Shepard tone/Barberpole effect

2008-04-11 by bellenger_a

I POST THIS MESSAGE AGAIN... MAYBE NO ONE SAW IT 

I'D LIKE TO HAVE SOME FEEDBACK


IF THERE IS ANY


Hello,

Does anyone here experiment with the Shepard Tone module (which is not available
anymore) or now also now with the A143-9?

I am interrested in this special nerver-ending rising effect.

If you use the A143-9, can you roughly explain if it works well and if the patch
takes lots
of module or not?

Thanks for yr eventual feedback


BEST,

ALEXANDRE

I have a shepard patch in one of our demo systems (with two A-103-3 for
endless up or down phasings and an A-135 for the mixing). It works very well
(but I think you wanted to have an answer from a more "unloaded" person).

The A-143-9 cannot to the same job as you do not need only the 90 degrees
phase shifted triangle or sine waves (to control the VCAs) but also the
rising or falling sawtooth waves (controlling the VCOs/VCFs/VCPs). Details
in the A-191 user manual.

Best wishes

Hi Alexandre

I had toyed with a shepard generator generated by CVs from a sequencer, 
sent to four VCOs, four VCA and found that it is not worth the effort. 
There is only one sound to be achieved with. If you want to hear it get 
YMO's great LP "Technodelic" and listen to "Loom" (most uninspiring 
piece on the record). If you really want it use, the possibilities of 
todays hard disk recording.

The A143, I do not know.

I bought a second hand 191 recently, and have only used it briefly with four oscillators (I only have four at the moment) The effect is pretty interesting, but I quickly realised that one would need 8 oscillators or filters to get a really solid effect, I am building some CGS VCO's, and once these are finished I'll be able to try out some other ideas. (I tried it with four osc 90 degrees apart, and also all at 45 degrees apart so I could examine a 'part' of the effect)

I did find that it may be interesting to add attenuation or offset to different phases of the sawtooth/triangle - especially with voltage control of these processes - to generate an ensemble effect with parts 'rising' or 'falling' in and out of it. The need to have 8 of everything does take its toll though!

I am, though, looking forward to playing with this further in the future once my modular is big enough!

So yes... what I get is that it takes a lot of modules, big patch... 8 
oscillators+filters+VCA...

OK...


Now I know a little bit more, thanks for all yr answers...

I'll stick to my patches of the moment and am very happy with my monster base 
prototype which arrived two days ago, works very good with the two little suitcases on 
top...

maybe I post some pics, no?

Best,

Alexandre
