delay and sample hold
delay and sample hold
one thing i discovered with my modified boss DD5, is that with the reverse kill switch engaged, i can get some interesting effects on the sample and hold settings of the CP251 (signal chain: MF101 into MF102 into DD5 into amp or board, with CP251's sample/hold output modulating the MF101's cutoff frequency). haven't analyzed what's going on exactly, but it seems to open the sample and hold up to some rather fun things, mainly by messing with its rhythmic aspect. also found that the S/H responds beautifully to very short (12.5 msec) delays with the feedback ALMOST at infinity (roll back the wet/dry mix to taste); this was with a DD3 (which i find easier to fob this effect with than the DD5). gives a nice, 'hindustani sangeet' sort of shimmer on the S/H; with the cutoff freq. reduced, one can almost muster a gamelan approximation, esp. w/ a bit of ring mod. i really like cascading delays...apparently so did mr. leslie- check out the tenth photo down on this link:

well, that's an interesting question. i would suspect the unusual effects i've noticed have come when the delay time was longer than the intervals between sampled tones, as set by the LFO rate (or expression pedal)...this, i imagine, would have the effect of selectively repeating tones, and without the dry signal, would by that fact alter the rhythm of the S/H pattern. but again, i admit to not being very scientific about it. i'll have to check it out with the 'other half' of my brain & get back to you. 

Wow. Amazing Leslie photos
In your Leslie photos, were the speakers, cymbals, etc controlled from the organ keyboards? What did all the hanging microphones do?
How did that cascading delay work? What did it sound like?
Thanks for posting the photos.

i thought all of the mics where there to pick up all the sound/reverberations from the organ thing. i assumed that all of the sound waves in the chamber made the hanging cymbol vibrate and produce some noise too, but in a real subtle way.
not about the leslie thing: i usually like to use the reverse setting on my delay at the longest setting (a little over 20 seconds) to try to get the best reverse tape effect as possible (though still really lacking). it's the shorter settings that seem to get really weird effects though. i imagine setting the s/h rate and delay time somewhat close (like 550 or 600ms for the delay and s/h rate at 2hz or whatever 2 cycles a second would be) would mess with the tempo in neat ways.
now all i need is a control processor to mess around with...

you're quite welcome- they're actually by a mr. charlie lester (http://www.137.com/), who would likely be one of the few people who could answer your questions, as sadly the amazing don leslie passed away in 2004. i missed charlie's copyright notice at the very bottom of the page (to my chagrine), but hopefully he'll appreciate what we're about here and not mind...

don leslie questions
all,
Not only was Charlie Lester ok w/ sharing the link to his neat photos, he graciously shared with me a bit of what he knows of Mr. Leslie's 'home studio' setup. enjoy...
Hi Lance,
Don Leslie was the consummate tinkerer. In fact, tinkering was precisely how he made the discovery that put his name into the annals of music history.
The organ in his home is a combination of windblown-pipe and electronic voices along with real percussions and some electronic ones as well. The reverb array was something he devised himself and worked incredibly well. The pipes and acoustic percussions were miked, and the miked signals ran though the bank of reverb and delay pedals.
The way the signal cascaded through them and then into the stragegically placed speakers around his large living room created an awesome, realistic reverb. I am not a technically oriented person so I couldn't tell you what exactly he did or how he did it; I can only say I have heard zillion-dollar reverb systems that paled in comparision.
(n.b. There were other reverb units for the electronic voices.)
