Re distortion: I've got the RP355 for my MIJ Fender VI and the pallet of overdrive & distortion tones available via its various guitar amp & cab combinations breathtakingly surpasses the overdrive tones of the VT Bass I used to own. But of course the VT' kills the RP355 in the cleaner tones dept.
Hopefully the new BP355 will bridge the above gaps.

One more thing: while Digitech ships (Mac & Windows) software which can control the parameters of their various units via MIDI commands, for GNU/Linux users there's this unofficial offering:
"Control your Digitech effect pedal under Linux!
gdigi is tool aimed to provide X-Edit functionality to Linux users
Supported devices (list misses your DigiTech device? Please get in touch!):
* RP250
* RP255
* RP355

Hmm... The download link on that page is currently broken. Those who are interested in gdigi may wish to e-mail the author: <desowin@gmail.com>
In the meantime I have the gdigi-0.2.0.tar.bz2 archive from which I compiled an executable gdigi 2.0 application via these instructions:
"Setup: There're no distribution packages available for gdigi (you're welcome to package it for your distribution of choice).
In order to compile gdigi on Debian/Ubuntu system, issue following commands:"
Code:
sudo apt-get install build-essential libasound2-dev libgtk2.0-dev libglib2.0-dev libexpat1-dev
wget http://d10xg45o6p6dbl.cloudfront.net/projects/g/gdigi/gdigi-0.2.0.tar.bz2
tar xvjpf gdigi-0.2.0.tar.bz2
cd gdigi-0.2.0
make
./gdigi
If any GNU/Linux users here (I've found that gdigi 2.0 works well under 32 bit Ubuntu 10.10 with an RP355) want the gdigi-0.2.0.tar.bz2 archive (~122kB) please contact the author.
(If you can't get through to him, then PM me and I'll e-mail you a copy.)
The one important thing which gdigi
can't do yet is save tweaked parameters as a configuration file to a hard drive. However IIRC the author is working on this feature, which (along with alerting him to the release of the new BP355) is why e-mailing him would be a good first move.
It is worth noting that as of three months ago there was
no GNU/Linux support available for other competing multi-effects/amp modelling units. I looked...

And since the new BP355 is based upon the RP355, here's a thread I found to be helpful:
