As others have pointed out every soft synth has strengths and weaknesses. Some soft synths are multi-timbrel and polyphonic. Others are mono-timbrel and polyphonic or mono-timbrel and monophonic.

Multi-timbral soft synths can produce two or more timbres (also called sounds or patches) at the same time. Soft synth examples include the Microsoft GS Wavetable included in most Microsoft Windows editions, the PG Music modified VSTSynthFont64 Gordon Scott mentions, Coyote WT included with Band-in-a-Box and the no longer available for download Cakewalk TTS-1 Peter Gannon recommended in another post. Hardware instruments also can be multi-timbral such as many consumer electronic keyboards, synthesizers, samplers, and music workstations.

The PG Music provided multi-timbrel soft synths use the General MIDI, or GM, patch list to associate patch names with patch numbers. That way a guitar is always a guitar and a piano is always a piano for example.

Normally you want to select a multi-timbrel soft synth in the Band-in-a-Box Synthesizer/Sound Card selection. (Ctrl+E > MIDI Driver) See 2nd screen shot.

Multi-timbrel soft synths are also polyphonic meaning they can play more than one note at a time. However there are also Monophonic soft synths that are multi-timbrell. Plogue Sforzando plugin is an example.

There are also monophonic soft synths that can only play one note at a time but this is not the place to discuss them.

Look at the screen shots below and you may find it easier to understand what the settings are and how they are associated in Band-in-a-Box.
