ZZZ
SuperCollider classes to interface with Expert Sleepers devices.
Features
- SynthDefs for specific types of signals (clock and gate).
- Class methods to convert between MIDI notes, frequency, amplitude and corresponding output voltage.
- Instance methods to add, set and remove clock and gate signals on specific hardware outputs.
- Documentation (in .schelp format) for the ZZZ, ZZZDevice and ZZZError classes.
Installation
The classes are an extension of the SuperCollider language (sclang), therefore their installation corresponds to how Quarks are installed.
Usage
To create an object interfacing your hardware device, instantiate the ZZZDevice class with an Array of Integers representing your eight ADAT channels connected to the module and the server instance in use:
// RME Babyface example, when creating output bus channels for all hardware // outputs of the audio interface ~device = ZZZDevice.new(server: s, channels: Array.series(8, 4, 1));Note
The instantiation of ZZZDevice conveniently makes the outputs of the device available in a numbering range from 1-8 (as displayed on the hardware).Generally, in SuperCollider channel numbering starts with 0, though!
To interface with your module on one of the eight outputs, you can make use of the SynthDefs added by the ZZZ class:
// create a tempo (240bpm), which can be used by e.g. multiple clocks on outputs ~device.addTempo(slot: 1, tempo: (240/60)); // the tempo can be changed manually ~device.setTempo(slot: 1, tempo: (180/60)); // start clock on output 8 using the tempo at slot 1 ~device.addClock(output: 8, slot: 1); // remove the clock ~device.removeClock(output: 8);// start a gate on output 7 ~device.addGate(output: 7);
Both tempos and gates can be altered using control Busses exposed in .tempoBusses and .gateBusses (respectively).
Background
Modular synthesizers are controllable through several ranges of voltage.
However, CV/ Gate <https://en.wikipedia.org/wiki/CV/gate> as defined by
Doepfer in the A100 manual might not be used coherently
throughout all Eurorack modules.
The ZZZ classes nonetheless try to adhere to the standard, while at the
same time providing convenience functions to low-level conversion.
By default the helper functions are able to convert frequencies in the range
of twelve octaves
(between C-2 and C10) to an output between -5V and 7V (adhering to the
1V/octave scheme) - the MIDI note range being a subset of it.
As the range is not fixed, but can be moved up and down (e.g. when using
filters or oscillators), you might have to make some adjustments to your
module, to get "in tune".
