Noisy SD1-32

Noisy SD1-32

2007-02-22 by scottfree_01

Hello, I have a sd1-32voice synth that seems to be very noisy in 
recording situations. Seems to be noise particles after the sound. Is 
this a common finding? Is there a fix? Any help would be useful.

Thanks,
scott

re the noise from an SD-1.

I don't know if this advice has been offered on this group or not, but 
here's a MAJOR issue with the whole VFX/SD family. If you want the best 
signal to noise ratio out of the beast, the keyboard master volume 
slider needs to be up FULL. It is NOT a volume control (or attenuator) 
it is a digital controller of the dynamic range of the final output 
stage DAC, so there-fore, if you have the volume control set to 75%, you 
get HALF the signal to noise ratio the beast is capable of.  - be 
careful of that one.

but having told everyone that then you'll all get a better sound out of 
them and nobody will want to sell me theirs. Bugger. Ignore everything I 
just said.

cheers

VFX/SD-1 Noise?  Oh, man!  You got that right.  Have 6-VFX-SD/SD-
1's.  For years that noise bothered me.  Kept slider wide open as you 
suggest.  

Another ear nuisance did NOT occur to me until mid-1990's.  While 
(pulling an all-niter) writing one of hundreds of sequences, occurred 
to me Ensoniq's factory ROM Strings, Organ, Brass, etc -and- many 3rd-
party sounds were Pitch-Flat.  Guessing because they were written in 
Master Pitch of 440Hz.

Spent hours going through every patch, preset, etc.  Slightly tuned 
the 2nd, 3rd, etc. oscillator's up 2-10 cents each.  Next, compared 
tempered pitches to other piano/organ patches-whatever, then saved 
them.  Man, what a difference! 

Anyone else notice that *flat-pitch sound* in Ensoniq factory patches?
