Here's the algorithm list first:
-Fading Parametric Equalizer - an EQ with a kind-of-Exciter
-Dynamic Filter 1 - LPF and two EQs, all controlled by envelope followers
-Dynamic Filter 2 - BPF/multi mode filter plus a high pass filter in parallel, dynamically crossfaded, all controlled by envelope followers or envelope generators
-Extended Compressor Limiter - Expander/Compressor/EQ/Soft Clipper
-Channel-Vocoder - a 16-band Vocoder with attack/release per band (whoa)
-Exciter - actually, an Exciter + Gate
-Non-linear Saturator - EQ/bass enhancer/saturator/high-pass filter
-Percussion Synthesizer - looks like a 808 or a 909 from the schema
-Monophonic Synthesizer - 4 OSCs, three filters at once plus delay etc.
That's all algorithms. Now here's the problem - the synthesizer algorithms can't be triggered by external sources, only by MIDI. And I currently don't have a MIDI keyboard so I can't tell how they sound like.
The others - well, the EQ is kinda like an EQ. The Compressor works but I'd rather use an analog one (easier to handle). The sub-harmonic generator works well on guitar, not so much on bass. The non-linear saturator is used to emulate tape and tubes with varying degrees of authenticity. So, up to here we have a couple of good-sounding standards with sub-optimal usability.
BUT - there are the Dynamic Filters. The first one is already great, but the second one is incredible. It produces filtering effects from low-fi wah to subtle treble fuzziness, underwater-like sounds and everything in-between. All triggered from your playing with all envelope followers again fully editable. Very expressive.
I use the Dynamic Filter 2 on bass for some weird filtered sound (see below for an URL).
The unit has no digital I/Os. The converters are good though. Overall, no noise
I have some Sony stuff (both pro audio and hi-fi) and even the oldest stuff from 1992 still works great.
Hardware is top notch, extremely stable.
Overall, this is a unit without too many useful applications. Unless you own some synthesizers without filters (?) or are in desperate need of a monophonic synthesizer, this isn't a unit for everyone. Most of the algorithms are near-useless without MIDI control anyway.
On the other hand, if you are looking for this sound <http://eaio.com/misc/sony_dps_f7.ogg>, then try finding one. If you aren't, don't bother. You won't find one anyway
