After finding copies of GigaPulse VST on eBay for only $99.99, it was too good a deal to pass up. All the online stores are selling it for around $249.00.
GUI: Nice interface, very intuitive and user friendly.
Sound: My only other experience with a convolution reverb is with SIR. Both are great sounding reverbs, but I prefer GigaPulse because you can change microphone simulations, microphone to source distance, and stereo/surround separation using multiple microphones; and I think it sounds a little better.
Features: GigaPulse has virtually no latency, so it can be used live. You can use multiple impulse responses in a cascading fashion. The microphone selection list looks to have at least 25 different microphones. I especially like the Neumann U47.
Docs: The documentation is a compiled .CHM file, although I would prefer a paper manual. But the software is so simple to use that you can probably figure out how to use it without a manual.
Presets: The onboard presets are very nice and cover a wide range of room types, studio quality electronic and plate reverbs, and several unusual objects like a metal broiler and a ceramic pot. Very interesting hearing a Mellotron coming out of one of those!
Support: I haven’t needed to contact Tascam support, so I’ll give them the benefit of the doubt.
VFM: For what I paid, GigaPulse is a steal. For what the online stores are selling it for, it’s probably still a good deal since it’s only 1/2 to 1/3 the price of some brands.
Stability: It seems stable; at least it hasn’t crashed so far. You do have to be careful of feedback with some settings though, and using one of the downloadable .WAV impulse responses from the many websites offering free ones makes it even more critical that you be careful. The .WAV files seem to be louder than GigaPulse’s native formats.
I’ve downloaded several free reverbs and demos of commercial reverbs, but I don’t think I’ll be using them any longer. This one does the job for me.
