Dual VCO attack time

The sounds you can get from the dual VCO engine never cease to amaze me. However, I often struggle with getting the timing just right, as there seems to be rather elongated attack phase on the sound, irregardless of the settings on the amp page.

I’m currently playing around with a sound and have the attack set to 0 on the amp page (no filter envelope or LFO set up), yet when I have the sound triggering perfectly on grid, it’s just slightly behind everything else in the pattern. If I try to move the trig forward with micro-timing, it can sound slightly better, but still not really usable.

I recorded some audio from this track into Ableton and the audio clip waveform did show a very gradual attack at the start of the sound. However, I wasn’t worried because I knew there were 75 other VCO configs to try and assumed another waveform would do the trick.

Unfortunately I’ve tried all of the different VCO configs but to my ears all of them have a very distinct swell at the start of the sound. Even the ones with identical waveforms on each sound seem to have an initial movement/wobble/swell at the start which is putting it out of whack with the other elements in my project (and even the click track!!!)

The dual VCOs get a lot of love on here. Can anyone help me out?

Did you perform it on the pads? Velocity and aftertouch could be interfering, but I dunno why they would be, but it’s worth checking.

No, I just entered the notes on the sequencer in the conventional fashion. Its interesting you say that though, because it does sound a bit like that. It almost sounds like that swell you get with aftertouch, but much more subtle and very quick, right at the start of the sound.

That’s what I’m getting. Very strange. Unless it’s completely normal?

This was recorded when I had an LFO on the track, hence the movement in the waveform for the rest of the sound, but even without the LFO the results are the same.

Do you have the bend knob active at all on the DVCO? It looks like there’s a pitch envelope of some kind on that.
Make sure your amp envelope isn’t doing something strange too but this definitely looks like a pitch thing.
Does it happen everytime you trig it or just the very first one?

Agreed. Looks like bend is active

BEND!!!

Well, kind of anyway.

Bend was actually set to 0 but I noticed that changing the value made no difference to the sound whatsoever. Turns out I had bend being modulated quite aggressively by the velocity modulation. I have no recollection of ever setting anything up with velocity modulation in my life, but there you go.

Another mystery solved. Thanks one and all.
