LFO modulate only 50% of the destination

LFO modulate only 50% of the destination
« on: May 30, 2024, 03:13:20 AM »
Just checking if there a way to modulate a destination at 100% with the LFO.

Ex: I use Square wave LFO to modulate the OSC1 Shape. If OSC1 Shape knob is at Triangle, LFO will only modulate the shape between Triangle and Saw. If I move the Shape knob at Saw, LFO modulate between half Triangle Half Square.

Thanks

Which oscillator?  -  Hmm, I actually get different responses from Osc1 Shape (seems to be full amount? Sine to Square.), or from Osc3 Shape (LFO affects shape at Amount 0 [wth?], and I have to turn it below zero to get it to not change the shape... (?))

And I get some effect on Osc1 Shape when the LFO is at Amount 0 if the Shape knob is at 50% (sawtooth).

Weird.  I'm confused.

Edit:  Oh, I was gonna say...   Can you double the amount with an extra slot in the Mod Matrix?
- I can "undo" the LFOs effect with an extra entry set to -127.

Like I said, It's OSC1. I didn't try the other one. I'm just wondering if it's normal? If yes, how can I get 100% modulation.

When I turn the LFO amount, it doesn't change anything. I have no change, only the Modulation amount will affect up to 50% only

Try this:

Add a mod lane with DC as source and direct that to the wave shape. Set its amount to zero. Then modulate that mod slot with the same LFO that you are directing at the wave shape. That should hopefully increase the range but only when the square wave LFO is at its peak; when at its trough, it should add nothing.

I'll give it a try tonight when I get back home. The answer I'm looking for is, "Is the PRO-3 design to modulate an average of 50% with LFO or my unit have something?"

Also check if you get the same result when modulating with a triangle LFO. I believe that square is unipolar whereas others are bipolar so that might be the issue.

I tried both of your suggestion and I got the same result. + or - 50% range of modulation

It's seem to be the way it's design. I have similar result if I use the LFO Triangle to modulate OSC1 Octave. I don't get -2 to +2 Octave. It's more like the range of 1 octave who's modulate up and down

Ok now it's working with the DC. Thanks for the trick...Full range modulation :)

Great, glad it worked.

Right!
And then you could turn the DC Mod entry down to -127 and then modulating that mod slot could get 100% control? (Didn't try it.)  But yea, I was kinda thinking that way (use the matrix to do it).  But I do get an unexpected response at Amount 0 on the LFO. (Hmm, probably won't end up looking into that later.)
--  But that brings up a thing...  At the bottom of the mod matrix list are the 5 locked controls. (LFOs 1, 2, 3, and Env Aux 1 and 2). Do they act different for some reason?

I know, he found his solution! Cool!  Just thinking.
-- Like, when the Filter Cutoff is too hot from Matrix and Sequence control, you can turn the Filter Cutoff down further than the knob will get you with   "DC >>  -##  >> Cutoff"   entry.
Anyway...   Gotta love that Mod Matrix!

I can't believe I put this synth on sale lol. I decided to sit down and go deeper with the manual. Dave Smith wasn't joking when he said this is the last mono synth you'll ever buy.

No Kidding!  I love my Pro3!

I had always wanted a MiniMoog, but when I finally had the spare cash a couple of years ago I decided on the Pro3, and I'm  glad I did.  One of the really cool things I found (there are many!) was when I followed this guys* directions on making his MJ, "Thriller" album patches for the MiniMoog, but followed the directions on my Pro3, and got *really* close tones!

Cheers.

*He has two videos like that.
Here's the Baby Be Mine bass patch:
