SoundBrenner Pulse wearable metronome, first impressions

What people say

This product appears everywhere in timelines on social media when you’re interested in making music. I must say it immediately got my attention when I saw it. For me the appeal is that would solve the problems playing along with the computer when practicing or playing live. I don’t always have live musicians to play along with and the computer is unforgiving. Any metronome is welcome there and the SoundBrenner Metronome app is then already of great help.

But now the Pulse is there and it adds to this a haptic vibrating metronome you can feel. Now you don’t have to look at blinking lights while playing.¬†Also, I use Ableton Live, also live, and there is even the possibility to use Ableton Link with Metronome app. If this all works together as one integrated haptic Metronome that allows me to feel the tempo while playing along with Ableton? Perfection! The ultimate gadget heaven!

Before buying I always look around for reviews and more info. One big complaint is that it is not an actual watch kind of thing. A lot of people hoped that it would also display the tempo. It doesn’t. You have to look at the screen of your phone (or tablet) to see settings and tempo. This also means that you have to keep the phone screen on. At the same time the Pulse is connected via Bluetooth. The phone is the brains, so you must at all times keep it charged and connected. A challenge, specially live.

Then there is some word going around on it not being accurate, but I think that is already fixed now through firmware updates. Another complaint is that it takes time to get used to ‘feeling’ the tempo. I guess that a lot of people send it back immediately, but I am more patient. Most new skills take time to get used to and I am quite convinced that this Pulse is a good idea. But now for first impressions.

What I say now

When you first start using the Pulse you will find that it is a bit fiddly to operate. You have to tap the watch face to start using it, but its not really touch sensitive. You have to really press it to pick up the taps. Then, straight out of the box it is set to really buzz the rhythm very strongly. And audibly also. Fortunately you can immediately go back to the app to set it to a more friendly and short vibration. In the lightest mode it really feels okay, but I play keyboards, When playing a more physical instrument, like drums, I can imagine you need the stronger buzz.

Charging it is also fiddly. It is a small kind of dock that has to properly connect to the device. After popping the Pulse in the band it gets even harder to let it connect to the charging dock, because the band pushes it from the dock and the dock can easily slip away, because its so light. People complain about the time that the device can be used on a full charge, but I don’t have enough experience now to say if it is really a problem for me.

Then its time to start practicing and linking it up with Ableton Link. That’s where all starts to get a little bit flakey for now. Ableton Link somehow goes in and out of the connection with the app. Which is ok for practicing in my case, but I don’t think this is ready for playing live. Also my phone sometimes loses connection with the Pulse after several minutes of playing. My phone is an Android phone, running Oreo and I know it can be very aggressive in killing background processes, specifically if they draw power. Probably that is not helping here, so I want to try it with another iOS device also.

One other thing to mention: its quite a big device. Maybe better suited for male wrists. There is another bigger strap in the box for your leg or your upper arm, but this device will have a hard time looking elegant on fragile ladies arms.

First conclusions now:

  • Big. Don’t expect this device to be light to operate, you really have to tap hard
  • Dive in to the settings to tune it to your preferences
  • Great for practicing, but for playing live this is a really complex setup to get and keep running

I hope this helps you appreciating the device for what it is now. I will keep using it and I’ll keep you up to date. Please note that there is also a new Soundbrenner device on Kickstarter that is actually more like watch, the Core.

Editing a music video for IGTV

From lying down to upright

Instagram took everyone by surprise by introducing the new upright video format IGTV video channel for all users. Shooting a video was obviously a horizontally oriented wide screen experience, matching the orientation of TVs and cinema. Instagram stories however were always vertically oriented to match the way you naturally hold your phone. IGTV nicely cultivates that. Some people always record vertically and that footage is then hard to show on TV, YouTube and such. Now you have a new outlet for that, enter IGTV.

If you have your material for your music video already recorded in upright position then you are so ready to edit it for IGTV! What I can see however is that not many existing recordings were ready for IGTV, so many decided to just clip off some footage from the left and right to keep the middle bit. The worst ones cut off parts of the titling so you can clearly see that its not the right IGTV stuff. As a viewer you feel cheated, because obviously you’re missing parts of the video.

But what if you have already recorded a video clip to be shown on YouTube and its in the landscape format? How to reuse that recording to make something that looks right on IGTV? What are the technicalities of the new IGTV video format?

Tunnel vision

The first step for me with the landscape clip for the Just a Game video, was to render it without the titling. All titling that does not fit the vertical format. The format to go for is HD, but then with reversed horizontal and vertical resolutions. So 1080×1920. With lengthy music video clips, you will find that upright portrait HD results in files that are too big in size. There is a size limit for regular video uploads, a maximum 10 minutes length and 650MB. The error messages from IGTV are not at all revealing unfortunately. A clip of 4 minutes length or more however, can easily go over 650MB. Then you will have to consider HDReady 720×1280.

IGTV Pan and Zoom

If you removed the titling because of the landscape format, now is the time to redo the titling for the vertical format to show the viewer that you have intended this clip to be in IGTV format. After that, all you will have to do is to use pan and zoom to cut out the upright sections of the clip that really show the user all the action in the clip. This way you don’t have to give away that the clip recording was not intended for IGTV. As always I am using Corel VideoStudio for the simple work and its capable of rendering the required output for IGTV. Now its time to upload! Tell me about your experiences!

Connecting the Logitech Craft knob to Ableton Live

Just in, the gadget of the month: the Logitech Craft. I was looking out for some more control over the mixing process and of course there are many controllers. When you already have an Ableton Push what more do you need? Well actually there is a thing about me and Push. I cannot use it blindly, so I always have to look at either the screen, or the controls, or the display. When mixing in the Ableton Live arrangement view it gets worse. Mouse, keyboard, screen, Push… It is at its best in Session View.

There were two things I was looking for. A high quality ‘chicklet’ keyboard like on my new Lenovo and it has an extra: A Knob. A dial that is touch sensitive and clickable to perform specific actions in any part of any program that has focus on your desktop. I am quite sure that your regular keyboard and a Microsoft Dial controller wil also make up good combo, but I chose the Craft to replace my old and clunky keyboard with media controls.

Unpacking and installing was the easy part. The previous keyboard was also a Logitech and it used the same Unified remote. Switch on and off and the keyboard was connected. Then a disappointment! No profile for Ableton Live. With a profile the keyboard recognizes the program its in and it immediately adds some shortcuts to the knob to control. For instance in a browser you can select a tab with the knob. In Photoshop you can zoom. In Lightroom you can change the exposure, or so I’m told. Standard functionality in other applications is controlling the volume of the PC and clicking it will pause/play music.

So there I was staring at Ableton, without being able to use the knob. I started diving into the settings, and there i found the Development Mode. Click it and you will need to also enable sending stats to Logitech. Tough but there is no escape.

From there you can select more programs to control with the knob and yes, Ableton Live is there!

And lo and behold, assigning up and down buttons allows you to control Ableton Live mixing with the knob. A new world opens up, where you can look at the screen. Listen to the mix and control a setting in Ableton Live with the knob. This was what I was looking for, more control and a better keyboard for the daily typing chores. Yay!

Fixing phase problems in a mix

Please note: If you are experienced in mixing this article will probably state the obvious. This blog is mostly intended as a “note to self” and everybody else that cares to take interest.

Recently one of my music friends Hanny told me that she had performed at a gig with her new band HannaH (check it out) that was broadcast live on local radio. Of course, she had asked for a recording that could be used for promotional purposes. There seemed to be no problems with the actual broadcast, but the recording behaved very strangely. When listening on a phone, the guitar disappeared. When you listened with headphones, your head would explode. The whole mix seemed strangely unbalanced. Phase problems… But we got out of it with a result that was even better than the original!

How did we get here?

These kind of phase problems probably have a very simple reason. In a stereo mix, somehow two wires in one channel were wired the wrong way. One bad cable can do the trick. What happens if some or left or right channel wires are wired the wrong way? The signals cancel each other out. Simple math shows it:

But the top signal seems ok, right? Well its drawn maybe a little incorrectly. The top signal actually has a little more richness of the waveforms to it and a little of cancellation. When used right, you will have a Phaser effect. Something you can find in any DAW and set of guitar effects as an effect that also wobbles the phase to add a little excitement and widening to a otherwise boring signal. Overdo it, or mistreat a stereo signal and you get cancellations and left and right stretched to far. It can result in headaches while listening.

How to get out of here?

So you now you have a mix with phase problems and its not your mix, just a stereo sound file. Aside from plugins with the purpose of fixing phase problems, is there a way to get out with just the tools you have? Fortunately for me there is. Ableton has a utility effect section that centers around treating left, right and mono signals from a track. I am quite sure that your DAW has similar built in effects.

The trick here was to duplicate the signal and create one track with the phase difference signal and one track where left and right were mixed into a mono signal.


Now one track only featured the guitar. Proof that there was a phase problem with just the guitar in the stereo mix. The other track featured everything except the guitar. When mixing both in mono suddenly I as able to remix the recording! Do you want more or less guitar in this song? No problem? All problems solved for HannaH. Good enough in mono, because the audio was for promotional purposes. Once again like in a Dutch football proverb: Every downside has its upside. Happy mixing!
