recur v2.1.0 release notes

recur_2.1.0 release notes

recur_2.1.0 is the new experimental firmware. here are some details about what is new and how you can try them.

changes:

• can eject all usb-drives from settings->system->EJECT_USB_DRIVES
• can use mouse/touchscreen to control shader params (default mapped to x->x0 and y->x1) , enable in settings->user_inputs->MOUSE_INPUT
• midi cc handling is improved - no input lag and increased resolution (now full 8bit ( 0-128)
• video samples will always output audio (only over trrs, not hdmi) and audio-level is increased
• fixed a few recording bugs usb quality is improved and doesnt sometimes crash, still usb recording is v resource intensive - doesnt work well for hdmi outputs. also fixed bug where piCapture recording was being encoded at half framerate
• menus have page-up (FN + <) and page-down (FN + >) shortcuts
• default midi map is updated to align also with korgnanokontrol default arrangement and to flatten/expose some useful actions - more info here: default_midi_mappling
• now supports osc control - either by connecting recur to a shared network, or setting recur as an access-point and connecting your device directly to it, osc is enabled in settings->user_inputs->OSC_INPUT , and access-point is toggles with settings->user_inputs->ACCESS_POINT ; you can use the GET_IP menu to see what address you need to connect to. the access point is called r_e_c_u_r and the password is cyberboy666
• support for Guergana's r_e_m_o_t_e server extension - option to run a web server on the pi which can be accessed (by multiple simultaneous devices!) , currently set up to send actions (buttons and param values) , but also could be extended to do a bunch of other useful and fun things. can be enabled with settings->user_inputs->REMOTE_SERVER (note that osc must also be enabled) , then put the ip address into a web browser
• new plugins menu - merged from Tristans r_e_c_u_r fork, setting up a framework that allows community members to add functionality to recur without needing to dive too deep into the core codebase -> write external python scripts for your feature and add them in the pluginManager.. you can experiment with the existing plugins and read more about the ideas here

some new shaders

• white and black lumakey (x0 mix position, x1 switches key direction A -> B or B -> A)
• chromakey (x0 mix position, x1 key direction, x2 select hue)
• plus 2 displace shaders (1 input and 2 input). offsets a pixel in a direction based on its colour (x0 mix amount, x1 offset direction, x2 offset amount),
• spotlight and rgb_pallet shaders (inspired by Nichole's Scrawl project), spotlight is an 1input (despite being filed in the 0input folder whoop), which passes a circle (with x0 x-pos, x1 y-pos, x2 diameter, x3 trail), and rgb_pallet is a 0input source for spotlight that creates plain colour (with x0 r, x1 g, x2 b, x3 alpha)

note about wlan connection

if you have connected your recur to your home internet you may have needed to add your network name and password to a file /etc/wpa_supplicant/wpa_supplicant.conf ; now that we have two different connections wlan and access-point , you will need to add your home network to the file etc/wpa_supplicant-wlan.conf /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
