NEW!: Bela hardware support added with ultra low latency

Cloud Instrument

Custom MIDI Controller plus embedded hardware running Supercollider as a synthesizer and effects processor. Using an external USB sound card for high fidelity.

Powered by API.Cultor MIR retrieving OSC service.

Supported hardware:

• Raspberry Pi 3 (model B)
• Bela (recommended for ultralow latency)

Physical controller:

Built by Yaeltex custom MIDI controllers.

How to perform with it?

See the User Guide for more details.

Configuration

• Install dependencies (Linux, MacOS, Windows or raspberry pi)

• Create a config file with Freesound api key (or config another database service)

  For Freesound: APIv2 APPLY (and use this callback https://www.freesound.org/home/app_permissions/permission_granted/) And we get something like: API_KEY = "asga2823235r48qklasdjl3khfasdflk2"

  Then create a file named ".config.json" in the raspicultor/ path: { "sound.synth": "supercollider", "api": "freesound", "Freesound.org": [ { "API_KEY": "" } ] }

• Run ./CloudInstrument.py

• If you are going to use SuperCollider run first. Note: sends broadcast OSC message to the network. $ sclang -D apicultor_synth.scd

• Run OpenStageControl with ui/apicultor-ui.json (osc receiving port 7000)

• Play with it! Describe sounds with MIR descriptor search them in the Cloud, then use integrated realtime processes with them (granular synth, reverb, delay, LP/HP filters, etc).

Dependencies: INSTALL.md

Use

FX Chain

    freeze -> vibrato -> pan-> pithshift -> filters -> delay -> reverb
