Violin Sound font Out of Tune

The B5 to E6 in the violin soundfont is dreadfully flat

Indeed. Essentially, the problem is that the sample is about a quarter-tone flat for about three quarters of a second, then shifts up to be in tune. If you tune it up about 25 cents, then it will be in tune for about three quarters of a second, then shift up to be a quarter tone sharp.

To my own violinist's ears, FluidR3's violin is unparalleled in the SoundFont format—everything else sounds bad compared to it. For that reason, I don't like the idea of throwing the whole thing out and rebuilding with new samples. Instead, I found an easy way to fix these bad notes, and I'm really happy with it.

The WAV file attached to this post is neither more nor less than the faulty sample from FluidR3Mono, trimmed at the point where the pitch changes (using Audacity). That's the only change I made to it. Polyphone does the rest.

So, here are complete instructions for anybody reading along:

Things you'll need

1. Download the complete SoundFont (the SF2 version, not SF3) from https://musescore.org/en/node/94611.

2. Download "Violin B6(L).wav_.zip" attached to this post, then extract the WAV file from the ZIP archive.

3. Download and install the free Polyphone SoundFont editor from http://www.polyphone.fr/.

How to fix the tuning

1. Open the SoundFont in Polyphone.

2. Go to File > Import samples… and navigate to wherever you saved the replacement WAV file.

3. When the dialog appears asking if you want to replace the sample, click "Replace All."

    (Now the inconsistent pitch at the end of the sample has been removed.)

4. Type "violin" into the filter at the bottom left, then under "Samples" in the sidebar, select "Violin B6(L)".

5. Go to Tools > Sample > Auto loop.

6. Under "Instruments" in the sidebar, select "Violin."

7. Look across the grid for the "Violin B6(L)" column, scan down the column for the "Tuning (cents)" row, and enter "21" in the cell where they intersect.

    (Now the pitch has been adjusted correctly.)

At this point, you can save the SoundFont, and set it as MuseScore's default as described at https://musescore.org/en/handbook/synthesizer#soundfont. Enjoy your beautiful violin sound!

hello - I clicked both links you have - it seemed to download the same thing twice - Polyphone1.7-win64 .exe , Upon opening it , I tried to open Soundfont>importsamples> it is a dead field/icon in other words - no reaction- I'm doing something wrong here
sry - I'm justa musician , not a great computer person.

re: Polyphone - does one have to Load a whole piece or a part to fix the pitches ?
( i.e. a flat violin sound) To make it clearer in my question , do I have to load the violin sound onto Poly , or bring Poly into Muse ...

sounds like a lot of working trouble to get it right, but could be well worth it ....thanks

Sounds to me as though you'd be better waiting for the official fix - the whole violin instrument is designated for replacement due to the unsatisfactory nature of the current samples.

But if you want to have a go yourself, then feel free.

Polyphone is a soundfont editor.

Once you have installed it you should open the soundfont you want to edit with it - in this case (presumably) the default FLuidR3Mono soundfont.

Come back here if you're still having trouble.

So the plan is indeed to replace the whole instrument? As I said before:

To my own violinist's ears, FluidR3's violin is unparalleled in the SoundFont format—everything else sounds bad compared to it. For that reason, I don't like the idea of throwing the whole thing out and rebuilding with new samples.

That's up to and including the violin in General User, Timbres of Heaven, and Sonatina Symphonic Orchestra, as well as a dozen others (including string-specific SoundFonts). This gives me the idea that it's really, really difficult to get a good sounding violin with exactly the right attack to sound good on fast notes as well as slow. FluidR3 seems to have achieved the impossible and perfected that magic sound, and I'm worried about the difficulties of starting from scratch and getting to that level.
