Soundbrenner Pulse Review

The Soundbrenner Pulse is an interesting product, a wearable vibrating metronome that syncs to your smartphone, or DAW. ( Amazon Link )

The folks at Soundbrenner thought I’d want to try it out for a review and sent me one along with the large body strap. There were two things I was interested in testing with the Pulse: How could I integrate it with my DAW REAPER, and also could it get me into a good habit of practicing guitar and bass again.

What is the Pulse

Physically it’s about the size of an Oreo, that can be worn on a wrist, arm, leg or chest depending on which strap you use. The face is touch sensitive and lights up with each pulse/vibration, an illuminated ring for quick adjustments of tempo surrounds the Pulse.

It comes in some really slick packaging. Not as minimal as an Apple product but a similar really nice experience opening it for the first time.

In the box you get the pulse, the charging dock, a micro-usb cable, two adjustable straps (wrist and forearm/leg) that the Pulse snaps into, a guitar pick, two stickers and the instruction booklet.
There’s a video below of the unboxing.

The Pulse is controlled by gestures, turn the dial and press on the top to start up, two finger touch to start and stop, tap 3 times for tap-tempo. It’s all in the manual and when you start the app the first time. Within a few minutes of use it feels really natural.

Many of the functions of the Pulse require syncing to your smartphone and their “The Metronome” app [ link ]. Things like time signature, different patterns, audible metronome, song mode, strength/length of pulses. You’ll want to use the app.

Practice Tool

I hoped the Pulse would help me get back into the habit of playing guitar and bass daily. Like every other piece of gear I’ve bought, it helps for a few days and then I go back to not playing for weeks. I don’t think it’s reasonable to expect a technology to correct self control problems, it’s a fancy metronome not a chastity belt!

I’m going to pause writing for a bit and practice with it for a while. hold on.

The Metronome app is pretty damn decent and I can see it being useful even if you don’t own the Pulse. Once you get the settings right you can pretty much put the phone in your pocket and do everything else from the Pulse gestures.

I was finding it hard to have really tight timing with the default pulse setting. I set it to short and powerful and that helped for me. I also use the audible metronome in ear buds. With the Pulse you can set the volume significantly lower in headphones without struggling to find the beat. You’ll be able to practice for longer without the headache from a loud click track.
I’m not able to go entirely without the audible click but perhaps that will come with practice.

The app includes song and setlist functions that I have not explored very much. It seems that a song consists of a single tempo with one type of subdivision and accent pattern. Multiple songs can be put into playlists.

I suppose to take full advantage of this you’d save each section of a song with tempo, subdivision separate. Chorus a little faster than verse, bridge has different accent etc. Then the song is sequenced in the playlist function. I could be wrong but I didn’t see a way to save multiple tempos within one “song”, nor did I see a way to set the number of bars for each song in a playlist. [ confirmed by Soundbrenner, it’s something they’re planning to add very soon ]

In a recording situation

I think it’s worth mentioning some things if you’d like to use the Pulse for recording.
First, ideally you’ll sync it to your DAW, which might not be possible. (see next section)
Second, the vibration isn’t silent, it can be quite loud. With electric guitars the pulses can be heard in the pickups if you want to wear the Pulse on your picking hand.

You might have to wear it on your ankle, with the strength on medium. Still I don’t think I’d want to risk it for acoustic instrument recording with sensitive condenser microphones.

MIDI Functions

The Pulse can also be used as a limited MIDI device. When synced to a DAW through another app: Soundbrenner DAW Tools [ link ] – you can receive the DAW’s MIDI clock, so the pulse vibes along with all your sequenced tempo changes. The Pulse can also send some MIDI to your daw for remote control.

There are two requirements for the MIDI functions and the DAW Tools app to work.
1 – MacOS Yosemite or higher. No Windows support yet.
2 – Bluetooth 4.0

My main studio iMac has an older Bluetooth device so I could only connect to my 2015 MacBookPro Retina. From there I was able to get the sync working pretty quickly in REAPER.

When DAW Tools is running in the notification bar, REAPER sees it as a MIDI device. Just enable sending clock to it and the Pulse receives the tempo from the project.

If you enable it as a MIDI input you can assign its ring and touch functions to actions. One obvious action to link to touch is play/stop. That worked ok.

Using the ring as a MIDI input was disappointing. Physically it’s an endless rotary encoder, in the software it sends an absolute value from 0 to 127. That severely limits what you can do with the ring. Jog/scrub, tempo changes, track volume I just couldn’t get working smoothly.

I emailed my contact at Soundbrenner with a request for an increment/decrement mode where the clockwise sends 1, 2 3, and counterclockwise sends 65, 66, 67. REAPER’s MIDI link mode “Relative 3 (65=-1, 1=+1)” mode works great with that.
At the time of writing this article that is not yet implemented but they said it’s something they’d like to do.

MIDI control is not that big of a problem really and it’s unlikely to be the main reason you buy the Pulse.

A note from the dev team

I want to also mention for the MIDI section that aside from the DAW Tools desktop app, you can also connect the Soundbrenner Pulse to your DAW via:
  • MIDI over Bluetooth, MIDI over Network via our Metronome app for iOS phones (see attached)
  • MIDI over USB via our Metronome app for Android phones
  • Ableton Link (only works for Ableton Live) via Metronome app
Using the above methods allow users with DAW running on Windows computers to also sync the Soundbrenner Pulse. Once connected, the Pulse will automatically sync with the rhythm in your DAW.

Conclusions

Overall it’s been a very positive experience using the Pulse. It’s not perfect but it’s pretty darn nice. It’s small and light with intuitive controls and good smartphone integration. As well, the Soundbrenner team was very responsive to my pre-review questions and feedback.
I’m going to keep using it for practicing. The DAW connectivity seems to be something they’re focusing on improving and hopefully things like Windows support, increment/decrement mode come before long.

It’s a unique and interesting product with good execution and I think it’s priced very well at $99 USD. Well done Soundbrenner!
