sdk5 - creating gate sequencer, idea and thoughts

Post by faxinadu »

gate sequencer idea

i really have no idea how it is done, and thought about this while lingering before falling asleep. tried implementing it but came up with problems with the lfo acting as ramp. so my question is, is this a viable way for creating a gate sequencer? what other methods are there?

midi clock freq out ---> divider set to 1/16 ---> freq in of saw lfo (for ramp)
8to1 switch, with on/off buttons on each input representing 8 "steps", the switch modulated by the ramp

midi mvc gate out
+
output of switch
--->
"AND" logic function
=
gate sequencer



thoughts?

I don't think the AND logic function will work, as I think the output is like a gate as well. But just use a VCA instead.

Seq Out/Gate can be 0 or 1

Out = 0 * MVC = 0
= 1 * MVC = MVC

Now you have my gears turning:
You can also swap out the VCA for an adder, and make the seq out can be a partial instead of gate (to shift the MVC input up & down), or a bipolar value to shift MVC freq up/down.

Out = .5 + MVCfreq = you get the idea ;)

hey can you explain a bit more? not following what you mean with the maths

thanks!


i just thought about the "and" so that there will only be a "gate on" message when of course there is bother midi (key pressed) as well as a "on" on one of the steps.

Sorry, you are absolutely correct.

I had thought the MVC Gate out was written as MVC Freq Out. So using AND logic is fine!

yes but your idea i think also a nice thought, perhaps a way to take this further, to make a note-sequencer... now you got my brain wheels going :D
