Questions about a metronome stompbox.....

[william]

I have been asked by a friend of mine to build a visual indicator for a metronome.  The drummer plays to one in order to sync up with a sequencer.  Some songs start with the guitar player only, so he needs to see what tempo he is to play at.  He has asked for two led's, one for count one, the other for the beat.  I have a schematic built, and breadboarded it but I'm now looking for suggestions for improvments.  Right now, it has an audio jack for the click track, and two pots for sensitivity control.



Thank you for taking a look.

So this is a display for your click track? The track has accents and the other led lights that has higher treshold, and other led lights on all clicks?

Seems like interesting and useful gadget when playing with sequencers and when doubletracking...

Well, how bout in principle of some opamp comparator led VU circuit? I sure have few circuit snippets around for this, but dunno if I find them just now, but maybe later... I have one old circuit from Finnish mag that uses just CMOS 555 and very few components for peak detector, you can adjust indication level and how long the detector led shines simply, the only drawback is you can zap the mos 555 if you feed it with signal and power is off...
