Analogue-sequencer

Hi there,

I have some questions about the AUX Events.

1. Accumulator (e.g. Velocity Accumulator)
Is this a value, that is held in one variable per Track, and to which
I can add or subtract values, and then this new value will be added to
the Velocity-Values that I set up for each step? What happens if the
accumulator reaches a value of 127 and beyond? It goes back to 0? I
guess so, and so the "offset rel" Events make sense to me. But for
what can I use the "offset abs" events?

2. Randomize Velo
Here a random value between 0 and the AUX Value is added to the
Velocity Values, right? But what happens if this is more then 127? So
e.g. the Velo is 120 and the Random Value ist 20, then would the
result be 13? For the Accumulators, it makes sense to me, but for the
Random-Aux-Events, I would prefer the Values that are "higher" than
127 to stay at 127, so 120 + 20 = 127.

3. AUX D Accumulator
Here I have an Accumulator for AUX Events? I'm not quite sure if this
is right:
I set AUX C to "offset AUX D rel" and have on step1 a value of 1.
I set AUX D to "Randomize Velo", and have all steps set to 1. 
And then with every cycle the Range of the Random Velocitys goes up by
1, because the AUX D Accumulator is counting up?

I'm just starting to explore the AUX Events, and couldn't manage to
create simple examples, that make this things really clear to me. So
please tell me if I'm right or wrong with this. Or maybe someone could
make a simple tutorial, like set AUX C to this and step 3 to this and
then happens this, bla, bla. 

Thanks in advance,
Stoffel

That's exactly what it does.
"Offset abs" just sets the accumulator to a specific value.
I haven't used it much, so maybe it's superfluous.

It does make sense the velocity should be limited to 127.
I just haven't got round to fixing it yet. It'll be in the next release.

That's exactly right.
Sorry I haven't got round to updating the manual with aux events yet.
But it could still take me a while, as I'm chronically busy, and it's
going to be a hard part to write clearly too.
There is a bit more work to be done on the accumulators themselves too.
I'm planning to allow you to set limits, and a choice of
wrap/rebound/clip behaviour for when they reach the limit.
This should allow LFO type effects. One day...

Me neither - athough I could see a value in it if you either swapped
it with another track or used another event to turn it on or off. That
way you could toggle between two known values using whatever criteria
you happend to be be into.

Of course you can make it behave like a rel by using an abs on AuxD
and incrementing that from another aux <g>

Heys, 

Ive been toiling for the past couple of days on a new enclosure for my doepfer / analogue solutions modular.

The plan is to run the setup (12 x 86hp of modules) from a coupe of sealed lead acid batteries when on the move with it.

Now when the new run of p3s come through, im thinking a p3 would make a pretty complimentary addition to this setup.

Paul / Tony's poly dac will, it seems, run from a +/- 12v bus, so that part of it taken care of, but then on to the p3...

Now its late here, and i haven't looked at all of the schematics, but from my brief look, it appears that the 9v (or whatever) supply is regulated down to 5v.  Regulating a 12v supply from a SLA battery will, if im not mistaken, be a reasonably inefficient way of doing things.

Im wondering quite how bad the situation would be.  I was looking at a couple of 7.2ah batteries for the synth, and its probably about an amp of drain.  Providing the synth works out ok, what would be my best plan regarding the p3?


cheers, julian

(incidentally, the p3s din sync will be put to good use feeding into my battery powered, modded tr606 for a nice little self contained portable setup...)

Another good use for abs events I thought of whilst out on my morning
walk...

Really applies best to abs note transpose events. I was wondering why
they might be cool - and then realised they can be used to create two
sequences within one with the Aux activation events used to toggle or
morph between the two sequences. You could even use mask/probability
type factors to gradually change from one to another without the
unpredictability of rel changes.

It's often good to have things in there for which there is no apparent
use. Someone will always find one... 8)
