audiomobster Posted September 29, 2009 Report Share Posted September 29, 2009 Would it be possible to add an audio output (really loud for headphones) which outputs a beep or a bell on each clock? I think this is really missing although I can do it with an additional cheap drum computer. :( Quote Link to comment Share on other sites More sharing options...
audiomobster Posted December 30, 2009 Author Report Share Posted December 30, 2009 An isd2560 seems the way to go. Quote Link to comment Share on other sites More sharing options...
lylehaze Posted December 30, 2009 Report Share Posted December 30, 2009 -Every Clock- is a very frequent event. I would find every 24th clock (or every 96th, depending on the resolution) would be more useful.. If you output a MIDI event, you get the option of selecting the sound, I usually use something from a drumkit. Have Fun, LyleHaze Quote Link to comment Share on other sites More sharing options...

Yep what I mean. >If you output a MIDI event, you get the option of selecting the sound, I usually use something from a drumkit. It outputs MIDI events all the time. What you mean?

Regards Uli The clockbox keeps time, but a synth makes sounds.. Why make sounds from the clockbox? Every beat (that's usually every 24 or 96 clocks) send the following MIDI bytes: 0x99 0x32 0x64 Send those out a MIDI port that's connected to a synthesizer. Change the second byte to choose a different metronome sound Change the third byte to change the metronome volume It's WAY easier than teaching your clockbox to make sounds.

audiomobster Posted January 2, 2010 Author Report Share Posted January 2, 2010 (edited) Why make sounds from the clockbox? Yea I could do it by MIDI events and with a synth, but that wasn't my intention. I don't want to spend an additional output channel, a voice of my synth's and maybe a mixer strip or even money for an extra synthesizer for just a metronome. For me as a drummer this feature seems to be missing. I think a metronome fits very well into the clockbox. Wouldn't the simple solution be connecting the 24ppqn signal at CORE::J14 to a shift register for counting clocks and quarters and then to the isd2560 Happy new year audio-mobster Edited January 2, 2010 by audio-mobster Quote Link to comment Share on other sites More sharing options...

One of the great strengths of this community is the diverse thinking of it's members. What you describe will work, no doubt.. but is it the "simple" solution? Instead of editing the code that is actually counting the time, you would rather pick up a hardware output and feed it into a hardware counter? That will work, but you'll also have to add synchronization signals to reset the counter when the clockbox is reset to zero. And if it is set to something OTHER than zero, your counter will be out of synch. And instead of using a synthesizer to create the audio signal that you want, you would rather design and build your own audio sampler from a chip level? Sure, absolutely. It CAN work. And it sounds like a fun project. Designing a sample playback device would be a great addition to the other projects we have here. But you must admit, it's a lot of design work to give your metronome a click. Maybe I could suggest a different option... that keeps the problems I mentioned above to a minimum.. If you can find an "extra" output from the DOUT card, you could either raise the output for one clock every beat (tick) or toggle the output at every beat (low bass thump).. That output can be used as a digital trigger, eliminating your counter chip and synchronization problems, or you could add a resistor and a capacitor right off the digital output to create a simple audio signal. You could also use it for a big LED, if you like the "flashy lights" thing. (great for loud drummers) There are many ways to do what you want. go with whatever looks like the most fun! :) Happy New Year, LyleHaze Quote Link to comment Share on other sites More sharing options...
nILS Posted January 3, 2010 Report Share Posted January 3, 2010 Just a thought: Use a timer in the PIC and some extra code to make a PC speaker style beep. PWM comes to mind or simply toggling a PIC pin at audio rate. Quote Link to comment Share on other sites More sharing options...
