Tempo LED?

This probably won't help, but you can always add the code / HW yourself.  Anything is possible given enough time, $, and skill. :-)

Most implementations I've seen of something similar (on commercial synths) have an internal clock mode for when you don't have an external source, and and external mode for when you do.  So you'd probably have to consider both cases if you do it yourself.

Do you really 'need' a tempo light?

(No disrespect)

I'm just not that sure what a light blinking in time with the beat will achieve?

If you are in bassline mode or drum mode, it's pretty obvious where the beat is.. (you get a nice scrolling led on the matrix) But that is for the MB-6582..

as you are all aware i am no expert on this but maybe there could be a solution involving a 555 timer  :-[ there good for pulses and metronome type apps.

hehe,... yeah, the 555, my favourite IC ;D

But you won't be able to use it in this situation. How does the 555 know how fast the tempo is set? The 555 really sucks when it comes to interfacing. The Frequency and PW is just controlled by two R's and a Capacitor, so it's not really accurate when using common 5% R's.

The easiest would be a seperate DOUT pin and some coding for the LED.

Under some conditions, a tempo LED can be very useful.

Ever try to get a drummer to "sync up" with a sequencer playback?

For some it's difficult, for some it's just impossible. and audio cues cannot

be heard over the live drums.

I once hooked up a "super-jumbo" LED that must have been almost an inch

across. I triggered it from one of the individual outputs of a D-110 rack synth.

Yes, there were driver electronics to detect the audio and drive the LED.

It worked just as I had hoped, but the drummer wasn't interested in being

synched to a machine.

I finally solved the problem by looping 24 frames of a short video clip of questionable

subject matter, then driving the playback from the sequencers MIDI clock.

It's not the kind of thing I could sell commercially, but it worked wonders to

to keep the live drummer on the beat, even through tempo changes.

I guess anything is possible if you find the right motivation. :-)

Getting back to your question: Any software that watches the MIDI clock can

control your LED, but a separate LED flash circuit with an audio trigger is more

programmable, if you have a spare audio output to drive it with. That way, the

flashes can be programmed into the sequence, and you won't need to worry about

different time signatures or MIDI clock resolution settings.

Or you can try the video method. ;-)

I swear it's completely true.

The classic Amigas have a program called "Soundscape" and one of the tools in there allowed very rapid fullscreen graphics changes mapped to MIDI events.

And yes, if you've ever tried to Sync to a drummer that doesn't like to be sync'ed.. it can be damn challenging.

Now how can I use this to make my next million? I'll have to sell twice as many if I need to share the profits with Jenna Jameson.
