Analogue-sequencer

Hi;

I got an serial 7*** minimoog wich came with cv in.. Every time I connected it to an analogue
sequencer sounded very strange.. Now I have turned it on after 3 years off..

And with a kenton pro 4 .. still sounding " strange" as monotriggered envelopes or non tracking filter ( I knew something about that)..

So it is not possible to have a proper sounding sequenced mini?

By the way,to have " slide" Do I have to plug cv into portamento in?

I have listened to mini basslines from the 70´s with cool manual portamento..( Barry White) just figuring how to do that with a sequenced mini.

Thanks;

Hans

The minimoog's CV in facilities are not what you might expect - no filter
tracking, and the glide circuit is in the keyboard, so it doesn't affect
note CV. There's a mod on the web for adding filter tracking:
http://analog.no/mods/moog_minimoog_cv.htm
I would have thought there was a slide option in the Pro 4 that you could
set up.

I have a home built CV convertor on my minimoog, with an auto-glide circuit,
and a CV mixer for routing note and velocity CV to the filter CV input.
That's a better approach if you want to leave your minimoog unmodified.

Hi;

And that mod affects is simple to do?  Do you recommed it to me?

If not, my signed personally to me by Bob is just a decorative item?

But.. How did others sequence the Mini back in the time? 

Best

Hi,
Now we're on the Mini CV subject.
I'm planning to do that filter CV-follow mod. I really miss filter tracking when controlling the mini from the P3. Osc-sync is another mod which I'm thinking about...(!)

Now I have a question about the glide. I know most midi-cv converters offer glide but I really prefer to do it on the synth (like on the SH-101). That way you can tweak it live, more hands on :-)
Am I correct that the glide circuit is a seperate circuit, it's just a lag processor isn't it? Could it be possible to let the external CV go through the glide circuit??
Did you ever think about it to do it this way Collin? It seems that you've studied the Mini schematics before... Do you have time to look into it?? It seems to me that you actually know how to read schematics :-). It would be nice to know where to insert the CV -before- the glide circuit..
Sorry for asking... but you're probably the best person to ask.
Cheers,
Eric

My personal choice is to use an external circuit to give fully variable
filter tracking (not just off, 1/3, 2/3, full).
The mod I linked to is non-destructive, so you can reverse it, and it does
keep things simpler.
I chose not to mod my minimoog at all internally, since it is a very early,
all discrete unit.

Back in the time, I think they played them by hand ;-)

Osc sync is nice, but IMO you really need envelope modulation of the synced
oscillator to get the best out of it.

My convertor has a knob to control glide time, with the added advantage that
glide is generated digitally, so the time can be over-ridden by a MIDI CC.
I can assign an aux to set glide time per step in a P3 pattern.

Glide on the mini is part of the keyboard circuit, which makes it less than
ideal to hack into.
I'd really recommend using an external glide circuit. Aside from anything
else, it's very useful to have a choice of constant rate or constant time
glide.
You can still tweak it live if you keep the knob handy, like this...

And of course Colin already made a nice little box for it :-) Nice Mini btw!
Sync indeed gets more interesting when the slave Osc is modulated but I feel that would be to much modding/adding switches/pots to the Mini. I read somewhere that someone did it by installing a push/pull switch-pot for the tuning knobs (sync on/off). That must be a nice and aesthetically correct solution.
Osc sync on the Moog Prodigy sounds very nice!
Indeed it would be nice if the keyboard tracking was fully variable... and if one could control the filter with velocity...and that with a pot.. Your little box looks really handy to me. If possible I'd like one! Or better, the populated pcb so I can build it into some wooden housing with Moog-like knobs :-)
Maybe it's better to bother you with it off list. 
Cheers,
Eric
