The Ould Sod Virtual Session

Please come join our weekly "Round the Circle" style virtual Zoom session every Tuesday night from 6:00 PM - 8:00 PM Pacific Time!

"The Ould Sod" is the San Diego neighborhood pub where, along with fiddler George Rubsamen, I've co-hosted a session every Tuesday night for over 20 years.

Of course, with COVID-19 precautions, sessions in person are on hold for the duration so we're all looking for other ways to have tunes together.

Because this session is on Zoom, please enjoy youself however works best for you!

You are welcome to volunteer start a set, play along muted the whole time, or just listen the whole night.


Here's How it Works


Anyone on the session may volunteer to start a set.

I mute everyone's microphones except the person playing the set.

The person plays their set, and everyone else can hear them and play along.

Because only one mike is un-muted, you hear only the person who started the set and yourself.

When done with the set, I will un-mute all the microphones (for those who have allowed the meeting host to un-mute).

At that point anyone can pick a new set to play and I do the same muting setup as before for the next set leader.

Recently, we've started adding some fun variations like "Celtic Karaoke" where players mix in recorded tunes from sessions or CDs along with their solo playing, and "Chained Sets" where we setup multiple players in advance to play a set of tunes in a specific style. As each player completes their one tune three times through, the next player unmutes and takes over with the next tune. This pattern then repeats for all the players involved.

Post-Pandemic Plans for this Session


On April 6, 2021, Governor Newsom announced that California will be ending essentially all COVID-19 related restrictions effective June 15th.

At that point, if not before then, with essentially all of our local players vaccinated, it may be possible that we will be able to restart our Tuesday night session at The Ould Sod Pub here in San Diego.

If that happens, I will continue to host the Zoom session, but will need to move the session to another night. There should be several weeks notice before there would be any changes.

Additionally, as more states open up, and more of us start playing sessions in person again, we'll just have to see how much demand there is for the Zoom sessions.

I absolutely intend to continue these events to stay in touch with all the players I've met from all over the world, but depending on interest, it may become a monthly instead of weekly event.

Again, nothing will change for at least the next month or so, and I promise to keep you informed of any changes well in advance.


Zoom Mute/Unmute Permissions


During the session, I mute all the participants other than the one person playing at the start of a set. When they have completed their set, I un-mute everyone at once.

As a result, if you have not specifically opted-out of letting me unmute you, your microphone will be live when I unmute everyone.

If you always want to remain muted, please check out this Zoom support article on setting unmute permissions:

Best Audio Settings for Zoom


For best sound on Zoom, either on a desktop or mobile device there are two audio settings you need to change for best sound when playing music:

On the desktop clients, you MUST set "Suppress background noise" to "Low".

Generally it's best to leave "Echo Cancellation" enabled.

On the mobile clients, turn on "Enable Original Sound", found under the "More" menu while in a meeting.

Zoom audio settings

You must select "Show in-meeting option to "Enable Original Sound" from microphone" in order to see the Music and Professional sound options. Set the Music and Professional sound options as best matches your setup.

If you disable echo cancellation, you will need to wear headphones when using Zoom. Also, when using these higher quality settings, Zoom advises connecting to your network via Ethernet instead of WiFi for best performance.

In the meeting settings turn on "Use Original Sound" and in the meeting itself, turn on "Enable Original Sound"

iOS versions of Zoom now support the "Use Original Sound" option to improve sound for music. This turns off the background noise suppression that often causes instruments to get cut off on sustained notes.

You have to turn it on in both your meeting settings as well as when on a Zoom meeting.

In the meeting settings turn on "Use Original Sound" and in the meeting itself, turn on "Enable Original Sound"

iPad-Based Zoom Audio Appliance


I've recently put together a standalone iPad-based voice and instrumental audio pre-processing system for use with Zoom meetings and other online broadcast platforms. 

I've received some good reviews from others on the quality of the sound produced, so I'm sharing the setup.

The system is designed to plug into the audio input of a computer running Zoom to provide superior audio quality than a microphone alone and has nearly infinite flexibility.  

This iPad-based setup gives me much more flexibility and control of my sound processing during live streaming than my previous analog setup ever could. It will even run on older iPads. I am using an iPad Air from 2013 running iOS 12.4.5.

The setup consists of a Shure MV-88+ microphone, microphone stand, an iPad (attached to the stand using an IK Multimedia iKlip 2), and an Apple Lightning to USB-3 Camera Adapter. 

The Shure MV-88+ could be connected directly to the iPad via the provided Micro USB to Lightning cable, but the audio processing software would drain the iPad in about an hour. Since I'm typically using the setup for two to three hours continuously I needed a way to both hook up the microphone and power the iPad at the same time.  

To solve this problem, I connect the MV-88+ using a Micro USB to USB cable to an Apple USB3 to Lightning adapter plugged into the iPad. I can then plug a standard Apple charging cable into the Lightning port on the adapter. This allows me to power the iPad while using the microphone. 

To use the MV-88+ via USB like this rather than directly connected to the iPad via the Shure provided Micro USB to Lightning cable, you first must connect the microphone directly to the iPad with the provided micro-USB to Lightning cable, run the free Shure Motiv App, and configure the microphone level and pickup pattern.  This is only required to be done one time.

I initially selected the single front facing cardioid pattern option, but further experimentation had me switching instead to the 60-degree (narrowest available) stereo option for better background noise isolation. Both are good options. I set the microphone sensitivity in the Motive app so that on whistle I'm at nearly max level, but not overloading the microphone. You will also want to turn off any compression or EQ enabled in the Shure Motive app. Once you've done this, the MV-88+ stores the configuration and you can then use the microphone over USB for other apps.

Any other high-quality USB microphone would also probably work with a similar configuration.

To get the sound out of the setup and into Zoom, I run a stereo 1/8″ cable from the iPad headphone output jack runs into a input channel on my mixing board, and then from the board into the input of the audio card in the Windows computer I use which is running Zoom. The mixing board board allows me to set various levels into Zoom as well as control my own monitor levels in the headphones. If you don't have a mixing board, you could just run the output of the iPad headphone jack directly into the audio line-in on your Mac or Windows computer.

The iPad is running AudioBus as a plug-in container app, and the following AudioBus compatible plug-ins in a chain:

AUFX:Push - Compression - Limits and stabilizes the dynamic range particularly when I'm playing louder instruments like whistles.

AUFX:PeakQ - EQ - Allows me to do some voice equalization for that "NPR" radio announcer sound.

AUFX:Space - Reverb - A tiny bit of added room ambience is more comfortable both for me in the headphones and for other people in the Zoom meeting.

Below are screen shots for the setup of AudioBus and each of the AUFX plug-ins:

AudioBus Settings for lowest latency
AUFX:Push Compressor Settings
AUFX:PEAKQ Equalizer Settings

If the 9.2 db "Peak 1 Gain" boost is excessively boomy, try lowering the value to 6 db or even 3 db.

AUFX:Space Reverb Settings

Additionally, if you need background noise reduction, for example from an air conditioner, and want something more subtle than the hard noise gate in AUFX:Push, I've had some success with putting an instance of Audio Expander AUv3 at the very front of the plug-in chain for use as a downward-expander. A downward-expander does the opposite of a compressor, it takes any sounds below a certain loudness threshold and reduces them by a controllable ratio while passing through all sound above the threshold. It provides a much more comfortable sounding transitions when speaking or playing than using a hard noise gate under the same background noise conditions. Note that this doesn't eliminate the background noise while you are talking or playing, but can quiet it significantly in a controllable fashion during periods of silence. You will need to tailor the threshold and expansion shape settings for your specific situation:

Focusrite Scarlett 2i2 Integration - August 5, 2020


I'm trying out the next incremental evolution of my Zoom online session hosting audio setup.

Now using a Crown CM-310A Differoid condenser microphone connected to a Focusrite Scarlett 2i2 USB preamp/interface and from there to my iPad Audiobus-based streaming audio processor (downward expansion, compression, EQ, reverb) via a Apple USB3 Camera adapter.

The adapter also powers the iPad from a power adapter.

Stereo output of the Scarlett (previously was the iPad headphone out) is then connected to the Mackie mixer and from there to a dedicated M-Audio Audiophile 24/96 audio card in my Windows computer and into Zoom.

The Scarlett 2i2 does require a powered USB hub to use with the iPad.

The Shure MV-88+ USB microphone that I was previously using is awesome, and in many ways more convenient, but the Crown CM-310A mike has some real advantages. For example, I can leave my A/C on in my office while on long Zoom sessions since the CM-310A is both sensitive and very directional and also has built-in background noise canceling features.

The pop filter also helps with voice and whistle plosive noises.


Dual Channel Focusrite Scarlett 2i2 - 7 August 2020


Update February 2021:

Since this photo, I've replaced the Crown CM-310A voice microphone I was using as an instrument microphone with a large-diaphragm Audio-Technica AT3035 condenser.

The AT3035 is much more sensitive and able to pick up both sides of a concertina or accordion, or both the chanter and drones/regulators on my pipes. I continue to use the Crown CM-310A as my voice/whistle microphone, but now with a smaller pop filter.

Here's my latest Audiobus setup for a dual input system that has one processing chain for my voice/whistle microphone, and another for the pipes/accordion microphone:

Things are now getting freaky. 🙂

The Voice/Whistle microphone chain:

ExpanderFX - Downward expander for optional A/C background noise supression

AUFX:Push - Compression

AUFX:PeakQ - Equalization (primarily for voice)

AUFX:Space - Reverb

The Pipes/Accordion microphone chain:

ExpanderFX - Downward expander for optional A/C background noise supression

RoughRider3 - Compression

Zero Reverb - Reverb

Unfortunately, I can't share the AUFX effects between the two input channels from the Scarlett 2i2 as they are single instance apps, not Audio Unit 3 (AU3) plugins. So, to work around this, I had to use a different compressor and reverb plug-in for the Pipes/Accordion chain.

Here's the Audiobus mixer view of the setup:

In this configuration, the workload was taxing the CPU resulting in occasional pops/clicks, so I had to dial back the latency settings from 64 frames@48KHz to 128 frames@44.1KHz:

Here's the apps I use as they would appear on the iPad's desktop. Audiobus 3 is in the dock in this screenshot:
