Avoiding dips between patch changes

The dip, though be it minute, is audible. Am I right to assume that the ultra will never be able to remove this dip completely? I know the TC G major is "dipless".

If it's not possible, how do people switch "diplessly"? Double up? Kind of expensive alternative.

Thanks.
 
If you don't change your patch, but merge your two separate patches into a big one, have one half on and the other off and set it so that you can change what half is active with midi, the change will be instantaneous.

You can even blend the two halves with an expression pedal so that there is a smooth transition instead of an abrupt change.
 
Are you utilizing the spill over feature? You can have the reverb, delay or both spill over to fill in the void, which is what I suspect the TC is doing. It takes a few milliseconds for a new patch to load on any system.
 
G-Major 1/2 don't do amp modelling and 1000 things else that the Axe does. And G-Major is only gapless under certain conditions ... my G-Major 2 took a second for the Rotary effect to kick in (parallel routing) with a complete silent gap before that...

I never switch without holding back just a tiny bit (during the press of the switch), even with real amps. The Axe is fast enough (20 ms or so) to accomodate this.
Spillover can cover it up.

PS: With the MFC switching can be slower.

The dip affects the delay and reverb during spillover as well. I find the gap less noticable without spillover, even though I use spillover. The gap is short enough though. Zero would be nice if the layout is the same between presets, but I can't really complain about it as is.

that few!!! ??
I sometimes have 4+ in a song !! The "dip" is a matter of timing (it's millisecs) and setting up presets as per Yeks post.
Preset order/arrangement factors into the equation as well when using a foot controller. One should avoid bank switches in the same song.. 8)
 
Is there anything I can do to lower dip time? Is it a matter of CPU %? Or is it faster when one patch resembles the other? I originally thought that if I made two identical patches with "tweak" differences (panning, volumes etc), it wouldn't load it from scratch, but that's obviously not the case, right?
 
Higher CPU usage of the target preset (starting preset usage didn't matter) caused a slightly longer gap on average when I checked. It's always around 15-25 ms. How similar they were didn't make a difference.
 
I/O > Midi> Ignore redundant.....

This tells the Axe not to reload an entire preset if that preset is already active.
Useful when using a foot controller.

Let me make sure I understand this....ignore redundant means it doesn't reload blocks that are already active in the patch you're currently using?
 
If you have Ignore Redundant engaged, repeated presses of the same switch (re-triggering of the same MIDI PC#) will be ignored. Otherwise, every time your repeatedly depress the same switch, you'd get an interruption of the signal wile the blocks re-load. Ignore Redundant removes this problem, whether your "re-pressing" of the switch is intended or accidental. A necessary feature IMO.
 
I'll try that because I'm having the same issue and I use close to 30 different patches in a gig! I use 2 to 4 different patches per song, but they are similar so it might work!
 
Actually, meshuggah has a very interesting setup. When they're playing rhythm, they're on each other's ultras. When anyone switches to a lead patch, the other guy is switched to both the rhythm ultras, thus making panning a breeze! I'll explain it in more detail in case anyone's interested. Had a long chat with their guitar tech about this. Oh and the bass patch is the l6 agro running through a guitar XT pro!!!

Clawfinger (shares a studio with them) had a pretty detailed explanation of it in a post a while back.
 
A brief sound dropout is pretty much unavoidable when changing patches. The audio has to be muted during the switchover (otherwise you'd hear a harsh discontinuity as the patch changed). And if you mute and unmute too abruptly, you'll hear a pop generated by the muting itself. 20 ms is about the shortest dropout you can achieve without causing audible artifacts in the signal.

I tried to found that with the forum search and with "site:forum.fractalaudio.com clawfinger meshuggah" on google but I didn't get it.
Do you remeber something I could use to find Clawfinger's post?
