Title: Aquaboy with ddt & mod mod audio samples
Post by: hoyager on December 10, 2010, 01:59:33 AM
SO here's are some samples, a bit experimental, but you can clearly hear the character of the delay. Used as a send from a desk on a rhodes, no processing or amping so you're just hearing the delay and the rhodes.

Mods include;

R15 = 68k (delay input volume?)
R31 = 39k (self osc point)
C23 = 1n box parallel with 1000pf ceramic

The two domes near the switch are connected to the delay time pot, so the glitchyness is coming from grounding those out.

Its not pretty on the inside, so I'll leave that one out I think...

Wow, these are great clips. Really trippy. I dig the glitchiness you've got going on here. Thanks for sharing!

sweet, can i ask how you implemented the contact points?

Sure, one has a wire connected to terminal 1 of the delay time pot and the other to terminal 3

I wonder what would happen if you put a couple of back to back diodes between those pins, instead of ground out the delay directly. I might have to investigate.

Sounds great. Thx

I was wondering wether the clock chip could somehow be 'programmed' to change the delay time in a stepped pitch fashion. One of the best delay sounds, I reckon, is having a switch for long and short times and adjusting the time so the step between results in an interval. A 4th works really well (more notes stay 'in'), but it would be amazing to be able to choose which interval the delay time and subsequently which pitch the feedback would change to.

I imagine this would be easier to do with a digital chip but if its possible with the analog it'd sound so much better.

With the domes its quite hard to control, one is a bit less than a 3rd, the other does nothing but both together shorts the pot out I think..

Maybe a rotary switch with different resistors attached? I guess that would be the easiest way to get something close. But I was kind of thinking along the lines of somehow making the clock adjust the time in semitone steps, that way the pitch change would always be relative, musically speaking (western)

Just thinking, out loud.
