As with another article on sending OSC messages to and from Ableton Live that I posted (which was significantly more difficult to set up and get working), I’ve been since using Linux with Sonic Pi and REAPER to do the same.
My goal was to have a way to record stems from whatever code blocks (usually live_loop) to separate tracks for later mixing. Turns out REAPER is incredibly efficient, works on Mac, Win, and Linux and is inexpensive. Plus, the built OSC commands available can control pretty much anything in REAPER.
Obviously, install REAPER and Sonic Pi first.
REAPER has OSC built in. Go to the preferences in REAPER and on the left column scroll down to ‘Control/OSC/web’:
Click the ‘Add’ button.
Use these settings, noting that the Device name can be whatever you want. The local listen port your can choose as well. The Device IP I left blank, but if you were sending to another computer, you’d want to fill that in, and then find your computer IP number and enter that in Local IP: (I find it has been safest to put the actual IP in and not local host. I also check the “Allow binding messages to REAPER actions and FX learn” which I believe are for custom OSC commands that you want to use, but haven’t tried that yet.
NOTE: a cool feature is to use the “Listen” button in that window. This traces all OSC commands coming in which excellent for testing.
In the Pattern config dropdown choose (open config directory):
From that directory open the “Default.reaperOSC” file which is a reference to all of the commands. The current one is:
# Make a copy of this file, rename it, and edit the file to create a
# custom pattern configuration.
# For basic information about OSC and REAPER, see

# Default values for how this device behaves. The device has a selected track, bank
# of tracks, and FX, which are not necessarily the same as the selected track or FX
# in the REAPER window.
# REAPER_TRACK_FOLLOWS determines whether the selected track in REAPER changes
# only when the user changes it in the REAPER window, or if it follows the track
# currently selected in the OSC device.
# Allowed values: REAPER, DEVICE
# DEVICE_TRACK_FOLLOWS determines whether the selected track in the device changes
# only when the device changes it, or if it follows the last touched track in the
# REAPER window.
# Allowed values: DEVICE, LAST_TOUCHED
# DEVICE_TRACK_BANK_FOLLOWS determines whether the selected track bank in the device
# changes only when the device changes it, or if it follows the REAPER mixer view.
# Allowed values: DEVICE, MIXER

# Each line below is an action description in all caps, followed by a number of OSC
# message patterns. You can add, remove, or change patterns, delete lines, or comment
# out lines by adding '#', but do not change the action descriptions.
# The patterns following the action are the messages that REAPER will send and receive
# to and from the OSC device. An action can have no patterns (and will be ignored),
# one pattern, or many patterns.
# The patterns may contain the wildcard character '@'. (This is REAPER-only, not part
# of the OSC specification.) The '@' wildcard is used to specify the action target.
# ----------------------------------------------------------------
# The OSC device sends patterns to trigger actions, and REAPER sends patterns to the
# device as feedback. OSC patterns can include arguments, which are be interpreted
# in various ways, defined by a flag immediately before the pattern.
# n: normalized floating-point argument. 0 means the minimum value, and 1 means the
# maximum value. This can be used for continous controls like sliders and knobs.
# Example: TRACK_VOLUME n/track/volume n/track/@/volume
# The device sends /track/3/volume 0.5 to set the volume to 0.5 for track 3, or
# /track/volume 0.5 to set the volume for the track that is currently selected in
# the device. REAPER sends /track/3/volume 0.5 when track 3 volume changes to 0.5.
# If track 3 is currently selected in the device, REAPER will also send
# /track/volume 0.5. The floating-point argument represents as the track fader
# position in the REAPER window. 0 sets the fader all the way down, 1 sets the fader
# all the way up, 0.5 sets the fader exactly in the middle. Therefore, the actual
# volume that is set depends on the REAPER track fader preference settings.
# f: raw floating-point argument. The argument is interpreted directly, to set or
# report a value.
# Example: TEMPO f/tempo/raw
# The device sends /tempo/raw 100.351 to change the REAPER tempo to 100.351 bpm.
# REAPER sends /tempo/raw 120 when the tempo changes to 120 bpm.
# Normalized and raw floating-point arguments also support multiple parameters
# sent from the device.
# Example: FX_PARAM_VALUE n/track/@/fx/@/fxparam/@/value
# The device can send /track/3/fx/1,2,5/fxparam/6,7,7/value 0.25 0.5 0.75
# to set three FX parameter values at once, to 0.25, 0.5, 0.75 respectively.
# b: binary argument, either 0 or 1. The device sets or clears the state when
# sending the message. Can be used to emulate switches or momentary controls.
# Example: TRACK_MUTE b/track/mute b/track/@/mute
# The device sends /track/3/mute 1 to mute track 3, or /track/mute 1 to mute the
# track that is currently selected in the device. /track/3/mute 0 will unmute
# track 3. REAPER sends /track/3/mute 1 when track 3 is muted, and /track/3/mute 0
# when track 3 is unmuted. If track 3 is currently selected in the device, REAPER
# will also send /track/mute 1 and /track/mute 0.
# Example: REWIND b/rewind
# The device sends /rewind 1 to begin rewinding, and sends /rewind 0 to stop
# rewinding. REAPER sends /rewind 1 when the rewind button in the REAPER window is
# pressed, and /rewind 0 when the button is released.
# t: trigger or toggle message. The device triggers the action, or toggles the
# state, when the pattern is sent with no arguments, or with an argument of 1.
# The feedback values REAPER sends are identical to those sent for binary
# arguments.
# Example: METRONOME t/click
# The device sends /click or /click 1 to toggle the metronome on or off. REAPER
# sends /click 1 when the metronome is enabled, and /click 0 when the metronome
# is disabled.
# r: rotary. The device triggers the action in the forward direction when sent
# with an argument greater than ROTARY_CENTER, and in the reverse direction when
# sent with an argument less than ROTARY_CENTER. For some messages, the magnitude
# of the argument affects the rate of change. REAPER does not send feedback for
# these messages.
# Example: SCRUB r/scrub
# The device sends /scrub 1 to scrub forward, and /scrub -1 to scrub in reverse
# (if ROTARY_CENTER is 0).
# s: string. These messages include a string argument. Many of these messages
# are sent from REAPER to the device for feedback/display, but some can be sent
# from the device to REAPER.
# Example: TRACK_NAME s/track/name s/track/@/name
# The device sends /track/3/name "vox" to rename track 3 in REAPER, or /track/name
# "vox" to rename the track that is currently selected in the device. REAPER sends
# /track/3/name "vox" to report that name of track 3 is "vox". If track 3 is
# currently selected in the device, REAPER will also send /track/name "vox".
# Example: DEVICE_FX_FOLLOWS s/fxfollows
# The device sends /fxfollows "FOCUSED" to inform REAPER that the selected FX in the
# device will now follow the FX that is focused in the REAPER window.
# i: integer. These messages include an integer argument, and are sent from the
# device to REAPER.
# Example: ACTION i/action t/action/@
# The device sends /action 40757 or /action/40757 to trigger the REAPER action
# "split items at edit cursor". See the REAPER actions window for a complete list
# of action command ID numbers.
# Example: DEVICE_TRACK_BANK_SELECT i/bankedit t/bankedit/@
# The device sends /bankedit 2 or /bankedit/2 to inform REAPER that the active
# track bank is bank 2. If NUM_TRACKS is 8, that means REAPER will now interpret
# a message like /track/1/volume as targeting the volume for track 9, and REAPER
# will only send the device feedback messages for tracks 9-16.
# ----------------------------------------------------------------
# Note: the default configuration includes a lot of feedback messages, which can
# flood the device. Avoid flooding by removing messages (by deleting the patterns,
# or commenting out the lines) that the device does not want, especially the
# TIME, BEAT, SAMPLES, FRAMES, VU, FX_PARAM, LAST_MARKER, LAST_REGION messages.
# Note: FX parameter feedback will only be sent for the track that is currently
# selected in the device. If messages exist that can target FX on other tracks,
# feedback will be sent whenever the parameter values change. This can be a lot of
# data, so only include those messages if you want the feedback.
# Example: FX_PARAM_VALUE /fxparam/@/value /fx/@/fxparam/@/value
# This action can only target FX on the currently selected track, so feedback will
# only be sent for that track.
# Example: FX_PARAM_VALUE /fxparam/@/value /fx/@/fxparam/@/value /track/@/fx/@/fxparam/@/value
# This action can target FX on any track, so feedback will be sent for all tracks.
# Note: multiple patterns for a given action can all be listed on the same line,
# or split onto separate lines.

NOTE: it took me a bit understand this file. It lists the constants for REAPER in the all capital letters with underscores. Then it has something like t\record. The ‘t’ and other letters are for which type of value each command expects, but you leave off the preceding letter and rather use that type of value at the end of your OSC command. It it explains all of this in the begging comments of the file.
Then in Sonic Pi you can define a function and call it just before your actual music blocks:
define :osc_setup do
use_osc "192.168.1.66", 7771
osc "/tempo/raw", current_bpm
osc "/track/1/recarm", 1 #arm track (1 is for yes)
osc "/track/2/recarm", 1
osc "/track/3/recarm", 1
osc "/track/4/recarm", 0 #don't arm track (0 is for no)
osc "/track/5/recarm", 0
osc "/track/6/recarm", 1
osc "/time", 0
osc "/restart", 1
osc "/record", 1
end
use_debug false
use_bpm 140
# Run the osc setup function
osc_setup
That’s really it for getting Sonic Pi to Send to Reaper.
To record, you will need to do several things.
Make sure you have some system level audio patcher, like Loopback or Blackhole on Mac, and Jack on Linux. With both apps open you need to wire the 16 Supercollider (Sonic Pi) channels to the 16 inputs of REAPER. I’ve left the 1 & 2 as the main outs, but wire 3 - 16 from Supercollider to REAPER. These are mono channels. Here is an exmaple in Jack using Claudia to manage the patching on Linux:
Then make as many tracks as you need in Reaper. Set the inputs to the mono or stereo tracks you just set up.
Then in Sonic Pi, wrap whatever you want to send to one of those track numbers in REAPER with a with_fx :sound_out, or :sound_out_stereo, something like this:
with_fx :sound_out_stereo, output: 3 do
live_loop :test do
play scale(:D2, :minor_pentatonic).choose
sleep 1
end
end
I tend to output stereo so it needs to be every odd channel (i.e., 3 is actually 3 and 4 in stereo, my next output is 5 - but 5 and 6 in stereo).
If set up this way, the above code should arm all tracks and start recording when you run your code in Sonic Pi.
and no problem
