Phase on overheads and room mics??

[BloodPremonitions]

Hi there,

When I am ‘solo’ing either room microphones or overheads, I hear a lot of phase/comb filtering on them? I mean it is a serious, ridiculous amount. How can I address this? I have no idea how to remove this in SD3?

The issue is quite severe, if I add a compressor to the OH or room mics, it’s completely unusable? Is there a section in SD3 where I can check the phase?

Thank you.

Need more specifics. Which channels in particular? Some of them aren’t meant to be used in tandem.

Do you also have the phase button on?

Thank you for your answer.

The channels with phase on them are overheads and an ambient room mic.

 

[BloodPremonitions]

The phase is still on the overheads regardless of whether the button on the channel is turned on or off.

 

[Bear-Faced Cow]

Which channels specifically and which library? There are some libraries that have more than one type of mic on those channels.

Also, what instrument is phasing? Are we talking about drum hits or are the cymbals “phasing” because they are physically moving after being hit?

I am using SD3 standard, no expansions.

The two channels that have phase are dynamic overheads and ambient ribbon. And when I say phase, it is really quite extreme.

My set up is also very simple: 1 kick drum and two floor toms.

[BloodPremonitions]

The room microphones and ambient ribbon microphones are phasing everything that is being sent to that channel: so the two floor toms just have absolute piles of phasing on them, particularly on the tail. :/

No cymbals either?I really don’t understand how the ribbon mic could have phase on it if I’m just solo’ing that channel?

I’m very sorry about all of the flood of messages here however I have discovered that it is indeed the toms that are phasing. But they only cause phase when the two floor toms are both played at the same time. If they are played individually, then there isn’t any phase occurring in the overheads :/

Again, I’m not using ANY eq, compression or time based FX and have the single overhead ribbon microphone on solo mode.

Any idea what this could be? The toms are designed to be exact replicas of each other… Could it be possible that since they’re making the same kind of wave form that this is where the phase is occurring?

Are both toms playing the exact same MIDI? Phasing could be that the round robin sample picking is different for each and sounds like phasing.

thank you for your answer.

 

There are two tons routed to different channels, I one left and the other right. On the grid editor when they are “played” at the same time, I get this phase sound. Does this sound like it could still be playing the same MIDI?

I don’t know. Are you sending or playing the same MIDI through both toms at the same time?

You say “played at the same time” which seems to indicate yes, you are sending the same MIDI to both toms at the same time.

I just did a test with two floor toms as described above playing the exact same velocity on the grid. There was zero phase/comb filtering on the ambient ribbon or OH both solo or in combination. I also tested with a couple of the clean kit defaults. Same result.

So I tried to start the set up from scratch to just in case I had missed something or unwittingly hit a parameter that I was unaware of. I removed and replaced the instruments, completely unedited and I always get phase if I load two floor toms that are twinned 16×18  floor toms by pearl masterworks. However, if I load a different floor tom, there is no phase/comb filtering? Weird that I can’t match these two floor toms together? I should reiterate that it isn’t a mild amount of phase, either, you can hear it completely clean already but any kind of compression applied renders the set up unusable which is disappointing as otherwise it sounds quite pleasing to my ears.

Surely there must be others out there who have loaded these two floor toms together and have had the same issue?

Thank you for your assistance. I appreciate the community in the forums here and the willingness to take the time help.

So the two toms are programmed to strike at the same time in the grid editor however both floor toms have their own separate grid and are marked as ‘floor Tom left” and ‘floor tom right’. The channels for both of these floor toms are separated, the microphone they are sharing is the overheads and there is only this phasing effect when then the grid is programmed for them to strike together at high velocity.

If I switch to any other floor tomorrow, this doesn’t occur.

[Bear-Faced Cow]

Like I said, I didn’t experience any phase or comb filtering issues on the OH or Ambient Ribbon channel. Post a Superior Drummer project so we can see what you are doing. something is not right.
