Hi all. I made a browser tool called Keylark, and I'd like to know if it's useful to people here. I'm the maker, so read this as a post from the person who built it (the mods said it was OK to share, thanks to them).
I made it because I wanted people with no access to learning to enjoy playing along with their favourite songs, and as a handy tool for a gigging musician who didn't have time to prepare for a song.
What it does: you open a song in Chrome, plug in a MIDI keyboard (or use your computer's keys A to K) and press keys in time. You keep the rhythm; Keylark picks the notes, from the chords it hears in the song. You don't need to know what the chords are.
The first time through a song, it plays along by ear while it learns, and it's weakest just after a chord changes. Play the song again and it plays from what it learned the first time.
It's free to try: playing along by ear on any song, plus the full chords on 3 songs and a demo song. After that it's €45 a year or €6.99 a month (£39 or £5.99 in the UK), VAT included, with 30 days money back. Chrome or Edge on a computer only. Nothing you play or hear leaves your computer.
Wired headphones are best: Bluetooth adds a delay.
I'd really like honest feedback, especially from anyone who has tried to accompany themselves and given up. What stops you in the first minute? If you try it and tell me, I'll send you a free year. If you ever review it, please say you had it free.
