wow!! This is amazing!! I would help if I could!

Edit: I've always thought a detailed and well documented clone would be a great "Capstone project" for a book/walkthrough/introduction

To do ratcheting, you can make a sequencer like this, out of expression nodes.

This is just a start, but you can see one way to do it! :)

That is an interesting idea. I think the way it is set up needs a little tweaking to so that overlapping gate signals don't just keep the gate high. In the posted patch, the ratchets have all been set to 1 and it makes every step repeat 9 times.

Ok, sorry if I am updating this too often. I will probably update this one last time when I have added (or rather figure out how to add) slide per step and step skip. I just got a head of steam rolling when I came back from a concert and did a bunch more work on the sequencer.

Thanks Mark for your post, the 0 step unlocked how the sequencer should work in my mind.

Following with interest! I've little to add I'm afraid.

Had a look at your patch and I can't quickly get my head around the internals (but still had fun playing with it!)

However as a standalone sequencer patch here's how I would approach the slew per step, not sure if that will work with your design though?

afta8 you are a genius! I will get right on it!

The idea just needed a little more tweaking, and I couldn't resist the challenge :)
So here's a demo sequencer that has the skip step functionality.

Note that the counter node has been modified to use the mod function to cycle instead of the conditional, that works better for this kind of thing.

Nice job on the last iteration as well, I like the slew per step!

ohh nice. exactly what i wanted for my sequencer :)

Cool stuff here guys! Following with interest...

My two cents: If you check out the ES-8 Sequencer video, you can see some techniques that might be useful for this - basically using sequencers to sequence other sequencers. If you use a sequencer with a multiply node to change the gate height as the gate goes through the sequencer and onto the synth, you can easily make a step skip by just turning the volume all the way down (i.e., the gate height = 0).

So I spent about an hour and a half trying to solve this and basically finally understanding the way @afta8's skipping mechanism works. Really clever! I see there being two problems when adapting it to a bidirectional count.

First is that the secondary mux used to calculate the number of steps skipped needs to be adapted to the direction of the count. I added a direction out to the ^v count so that it outputs 1 or -1. I am not sure how to address this. maybe another mux with inverse wiring?

The other and more difficult problem is how to get a counting mechanism based on modulo to work when counting backwards. I'm a little sleep deprived at the moment and I could feel like there is a simple solution but it eluded me.

I am leaving things for a couple of days while I go on a business trip. I may work a little here and there but I think I will need a cup of coffee AND a good night sleep before I can get this sorted out in my head.

>That's a Manhattan Project for people here... :)

Indeed!

I think the terms are a little bit in the context of the Metropolis. The pulse count for each step has 4 modes (one long pulse, one pulse for each clock trigger, just one short pulse on the first clock trigger, and mute). The skip feature is there to enhance the performance aspect of the sequencer which is tied to creating melodic passages rather than fitting into a fixed number of beats like 8 or 16 step sequencers.

Brownian in the context of the Metropolis is 50% probability to step forward or backwards, again to be more of a permutation of an intentional sequence than a purely random mode. But of course I am randomizing all the parameters anyways :P

Thanks for the feedback though, when I get this thing working, refining and clarifying will definitely be the next task.

@RobertSyrett, I think I cracked it, see attached patch.. I made a mini sequencer to demo and jam with.

Forward/Reverse both work with skip step buttons, there is a dial that sets the direction. There is also a switch for the brownian motion and another switch to reset the sequence. Sequencer doesn't use a counter either :)

This is a lot of fun to jam with, can totally see why you are GAS-ing over the intellijel hardware :)

@afta8 Thanks for putting up both versions! I went through the dev version and carefully added text/comments so I made sure I knew what was going on.

So I modified the 8msq into a counter for the Molecule Seq and it works beautifully! I eliminated the max step function since there is nothing the max step can do that you can't do with skipping steps. Pretty much all the per step parameters are knobs right now so that you can just plop an external input on it for diagnostic purposes. Now I will make the patch look nice to my tastes on the inside and front panel. Probably upload one last time and call it a day. Thanks again, afta8!

So excited to try this! Thanks hugely to you, and everyone who helped out.

That's a nice touch!
