MIDI data glitch with soft synths

Hi Soens,

Unfortunately, soft synths, and even some hardware synths, don't all implement all cc responses.

Sound fonts can be limitted too. And yes, conversions are not always 1 to 1.

Depends on what you are doing, there is such a thing as the "sound engine" of a Synth.

One with a good powerful engine, and free, is Proteus VX, it comes with many useable sounds, plus they can be tweeked, etc.

Not too simple, but does have a lot of features, and does not have many of the limitations that sond fonts or variants have.

The other thing is tht many of the simpler synths don't seem to have  much technical documentation available, for instance the "MIDI implementation chart"   would answer many questions, but where is it?

In brief, some of the things you encounter, like no response to "tuning" may be that it is not implemented, same for Pitch Bend, which usually does some, but not too much, or not too well. Remember tht soundfonts and what you derive from them is limitted. Interpolation can't do perfect, or lacking, when the data is not there.

But, could be something else, of course, but what I mention is based on being through some of that, and also is based on the minimum information that you post.

Just some thoughts, basically.
