Tempi Beat Detector by Made by Windmill, LLC

Made by Windmill, LLC recently released Tempi Beat Detector. The app is designed to settle disputes between bandmates over who is truly keeping time, and it can do that across multiple instruments. Tempi sports 4 different beat detection algorithms that are running simultaneously, while self-tuning to figure out which of those is giving the most accurate results.

Tempi Beat Detector iTunes Description:

Tempi measures you and your entire band’s tempo live, while you play, and lets you analyze the performance when you’re done. It's like a reverse metronome.

* Tempi listens while you (or your entire band) play.
* Tempi reports the BPM (beats per minute) of your performance in real time with remarkable accuracy.
* When you’re done, Tempi lets you analyze the recording so that problem areas can be pinpointed and improved.
* Use Tap for Tempo to quickly get a BPM reading at any time.
* Switch themes for easy nighttime use or just to suit your style.
* Export the audio recording of your performance to keep or share with others.

Tempi is free, but has features you can pay to unlock. Unlock all features, including future ones we add to Tempi, for a one-time cost. Or you can individually unlock Unlimited Recording, Themes, and Audio Export.


In a band setting, place the iPhone or iPad in a position where the entire band can see it so everyone will know when the band is speeding up or slowing down. When you’re done playing the song, press the stop button to analyze the performance. You can scroll through the entire song, isolate where the tempo sped up or slowed down, and play back the song to get an idea of what went wrong.

Tempi is great for individual practice too. Use it instead of a metronome while practicing to pinpoint problem areas in a piece of music that you’re learning. If you can play through an entire song with the tempo only changing by 1 or 2 BPMs, you’ve arrived :-)

Tempi works best when there’s a distinct “pulse” to the song, like a kick drum/snare or a repeating chord, and assumes the player is trying to play at a consistent tempo. With less structured music it still does quite well but may occasionally report incorrect tempos.

Live Performance with iPad: AUM iOS & MIDI Controller

Reader Pink Sky Music's YouTube name makes me think that at some point we're going to find out that he's the arch-nemesis of Red Sky Lullaby. Although it is too soon to say who will be the victor in their inevitable battle:
No matter who wins, we'll all be seeing a shade of red. This summer at a theater near you.

In the meantime, Pink did an excellent demonstration of AUM as a live performance mixer. The demo jam is good enough to standalone, but he's also provided a detailed explanation of his workflow and signal-chain!

Video Description:

In this video I demonstrate how to use AUM, one of the most versatile iOS music apps, as a live performance mixer using a Novation Launch Control MIDI Controller. Read More for an in-depth workflow explanation!

Workflow:I created five loop tracks in AUM and loaded loops that I had recorded using AUM earlier. All loops were created by recording various iOS music apps into AUM. I then mapped the Launch Control to control each loop track: each vertical row on the controller corresponds to a track in AUM with the top knob mapped the filter cutoff, the bottom knob mapped to an effects send, and the button mapped to loop start/stop. MIDI routing with AUM is super intuitive.

For performance effects, I setup two effects bus tracks in AUM - one bus with Audio Damage's Dubstation 2 Delay for the melodic loops, and one bus with Audio Damage's Replicant (glitch/repeater effect) and Blamsoft's Resampler (bit crusher) for the drum loops. Also, there's a Master bus with Audio Damage's Rough Rider 2 compressor that all audio is routed through. All of Audio Damage's iOS effects are top-notch, and since they're AUv3 format, they can load inside of AUM and don't require their own screen.

Once it was all setup, I just kinda hit play and winged it. AUM has an internal clock that keeps all the loop tracks synced - the workflow feels very similar to working with clips in Ableton.This is my new preferred method for composing and performing live with the iPad.

Xequence Update

Xequence got its first update today, adding several improvements including enhancements to MIDI Sync.

What's new in Xequence v1.1:


- Much smoother zooming and scrolling in all editors.
- Part previews now show all controllers and notes, and look much nicer.
- Enhanced MIDI Sync. The "Sync" option in instruments now has a new "Relative" mode (old mode is called "Absolute"), which is compatible with pattern-sequencer-like apps and hardware, like Ruismaker, StepPolyArp, Korg Volca Sample, etc.
- The "MIDI In" button on the Settings screen now blinks when the app receives MIDI notes or controllers, for easier setup of incoming MIDI connections.
- Much more accurate timing on MIDI In from apps and devices that support MIDI Timestamping.
- You can now create multiple instruments with the same MIDI destination AND channel. Useful, for example, if you want to use different scales / root keys for the same synth in different parts of the song without constantly switching scales. As root key and scale are set per instrument, you can just create one instrument per scale / key, with the same destination and channel, and a corresponding track per instrument. Also, if you need more than 3 controllers, you can just create several identical instruments, but with different controllers.
- Looped parts will now loop for 64 bars beyond the song end (used to be 32).
- Basic iPhone X compatibility


- Fixed missing or wrong MIDI notes during recording.
- Fixed possible crash with MIDI input and switching tracks.
- Fixed possible crash with certain MIDI input sources.
- Disabled the "Xequence Source" MIDI source, as it was not used and only caused confusion when setting up MIDI routing.
- Various fixes, optimizations and usability improvements throughout the app.
