Organ Donor

More stuff from the Organ from beside the road! Now we have a rather nice spring reverb -- the actual spring is in turn isolated from the frame by another spring assembly and there is a nice acoustic bag for the whole thing. A bit tempted to investigate a valve (tube if you must) option! There is still booty to be rescued what's more!

Some new Ideas...

Possible keyboard scanning/arpeggiating for the organ keyboard, with velocity of course...

...and the Sound Comes out of There...

Back to get more organ waste... Seems in resonable condition despite the water stain -- probably good enough for my ears anyway!

Top Octave

The fruits of the Organ salvage... a top octave generator... these are becoming inceasingly hard to find. I have a design that i made that uses a PLD to act as a top octave generator but it is expensive, very power hungry and a pain to program...

e-waste

Well got a new keyboard from beside the road! Forbin will be pleased... Not the best action but it does have the kimbell allen style springs that are stretched between two contacts. We may be able to do some velocity sensing? The mind starts to wander...

More Uncertainty

This is the Gaussian distributed noise. The steps are much finer on this output as it is summed from 15 resistors instead of the 8 from the linear distribution.

Source of Uncertainty 3

This is the stepped output which has a linear distribution. It is running from a 1000Hz clock and giving a nice 0->10V range.
