[linux-audio-user] ANN: bristol 0.9.5-60

Bristol has been updated with a user configurable ARP 2600 synth. It has the
usual pre-patching as the original and, additionally, outputs can be
redirected to arbitrary inputs. This was a few changes to bristol to adjust
the engine buffer management for data that may feed back on itself, and
additionally a few extra operators for electroswitches, reverb and ring-mod,
etc. The envelope follower has not been tested at all and not all the patch
possibilities either as there are honestly too many to go through - about
600 possibilities with just a single cable.

The biggest changes were in the GUI. To support the user patches an extra
layer was added for their representation, then this was converted into a
transparency layer so the cables can be layered over the GUI to allow
control of the parameters without them 'getting in the way', then the cables
were coloured perhaps somewhat randomly - yellow patches carry signal left
to right, red cables carry signal right to left when see from the user
interface.
Once that was done I put in a cheesy watermarked logo - you can clear it
with the 'l' key or use the '-logo' option on the command line, but the
effect was too good to miss out on. The transparency can be toggled with the
't' key to allow you to foreground and background the layer, and 'o'/'O'
will adjust the depth of opacity. Load memory number 17, and play with the
'o' and 't' keys to get a feel for how the interface works. To patch, select
an output (the jack sockets light up for outputs) and then select an input
(these are just 'momentary'). This will direct the new engine routing
algorithm for each voice and then paint in the GUI. To clear a patch just
select either jack socket at the cable ends.

The net output of the synth is reminiscent of the sounds from the BBC
Radiophonic Workshop's greatest ever hit - the theme tune to 'Dr Who'. If
you don't know what that is don't worry, it's perhaps a bit obscure. The
original was composed on the elder brother of this synth - the ARP 2500 of
which the BBC had a few, so the results came as a pleasant surprise.

Graphics can be seen on the sourceforge homepage. Downloads as well of
course.
