TTS1 GM 64bit VST alternative for use with SF2 / SFZ
I decided to share the results of my quest to find a flexible GM alternative to TTS1. There are few plugins that exist that support GM utilizing SF2/SFZ files or banks, but only a tiny handful that are 64bit VSTs. I found only one that is truly flexible and had been actively developed / updated. It is VSTSynthfont plugin created by a pioneer of this technology, the same developer that made Synthfont software.This is a fantastic tool/synth for playback of midi and GM based compositions utilizing your own SF2, Gig, SFZ files or banks. It is far more than just a VST synth.
It has many powerful features, such as:
64 Bit! (there is also a 32 Bit version available)
Individual channel transposition
Multi file SF2 bank support
Sorting instruments by "Instrument Type" with corresponding instrument
icons (given that the bank was assembled with GM structure).
Individual or mixed output for all 16 channels. You can actually
stream/record 16 independent audio channels simultaneously into Daw.
Lock channel sound
Mute / Solo tracks
And many other great features.
Demo is available at: http://www.synthfont.com/
There are simply no other tools like this to work with SF2/SFZ files that are 64 bit and have so many features. It is priced very
reasonably and most importantly the developer is a caring man, listening to customers and fixing bugs in a timely manner.
Scroll down to the middle of the page. The plugin is called: VSTSynthFont  P.S. Developer mentioned that people who bought original version of VST plugin are entitled for an upgrade at no cost.
P.S.S. It is still a bit young, so do not be to harsh on critique. If you find any bugs or have suggestions, please write to the developer directly, I am sure he will take it seriously.
Here are some screenshots of new version:
