Guest kostix Posted November 22, 2004 Report Share Posted November 22, 2004 Anyone ever tried hooking up a capacitor between the middle pin and ground of the potentiometer while its connected to your midibox ? :)I connected a 2200uF cap to one of the pots, and when I turn quickly the pot to some direction, and suddenly stop it, the value is decreased or increased logarythmically cause of the cap discharge time thru the pot itself to the ground ;)This can be useful to create really nice "analogish" fadeouts or fade ins :)Just my bitciao Quote Link to comment Share on other sites More sharing options...
goyousalukis Posted November 23, 2004 Report Share Posted November 23, 2004 Neat Idea! I'll give it a shot.... Quote Link to comment Share on other sites More sharing options...
Duggle Posted November 23, 2004 Report Share Posted November 23, 2004 if you would like to use a physically smaller cap to privide ths same "smoothing " effect, do this: With the positive side of the cap still connected to Ain, wire a resistor between the wiper of the pot and Ain.This will lengthen the time constant.Time constant can easily be calculated as R*C (in ohms and farads). Basically if you scale the resitor up by a factor of 1000 then you can scale the cap *down* by a factor of 1000 and have the same response!With a 10uF cap try say 22kohm resistor.

shed Posted November 24, 2004 Report Share Posted November 24, 2004 could this not be done in software, by calculating some sort of moving average, this would meen that you could switch it on or off witch would be cool Quote Link to comment Share on other sites More sharing options...
Duggle Posted November 24, 2004 Report Share Posted November 24, 2004 Of course.But this is just free form experimentation, something that can be setup (and deconstructed) in 5 minutes.Some peoples PC's take more than 5 mins just to boot up ;) Quote Link to comment Share on other sites More sharing options...

shed Posted December 10, 2004 Report Share Posted December 10, 2004 i guess so, but if you could program this in mios then you wouldn't need any hardware changes Quote Link to comment Share on other sites More sharing options...
Guest kostix Posted December 20, 2004 Report Share Posted December 20, 2004 i would still go with the hardware..its not so much stuffonly a cap and a switch, maybe even have a rotary switch to be able to switch in different caps, or simply a pot in place of the R in RC.this way u get *truly* logarythmic decay, without loading the processor anyhow and no misc software change ;) Quote Link to comment Share on other sites More sharing options...
