unrise_lyrical Posted May 18, 2009 Report Share Posted May 18, 2009 Just checking if it is possible to have a Tempo LED (pulses on every 1/4 note from an incoming midi signal) on a mbSID? I had a read and saw someone else ask the question but saw he got no response. Dont think I have noticed it in any videos either...but yes, please fill me in! :) Quote Link to comment Share on other sites More sharing options...

fussylizard Posted May 19, 2009 Report Share Posted May 19, 2009 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. Quote Link to comment Share on other sites More sharing options...
Futureman Posted May 19, 2009 Report Share Posted May 19, 2009 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..RegardsMike Quote Link to comment Share on other sites More sharing options...
unrise_lyrical Posted May 20, 2009 Author Report Share Posted May 20, 2009 Its all good, no, I dont "need" it, just thought it would be nice feature to implement. I have a TR626 and its nice to have an led pulsing away in your peripheral vision to help you keep a track of things. Quote Link to comment Share on other sites More sharing options...
DJ Trago Posted May 20, 2009 Report Share Posted May 20, 2009 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. Quote Link to comment Share on other sites More sharing options...
SLP Posted May 20, 2009 Report Share Posted May 20, 2009 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 ;DBut 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.

lylehaze Posted May 20, 2009 Report Share Posted May 20, 2009 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 cannotbe heard over the live drums.I once hooked up a "super-jumbo" LED that must have been almost an inchacross. 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 beingsynched to a machine.I finally solved the problem by looping 24 frames of a short video clip of questionablesubject 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 toto 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 cancontrol your LED, but a separate LED flash circuit with an audio trigger is moreprogrammable, if you have a spare audio output to drive it with. That way, theflashes can be programmed into the sequence, and you won't need to worry aboutdifferent time signatures or MIDI clock resolution settings.Or you can try the video method. ;-)LyleHaze Quote Link to comment Share on other sites More sharing options...
unrise_lyrical Posted May 20, 2009 Author Report Share Posted May 20, 2009 thanks for the replies :) it sounds like it will be a bit too full on for my knowledge level so I think I may give it a miss for now. Later on I will probably build a more full on mbSID...maybe I will implement it into that one! Thanks for all the help and advice guys! I appreciate it :) Quote Link to comment Share on other sites More sharing options...
stryd_one Posted May 29, 2009 Report Share Posted May 29, 2009 Or you can try the video method. ;-)OMG I have heard some funny drummer stories in my time but that one is definitely in the top 5. I just woke up my flatmate with my raucous laughter :DPr0nsync © LyleHaze 2009 Quote Link to comment Share on other sites More sharing options...
Therezin Posted June 1, 2009 Report Share Posted June 1, 2009 questionable subject matterYou hooked your drummer up to a MIDI-porn sync? Quote Link to comment Share on other sites More sharing options...
lylehaze Posted June 1, 2009 Report Share Posted June 1, 2009 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. Quote Link to comment Share on other sites More sharing options...
nILS Posted June 2, 2009 Report Share Posted June 2, 2009 Some of the profit would surely go to Peter North as well, no? ;) Quote Link to comment Share on other sites More sharing options...
