Multiplexer, Demultiplexer

Only for curiosity.. can you explain it a bit ( don't know what you're talking about) ?

Yeah, I don't understand it either 😉

The multiplexer bus version? whats a demultiplexer, i have never heard of one before.

I think a demultiplexer is the same as the selector. Basically the opposite of a multiplexer.

ambitechniques, what do you mean by "analogue"? you probably mean multiplexer and demultiplexer for sound,if that's the case it is already implemented by the Selector and Multiplexer components.

Yeah i was guessind that ambitechniques means selector, maybe he hasn't found the modules in the toolbox or something.

I'm hopeless at explaining things but I'll try. We already have a multiplexer with 1 input and an X amount of output, but, the input and output is a digital pulse. Now, what if we had a multiplexer that didn't have a digital input but had an input for sound or OSC poly or mono and say 8 outputs of the input . The counter connected to the multiplexer switches on each of the output in sequence. Each of the outputs could be connected to 8 filters at different settings to give slightly different sounds. Each of the filters ( that have defferent filter levels ) could then be connected to a 8 input demultiplexer ( selector ) which of cause will give 1 output. I think the counter will also be connected to the selector too but, it will have to reset when it counts up to 9 I think. I would be very happy if I could make what i just tried to explain and make it count at the host tempo rate. Hope someone understands what im on about.

Analogue multiplexer and demultiplexer is an I.C chip.

Thanks

well, basically you're describing an event sequencer

Take a look at example.osm, bottom section. first ( top-left) group of bars are controlling the freqcuency of oscilator. I mean. The corresponding frequency to the midi note played is the input and a relative frequency to it is the ouput. This relative frequency is proportional to the height of the bar, and the duration oof the "bar" is set by the speed knob. It also has the looping you requested

Same could be applied to other things. Second bar group is used in similar way to set teh cutoff of the filter, and third and forth used to control the ammount of fm that goes from osc1 to osc2 and osc2 to osc3,. respecively

It should be posible to modify this to adapt to any parameter you coudl think off

Thanks unkargherth 🙂
