EXACTEMENTE . I CALL IT "BIT-REDUCTION" AS IT APPROXIMATES THE
(KORG ? + OTHERS ?) DIGITAL EFFECT . i THINK THATS WHAT kORG CALL IT .
LITERALLY, IT IS SAMPLE RATE REDUCTION , AND HAS SIMILAR
PROPERTIES , ESPECIALLY AT CERTAIN CLOCK FREQS OF REDUCED BIT
RESOLUTION SOUNDS.

YUP , ANALOG/ DIGITAL REALLY I SPOSE YOU MIGHT SAY.

YOU LOST ME PAL .I'M NO BOFFIN . I HAVE GOT THE BEST RESULTS USING
TONAL VARIATIONS OF THE SAME SIGNAL .DIFFERANT AUDIO INPUTS IS
LESS "MUSICAL" (VOMIT) A LA R/MOD , FREQ. SHIFTER ETC.
DUNNO QUITE HOW EITHER THE DETUNING/PHASE RELATIONSHIP AFFECTS
OF "SLIGHTLY DETUNED RAMPS" THO' .SOUNDS LIKE ALL GRIST TO THE MILL
TO ME.

YES , A CHOODESNY "NICHE" - ONLY ONE DEAR READER WAS INTERESTED
IN EVEN ASKING ABOUT THIS SORTA 'TRONIC-FOOLERY/EXPERIMENTATION...
SO ,THAT DEF. BEARS OUT YOUR THOUGHTS THERE....

P.K


The STS Serge is an excellent assortment to get deeply into complex

NO KIDDING AROUND THERE... i HOPE THIS IS WHAT PEEPS SEEK WHEN
THEY "BUY SERGE" . WISH SOMEONE MADE THE BUCHLA 200 & 300 SERIES
MODULES STILL. GOD BLESS REX PROBE (NICE NAME TOO -SORTA ITALIAN PORN
STAR NAME - KING PROBE-GEDDIT....SO I'M TOLD ANYWAY.................)
SOMETIMES I WONDER THOUGH.....

A PANEL A DAY HELPS YOU WORK ,REST & PLAY ......AS I LIKE TO SAY .
HEY ,IS THE GEEZER WITH THE 20 PANELS OUT THERE ? YOU LUCKY BOY -
YOU CAN PLAY WITH A DIFF. PANEL EVERY DAY FOR WEEKS .WANNA SWOP
LIVES ? LOVE TO HEAR 20 PANELS "TALKING"
SEB, i TAKE IT YOU DIG A MALENKY BIT OF FEEDBACK
LOOPING /CROSS-CROSS MODULATION.(SPECIALLY AS i SEE YOU HOLIDAY AT
THE EMS "PUTNEY" SITE TOO.)
THIS COMES BACK TO MY ASSERTIONS OF THE INHERENT MISCHIVOUS
QUALITIES IMPLIED BY THE "INVITATIONS" FROM MATRIX PATCHING .A SERGE
WITH A MATRIX MOTHER PATCHBAY .NOW THAT'D BE A TRIP .EMS DID MAKE
MATRICES A LA SYNTHI BUT WITH 16 IN + 16 OUT JACKS (MAYBE BIGGER -49
X49 ? TOO .LETTING YOU CROSSPATCH ANYTHING TILL THE COWS COME HOME.
ALL HORRORSHOW STUFF.
