Creative introduced SoundFont as an alternative to traditional samplers. It is compatible with most sound cards that support MIDI. This allows users to alter the envelope, filters and LFOs.
Nucleus a VST-based SF (SoundFonts) player that has 8 voices and can also be used as an envelope filter, BPM or BPM synchronizer. It also includes a graphic envelope generator, 2 LFOs and a ring modulator to enhance the sound quality during composition.
We must admit that the interface of this plug-in is fantastic. All parameters will be perfectly separated. This makes it much easier for people who have worked with this type of supplement.
Nucleus can be a good alternative if you already have SoundFont libraries.
