I had some time during vacations and I wanted to try running Miller's espd version. Here's a small tutorial.
INSTALL ESP-IDF (IoT development framework)
mkdir ~/esp && cd ~/esp git clone -b v4.4.2 --recursive https://github.com/espressif/esp-idf.git cd esp-idf ./install.sh esp32
INSTALL ESP-ADF (audio development kit)
cd ~/esp && git clone --recursive https://github.com/espressif/esp-adf.git
SETUP ENV VAR
export ADF_PATH=~/esp/esp-adf && . ~/esp/esp-idf/export.sh
download espd: http://msp.ucsd.edu/ideas/espd/
cd espd git clone https://github.com/pure-data/pure-data.git pd cd pd git checkout 05bf346fa32510fd191fe77de24b3ea1c481f5ff git apply ../patches/*.patch Edit main/espd.h put your wifi credentials and the IP of the computer that will control espd: #define CONFIG_ESP_WIFI_SSID "..." #define CONFIG_ESP_WIFI_PASSWORD "..." #define CONFIG_ESP_WIFI_SENDADDR "...." mv sdkconfig.lyrat sdkconfig idf.py build idf.py -p /dev/ttyUSB0 flash (hold boot and then press reset on lyrat) idf.py -p /dev/ttyUSB0 monitor (Ctrl+] to exit)
- open pd installed on (SENDADDR)
- open test-patch/host-patch.pd
If connected this message (ESPD: sendtcp: waiting for socket) will stop and you will see the mac address in the host patch.
1- click on [send pf begin-new poodle .<
2- click on [line 0, auto< to send the defined patch (esp-patch.pd)
3 - click [send pd end-new<
4 - connect headphone, play with [send f 440< and [send f 660<
- Use mono [dac~ 1] only
- Add this to your patch:
- in host-patch.pd change [read your-patch< -> [text define patch] redo step 1 to 3
Would love to play more with the code, right now I am not able to load complex vanilla patch. Also using the AUX (or built-in microphone) would be awesome (but I'm wondering about the round-trip latency (would it be under 15ms)).
@lo94 Hi, I am using PD with an old Surface Pro 3 on linux. You can also use an external HDMI + usb touchscreen monitor.
PD is not really touchscreen friendly, what you are asking (toggling multiple notes (sequencer) with a single swipe) isn't possible without some hacking.
All the best
