I've been busy, that's for sure.

The Freq Shifter was designed by Chris MacDonald; I think most of you know
who he is by now. I'm going to get my hands in it before it ships, but it's
mostly his baby.

The MIDI-CV is my answer to retiring the first Expressionist. It's going to
have more features and a slightly different topology. The 12 jacks are ALL
CVs, but the vertical line indicates a "pairing up" of channels when used as
conventional CV/Gate pairs. As you can see this one is 12 CV channels or 6
CV/Gate pairs. Not quite as big as the original Expressionist, but more
flexible in other ways.

I'm still going to update the original Expressionist code as planned, but
this development will occur at the same time. I know Dave B (among others)
has been VERY patient.

I have NO code in the Expressionist 2 yet. I've been busy all year on the
Midiman SurfaceOne. (I think it will demo well this week)

Price on both items is TBD, but they are looking something like this:

Frequency shifter: $389
Expressionist 2: $499

Come on by and say "hi!"

Frequency shifter? Yes!!!! Shifts through zero? Calibrated 1V/oct input? If so then this is a great price.

Bigger knobs on this one please. An oversized one for Manual Shift would not be out of place.

Is it digital?? In other words, how can you sell an analogue frequency
shifter that doesn't completely suck for only $389?!?

DACS Freque2 $1200 (exists, in stock and shipping)
Moog CE $1800 (vaporware, no one has actually seen one)

(To think, I've been asking manufacturers questions like this for over 20
years and not one of them has ever tried to have me killed :)

>Expressionist 2: $499

More VCO channels, and less money than a Pro4!!


I think Tony must be getting his parts for free or something :)

RE: [motm] more NAMM poop

2002-01-16 by Tony Karavidas

That was OLD MacDonald (his dad!)

Chris MacDonald is the guy that designed the MiniModular.

No it't not digital. It's PURE analog. There is some cost cutting to get it
to that price. The biggest thing is that it isn't a "through zero" type of
shifter. I've heard both, in fact Chris has a proto of each and I thought
for the extra trouble and cost it wasn't worth it. There are plenty of
expensive frequency shifters out there. The other "economical" shifters
don't have near the performance. For instance, there is German frequency
shifters that only goes down to 50Hz. Mine (Chris') is about .05Hz.

With a super slow shift, you get these neat continually rising sort of
effect from the audio. I'm trying to get a little system demo so people can
play with it at NAMM.

Parts, who needs parts?! Actually there are 200 components on this board.
Most all are surface mount.

I'll have to get my tag line updated in 2002!

Unless more showed up at the NAMM show, there are fewer choices than you
might think, and none of them will fit in an MOTM:

Serge makes two different units based on the Buchla 185/285, one with an
internal carrier built-in ($1,000) and another that depends on, but let's
you use, an external carrier ($1200). Either of which must be purchased as
part of a whole panel. The module with the internal carrier has 1V/oct CV
control but does not have oscillator outputs.

Analogue Systems recently announced a frequency shifter. You have to buy
their chassis to mount and power it, so in that regard it is not unlike the
Serge. It is a "clone" of the Moog/Bode 1630, and afaik no one has ever
seen one. So it is also quite similar to the vaporous Moog CE -- wondering
how much it costs is like asking how many angels can dance on the head of a
pin.

DACS makes the Freque2 for $1200. It's not similar to anything. It's a
complete unit, powered from the mains and enclosed in a 2U metal chassis.
It can be used as a frequency shifter or two separate ring modulators. The
VCO's respond to Hz/V from 0 to 15V, and all the jacks are in back, which
is less than ideal for use with an MOTM system. However, unlike all of the
other high-performance frequency shifters, it has the singularly unique
feature of actually being manufactured.

>The other "economical" shifters don't have near the performance. For
>>instance, there is German frequency shifters that only goes down to 50Hz.

Yes, this is what I meant by "doesn't completely suck", but let's not put
all German designers in the same basket!! While it is has the lowest
price, it can't go below the audible range _and_ its carrier suppression is
awful. This unique combination of "features" makes it absolutely useless,
imho.

>Mine (Chris') is about .05Hz.

That's very good!!

>With a super slow shift, you get these neat continually rising sort of
>effect from the audio.

Yes, the Dogpoop module is useless for "phasing" and feedback control,
perhaps the two most practical applications of a frequency shifter. At
most, dedicated feedback control units shift by only 6Hz.

>Everyone is free to comment on all of this stuff. I'm listening.

First off, since it is an analogue module, and the carrier is not merely a
figment of a microprocessor's imagination, I think Encore should add
oscillator outputs. That way you get both a frequency shifter and a
quadrature oscillator for your $400. Not to get all electro-acoustic, but
having an oscillator output would be very useful in shifting around a
particular "key", using one output against the input to "tune" noise, and
creating sounds in which the input has a mathematical relationship to its
output (where the input is the waveshaped carrier).

Will it include schematics?? While I doubt anyone would try to steal an
SMD design, the majority of MOTM builders are curious how things work.

I'm I correct in assuming that the "feedback" controls mix the outputs back
into the input??

What is the CV response of the oscillator?? Is it 1V/oct or Hz/V??

What is its carrier rejection??

Let's say you have a fox, a rabbit, and a head of lettuce...

Yep... I've seen it too. Even had a play with it. Very odd thing, but
thats the nature of the beast so to speak. I reckon I could get used to
it after a bit of practice.

Of all the small scale modulars, the Analogue Systems' ones seem the
most well made to me. Shame about the patch leads though.

Thanks for the pictures. Nice modular, I have a cabinet the exact same size, soon to be outclassed by a Synth of Doom Killer.

How well do the Schaeffer panels blend in with the MOTM panels? MOTM has a textured coating while Schaeffer panels don’t have this option.

Well as far as I knew, no one had seen one. Now I know better. Thank you
for the update.

RE: [motm] more NAMM poop

2002-01-29 by Tony Karavidas

Sorry for the huge delay replying to this. I've been really sick for over a week now.
The FS shown at NAMM is neither of those things, but one change that is being considered is having the local oscillator change from analog to digital, and this would cost effectively provide both features, and a wider range of shift. (Especially at the slower end) The multipliers would still be fully analog and so would the entire audio path. The price wouldn't change, but the ship date would slip. I think it would be a better product overall, but maybe other's would disagree.
Now's the time to speak up. Everyone I mentioned it to at NAMM thought it was a great idea.

I would much rather have the increased functionality and enhanced frequency
range that using the digital oscillator would bring.

I've oft wondered why we don't have more digital components in modules...and
I begin to think of the possibilities. Not that I'm going for a digital
audio oscillator or filter anytime soon, but considering some of the other
CV or audio signal processing capabilities..ooOOOOOooo...somebody do it now!

Willing to wait longer for a better piece of gear....

I'm going to order this almost as soon as it's available....projected ship
date?

Hm? You're saying it's not calibrated for 1V/oct?
When you say a digital oscilator, what exactly do you mean? A DCO? A value-lookup table? The only thing that makes me worry when I hear digital oscillator is the "stale, cold, frigid" effect.
But I have no idae if this would come into play, since I don't know how a frequency shifter works. Thanks!

Sorry for the huge delay replying to this. I've been really sick for over a week now.
The FS shown at NAMM is neither of those things, but one change that is being considered is having the local oscillator change from analog to digital, and this would cost effectively provide both features, and a wider range of shift. (Especially at the slower end) The multipliers would still be fully analog and so would the entire audio path. The price wouldn't change, but the ship date would slip. I think it would be a better product overall, but maybe other's would disagree.
Now's the time to speak up. Everyone I mentioned it to at NAMM thought it was a great idea.

Frequency shifter? Yes!!!! Shifts through zero? Calibrated 1V/oct input? If so then this is a great price.

Bigger knobs on this one please. An oversized one for Manual Shift would not be out of place.

RE: [motm] more NAMM poop

No it's not. Remember the local oscillator needs to span a range of 17 octaves ( not far off from Paul's ultra VCO, and that VCO alone costs $349 assembled. ) and so to get real calibrated CV, you'd need CV control of all that. In reality, you could choose a small range, but since this has application far different than an oscillator, calibrated CV isn't very important. What are you calibrating anyway? You're taking an input frequency spectrum and shifting it by X Hertz. As soon as you start to shift your entire harmonic relationship starts to get mangled, so really what's the point to CV control other than to allow modification of how "messed" up things are getting? Once you shift too far, things all sound basically like chipmunks.
The beauty of really slow shifts is apparent in spacey music. It has a gorgeous lush rising (or falling) sound.
A digital local osc would only make it better.

Why ?
If you make the oscillators digital (which is a good idea), you might as
well
replace the multipliers with multiplying DACs.

Calibrated V/Oct response adds one usefull application: Transposing the
shift oscillator in parallel with the VCOs (or whatever input sound). So
you can get the same (harmonic or non-harmonic) partials over the whole
keyboard range. Not a FS's most important function, but a nice one
nevertheless. See http://home.t-online.de/home/jhaible/hj_fs.html (#1).

Because THEN it's not an analog process. I could have gone full DSP and had
a CODEC and a DSP and that's about it, (which is something Chris and I were
discussing) but we wanted to retain that "analog" thang.

I would think this would be a very important part of a FS (if there is not an external input which would defeat the internal oscillator). I know that Mr. T. and I (as well as many others) on this list have had several discussions about the need for modules to generate complex non harmonic overtones for this very purpose.

RE: [motm] more NAMM poop

I am all for the digital oscillator if it will enable 1V/oct control. That feature is very useful for controlled harmonic, as opposed to inharmonic, generation.

I liked Jurgen’s suggestion about the multiplying DACs. After all, a DAC is just an R-2R ladder or binary weighted current sources, which is still analog in my book.

Encore Frequency Shifter (was: more NAMM poop)

I'm guessing that's .05Hz to 3.2kHz, or maybe my math is wrong?? Yes, that
is very difficult. The trouble is, motm users expect oscillators to have
1V/Oct control. It's one reason all of the other quality frequency
shifters out there cost over $1000.

That isn't true. In addition to what JH has already mentioned (getting the
amount of shift to track the keyboard), there are other applications that
depend on "tuning" the amount of shift.

>Once you shift too far, things all sound basically like chipmunks.

In that chipmunks are very quiet creatures and extremely large shifts would
render the output inaudible, this is true. If you are referring to Alvin,
Simon, and Theodore, that's pitch shifting using a tape machine -- an
entirely different effect :)

While there are frequency shifters that can shift by as much as 16kHz,
imho, that's far from practical, although I'm sure there are readers of the
Computer Music Journal who think it's a great idea :)

>The beauty of really slow shifts is apparent
>in spacey music. It has a gorgeous lush rising (or falling) sound.

Yes, low frequency shifts are required for "phasing effects" and feedback
control. When the amount of shift is a frequency in the audible range,
carrier rejection becomes very important.

While that certainly is a consideration, I like the idea of having
oscillator outputs. That way you get both a quadrature oscillator and
frequency shifter for your ~$400. They could be used as modulation or
audio sources with other modules. It also makes it easier to tune the
amount of shift when in its in the audio range. If the multipliers are
analogue, I'm thinking the oscillators could easily be tapped with dual
op-amp and two extra jacks. If space is an issue, TRS jacks could be used.

Also, wouldn't there be problems with aliasing?? Notice I'm not
anti-digital, I'm merely raising the question. A digital frequency shifter
might have its advantages.
