Arp Legato Bug?

Elektron Gear Analog Keys/Four
#1

When I turn the arp’s legato setting on, the volume drops to nothing after a second or so.

I tried setting the release of the amp envelope to infinite, and that gave me a very faint signal, but it’s not functioning as I expected it to.
Adjusting other amp envelope parameters or the arp note length doesn’t seem help either.

Checked the manual, and it wasn’t helpful.

I did a search, and unless I’m misunderstanding the way arp legato is supposed to function, it seems to be an old bug without a solution.

Anybody have any ideas?

The note triggers themselves need to be long enough, otherwise the sound just fades out.

Thanks for the reply.
I’ve got a sequence with a 64-step-long trig that’s a chord which arpeggiates fine through all 64 steps when arp legato is set to off.
As soon as I turn on legato on the arp page, it dies after about a second.
Changing the note length on the arp page or the amp envelope release to infinite seems to allow the notes to continue to play, but it looks like neither of the envelopes are firing as the notes change…
I guess that was the problem all along.
Any idea how to get the arp to retrigger the envelopes in legato mode? (That trig I set has both envelopes switched on on the note page.)

LEGATO = ENV’s don’t retriggger… if I’m right…

As vos said, I think you’re on a different page !
.
The reason your ARP is fading is due to the AMP envelope - also look at the Len parameter for Note - the amp envelope profile for the sound triggered once with the ARP off will superimpose - also look at the ARP len too
.
You can vary the blurring between notes when the Legato mode is on by changing the Slide value on the sub page for OSC2

I’ve been playing around with this on and off for a couple of days, and the problem seems to be what vos said there- the envelopes don’t retrigger in arp legato mode.

Adjusting the amp release or arp note length to infinite does keep the notes from dying out, but I realize now that without any of the envelopes retriggering, I won’t be able to produce the sound I’m after.

I’m sure I could add in trigless locks to trigger the envelopes, but then they wouldn’t be synchronized with the arp speed. I don’t know why the arp triggers the envelopes normally until it’s legato mode is activated, but that seems to be the case.

Bummer.

what do you think Legato mode is out of curiosity ? ie why turn it on when it does what you ask for when it’s off

Avatronica, I’m after the pitch slewing.
Is that technically called portamento? I don’t really know the difference, and they often appear together.

I have to say I also don’t understand the Arp Legato.

When I turn on Arp Leg and have a, say, 15-step trig with 4 notes on step number 1, I cannot get the arp to sound longer than 3 notes… No matter how long i set my Amp Dec(ay).

Curiously, the duration of audible notes does not stay the same when I change the arp speed. Rather, the duration decreases. So it looks like the number of notes plaid in Arp Leg mode is limited…

What would be really helpful is if someone posted how to:
Get a 16-step arp line with Legato on that slowly fades in volume (or has its cutoff decrease via ENV slowly).

Sammelkom, try increasing note length via the note page to get more notes in your arp.

I can’t figure out legato either, would have expected it to slide between notes when on, seems to do nothing. Legato pros, we needyour knowledge!

#11

Yeah, but as I said, I have a trig with note length=15

#12

The way I understand Legato is that a note - attack fase isn’t retriggered. so all depends on the note length - and envelope-lenghts of the first trig.
Nothing to do with sliding - Glissando .

Dredging up an old thread, but I think OP is right about there being a bug?

Just got my A4mkii, was playing around with arp legato, and unless I set the arp len parameter to a huge (or inf) number, it cuts off after one or two notes of the arp. (it’s unpredictable, like at arp speed 3 it plays one note; at a slower arp speed 5, it did 2 notes)

Note length is much longer than the arp speed (speed 2 or 3, note length 8). Amp envelope is a full-sustain envelope, so it’s not that.

#14

But what’s the decay ? The second ARP note may be forcing the decay stage (don’t get drawn into ARP len vals too much presently)

Tbh, I’ve observed oddness, whereby e.g. the perceived length of (at that stage) abruptly cutting audio was much longer when the ARP speed went from 8 to 9 to 10 (i.e. it was longer at 9, but abrupt at 8 and 10 - hard to account for this)

However, having just wiped the pattern and sound and started from scratch it seemed fine

Clear Pattern / Clear Sound

Set ARP Mode to Tru / play&hold mini keys = all good

Set Legato on / play&hold mini keys = 2 notes (at default decay)

Try dialing up a longer AMP decay = what you want

Have a look here for Len(arp) chat

Also - keep an eye on filter env too - it may also be obscured if you kill the filter env lifting the sound (by going legato) - so keep an audible filter value irrespective of its env when testing this out
