fffb-with-16-ldrs

could you explain in simple words, what is set input range

what should they be scaled/combined into ?

what shoud that values control at the end ?

you combine strange delaced Bnn Ann numbering 

instead of using straight 1 - 16 readouts, why ?

otherwise you could group and math them easier using vexpr for example.

Thanks for replying. And I'm sorry - I've been learning as I go and a lot of it is guess work.

I'm trying to record sound into the patch which I can then loop.

I want the patch measure the values of the 16 ldrs to  control filters incrementally so ldr #1 will be low and ldr #16 will be high.

At the moment the Ldr's range from readings of approx 48 - 800 depending on how much light is on them but I imagine this will be lesser or greater once they are installed in a blacked-out room with the films running. so perhaps 0-1023.

I thought I was changing the value/ range by using the * 2 (etc) message but imagine this is not right.

I have very little knowledge so not sure what vexpr is.

you can change scaling factor once input gets finally defined.

However, how do I get the frequency to respond to the ldr's? at the moment it's just the gain.

you can reuse all 16 LDR's or only some and scale them to control anything you want.

zmap is more secure as it clips output in case input exceeds set input range.

Scale on the other hand could inverse output, but it does not clip output

Thank you so much. I've been struggling on my own with this for days. I thought I'd gotten to this stage OK but then got lost down a rabbit hole with my ltd knowledge.

I have one last question... How do I then include this in my final patch?

I'll capture live sound to put through the ldr filter and looping it. I may want to layer some sounds...

If you need help with recording, looping, overdubbing etc,

I definitely do! That’s so generous of you. Yes please help :)

well, then you need to describe what you want to do ...

I want to be able to record a sample straight into max. Play on loop and allow the ldr's/ max patch to manipulate the sound directed by the ldr's/ light frequency.

I will then overdub more sounds straight into max.

What I'd like ideally is for each individual ldr to go from low-high but I imagine this is in scaling (#1 low - #16 high). Or I could try and include a synth so I can mess with the sound that way.

I think I should add more interesting filters.

please post patches as copy- compressed ,

I don't want to download patches and patches

I meant to give me hints how and what you want to record and loop etc.

Is 4 seconds really max length, do you manually start-stop recording,

how and when you want to overdub etc etc.

Is there anything in recording process related to LDR values or not ?

One could use tapin~ tapout~ with controlable input level, feedback

and let it auto record from the beginning by openning input into delay.

Thanks for the patch. I'd like to be able to control which sample/ loop I'm playing as well as be able to overdub. So similar to a looping station like my Boss where I can switch from each sample or delete the last one (so essentially build up layers and then delete them)

I;ve just looked at the karma~ varispeed audio looper but don't think this has that function although you can speed up and slow down,

This was the patch which I've added extra to to try and make the filters more interesting. Good or bad?

your 16 outputs are allready mixed into live.gain 

if you want to add effects after mix , then do it there.

then, I don't understand relation between audio playback of prerecorded samples,

you want to overdub into buffer that has sample loaded ?

and when you replace sample , overdub is gone too ?

I thought by adding the sliders I could somehow control each LDR individually because at the moment they are all responding at same frequency.

I'm basically trying to make something similar to leaf cutter johns 16 x ldr light-sound algorithmic instrument. But mine is on a big scale using moving images/ projections to 'play' the ldr's.

I just don't know enough Max to do this so doing things in mixed up ways.

I'm really sorry... i can imagine just how frustrating it is dealing with someone with very little knowledge.

I think in first place you must get 16 sensors set correctly.

I mean to check the range and adjust their sensitivity both in arduino code

as well as to scale them in max to get as much control range as possible.

there are different tyes of LDRs, dark-light resistance min/max can differ a lot,

one hast to adjust voltage divider resistor and also maybe reference voltage

to get maximum output range expected in the installation room.

Can I maybe help you with that, to start with ?
