I haven't tried from DAW to PD, but LoopBe is still fine for me from PD to Reaper on Windows (worked well with Ableton too)

@Spacechild1 Thanks, I'll give this a try. Sorry, really just my first time trying to get externals to work in Purr Data, that's really my problem i guess. Will report back if I get this working.

Sorry @Spacechild1, you're right. I'm working on windows OS, I've just put the vstplugin folder into the /extras folder for Purr data, and tried adding it as a library to the startup window, but doesn't seem to load. Just wondering if you had any experience installing it on Purr Data, I can't tell if I'm going about it the right way, or if it's even possible...I have no experience with compiling, so was hoping to avoid that...maybe this is a question more for @jancsika

@Spacechild1 Hi, thanks for all your work on this. I was trying to get this to work in Purr Data, but don't seem to have had any luck. have you heard of anyone using this in Purr Data, or is it even possible?

Amazing, that's really very helpful, thank you David!
I've been keen to explore beyond the standard lop, hip and bp too, so this will help a lot with that too. Yeah I'm beginning to understand the general idea of how it works, but implementing it is another thing. This will help a lot. One of those moments when I think I've learned enough to feel I've broken through to some kind of intermediate stage, and then...

Thank you, appreciate the link, and for feeding back about the Hadamard matrix. I guess there's no way around just having to learn how to read calculus if I want to work with filters...

I'm beginning to try to understand some basic reverbs from scratch. I know it's a huge topic, and at my level (not quite new to pd but no formal dsp education) I'm unlikely to get too deep into it unless I learn how to read algebra. I've looked at rev~1 + rev~2 to being with, but the reverb outlined in

seemed decent and well explained. It helped me grasp the basics of what is going on to begin with, but I'm still struggling to know how to implement some aspects of it.

It relies on "shuffling and inverting" multiple delay signals as an alternative form of an allpass, but I can't really understand how to variously invert multiples of a single delayed signal. Am I better off looking to the more standard allpass examples in the documentation H.15.phasor and passing the multiple delayed signals through this?

There's also two matrixes referenced, the Hadamard and the Household, and wondered if anyone had any tips on how they work, what it might look like in PD...are the matrixes combinations of additions and subtractions of signals, like in the rev2~ reverb example?

@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!!
