The corresponding values in FluidSynth commands are a bit different.
The scale in QSynth is 100:1, except Width that is 1:1
Here are the limits in FluidSynth:
* @param roomsize Reverb room size value (0.0-1.2)
* @param damping Reverb damping value (0.0-1.0)
* @param width Reverb width value (0.0-100.0)
* @param level Reverb level value (0.0-1.0)
There are also 5 presets (rev_preset 0-4):
/* name */ /* roomsize */ /* damp */ /* width */ /* level */
{ "Test 1", 0.2f, 0.0f, 0.5f, 0.9f },
{ "Test 2", 0.4f, 0.2f, 0.5f, 0.8f },
{ "Test 3", 0.6f, 0.4f, 0.5f, 0.7f },
{ "Test 4", 0.8f, 0.7f, 0.5f, 0.6f },
{ "Test 5", 0.8f, 1.0f, 0.5f, 0.5f },
So, the following values for QSynth:
> Room: 65
> Damp: 18
> Width: 76
> Level: 75
Are equivalent to these FluidSynth commands:
rev_setroomsize 0.65
rev_setdamp 0.18
rev_setwidth 76.0
rev_setlevel 0.75
