General requests

For general requests use "target" : "global" or omit "target" entry altogether.

Starting/pausing playback

{
"target" : "global",
"command" : "play"
}

Refreshing buffers

Fixes all possible issues.

{
"target" : "global",
"command" : "refresh"
}

Loading patch

"command" : either "open" or "load"; A "path" to .bro file should be specified.

{
"target" : "global",
"command" : "load",
"path" : "D:/pathces/pad.bro"
}

Changing BPM

"value" is expected to be a positive integer that could fit into 30 bits.

{
"target" : "global",
"command" : "bpm",
"value" : "240"
}

Cycling through ASIO drivers

Use this N times in case the default ASIO driver (and N-1 following drivers) suck balls.

{
"target" : "global",
"command" : "asio_switch"
}

#Device-specific requests

For device handling use "target" : device_type. Supported device types:

• Synth
• Transform
• Mixer
• Filter
• Handle
• Delay

Set "index" to specify the target device. Indices are 0-based, default "index" is 0. If no specified device is present, request is silently ignored.

For every control you want to set, add an entry to "state" array:

{
"control" : "control_name",
"value" : "value"
}

##Synth

• "freq" - synth frequency. Expects frequency value.
• "amp" - synth amplitude. Expects amplitude value.
• "function" - waveform function. Expects expression.

{
"target" : "synth",
"index" : "3",
"state" : [
{
"control" : "amp",
"value" : "0.5"
},
{
"control" : "freq",
"value" : "0.15"
},
{
"control" : "function",
"value" : "sin(x^2)"
}
]
}

##Transform

• "amp_in" - input amplitude ( amplitude value ).
• "amp_out" - output amplitude ( amplitude value ).
• "function" - transform function ( expression ).

##Filter

• "function" - filter frequency response function ( expression ).

##Mixer Instead of "control", specify "in" and "out" (integers) to pick a volume knob:

{
"target" : "mixer",
"index" : "2",
"state" : [
{
"in" : "1",
"out" : "0",
"value" : "0.5"
},
{
"in" : "2",
"out" : "2",
"value" : "-2.0"
},
]
}

Both "in" and "out" can be omitted and will default to 0.
