Yes it does work with the Rocksmith cable and we've seen a bunch of users discovering that. As you point out, pitch detection can be a little sensitive with that cable (depending on the guitar), and you're right that we could / should do some calibrating to improve it.

Yeah the core of the pitch detection is in Flash, so that it can work in browsers that don't yet support HTML5 audio, such as Safari, and in older browsers. But where possible, we do grab the audio and do some of the signal processing using HTML5. Also, all of the UI is HTML5 and JS.

Sure, please do keep the feedback coming. You can message us thru the site when logged in (we use Intercom for this) or email us at [email protected] .

Haha - Actually, we've thought about it multiple times. With the right teacher, it wouldn't be that hard!

Haha, sorry about that, probably a bug.

If you don't mind sending us OS / browser / version + the lesson you played, we can try to debug. Our email is [email protected].

Great points, and thanks so much for the kind words about the tuner.

Agree that sheet music would be great, and also that the lessons do feel a little quiet / less lively than they could. Your voiceover idea is really cool. We've also thought about adding backing tracks as another way to increase the energy level.

We've also run into that wraparound issue you describe, where a section that starts and ends with the same note can cause an issue when you get to the end and sustain the note. I think you're right about the solution, i.e. better attack detection by looking at the amplitude of the signal.

Yeah I'd love for us to make a piano version too. We haven't started it yet, but maybe it's percolating - I've been spending a ton of time on the piano lately. :)

Yeah we like HTML5 / WebRTC a lot better too. In Chrome, Instinct actually uses WebRTC instead of flash to access the mic.

We had a few issues with Firefox WebRTC though, still trying to work through those.

Awesome, so glad that your first lesson was a good experience!

Yeah I agree about the layout of strings in tab notation being confusing as a new guitarist. We wanted to default to the standard layout for tab, but then it gets a little confusing because it's different than the guitar layout below.

One trick with Instinct is that you can flip the notation by clicking on the string names along the left side of the tab.

In the future, we also want to give you the option to flip the guitar, but so far we've only implemented that in our pro courses (i.e. the courses that have pictures of real teachers on them).

Great point, totally agree.

Ah in demo mode, just move the mouse over the highlighted strings at the bottom and they will play. No need to click or anything.

We first launched here on HN 1.5 years ago, and we're pretty excited to share v2.

Our goal with Instinct is to add deep interactivity to any music lesson. We think that one day, every lesson on YouTube might have pitch detection, scrolling notation, a scoring system and personalized feedback.

This v2 is a big first step in that direction. We've teamed up with a bunch of online teachers to create fully interactive video courses, as a way of showing what's possible with the tech.

There's much more to do though! At this stage, we're looking for as much input as possible from users and teachers.
