MOTM

I know some of you guys went! How about a report?

I was happy enough with my VCA till I wanted to have both an EG and an LFO controlling it... Any thoughts? Any suggestions about a possible mod adding a second CV maybe with an attenuator too?

You can mix control voltages using the MOTM-830 mixer.

This would be the obvious choice but for those who struggle to purchase the 
few modules they have, or for those who don't want to use up valuable 830 
mixers just to get a second input on their VCA, a simple mod would be nice.  
Assuming he is talking about the 110 then he could also use the ring-mod 
portion as a VCA and then run it into the VCA portion and then he can control 
one with an EQ and the other with an LFO and then no mixers are needed.

Use the 830 Mixer to mix the output of the EG and LFO then send that 
to your VCA...

Or this has worked for me, too: EG controls CV of 110 then VCA OUT 
goes to YIN, while XIN gets the LFO feed.

OK,  I'll take a shot at this.  If I understand the circuit correctly, the
voltage applied at PIN 12 of the 3330 controls the overall gain of the VCA.
Paul has already built a summing node on the front end that sums the voltage
from the GAIN pot to the voltage from the CV MOD pot.  I see no reason why
you could not add a 3rd input to that summing node.  The only problem is
that you could end up with a resulting voltage that drives the VCA into
clipping if you turn both controls to max.

As I see it, the modification requires only 3 parts.  1 - add the input jack
2 - add a CV2 mod pot, connect the pot and jack just like J1 and VR1.  3 -
add a resistor from the wiper of new pot to the common point at R1 and R5.
Since a LFO is typically 10 volts swing, I think this resistor should be
100K or somewhat larger.  100K would cause this CV input to have about 50%
of the effect as CV input 1 (as I see it).

It seems to me if you use the LFO input, then depending on whether you have
a "+/-" or "0 to -" voltage you might have to adjust your "gain" pot off of
the "0" set point some.

Paul, Care to comment right or wrong?

Disclaimer:  I am not an engineer.  I am not telling you to modify your
MOTM-110.  I am offering this modification suggestion for the purpose of
discussion and learning.

When I had posted the question it was 3 a.m. here in Italy so I went to bed. This morning I found at least three valid approachs suggested:
1)mixer 2)RM input 3)LH's mod to the unit. 
Thanks to everyone... who knows maybe Paul will comment LH's suggestion.       Enrico

MOTM-830 Mixer

It was absolutely incredible!  The darkened planetarium was a great
backdrop to Robert's lush, evolving music.  He mixed some wonderfully
complex modular synth patches with some soft pads from "plain vanilla"
synths and wove in some acoustic sounds throughout the set.  The songs
were delieated by theme, and not silence - it was 90+ minutes of
constantly shifting audio imagery.

The (very large) MOTM modular that he had was the center of the
"orchestra pit", but he frequently went to a lap steel (the guitar-like
thing on a stand that the country music guys use all the time) and
brought sounds from it that were somewhere between a moan, a cry, and a
howl.  Towards the end of the set, he used three different wind
instruments to add a ghostly presence to the atmospheres.

The title of the performance was "Alien Zoology", and lying back and
looking at the star show I could see various life forms coming alive,
from little spacey-insects swarming around us, large herds roaming the
vast plains, underwater schools of sea creatures swimming by, and much
more. 

I believe the PA was playing in stereo - I can't wait to hear what
Robert is going to do with surround sound!  Sign me up for his first
5.1 channel DVD!  Also sound-related, the performance might have had a
little more impact if there were some subwoofers carrying more of the
low end.  Still, the sound quality was easily a 9/10 and I'm just being
picky.

Robert is truly a master of the ambient/atmospheric genre, and I think
it's unfortunate that he doesn't get more mainstream recognition and
popularity.  Then again, it's really nice to go to a small, intimate
show where you can meet the artist afterwards.

I'm looking forward to seeing him live again next year!

Graham

PS I think I saw some other MOTM'ers there, but it's been a few years
and my memory is fading at my old age of 30!

Anybody go? How was it? Hopefully no exploding modules on stage :)

Paul S.

It was excellent. A planetarium is the perfect setting for his music.

He started out his set with what sounded like sampled percussion and pads
accompanied by him playing live woodwinds and pedal steel guitar.

He gradually brought in more of the modular until it was generating most
of the sound. At this point it was really fun to watch him twiddle
knobs, and patch and repatch modules. 

Towards the end of the set the sampled percussion/pad/orchestral sounds
came back in along with his live woodwind performance.

Sorry, I'm not a good reviewer - the show was great!

listen to the r0b0t

I'm not sure if he has a Blacet MiniWave or not. I know that he 
(along with I) bought one of the 10 original Wiard MiniWaves made. 
They have a shorter pcb than the Blacet version. If he only has one, 
it's a Wiard.

If any list members attend, fill us in!

Paul S.

Well not Robert Rich but I just saw Stereolab in NYC's Town Hall. 14 hour drive total. It was 
great the only slight dissapoinment, if ever look up vintage or curent modulars on 
synthmuseum.com or vintagesynth, virtually every modular ever made has been used by 
Stereolab, on stage they had a voyager, a couple of nords, rhoads and a clavinet. But no 
modulars I assume that this was just common for traveling. But I bet they already or will 
have some motm in their collection soon. Now Im just gonna wait a month till the RR show

I went to the Robert Rich show last night in San Jose. It was awesome! The show was full with people. There where some great visuals. The music was very
