Analogue-sequencer

hi all...

so, this weekend i made my first baby steps into aux-land... but what i
attempted did not work. so i'm asking those of you who are more
experienced in such things...

i have one pattern of tbase 8 that has four notes. i want the last two
notes to be transposed by -4 and -3 semitones, respectively, every other
repetition of the pattern. (i know the easy way is to use a pattern chain,
but i'm learning here!) so here is what i've done:

Accumulator D config: range = 1, mode = return-to-zero

Aux A = set aux d rel +1 (last step of the pattern)
Aux B = set note rel -4, -3 (on the two notes that i want transposed)
Aux C = mask aux b when acc. D > 0

what i think should happen is that the first time through, aux c should
mask aux b because the acc. d value is zero. at the end of the pattern,
the acc. d value will be incremented to +1. so the second time through,
aux b should have an effect. then when acc. d is incremented to +2, it
will exceed the range and return to zero, thus masking aux b on the next
repetition, etc.

what is happening is nothing. :) i guess that means the masking is
working, but something with the accumlator is not? or do i have to mess
around with the note accumulator settings too? i don't think i touched
those at all... i figured that tweaking them relatively made it
unnecessary for me to do that...

thanks for any help...
fred.

bleep.
out.

I think you're missing the essence of the accumulators.
The accumulators are 'running totals' that get added to their targets
(note, velo or aux D) on every step - unless you use 'acc defeat' or Xd
on note steps.
When a new pattern is selected, the accumulators are set to 0.
So every note sent will be (note value) + 0.
When you use 'offset note rel' with a value of -4 the accumulator will
decrease by 4.
So every step after the first offset will send (note value) - 4.
The next step having 'offset note rel' = -3 will set the accumulator to
-7 i.e. the offset value 'accumulates'.
Steps without a relative offset of the accumulator will still be
transposed.
You just want to use an 'abs' offset on the two notes to be affected,
but you'll need to set the accumulator back to 0 on the first step,
otherwise the offset of -3 will continue to apply.

The next point is that the auxes are processed in alphabetical order.
So if you are going to mask an aux, it must be masked by an aux *before*
it.
Otherwise the aux you want to mask will already have been processed by
the time it's masked.

So what you want to do is use 'offset note abs' with values of -4 and -3
on the last two steps, and also have an 'offset note abs' = 0 on the
first step (to clear the accumulator value set on the last step).
Without any masking, this will leave the first two steps un-transposed,
but transpose by -4 and -3 on the last two.
Use aux C for the 'offset note abs' event (so we can mask it), and make
sure the note accumulator config limit is at least 4.
Use aux A for 'offset xD rel', with the value of +1 on the last step
just as you did. Use aux B to mask aux C - but only on the last two
steps, otherwise your accumulator wont be reset on the first step.
Your aux D config was right - limit of 1, with rtz.
Hope that helps...

Also worth considering the "Set Note" aux.

ahh... that helps... i thought it was something... that apparently it's
not, heh. :)

i played with the abs offset for a bit and was mystified that everything
got transposed down every repeat... sounded pretty cool tho. for some
reason, i thought that acc. values reset at the beginning of each gbar...

i wondered if that weren't the case... i'm not sure it says that in the
manual... i tried to look for something like that.

it does... very much so... thanks!

That would be 'rel' offset that was transposing down every repeat...
'Abs' sets the accumulator to an absolute value. 'Rel' sets the value
relative to its current value.

It should be in the manual... But the auxes really need a separate
tutorial.
We were intending to do something along those lines at the weekend - I
was down at Paul N's on Saturday.
But we got "side tracked". 8-)

maybe my P3 got "side tracked" too... :)
