    @romulovieira-me Under preferences > audio> select your sound card's line input. If it is the internal sound card there shouldn't be very many options, just a mic and maybe a line input (depends on your OS). Generally it's default set to the mic. (https://puredata.info/docs/faq/audioinput)

    Then in a patch, create an [adc~] object. Normally or initially, this is assigned to the mic on the computer, but if you have selected the signal line input from your soundcard you should be able to get a connection established. Getting the correct input and output set up can be the hardest bit of getting set up, stick with it and you'll find what is right for you. If you struggle with it, post a screenshot of your audio options and we can hopefully help point you in the right direction. If it's just a mono input, you may only have sound form one output of the [adc~] object. If you right click the adc object you can find out more, with examples etc. (you can do this with all patches, and is a great way to learn via practise.

    You will still have to connect the input sound to the [dac~] object, which will convert your signal back from digital to audio. Be careful though, it will be at full volume, so it is always recommended to put an object before the dac that will lower the volume (0 is silence, 1 is full volume, so lower decimals of 1 are advised before you know what to expect, maybe [*~ 0.1] to start).

    A small diagram to describe:
    {adc~]
    |
    {*~ 0.1]
    |
    [dac~ 1 2]

    explains how to do this if the audio input is selected as the computer mic, but if you change the selection you hopefully can find your guitar input (if you have an external sound card this will be a lot easier). Generally ASIO is recommended, as other basic sound cards can have very slow latency (particularly noticable if you're working with live physical instruments) and can crackle a lot too.

    It's worth searching this forum too, as you might find a lot more tips and help.

    Ah, I somehow missed this, @60hz thank you!!

    Hi All, I'm using GEM (very basically) but can't get that to display on a secondary display (despite the fullscreen msg in the help file - doesn't seem to work for me...), so have to run the GEM window from my main display and run my behind-the-scenes patch in the secondary display. Which works okay, but every time I go to open a patch or abstraction, it opens in my primary display (interrupting the GEM output window). Anyone have any tips as to how to offset where windows open, or ways of using secondary displays?

    Thanks @jameslo. I found int_fract~ an external which seems to parse signal integers from the fractal part of their float number, hopefully that will help.

    I'm not very familiar with using audio objects, but am trying to figure out a pulse train based on mixing a few different approaches from a few tutorials. I have something quite decent going, but seem to be getting this occasional creeping in of an incomplete phase cycle (see output of second wrap~ on right). No other signal is going in, yet I can't seem to see how this kind of half-cycle is creeping in. Anyone have any thoughts? I'm guessing something is happening between the samphold~ and the *~

    @jameslo Great, really impressive, thanks for sharing these! The octave divider inspired one is really impressive. I had figured out something vaguely like the sequencer example, just with threshold and tabread, but is v basic, this looks like there's plenty to unpack here, thank you!
    @kyro Yeah, thanks, been looking at autonomism and unpacking the patches, but couldn't find anything directly obvious. Was kinda asking in case there was something very obvious that I just had missed.
    @ddw_music thanks for this, I'll explore this and see what I can figure out from it.

    @whale-av Thorough and quick as ever, thank you David. I will have a look at the patch when I can.

    Might just be ultimately a dead-end to base things solely on signal rate if half-speed is the limit...phasor does just seem like a slightly unpredictible object, not quite reaching 0 or 1 with each cycle. I was drawn to how fluid its changes sounded, with Line~ being a bit less so, I guess thats down to the difference between sample and block-rate processing (I don't think I realised the importance of vline~ for sample-accurate processing...). Thanks again!

    Trying to explore using a single phasor as a clock for a patch, and trying to see how far I can push using just one as a way of learning. [wrap~] is great for multiplying a signal, but are there any techniques for dividing or slowing down the phasor signal, say if I want the 0-1 ramp to go half the speed, without changing the original signal? Pretty good with control logic, but audio logic is quite new to me, so just asking in case there's anything obvious, aside from using another phasor~ with half hertz of main one.

    Also was wondering about counting, and sequencing more generally. Has anyone got any good techniques for purely audio derived sequencing? Any sequencers I have been able to make are just based on multiplications of the phasor signal, so go quite fast through the phrase ([*~][wrap~][tabread~]). Are there any alternative techniques people might want to share?

    I've been trying using square waves/pmw as a kind of gate, but it seems a bit hard to sequence predictibly.

    Can't find where on the page, but I think the intro guide mentions the CSS is just included in a folder (winx84=PurrData>bin>css):
    https://agraef.github.io/purr-data-intro/Purr-Data-Intro.html

    I just changed one of the 8 preset themes that I liked the least, found it easier to learn enough to tweak it how I wanted:
    Think there are some limits to it though:

    Can try post more on this in a bit if you are still stuck

    Not really done this myself, but it appears to be an option in the put dialogue box when creating the second array
