Installing Pure Data on the new Retina Macs I’ve just gotten a new Retina MacBook Pro and while I’m not going to use it for audio most of the time, I wanted to get Pure Data running on it so I could use my Guitar Hero patches without high latencies ([hid] is available on the Mac version of Pure Data).…

Configuring Raspberry PI for audio I now have my Raspberry PI device in hand and I’ve been trying to get it set up for some audio fun. Some things were pretty painless, like setting up Pure Data. I installed the Pd-extended Debian package and used apt-get to install missing dependencies and I was off to the races. However, getting Jack…

Getting 64-sample audio latency on Windows 8 I recently spent some time setting up a new audio rig with my Presonus Audiobox USB audio interface. I won’t promise that you’ll get the same results I did, but I’ll share what I learned along the way to getting lower latencies with my setup. I’ve written a little bit before about the…

The state of USB audio on Windows I recently got a new audio interface. I had a cheap Behringer UCA202 USB interface that I had been using for a while and I thought it was time to get something a little nicer. I settled on the PreSonus AudioBox after considering the Focusrite 2i2 I read a few reviews of the…

Running Pure Data patches full screen I’ve been working on some Pure Data patches that I intend to use as dashboards during live performance. I want these to be running on my personal monitor display that faces me. The audience won’t be able to see it but I still want to run full screen without any distracting borders, etc. There…

Understanding data flow in Pure Data part 1 Quick, what is the difference between the following two patches? [](https://audiodestrukt.wordpress.com/wp-content/uploads/2012/12/image5.png) Visually they are identical, but if you take a look at the number box at the output, that should give you a clue. The patch on the right has an off-by one bug in it that isn’t obvious by inspection of…

Building Pure Data externals on Windows I recently built the beatpipe external under Windows, and it had a few tricky things to remember so I’m outlining the process here. Externals are usually pretty easy to build under Linux where the GCC tool chain is already installed, but on Windows you have several different ways that something can be built. Some…

MIDI software roundup I’m doing a quick post on my current MIDI software setup on my audio laptop currently – partly for me and partly for you. I seem to forget which bits of software I’m using during a particular period of time, DAW-epoch if you will. In the dark ages I used to use Hubi’s MIDI loopback driver, but…

Hacking on the APC 20 I recently got an AKAI APC 20 Ableton control interface at a local used music store. I have been hunting around for one of these pad-style controllers for a while, and this one was priced right. I don’t think I’d ever buy a Monome, mostly due to the price, but the controller market seems to…

MIDI with Ruby I was disappointed with not being able to use Pure Data on Windows to send the appropriate MIDI sysex message out to change the operating mode of my APC20 when I was doing this text scroller patch. For some reason when I sent the sysex start and end bytes (0xF0 and 0xF7) messages to the APC it…
