Title: Gated Sequencer destination list
Post by: chapelier fou on July 26, 2018, 05:00:46 AM
Hi there, I just received my Prophet Rev-2. But I also own an OB-6, a Pro-One and a DrumTraks.
So hello !  :)

I am trying to route a Gated Seq track to the amplifier envelope's Attack. So I select "Env VCA" as destination. I can't hear any effect. "VCA Att" produces no effect either. Is this a bug, can someone confirm please ?

BTW, I find some of the destination names confusing. Anywhere to find their signification ?

I actually never tried the sequencer to modulate the amp attack, but normally the destination should be "vca att".
Then, enter your sequence steps: high values for steps with slow attack, low values for steps with quick attack.

2 things to take into acount:
- all modulation sources "add up" and "can't exceed 100%". Meaning, if you already had the vca attack programmed to high value (slow attack), the sequencer will not have a lot of effect to add (can only make it slower up to the max value)
- if your program has a slow release (high value for VCA release), the vca does not have the time to close substantially after each step. And because it retriggers from the value it is at, you will not hear a lot of change.

So to hear the full effect: program you patch with amp attack at zero and amp release at zero, then program your sequence

Thanks for the reply.
Actually, I think this is really a bug. It doesn't make any effect, or worse, it produces the opposite effect.
Take a sound, with 0 Attack and 0 Release.
Select "VCA Att" as destination for the sequencer track. Enter a high value for step one. Select a very slow clock. You'll hear it has no effect.
But worse : then, manually change the Attack to a big value. Now when the sequencer reaches step one, it should produce a very long (maximum) attack. Result is the opposite. For this step, Attack will sound as 0.
Is there any changelogs for the firmware updates ?

I've tried it. The higher the value in the step the faster the attack.

So it would be inverted, isn't it ? I guess you're right. If in the contrary I set my Amp Attck to the full value, I can make it shorter with the sequencer.
It seems that it subtracts the value to the knob value instead of the contrary. So, according to me, this is a bug. It should be the other way, shouldn't it ?

Tried it last night on my mopho (don't have a rev 2 (yet)), and indeed, same inverted behavior as you describe. So at least it is not a new bug, I run an old OS on my mopho keyboard.
At least you know the solution now, and if it really bothers you, you can always invert the sequencer which makes it work the way you want (but of course sacrificing a mod slot).

I don't know whether it is a bug. The behavior is not listed in the manual so it may be by design.

ha ! use a Mod to invert the sequencer output, that's a clever idea !
