Hi,
i am stuck with a problem, i want to modulate a bitmap knob using an LFO, but this doesnt seem to be possible,
sorry i have been using synthmaker for a while but i am still rubbish 🙁
this is probobly a simple thing but i am useless
any help appreciated
thanks

Hi,
Something like this:
Edit: Fixed input range.

Thanks alot for the input!
the OSM doesnt seem to be working in the way i was meaning though,
The bitmap knob oscilates but does not actually out put the oscilation,
to reiterate my problem is that i need to oscilate an input which only accepts a F in a circle therefore i can only use a bitmap knob ( to my knowledge ) when i add the bitmap knob and move it i get the desired effect but i want this to be triggered by and LFO, so in effect the knob will move back and forth depending upon the frequency of the LFO

Yep,
Fixed the range and made it green only:

An OSM should never module green data at or near Sample Rate: 1) Eats alot of CPU, likely more than just multiplying Stream 2) Will end up being semi-randomly jumpy, as you can see by spinning the Float value before the knob in the last file. Sure a De-zipper will help smooth out the values, but the output still may not be as curvy as you wanted.

Good example Mo, I need this too. But if you can do something real with GUI (i'm not 🙁 ) so here two proposal: Method 1. When one make "Left Mouse Click&Hold" over knob area and start to drag, then external LFO sets off and knob' output is modulated by mouse. After release mouse, knob' output starts to be modulated by LFO. Method 2. LFO is just added to current knob' value. So after load, or after last succesful "Left Mouse Click&Hold&Drag&Release", LFO added to value that sets after load, or sets by mouse moving. (And knob' pointer changing accordingly). Values out of [Min..Max] just clipping.
Method 2 is very interesting to me for slow random modulation of volume, cut freq etc. Clipping and rescaling I can do by myself 😀

Fixed it with a Float Select instead of Float Switch.
I'm not sure how method 2 should work.

Here what I mean:
Dont know will it be useful to someone else but for me is very helpful, so thanx to pjbridger for idea and Mo for basic schematic! ))
Clipping (inside MinMax module) can be replaced by kompressor, or just switch off.
Mo ·
Ah, but better place the clip before the preset module as preset need range 0-1.
lesobrod ·
Thanx for smart advice! In fact, everyone who'll be use this schematic should carefully set LFO and knob ranges so clipping will be not need at all.
