String quartet pro ,


It's a powerful metronome app that is super easy to use and intuitive to figure out. When you want a basic click to keep time, it doesn't get in the way. But when you want more control, it's ready for you! I used it to easily program complex tempo and meter changes for Bartok - something no physical metronome has ever been able to do, and a task which is cumbersome on other metronome apps. It seems like there might be a bug that makes editing click tracks very difficult after the initial creation. Overall, however, well worth the money!

...I just wish the accent didn't keep turning back on every time I make a change... But this is a small gripe!

Nicely written App!

LIke it's companion app ClearTune, this is a well thought out, well written app. I've tried a few others but this one is straightforward, and intuitive. The user interface is clear and easy to use. I never use emphasis because as a percussionist, play works with complex meters. I would be great if the app would save the current setup as a default, otherwise, this is my favorite and only metronome. It's loud enough and the visual feedback is helpful as well. I haven't tried the click track editor yet but what I really want is a simple, well implemented app, which this clearly is.

PS I'm clearly NOT "dissapointed" and don't understand how this designation got assigned.

Use it all the time...

This thing is awesome. Looks unobtrusive just to have open on my desk or stand. I only wish that when you open it it wouldn't default to the accent on 1. Personally I never use the accent when I'm practicing anyway, so it might be nice to be able to set the default settings when opened.

Also, I thought the thing going around in circles would annoy me... It doesn't. They grey look of the app is very low profile yet good looking.

It would also be nice if you could somehow add accents to different sub divisions. It doesn't seem like any metronome can do that yet.
