hi there,

just wondering if there's an easy way to look at a gate's output and only output the "ons" from that gate...
i feel like there's a lack of information in the description for such things in the manual...

thanks,
b

I'm not sure what you mean ... could you try other words? Maybe a description of what you want to use it for.

sorry;

i have the gate input from the midi note ins (velocity), and i want to count the note-ons... i want to take those "high" or "greater than or equal to 1" values and use them for things like resetting, or counting, etc.

also, since i know that you know this off the top of your head (great patches, by the way; love your contributions to this forum), can you tell me of an easy way to count to 32 and then output a "high" message, for ex?

Ah got it .. maybe ... thought you meant the logic gate module Laughing

You can just use the ClkDiv module from the logic page, it's output will go from 0 to 1 after it's input went count times from zero to 1.

But you only want to count when the velocity is over a certain value? If so use a comparator module (level/complev) to compare the velocity against a preset level, you can AND that signal with the gate output to get a logic signal that goes active when the gate goes on and the level is above the threshold ... something like that?

And thanks for your kind words!

certainly.
that gives me more than enough info to go by;
thank you.

one more thing:
can you tell me where i might be able to check into more information like this and more... i'm also interested in bitshifting, packing bits, demuxing, and how to sequence without the bulky sequencer modules...

thanks...

Some links for the NM Classic come to mind like James Clark has a chapter about logic modules. Rob Hordijk has a logic workshop at the Clavia site and he has some info on his own site as well. We have some building blocks on this forum - there might be useful stuff in that for you and Sebastian Berweck's patcher's toolbox ... that's about it I think ...

BTW the sequencer modules are pretty efficient, building comparable functionality with random logic will always cost more resources. You can use multiplexers though for sequencing when 8 steps will do, and that gives some flexibility as there is no need to feed it constant values to sequence over.

What do you mean by bit packing?
