Is there a way to randomize the ratcheting of notes in a sequence? It’d be nice to be able to randomize this every time the sequence is played.

Is this possible?

Hi Toom,

RTCH CT (Ratchet Count) is a MOD Destination (pg. 51).

Using one of the MODs, set the SOURCE to Sample & Hold, then set the MOD DEST to PMG.

Now choose RTCH CT as the programmable destination using the CONTROLLERS MENU and turn up the MOD AMT knob.

But is there a way to randomize which note in the sequence gets the ratchet every time the sequence is repeated?

Well… to my knowledge, there is no global Ratchet On/Off parameter; each Step has its own Ratchet On/Off switch.

But, when the Ratchet Count is 1, Ratchet is effectively Off.

So you could use a non-sync’d Square Wave LFO to modulate RTCHT CT.

Set MOD DEST to PGM: RTCHT CT and then set the MOD AMT knob to achieve a specific Ratchet Count.

Now it will alternate between a Ratchet Count of 1 and x. Set the LFO to a non-sync’d Rate that’s unrelated to the Arp speed and it will act pseudo randomly. Experiment with lots of LFO Rates to find a desired result.

{Don’t forget to turn a bunch, or all, of the Steps’ Ratchet Counts to ON, or little will happen.}

You could even use your other MOD’s LFO RATE destination to modulate the Rate of your Square Wave LFO.

That would create an even better pseudo-random effect.

But, I agree that a global RATCHET ON/OFF destination would be a very useful future parameter to automatically embellish your Arps.

It works, thanks Dan!

I’m going to have to try this when I get home. Sounds like fun!

Good grief! What kind of mind does it take to think up something like this? :smiley: Thanks, DemonDan, this is great!

I’m still trying to figure out what Ratchet means. To the manual!

great trick, Dan. all kinds of applications for it.
