MOTM

All,

If you aren't interested in my ongoing modular sequencer project, 
read no further.

I've completely redesigned all but one Supermoe module. Changes 
include a radically different modularization of the address 
generation circuits, pulling the start/stop controls out of the clock 
(this influence from Peter Grenadier's Milton), and the addition of 
switchable musical interval timing ala the Roland Sequencer 700.

You'll notice that some of the modules now have jacks at the top - 
these reflect my latest thinking that I want to have a few of the 
live tweak-type modules close at hand in a smaller performance 
enclosure that contains a couple of joysticks and a ribbon 
controller. They will tilt back and patch cables will be out of the 
way going back to the main cabinet instead of tangling the joysticks.

I'm interested to hear what people think.

A very impressive design (again). I'm curious as to whether or not 
any of this has been breadboarded or run through a simulator?

Scott,

The only module that did NOT change (DAB-1084 pot matrix) has been 
running on breadboard for a long time. The only changes I'm making to 
it at the moment involve replacing the mediocre quality 74HCXX type 
analog multiplexers with some really nice Maxim parts. PCB design is 
progressing slowly as I concentrate on design of the address 
generators. I am slowly building a vector board version behind the 
actual front panel in the meantime.

Hi Moe, your modular sequencer keeps getting better with every 
revision.

Most of the Motm Cabinets that I have seen tend to be close 16 to 20 U
here are a couple of suggestions.

Since the DAB-1084 Control Voltage Generator is 8 U wide, I would 
believe most people would go for at least 2 of them. This brings the 
total to 16 U. If you put 2 of them in a row, you could use the row 
below it for Address Generation.

Now if arrange the DAB-1018 Address Generator Interface so that 
instead having in 2 rows in 7 U, you make it a single row so it 
becomes 14 U. This leaves plenty of room to put at least 2 of the DAB-
1044 Pulse/Gate Generators below. Above you would put DAB-1017 
Address Generator I/O. This would make for a more ergonomic and fluid 
design.

I know it makes for wide modules, but I think the ergonomics will be 
simple to follow. Just an idea. 

Once it gets to the pcb stage and boards will be available, will it 
be possible adapt the logic boards to other formats? or will the pots 
and switches be pc mounted for the Motm format only?

I think if you design the boards so the hardware (pots, switches, 
jacks etc.) is separate from the logic boards, it will help you to 
get people outside the Motm camp to adapt and build to the format of 
their choice. A lot of people in the Banana Serge and Modcan camps 
would like to have access to the functions of your uber sequencer.

Good luck,
RM

Hi Moe and all,

Have you seen this company or DIY person Analogic-acs?  Who are they?

http://www.analogic-acs.com/

Check out their huge synth with MOTM!

Since they are all about sequencing and control methods, it made me think 
about Supermoe.  How does their sequencing design compare to the Supermoe 
technique?  See their concept page--

What about their use of both bananas and 3/4 jacks?  Is there any advantage 
to that?

Hi Fred and all .
in the Analogic system we use banana jacks for the logic signals (gate or 
trigger) , banana jacks can be stack and act as mixr of logic signal  when 
many outputs are conected to the same input , or can act as distrebuture of 
logic signal from one output to many inputs .

this method enable to save logic mixers (OR gate) and multpile modules , 
this gives lots of freedome when creating a patch .
on the other hand precision cv  , or audio like in the MOTM is using shilded 
cable for best proformence as this signals are much more sensetive to cross 
talk and noise then logic signals , and also to make the cv out of the 
quantizer competable with the MOTM jacks .

Cheers
Gur Milstein
