Hallo !

2002-04-13 by obidiah2001

Greetings all from a new member and novice Sergeon. Any tips
on how to get my MidiCV converter (Encore Exp.) to track a 12
tone scale ? The Quantizer works with the TKB but when I plug
my expressionist into it it dosen't work right . (whatever "right"
means ! ) Going directly into an ocillator from the expressionist
works but dosen't produce a 12 tone scale without the quantizer
? Thanks in advance for tips or links to educational sites. - From

welcome the list, george.
i have both serge gear and the expressionist. the expressionist puts out a strictly quantised voltage at 1v/oct. there is no need whatsoever to involve your Quantizer module.
however: it sounds like you're having a grounding problem between the expressionist and your serge. rex, in fact, offers a special mod to the expressionist that will alleviate these problems. what you need to do is make sure you've got proper grounding via the ground lug on your power supply to your expressionist. one way to do this is to connect your serge ground to your mixer as prescribed by serge, then simply plug an expressionist output into any input on your mixer to establish proper ground. try this and let me know if you are then getting the correct 1v/oct voltages.

Wouldn't plugging any Expressionist output into a Serge CV interface do the
same thing??... if not that might explain some of the tuning problems I've
been having lately useing my MAQ through the expressionist to a STS CV
interface. The MAQ is grounded to a Serge power supply and of course all that
is grounded to my mixer but the Expressionist is not...... hmmmmm....
comments???

This grounding issue stuff really baffles me.

I use a Kenton Pro2000 Midi-CV interface which recieves Midi
from my sequencer and outputs CV into my Serge via the CVI interface module.

V/Oct tuning is rock-solid, gates & triggers and Midi clock all work 100%. I
haven't done
anything to ground them to each other. No ground hum issues... and nothing
is grounded to any 'mixer'
(the audio outs of the serge just go into a regular patchbay).

I'm getting a rack of MOTM stuff next month and have been advised by Paul S
to ground them to
the Serge PS using the STS supplied banana plug/grounding plug.

Could somebody simply and easily explain why these things need to be
grounded and what happens when they're not
as in the case of my Kenton.???

I'm not very technical , certaqinly no EE , but from my
understanding , sometimes you will get hum from having no earth
connection between the synth & power supply . Also , I believe it has
something to do with the stability of the system tuning wise etc.
Rex would give you a technical answer II'm sure.
In the USA I've noticed it will cause hum if not earthed more
easily , but the U.S. electrical system is less sturdy than here -
especially in (dis)regard to earthing .
When I connect my Fenix up , I earth that to the Serge power supply
& it has always been fine . I guess it depends what earthing & earth
loops your studio has already.

Same here.
Never any tuning difficulties just a loss in output volume if I haven't
connected my Fenix or Serge together carefully.
I've certainly never had to ground the midi-cv converter or ground my
banana systems to the mixer. Things are probably different from studio to
studio though.

thx for the help...

I was lucky enough to have my studio re-wired from scratch. I consulted
the 'studio wizard' guy who advertises in SOS. He told the electrician what
to
do and I've had NO earth hums whatsoever... it will be interesting to see
how the MOTM rack integrates with the Serge. First time I've mixed 2
systems.

OT - BTW - Sonic, I was introduced to your music by a mate who knew you in
Rugby - Graham
Holliday - back in '87. I think he contributed to a Spacemen 3 fanzine. He
lives in Hanoi, Vietnam now!
