Topic: Feature request Delay for UFX

Feature request:
On each input, provide a delay that is adjustable from .01 msec to 500 msec.

I can think of three uses:
1. time-alignment of spot microphones when mixing live acoustic music ensembles such as orchestra, choir, soloists.
2. reducing phase anomalies in drum mics, etc.
2. delay signal to rear speakers in a live sound reinforcement system; particularly for smaller touring rigs where amps & speakers may not have any delay capability.

Re: Feature request Delay for UFX

Channel delay can indeed be useful for on-the-spot mixes, however you might need to re-consider your specs.

0.01msec - that's half a sample at 44K1, not sure how you do that.

30 inputs, 0.5 sec at 192K needs about 12MB memory - not sure how much is spare inside the UFX.

Feeding delay towers - wouldn't you need that on the output rather than the input?

For the first two applications, a minimum of 1msec (anything smaller try moving the mic slightly) and a maximum of 50 msec (maybe 63 msec) seems to cover most on-the-spot requirements.  And would require about 1.5MB of buffer - less at lower sample rates, and of course not all inputs would be using maximum delay.

Maybe someone could indicate if this is on the roadmap for TMFX?

< 1 msec settings are for adjusting phase relationships that affect tone, but only in post production. Many things prevent me from making small physical mic adjustments when capturing live acoustic performances. I get this from Cubase and it would be nice to get it from TotalMix.

500 msecs would be for speaker delay in outdoor venues. One could make an argument for even longer delay, but then you'd probably be in big spaces and have software controlled tower arrays.

Re: Feature request Delay for UFX

We denied this request before, in this forum, at least two times. Apart from that there is no memory in the unit, the more you ask what it is good for the more comes out that it is either not really needed, or just to replace something already existing. That's more than one reason to work on other, more useful features.

Re: Feature request Delay for UFX

It's certainly no deal breaker. The unit is working superbly and I love how it sounds.
