Inertial Slider

Can this be saved inside a LUA script, so one could press a button and load this in? I’m trying to figure out how I could call the Formula Device with my usual “load native effect” or “load VST/AU effect” scriptage?

vV:

I can instantly think of four situations where people will be glad of such a device. I’m sure there are many more! There is a certain similarity to them all, which might help you think in what ways the device could be useful to you.

You are an oldschool Tracker who doesn’t like graphical automation yet you want to be able to easily create ramps of effect parameters using pattern effect commands. At the new value in the pattern it will gradually change towards it, rather than a sudden jump, possibly removing the need for you to enter two values and interpolate between them (although the curve of the ramp is also different but it will be in most of these cases.)

You want to do a few small ramps in Automation (graphical) and creating a straight line, then extra point for each ramp and each plateaux can be time consuming. Instead stick the automation in Points mode and enter the new values where you want the ramps to start. (very similar to point 1 really!)

You want some random changes of a parameter using the LFO Device in Random/Noise mode but you don’t want these changes to be instantainious. Send it through this device (I believe it was mainly this suggestion, well adding Inertia to the LFO device, which brought the created of it with the Formula Device about.)

You are using Velocity to change values of a parameter live but don’t want the values to jump, partially as it can be an undesired effect, partly to help hide any imperfections in timing. With pad controllers now being so popular mapping velocity is more and more common. No reason you can’t use velocity from a traditional keyboard’s keys though.
The Inertia value will set how quickly the value changes to the new one set. This can obviously also be automated to give you different length ramps in output if you wish.

Here, have an upvote and a thanks.
I would love to, of course, understand it a bit more deeply as regards how the Formula Device can be hijacked to do actual LUA work.
Also, I’m totally vague on the aspect where the Formula Device could be used across multiple patterns, I can only see “LINE” and “LINEF” in ( What Is The Formula Device? )… the BEATS, TICK seem very complex to me.

Is there a way to print this kind of stuff in the LUA terminal to better be able to understand what kind of number crunching one would have to apply to use SEQPOS, BEATS or TICK, or TICKCOUNTER in a useful fashion?
