!), but the mistake is in how you have defined the Melody strings. The syntax for the notes in a Solo or Melody are NOT the same as that for a "regular" sequence >:D
So, in your definition of MO Code: Melody Define M0 \ you have actually created the notes C- and G# (note 80). So, you are getting some very interesting harmonies :) If you want to micromanage note volumes (actually they are velocities, but that is a different discussion) you have to do it like this: Code: Melody Define M0 \ BTW, I think the notation above is slightly deceiving since it implies a 4 bar sequence. Better would be: Code: Melody Define M0 4 c-/80; 4 d-/80; 4 e-/80; 4 f-/80; And, since the duration is being repeated: Code: Melody Define M0 4 c-/80; d-/80; e-/80; f-/80; Since you are dropping all the notes by a single octave, try using the OCTAVE option when you create the melody (Octave 3 or Octave 4) leave out the "-"s. And, finally, since the velocity is just using the default: Code: Melody Define M0 4 c; d; e; f; Hope this helps.

With the correct syntax, my problem is solved. (FYI all I'm doing is trying to learn how to use Melody). I promise no more questions until (at least) 2024.
Have a good new years and thanks again. |
