I'm starting to adjust my opinion of this project quite a bit. (In the negative sense) I started this hoping to get a relatively low part count, decent sounding, adjustable reverb, and so far it's proven to be more of a interesting wierd effect board rather than a nice reverb. I've been making all kind of adjustments with the sound and I've been intrigued many times (Weird note swell effects, resonating plate kind of sounds, odd bouncing reflection messes) but never truly enthusiastic about any of the "normal" reverb sounds I have managed to dial in. I think Belton had the right idea when they stuck three chips on there, I think three is the absolute minimum where you can a decent sounding reverb-reverb.
Perhaps this will just be another one of those "it's not worth it" projects, as Taylor concluded. It's sure starting to look like it to me.
As for the FV-1, I am sure it has great capabilities but that's not my kind of area. I'm not actually looking to build a reverb for myself, unless it would turn out to have special interesting qualities that set it apart... Rather, I am building this as an exercise in design, an opportunity to mess with interesting results, and a chance to give people another option. The FV-1 is a predesigned, program only chip that really offers no design challenges in incorporation. The PT2399, however, being a building block for more complex designs, interests me much more. Mark Hammer said it well: "(The hardware approach) simply provides a usable and approachable platform for them to explore their own ideas. "
I'm not much of a builder, (I rarely assemble something unless I absolutely want to use it) but more of an experimenter and learner, many of my projects are for personal education only and never get past the breadboard stage.
